About
The player creates a character and follows the story of a student at Hogwarts School of Witchcraft and Wizardry, and throughout the game will have to make certain choices which determines the path their character will be placed on, including the kind of relationships they build with other characters. Along with the story side told through each chapter, they have the opportunity to achieve rewards by learning spells and potions.

Beginning in 1984, the story follows the character for seven years of education. In that time, the game will feature characters known from the books during their student years, including Bill Weasley, Charlie Weasley and Nymphadora Tonks. The game also features teachers who were working at Hogwarts during that time including the characters of Rubeus Hagrid, Severus Snape, Minerva McGonagall, Albus Dumbledore, Filius Flitwick and Rolanda Hooch.

Chapter 1: Your Journey Begins
The player begins by creating the appearance of their character before arriving at Diagon Alley where they are introduced to Rowan Khanna. Rowan advises the player to purchase their books from Flourish and Blotts. The player later rejoins Rowan and names their character and establishes a friendship with Rowan.

Finally, the character purchases their wand from Ollivanders. The player finds out their character has a brother who went missing and depending on the answer the player selects in response, they will receive one possible wand wood and core out of three possible ones.

Chapter 2: Welcome To Hogwarts
The player arrives at Hogwarts where they gather in the Great Hall. The Sorting Hat will ask the player which house they were hoping for and then place the character in their house of choice, which will be the same house Rowan was placed in. They will then head to their common room where they will talk with Rowan before attending Charms and Potions where they will encounter bully Merula Snyde and have the choice of how to deal with her.

Chapter 3: Dealing With Trouble
The player will be introduced to Ben Copper and the Prefect of the House the player chooses. The player and Rowan depending on whether the player wants Rowan to join them, will be tricked by Merula and attacked by Devil's Snare. They are rescued by Rubeus Hagrid and then attend their Flying class where the player received another opportunity to create a friendship with Ben.

Rowan then invites the player to play Gobstones and the player's choices in the game determines how it works out. Later Merula finds them. Merula taunts the player with research she found about the player's brother who people think run away to join the Death Eaters. Depending on the choice of the player, they can respond with information which reveals Merula's parents were Death Eaters. Merula then challenges the player to a duel.

Chapter 4: Revenge is Best Served Magical
The player reports to their House Prefect who offers to teach the player to duel when they have learned a duelling spell. They find the secret duelling book in the Artefact Room and the player receives information about the Cursed Vaults their brother went looking for. The player then has an opportunity to talk with Rowan about what the player found out and build their friendship with Rowan depending on their choices.

The player will then begin improving their duelling in preparation for the duel with Merula. Professor Flitwick was known to be a duelling champion, and Flitwick agrees to help the player improve their skill at duelling by teaching them one spell. Flitwick then tells the player they can only use the spell for self-defence and they should ask Ben for help in order to learn another spell.

The player finds Ben in the Great Hall where they have the chance to cheer Ben up and improve their friendship. However, Rowan finds a spell in the duelling book and the player learns the new spell. Rowan then lets the player try the new spell on them and it works, and they agree to report their findings to their house Prefect.

Chapter 5: The Duel
The player reports their new skills to their House Prefect and is asked to duel Rowan for practice. The game offers three choices for how to duel: Sneaky, Defensive and Aggressive. Both Rowan and the player choose one of the three; depending on the choices, one will defeat the other. Having won the duel, the player finds Merula bullying Ben in the courtyard.

Merula attacks Ben with a spell and the player feels they have no choice and have to decide on the way they will intervene. They have the choice of attacking before Merula or defending when Merula attacks them. Merula and the player then duel and the player will win. Professors Snape and Flitwick then arrive and Snape blames the player for beginning the duel.

However, depending on the earlier choice of the player Flitwick will ask the player whether they were the one who began the duel. If they had not Flitwick will defend the player and Snape will demand the player receives detention anyway for learning defensive spells.

Chapter 6: A Curious Corridor
The player meets Penny Haywood who says thank you to them for dealing with Merula. Penny offers to help the player when they need it. The player and Merula then find Snape who tells them he would make them leave the school for their actions but Albus Dumbledore would want them to receive detention. They are then interrupted by Argus Filch who mentions a vault in a corridor to Snape, who then leaves to investigate.

Merula deduces they are talking about the cursed vaults and follows them and the player then decides to follow Merula. Snape asks Filch who else knows about the vaults and ice and then decides to inform Dumbledore and deduces it may be connected to the player's brother. The player wonders why Merula would be looking for the vaults and then tells Rowan what happened.

The player has the choice of how to tell Rowan what happened, and persuade them to join the plan the player created to find out more about the cursed vaults and cursed ice. They then head to the corridor where they search for any clue which may lead them to the vaults. They eventually decide to open a door leading off the corridor, only to find the door was locked. They hear a noise and abandon the locked room.

Chapter 7: Class Matters
The player meets with their House Prefect who asks them to focus more on school work for a while and make up for the House points taken from them through their rule-breaking.

Part of the classes section of the chapter was to learn the spell Knockback Jinx. However, Flitwick taught the player a duelling spell already and tells them they cannot learn another one. The player can respond with a choice of three possible answers which determine whether they can persuade Flitwick to let them learn Flipendo.

In Potions, Merula asks the player whether they told anyone about what they heard in the corridor. The player can tell the truth or lie. The player then asks Merula again why she wants to find the cursed vaults and she refuses to tell them. The player later reminds Merula they need to rotate their potion two more times and they will be rewarded with ten points.

Chapter 8: Preparing for the Room
The player's House Prefect will now be happy with the effort and Rowan decides to ask the player about the locked room. The player creates a plan to knock Mrs Norris out with a Sleeping Draught in order to reach the door unnoticed. Then they will use the Unlocking Charm to open the door. Finally the spell Flipendo will help them escape if they are trapped in the room.

The player decides to ask Penny Haywood to help them create the Sleeping Draught. They decide they need the help of a third person with the task and the player picks between Ben and Penny to bring. The player talks to Penny in the Potions Classroom and she agrees to help them create the Sleeping Draught. Penny can either be told why you are making the potion or she can be lied to.

The player thanks Penny for helping, and then Penny or Ben (depending on the choice of the player) tells the player they should talk tonight about the secret mission Rowan told them they wanted their help with. The player and either Penny or Ben talk about the plan and they wonder why the player would want them to help. The player can respond with three possible answers which may improve their friendship. The player then persuades them to help.

Chapter 9: Inside the Room
The player heads to meet Rowan and either Penny or Ben in the corridor of the locked room. On the way, Filch apprehended them and asked them what they were up to. He mentions their trouble-maker brother, Jacob and the player can trick Filch into walking away from the corridor.

The three of them gather in the corridor where Mrs. Norris was guarding the door. Rowan puts Mrs. Norris to sleep using the Sleeping Draught dosed in milk and then the player opens the door with the Unlocking Charm. Merula then overpowered the group and tells them she will be the one who finds the Cursed Vaults before anyone else.

The player decides what to do about Merula. They follow Merula only to find she was trapped by the Cursed Ice which was growing and Merula begs them to help her. The Cursed Ice trapped the four of them in the room. The player begins saving them and decides whether they should help Merula.

However, when they have saved everyone they cannot reach the door. If the player chose Penny, she will reveal she made the Strengthening Solution and drinks it, before preceding to break the ice. If the player chose Ben, they will encourage him to cast a Knockback Jinx on the ice to break it. Before they left the room, the player noticed the writing in codes on the wall which Rowan says she will remember.

The player and Rowan wonder what the room was and what happened to the Cursed Vault they thought would be in the locked room. Rowan says perhaps the code will help them when they decipher it.

However, the school including the Prefect find out that the four of them went to the forbidden corridor and found the ice. The player can tell the Prefect the truth or lie. The Prefect reminds the player they represent their house even though they understand they need answers about what happened to their brother. They then tell the player that Dumbledore wants to talk to them later.

On the way to talk to Dumbledore, Rowan tells the player they found out what the code said about the ice knights who guard the Vanished Stairs. Rowan says they will work it out by the second year. When the player talks to Dumbledore, the player's surprised when he was kind to the player.

The player tells him why they broke the rules, and he tells them they can not only stay for their second year but that he thinks what they found will make sense in the future. He praises their actions and awards them one hundred points for their house (if you are in Gryffindor you don’t get one hundred points for your house). He warns them to be considerate about their choices in the future and the impact they have on other people, telling them he will talk to them about the Cursed Vaults and their brother another time.

Chapters 10 & 11: Year's End
The player attends the End-of-Term Feast where they find out whether their House won the House Cup. The player will be rewarded with one hundred gems and then head home for the summer holidays.

Chapter 1: Year Two Begins
At the Start-of-Term Feast, Merula Snyde tells the player she will continue trying to find the Cursed Vaults. Rowan Khanna asks the player whether they had a good summer and the player has the choice of how to respond. They both tell each other about the research they made about the Cursed Vaults and the Vanished Stairs and Rowan tells them they found out about staircases which no longer appear to be at the school.

The player says they should find Penny Haywood and Ben Copper and ask them to help search for them. They hear Professor Dumbledore's speech who warns the school they need to tell a teacher if they notice anything odd around the school. The player asks Penny to help them and whether she knows where to find Ben. Penny notes she's worried about Ben because he went missing when they arrived.

They ask everyone around the Great Hall whether they know where Ben went. The answers are very vague, mentioning certain places they think they saw him or simply saying they need to talk to him when they find him. The player then decides what to do. They have the option of asking Professor McGonagall who's the Head of Ben's house.

Merula tells the player she knows what happened to Ben and that she knows about things which go missing, and that trying to uncover those things leads to people being killed. The player has to option of asking whether Merula's implying she knows about Jacob or the Cursed Vaults. The player asks whether Ben went looking for them and Merula says they will find out eventually.

The player meets with Professor McGonagall who says she needs to speak to Ben when they find him. She says Ben's well-being was very affected by what happened to him with the cursed ice (even if the player took Penny and not Ben,) and she warns the player they need to consider everyone else in their pursuit for answers.

She asks the player to tell her the truth about what they found in the Locked Room. The player decides whether to tell her. If the player decides to tell the truth, McGonagall says she will share in the info about the Ice Knights and Vanished Stairs with Dumbledore.

McGongall then surprises the player by mentioning the Cursed Ice incident has happened before, but refuses to elaborate and says it's not important. She tells the player to search for Ben in every known hiding place for clues for his whereabouts and report to her if they find him, and she will reward them for their efforts.

The player and Rowan search the corridor for Ben and realised one of the cupboards were locked. They open it with the Unlocking Charm and find a note which they think belongs to Ben. It's written in another code which Rowan agrees to decipher. They gather in the common room to read one of the books which Rowan says can help them decipher the code.

Rowan deciphers the words and tell the player the next clue was transfigured into a quill which was hidden in the common room of another House (the Gryffindor Common Room for Ravenclaw and Slytherin and the Slytherin Common Room for Gryffindor and Hufflepuff), and failure to follow the clue will be severely punished. It was signed by the initial R. The player and Rowan decide they need to sneak into the other common room despite not from that House. They then work on how to undo the transfiguration.

Chapter 2: Growing and Shrinking
The player and Rowan talk about Ben and the plan to find the object which could lead them to Ben. Rowan says when everyone attends the Gryffindor and Slytherin Quidditch game, they will sneak into the empty House Common Room using the Shrinking Charm and then the Growing Charm. Rowan warns the player the House Prefect will be very smart and find them searching the room. The player says they will take care of the Prefect.

On the way to one of the classes, the player encounters the Prefect of the House that would later be sneaked into, and has the opportunity to decided whether or not to trick them. They learn Reducio and have the chance to tell Professor Flitwick the truth about why you are asking about it. He warns them not to use it outside of the class. Rowan tells the player they are worried they are too late to save Ben. The player then cheers Rowan up and persuades them both the plan and Ben will be fine.

Chapter 3: The Black Quill
On the day of the game, the player and Rowan watch two people in the other House head to the game. Before the door shuts, the player uses the spell Reducio and sneaks in. They then use the spell Engorgio to be their normal size again before searching the room. They find the object and then head back to Rowan where they were apprehended by the Head of House who saw them.

The player depending in their choice will either lose House points or tell the Head of House they were searching for their friend and will be allowed to go and tell them never to sneak in another House's room again. They head back to their own room and talk about what they found. They untransfigure the object and read the note. It tells them to search one of the corridors and they wonder whether the note involves anyone else.

Rowan wonders whether they should continue and the player decides whether to take Rowan or Penny. If the player takes Penny, Rowan will be sent to tell one of the teachers what they found. The player and Rowan or Penny search the corridor and find Professors Snape and McGonagall have discovered Ben stuck in the cursed ice. Snape and McGonagall eventually manage to free Ben from the ice, leaving the player to wonder what happened.

Chapter 4: Revelio
The player visits Ben in the Hospital Wing and encounters Poppy Pomfrey, who relays that Ben is in great distress and heavily hints she'd like you to leave unless you have a good excuse to see him. Depending on how high your Empathy level is, you'll be able to tell her you came to comfort Ben and she'll allow you to stay. When the player approaches Ben, he'll be relieved that you came to visit him but he'll act odd. He will tell you that he doesn't remember asking for you or even being trapped in the ice. The player will decide that if they cannot get any information from Ben, they will meet Rowan back in the corridor and find out what happened themselves.

When the player returns to the corridor with Rowan, Rowan tells the player that they are suspecting Ben is hiding something from them because he is either scared of what he found or he's trying to protect both of you. You have the choice to trust Ben, agree with Rowan, or be unsure. Both of you proceed to search the corridor once more and find the wall to be suspicious. Both of you conclude that you need to learn the revealing spell, Revelio, and that you know how to learn it. The player will approach Professor McGonagall in her classroom to ask for a favour.

Depending on if you told her about the secret message or not, she'll reward you 20 house points for your help and showing concern for Ben. The player then proceeds to push for that private lesson with McGonagall to learn the advanced charm. She'll tell the player she thinks the charm is too complicated for them, and has to see that you're skilled enough when you attend class. Once the player completes attending Transfiguration class, McGonagall will find you worthy of learning Revelio.

Rowan will congratulate you and ask for the player to meet them back at the Icy Corridor again. The player and Rowan have some small talk about what to expect before casting the spell. The player casts Revelio on the wall and reveals a hidden staircase - very much like the player's vision.

The player now has the choice to either proceed, proceed with caution, or tell a professor about their newfound discovery. If the player suggests telling a professor, Rowan will warn them that the professor would never let them back into the corridor. They remind the player that this is an important hidden discovery at Hogwarts and they should seize the opportunity to explore. The player casts Lumos and they venture off into the staircase.

Rowan mentions the room is unnaturally cold, and the player believes they are close to the Cursed Vaults. When they find a door covered in ice, Rowan will approach it. The ice will send Rowan flying and they will be injured. The player then takes them to the Hospital Wing.

Chapter 5: Rowan's Recovery
The player visits Rowan in the hospital wing and finds Penny there. Penny tells the player that if she was there she could've helped. The player agrees that they should bring Penny along next time.

During a Potions class, Merula tells the player that she has been working with else to find the cursed vaults. Snape tells the player that he has searched their dormitory and challenges the player about potions ingredients that he found there. The player has the chance to blame Merula (providing they are of a high enough level), or take the blame themselves (and risk losing 50 points).

The player visits Rowan in the Hospital Wing again and Rowan tells them to focus on their classes. Rowan says that they don't want to go near the cursed vaults ever again. Later Merula hints she knows things about Jacob, and the player persuades Rowan to keep helping with them with the Cursed Vaults and Rowan tells them they should bring Bill Weasley onboard.

Chapter 6: Bill Weasley
The player finds Bill on the training grounds practicing defensive spells. Luckily Bill has already heard of the player and their brother. He agrees to help the player find the Cursed Vaults, though he tells them they need to improve their Transfiguration and dueling skills. A duel with Bill takes place in the Training Grounds after the player perfects the Softening Charm. Upon winning the said duel, Bill and the player relocates to the Clocktower Courtyard where he shares one of his favourite spells, the Fire-Making Spell, and asked the player to study the spell in The Standard Book of Spells before he teaches the spell in person. After studying the spell with Rowan in the common room, a practical training with Bill begins, during which he reveals being keen on becoming Head Boy.

Chapter 7: Facing the Door
The player meets Bill in the corridor. Bill is excited to start his first curse breaking adventure. The Player and Bill decide to move through the corridor fast so the cold won’t affect them too much. When they get to the vault they find even more ice in the way. The player has the option of casting flipendo or incendio on the ice. After getting through the ice blocking the door the Player and Bill come face to face with the door to the vault. Bill believes that they should work on attacking the door before it has a chance to attack them. After working together to defeat the door traps Bill within more cursed ice. The player frees Bill from the ice but Bill is too weak to continue.

Chapter 8: Training the Team
Once the player reaches this chapter they get a message from Bill telling them that he still doesn’t feel good and is in the hospital wing. The player’s prefect asks them to meet him or her in their house common room. The prefect is worried about the player and their effect on their house. The prefect tells the player they should change into new clothes. Bill is released from the hospital wing and wants to make new plans for breaking into the cursed vault. The player works on training Rowan, Penny, and Ben. Rowan needs to learn incendio. Penny already knows incendio but wants to work on the knock back jinx. Ben needs to learn how to make a healing balm for burns.

Chapter 9: Wizards Unite!
Hagrid informs the player that the cursed ice has spread throughout Hogwarts and students are trapped. Hagrid also mentions that Dumbledore is away searching for a famous curse breaker. The player meets Bill in the courtyard and they decided to only bring one other friend along so the others can help the professors free other students. The player will have to decide if they want to bring Rowan, Penny or Ben along with them. The player meets their chosen friend in the great hall to convince them to join the adventure.

Chapter 10: The Vault of Ice
The player, Bill and the chosen friend (Rowan, Penny or Ben) meet in the courtyard before heading to the vault. The three take turns casting incendio at the door until it opens. When the door starts to open Bill has the sudden realisation that the door might not be keeping them out, but keeping something in. An ice knight bursts from the door and traps Bill then your friend in ice. The player will duel the ice knight and then free their friends. They open the vault where they find a notebook and broken wand and a voice tells the player never to let "her" find the other ones. After leaving the vault McGonagall demands that the player meet her outside of Dumbledore’s office. She is furious at the player and unless the player took Ben along, who is good at hiding evidence, takes 50 points from the player’s house. The player goes to meet Dumbledore in his office where he is busy writing a letter. Once he finishes he tells the player not to keep looking for the cursed vaults but gives the player 50 points for their bravery. He tells the player that they have something important to talk about at the end of next year.

The player returns to Hogwarts and meets with Rowan, Penny and Ben in the great hall. They are worried that Dumbledore is angry with the player. The player doesn’t think that Dumbledore is angry with them but changes their tune after hearing his speech. Dumbledore addresses the school and confirms the existence of the cursed vaults. He says that the cursed ice was the unique curse placed upon one of the vaults and that each vault contains another curse. The cursed was only unleashed when a student tampered with the vault but fortunately that student was able to enter the vault and break the curse. He warns the students not to go around tampering with the vaults again and that if they do consequences will be severe, especially for repeat offenders. Rowan asks if they think they should keep looking for the vaults or obey the rules. At the end of Herbology, Penny discovers a werewolf in the pots, which is actually a Boggart. Before the Flying class, Tonks and Rowan talk about the upcoming visit to Hogsmeade. The player will be told by the Head of House they need to focus and improve their school work if they want permission for Hogsmeade trips.

Chapter 2: Boggarts and Butterbeer
The player meets Bill and Penny in the great hall where Bill shows off his new prefects badge. The player is concerned about Penny after her run in with the beggars. Bill tells the player to ask Hagrid about the Boggart found by Penny in Herbology. Hagrid connects the Boggart to the vaults, telling the player they appeared in the school when Jacob went searching for them. The player and Rowan wonder why Penny was afraid of werewolves, but Penny had no idea why and they eventually decide it's simply a dark creature people would be afraid of.

Chapter 3: Three Broomsticks
The Head of House tells the player they are impressed by their work, and tell them they may have permission for Hogsmeade trips. The player learned from Hagrid that Jacob went to the Three Broomsticks and knew Rosmerta very well, and the player will want to talk and find out what Jacob may have said. Rowan tells the player to meet them at the pub when it's time.

The player heads to Hogsmeade where they are introduced to Andre Egwu. They then find Rowan and Hagrid in the Three Broomsticks. They order Butterbeer and Rosmerta says she will be back in a minute. The player finds out Jacob would write in notebooks until one day, Aurors took Jacob away. Rosmerta then tells the player they can look for the object Jacob hid if they agree to help out at the Inn.

When the player works a shift at the Inn, Rosmerta says she needs more time to find the object and the player decides whether they want to help Rosmerta create a new kind of Butterbeer. If they do, Rosmerta will tell them to find a Sugar Plant and Mallowsweet ingredient, along with Moondew.

If the ingredients are collected correctly, Rosmerta will tell Dumbledore she thinks the player should be rewarded ten House Points. If the ingredients are wrong, including the player growing the wrong plant in Herbology, they will not receive any House Points and many wizards will feel sick from poison when they drink the butterbeer concoction.

Rosmerta rewards the player with Jacob's quill which they untransfigure and find it's a notebook. Filch will then appear and take the notebook from the player, telling them they are breaking the rules by continuing with their search.

Chapter 4: Filching from Filch
The player has to get back Jacob's notebook from Filch's office. The player will seek the help of Nymphadora Tonks, who agrees to find a way to sneak into the office. Tonks and the player visit Zonko's Joke Shop in Hogsmeade, where they formally meet the shopkeeper, Bilton Bilmes.

After telling him of their pranking schemes, he presents them with the choice of two different top selling products: the Nose-Biting Teacup or the Fanged Frisbee. Later back at the castle, Tonks will find the player when Filch has left his office, giving them time to sneak in and look for Jacob's notebook.

Chapter 5: Tulip Karasu
The player meets Rowan in your House's Common Room after retrieving your brother's notebook from Filch in order to see if they can help you decipher it. The player decides to take Bill, Penny or Ben to find Jacob's secret room which he used for his research. They find a padlock with two keyholes and you have the option of using Alohomora or Flipendo. They find Tulip in the Transfiguration classroom because her name is on the lock. You have the option to ask nicely or make her help. The next task is to disable the Dungbomb to gain Tulip's assistance.

Tulip informs you that her accomplice is Merula and she has the other key. To build up friendship points, she asks why should she work with you and you have the option of three choices, before paying a certain number of coins in order to persuade Tulip she should work with you. After learning Duro and the Antidote to Common Poisons, the player meets with Tulip in the Courtyard to form a plan to distract Merula's friends.

Chapter 6: The Letter from No One
Tulip tasks the player with retrieving the Jumbo Dungbomb from the owner of Zonko's Joke Shop, Bilton Bilmes. The player explores the shop while Bilton hunts for it in the back. He offers to give you the rare Jumbo Dungbomb in exchange for baby Mandrakes and rare sweet Butterbeer 1707 from the Three Broomsticks. Madam Rosmerta fetches the Butterbeer while the player tends to her customers.

The player then meets Rowan in the Common Room because they found a letter from "a friend" on the player's bed, warning they are in danger. Rowan asks who they think sent the letter and the player decides from the choice of Merula, Dumbledore, or not sure. The player then focuses on Tulip and the Jumbo Dungbomb, and collects the baby Mandrakes.

Bilton finds the Jumbo Dungbomb and Tulip creates the Ultimate Dungbomb with it. The player and Tulip find Merula and Merula's cronies in the Courtyard. They throw the Dungbomb at them, which makes every except Merula run away. Tulip and the player confront Merula for the other key. Merula says if the player duels her again and wins, they may have the other key.

The player and Merula duel. When the player eventually wins, Merula lets them take the key and says that it’s okay because she found what she wanted from the Jacob's room earlier. Merula then tells the player they should watch out because Tulip will betray them.

Chapter 7: Jacob's Room
Tulip tells the player to ignore Merula when she told them she took what she wanted from the room, because Tulip knows she and Merula found nothing worth taking. They then unlock Jacob's room only to be confronted with the player's Boggart which takes the image of Voldemort. They run away and decide they need to learn the Boggart-Banishing Spell before entering the room again.

They search for books in the Library and ask Madam Pince where they could find them. They then search in the back and eventually find the book they needed. Tulip wonders why the Boggart took the image of Voldemort, and the player decides it's because of what happened to the Potter family, to their brother or because he's terrifying.

The player and Tulip have read about the spell and find another Boggart in Ben Copper's hiding place, where they practice the spell. Tulip faces the Boggart which takes the image of Merula, and the player banishes it. They then speak in the Great Hall, where Tulip tells the player why the Boggart was Merula.

Later, they face the Boggart in Jacob's room for the second time and succeed to making it a clown. They search the room and find a note saying when Vault of Fear was opened before, there were many Boggarts in the Library which means it was nearby. They make the plan to search the entire Library until they find it

Chapter 8: Barnaby Lee
Tulip tells the player they need to gather their friends and search the Library, and she will continue searching Jacob's room. Ben Copper, Bill Weasley, Rowan Khanna and Penny Haywood search the Library with the player and eventually find a note telling them the entrance will be in the Restricted Section, and make a plan to sneak in. The player heads to find Tulip in Jacob's room and finds Merula waiting.

Merula implies she knows why they were searching the Library, and threatens the player. Tulip tells the player she's found nothing when searching Jacob's room but the player finds a note telling them the "book opens the way" and deduces they need to look in Jacob's notebook again. Tulip then tells the player they should bring Barnaby Lee onboard with the plan. The player persuades Barnaby to join the plan.

Chapter 9: The Vault of Fear
Tulip tells the player the plan for breaking in the Restricted Section and think of a way to trick Madam Pince. The player practices spells and then meets Tulip, Rowan and Barnaby at the Library. Rowan tricks Madam Pince and they open the Restricted Section with the Unlocking Charm. Merula shows up and duels the player. When the player wins, Barnaby tells the player to go in the room and he will fend Merula off.

The player, Rowan and Tulip search the room and Barnaby later shows up and tells them Merula left, but she will probably tell a teacher about them. They find the Vault of Fear and enter the room, intending to break the curse and save the school.

They find the Vault of Fear and confront another Boggart which takes the image of Voldemort again, only there are another two Boggarts which take the same form. The Boggarts take the player's there friends captive, and the player saves them with the Boggart-Banishing Spell. The player hears Jacob's voice again telling them to fight, and Boggart Voldemort shows up and duels the player.

When the player wins the duel, they reunite with their friends and open the vault when they made the "ultimate sacrifice" by giving up magic. The player remembers Jacob's broken wand and thought the Vault of Ice opened because he broke his wand. The player brought Jacob's broken wand with them, and it opens the vault. They find a map of the Forbidden Forest and an arrow.

The player takes the map and arrow and heads out of the room and back to the Library before the teachers find them.

Chapter 10: Among Friends
The player meets their friends in the Three Broomsticks Inn to celebrate breaking the curse and drink Butterbeer. Merula told Snape, only there will be no proof of what they have done and Madam Pince will be too proud to admit they tricked her. They wager the next vault will be in the Forbidden Forest.

The player and Rowan then admit to Ben they found letters to him signed by the name "R" in their second year which were addressed to Ben. Ben could not remember them and they worry about the memory loss and whether he's even telling the truth. Bill tells them they should worry about it another day.

Hagrid shows up and implies they were responsible for the fewer Boggarts being found around the school. Dumbledore then shows up and tells Hagrid he was supposed to keep it secret, and the player mentions Dumbledore was missing for the entire year. He says he was looking for people, and he found them. The player was confused and Dumbledore tells them to meet him at the office and he will explain.

The player tells him everything about the day's events, and they deduce that another person keeps tampering with the vaults and opening them. Dumbledore tells them he was looking for the world's finest Curse-Breaker and that he invited her to join them next year. Even though the player broken the rules again, and Dumbledore warns them never to do it again, he rewards them with another chance and one hundred points.

Afraid to Fly
Roughly takes place during Chapter 7, consisting 4 stages: The player agrees and talks to Rowan Khanna who tells the player perhaps they could help Ben Copper improve his Flying class skills. The player finds Ben and helps him study in the Great Hall.
 * 1) Meet Rowan
 * 2) Study with Ben
 * 3) Talk to Ben
 * 4) Attend Flying Class

Ben continued to feel worried about flying which gave the player the idea to help Ben feel okay with flying by using the Levitation Charm on him. They tell Ben to find them in the Courtyard later. They use the Levitation Charm on Ben but he is still nervous about flying so the player agrees to help Ben at Flying class. The player has the choice of how to help Ben and encourage him throughout the class. Ben finds a new-found confidence for flying and thanks the player for their help. Ben tells Madam Hooch and they both receive ten points for their Houses.

Test of Strength
Roughly takes place during Chapter 8, consisting 4 stages: The Prefect also asks the player for a word and tells them they are hoping to continue preparing the player for future challenges by continuing to teach them duelling with Ben. Ben agrees to continue helping the player because it will improve his duelling too. The player decides whether they should learn by having a proper go at duelling each other or whether to go easy on Ben.
 * 1) Report to Angelica/Chester/Jane/Felix
 * 2) Duel Ben
 * 3) Study with Rowan
 * 4) Duel Angelica/Chester/Jane/Felix

They will then duel Ben. Ben will only use the Defence option and the player should use the Sneaky option to defeat him. The Prefect then tells the player to research duelling because they will be duelling the Prefect next. The player and Rowan later meet up to plan the duel they will have with the Prefect. Rowan gathered every dueling book they found and offers to help the player read through them. They then study dueling together. The player then thanks Rowan.

Rowan notices that the player spends little time building friendships with the people in their house, and asks them to spend time with their fellow house friends. The player agrees and then they gather at the Training Grounds to duel the Prefect. The Prefect and the player duel. The player needs to pay attention to the pattern of the Prefect's actions in order to know what to do to defeat them. The player then decides whether they want to tell everyone they won or whether to keep it between them and the Prefect.

The player
The player will receive choices to make throughout the game. The answers they give from a number of three possible answers can determine which wand they receive, how strong their friendship with another character will be or how to deal with a situation which could have an impact on them later in the story. They have the choice of rewards which help contribute to the Courage, Empathy and Knowledge level of the player. The rewards can be earned in classes or by completing pieces of the story. Certain choices may only be available if the player's Courage, Empathy or Knowledge level are high enough.

Energy
The player completes each chapter for both the classes or the story by using energy to complete tasks. The initial full limit of the player's energy is 24, though it can be broadened throughout the game. When the player uses one energy it will take four minutes for the energy to be added back to the game. The number of energy one task will take varies between 1 and 12.

Throughout the game, there are hidden opportunities to gain energy by clicking on a certain character or item. They are known to include:
 * Clicking on the empty portrait placed next to the Charms Classroom so the Girl with Flowers will reappear
 * Clicking on Peeves when he appears between the portrait of Fytherley Undercliffe and the Divination Classroom, so that he laughs and vanishes.
 * This option seemed to only be available after certain events; Peeves used to be a non-interactive element between the Grand Staircase and Courtyard.
 * Clicking on the still-life painting in the West Towers that contains white flowers in what appears to be a tree trunk so that three oranges will reappear and the white flowers bounce.
 * Clicking on the middle of the three suits of armour on the right of the Great Hall entrance when the middle suit is holding a sword and the right suit a shield, so that they will switch what they are holding.
 * Clicking on the unlit torch on the right of the Great Hall entrance so that it will relight.
 * Clicking on the unidentified house-elf near the Hogwarts kitchens when it appears to be asleep so that it will run back to the kitchen.
 * Clicking on the small branch on the path between the Whomping Willow and Hagrid's Hut so that Fang will fetch it and run down to Hagrid's.
 * Clicking on the disorganised books on the bench between the Library and the History of Magic Classroom so that they will be neatly stacked.
 * Clicking on the student with a sled standing in the alley between Three Broomsticks and Honeydukes so that he will slide down.

In-App purchases
The game offers a reward or purchase of coins and diamonds which can be used to buy in-app purchases including more energy or even clothes, hairstyles and accessories for the character. The coins will also need to be used to complete a certain part of the chapter including 100 coins to build a relationship with another character or learning to duel.

At the beginning of Year 1 Chapter 7, a special 48 hour sale is prompted to buy 130 gems for $0.99 (originally $4.99).

House Cup
The player will win or lose House points throughout the game which could depend on their choices. Their ranking will be placed on the Leaderboard for how many points they have earned overall for the House. They will be placed in a list of randomised students and their choices could have an impact on the House placement in the rankings overall. The winner of the House Cup at the end of the year will be rewarded with an increasing number of Gems beginning with 100 Gems for first year and increasing to 125 Gems for second year.

Story, classes, and side quests
The game-playing takes places in two sections: the story and the classes aspect, with the addition of side quests. The player will not need in each chapter to complete a class or a side quest and then move on to the story. They can complete in the order and the pace they decide. However, the game will not allow the player to move on to the next chapter or part of the chapter unless the player completes both the story and class.

To complete a class, the player earns stars within a time limit choice of either 1hr, 3hrs or 8hrs which effect the number of stars they can earn and therefore the rewards. If reaching the maximum 5-star before the class hour is up, the player can leave class early. In each class, they will have to trace spells or rotate potions in an identical way to an old Pottermore feature. The player could be asked a question about the subject during the class, and providing the right answer will reward the player with their choice of energy, points, coins or diamonds. Everyone will receive the same questions but the order in which they are asked throughout each chapter will be randomised. For example, one player could answer the same question earlier in the game than another player who will receive another question instead at that point.

Duelling
When encountering a duel, the game offers three choices: Sneaky, Defensive and Aggressive. Sneaky defeats Defensive, Aggressive defeats Sneaky and Defensive defeats Aggressive. If losing, the player may spend a certain number of coins awarded in the game, and try again.

Friendship
In the App update released on 30 May, 2018, players now are able to build friendship outside of the main story arc.
 * Meal with a Friend: Located at the Great Hall, 10hrs for the next cycle after playing.
 * Play Gobstones: Located at the Courtyard, 16hrs for the next cycle after playing.
 * Drink Butterbeer: Located at the Three Broomsticks, 16hrs for the next cycle after playing.

Behind the scenes

 * It was released on the 24th of April in some countries.
 * While players are only able to interactively participate in Charms, Potions, and Flying during year 1, Transfiguration as an addition in year 2, Herbology as an addition in year 3; the characters of the players are actually attending all canon classes.
 * In Year 1 for example, if the player is in Hufflepuff, Rowan Khanna will mention Herbology and say it would have be more enjoyable were they not having to worry about a murderous plant. It was later brought up in the Side Quests of Chapter 8 in Year 1 in Hufflepuff's house meeting, where they discussed how to help their Head of House, Pomona Sprout, amongst other things. Depending on the players' choice, one conclusion was to help out their Professor clean up after their class.
 * In Year 2 Chapter 5, when visiting Rowan in the Hospital Wing, Jacob's sibling brought their star chart from Astronomy Class.
 * The player may create their own name if they wish, but there are player names which are banned for unknown reasons, including the name Roland. However, should one feel that their names may be mistakenly excluded, the game developer, Jam City, stated that they welcome the feedback so they can take a closer look.
 * Interestingly, the name "Jacob" is not banned, meaning that both the player and his/her brother would share the same name.
 * On the leaderboard, the majority of the names of other students and their appearance are randomised for that player, and the only names which are the same for everyone will be for game-playing characters like Merula Snyde or Ben Copper. The randomised names are similar and can even be the same, with popular surnames being Nguyen, Hernandez, Miller, Young and Carter.
 * The following characters were attending Hogwarts or would have begun attending Hogwarts during the years the player attended from 1984 until 1991. However, they have not been mentioned in relation to the game or are known to appear in the game: Gwenog Jones (graduated 1986 or 1987) Marcus Flint, (Sorted 1986) Penelope Clearwater, Percy Weasley and Oliver Wood (Sorted 1987). Roger Davies, Cedric Diggory, Angelina Johnson, Lee Jordan, Adrian Pucey, Alicia Spinnet, Patricia Stimpson, Kenneth Towler, Fred and George Weasley (Sorted 1989), and Donaghan Tremlett (graduated 1990 or 1991).
 * There were a few other characters from Harry Potter's early years at Hogwarts who would have attended around the same time including Quidditch players and Prefects like Terence Higgs and Robert Hilliard.
 * Based solely on their birth year (though it is not known if they attended Hogwarts), these characters could also have attended Hogwarts during that time: Dunbar Oglethorpe (b. 1968), Myron Wagtail (b. 1970), Kirley Duke (b. 1971), Heathcote Barbary (b. 1974), Herman Wintringham (b. 1974), Stanley Shunpike (b. 1974/1975), Gideon Crumb (b. 1975) and Orsino Thruston (b. 1976).
 * The additional Hogwarts staff from 1984 would have been composed of: Quirinus Quirrell (Muggle Studies, at least in the late 1980s). It is unknown if Bathsheda Babbling already taught Study of Ancient Runes.
 * Even though the Duelling Club has been confirmed to feature in the game, it was originally created by Gilderoy Lockhart in the 1992–1993 school year. It is possible that several different Duelling Clubs were founded and dissolved throughout the history of Hogwarts.
 * In Chapter 1 of Year 2, the player will be told they need to sneak into another House's common room to find an object. The House common room they will sneak into will be different for every House. It could be randomised and ensures the player simply went to another House’s common room. If there's a pattern, it appears Ravenclaw and Slytherin will sneak into the Gryffindor common room, and Hufflepuff and Gryffindor will sneak into the Slytherin common room.
 * During Year 1, Professor Snape is mentioned to be petitioning for the Defence Against the Dark Arts position. The current DADA teacher was having trouble, and the curse on the position is mentioned by Rowan.
 * Within the APK file of the game there exist various images of shapes that correspond to the shapes one must draw in order to cast spells. Many of these shapes are different from the shapes that are used in the final game. For example, a shape like a number four is used to represent Alohomora (similar to Wonderbook: Book of Spells), while the game uses a more circular gesture.
 * In Hogsmeade, some shop names are shortened:
 * Three Broomsticks Inn as simply "Three Broomsticks"
 * Dominic Maestro's Music Shop as simply "Maestro's Music Shop"

Overall

 * The world-class broomstick Firebolt was released in 1993, yet during Flying Classes as early in 1984, Firebolt could be mentioned in a few situations, predating the broom's canon existence by almost a decade:
 * The question "A Firebolt is a type of what?" could be asked.
 * Rolanda Hooch provides a trivia hint, telling the player to familiarise with "Cleansweep, Comet, Nimbus and Firebolt."
 * The question "Which of these is not a broom?" could be asked, Firebolt being one of the choices.
 * The question on who the Divination Professor was could be asked, and one of the options was Professor Umbridge. The player character's wouldn't receive that as an option, because Professor Umbridge worked at the Ministry of Magic and would not become the unlikely Defence Against the Dark Arts Professor until 1995.
 * Though Severus Snape gave a speech about "little foolish wand-waving [in Potions class]" during his introduction for the subject for the 1991–1992 school year, in the game, he clearly used his wand to move phials of ingredients to his potions when he demonstrates. The students, on the other hand, add the same ingredients by hand, though in certain situation, they would cast Lumos in order to properly look through the shelves to search for ingredients.
 * It is possible that Snape did not consider this kind of magic foolish, or he was referring to subjects like Charms, where amateur students wave their wand around without success towards creating the spell. Or, he changed his teaching method at some point before the 1991–1992 school year.
 * At the end of each year in the game, the House Cup is given out to the house with the most House points. While any house can win the cup in all of the years in the game, it is mentioned in PS undefined that Slytherin has won the cup for six straight years, from the 1985–1986 school year to the 1990 to 1991 school year, which take place during Jacob's sibling's second to seventh years. This would also mean that Slytherin didn't win the cup in the 1984–1985 school year, which would take place during Jacob's sibling's first year. However, in the game, Slytherin can win the House Cup in that year.
 * All classes contain students from a specific House instead of having two Houses in a class.
 * All the Slytherin students are in Potions.
 * All the Gryffindor students are in Charms.
 * All the Ravenclaw students are in Transfiguration
 * All the Hufflepuff students are in Herbology.
 * Flying Class is the only exception for there are students from every House.
 * In Potions Class, Jacob's sibling and Merula Snyde appear to share a cauldron. However, they are mentioned to brew potions separately.

Year Two

 * In Chapter 1, Professor McGonagall will say Ben was upset about what happened to him when he was trapped in the cursed ice; this is referring to the arc taking place in Chapter 8 of Year 1, in which the player decides between bringing Penny or Ben to break into the Locked Room alongside Rowan. They will be trapped by the cursed ice and the player saves them. However, if the player had taken Penny instead of Ben, Ben wouldn't have even gone there. Therefore, what McGonagall says makes no sense in this scenario.
 * In Chapter 3, if the player is in Hufflepuff or Gryffindor, they will sneak into the Slytherin Common Room to search for the Black Quill, and eventually be confronted upon leaving, by Felix Rosier, who brought along Severus Snape. However, Gemma Farley, when she became the Prefect to welcome Slytherin first years, informed them that no-one had knowingly snuck into the Slytherin Common Room for more than seven centuries. The game takes place in 1985, and Jacob's sibling was caught sneaking out of the room, contradicting Gemma, unless Snape and Rosier never told anyone.
 * In the beginning of Chapter 5, Rowan is in the Hospital Wing due to being hit by the cursed ice when searching for the Cursed Vaults. Rowan appears in classes during that chapter even when they were supposedly being hospitalised. It is later explained that Pomfrey helped Rowan get to Potions class, even though Jacob's sibling was unaware of this at the time.
 * Rowan attended Flying class immediately following their interaction at the Hospital Wing where Rowan told the player to attend the class alone, since they were not allowed to leave yet and they would send an owl when they were allowed. Rowan then appears in the class anyway.
 * The same kind of thing happens at the beginning of Year 2. Ben Copper immediately went missing at the beginning of the school year when he arrived at the school. If the player's in Gryffindor, they can continue to have interactions with Ben in the common room and throughout side quests even though they are looking for him in the main story.
 * During flying class, an action that requires tapping Penny has the text "LISTEN TO BEN", even if Ben is not seen at all.
 * In Side Quest "Help Hagrid!," when the player helps save Fang from Devil's Snare, Hagrid asks the player what he should name the dog and says he's a new puppy. However, Fang could be found in the game from the beginning in Year 1 which was a year ago by that point in the game. Fang wouldn't be new by then and it makes no sense why Hagrid would wait that long before naming him.
 * In Side Quest "Sleep Walker," the sleep walking girl's appearance and house are inconsistent.
 * In Chapter 9, when Hagrid was relaying how bad the cursed ice had spread throughout the school, Professor Sinistra's surname was misspelled as "Sinestra."
 * Though her surname was spelled correctly in the in-class question "Who is the Astronomy professor?".
 * In Chapter 10, the password Professor McGonagall used to open Dumbledore's office was "Iced Mice," when the correct name of the sweet in question is Ice Mice.
 * Professor McGonagall informs Jacob's sibling that the main reason she found out it was them who got rid of the cursed ice was because of Ben accidentally leaving something behind. This would only make sense if you chose Ben to go with you, otherwise this wouldn’t make sense.

Year Three

 * In Side Quest "Giant Problems," when Fang needed to be found, the player can continue gaining one energy by clicking on the branch on the path to Hagrid's Hut, which makes the missing Fang appear.
 * Jacob's sibling can access Hogsmeade in Chapter 1 if choosing to start the "Giant Problems" Side Quest. However, in Chapter 2, it will appear as if Jacob's sibling had never been to Hogsmeade.
 * In Chapter 2, Jacob's sibling and Hagrid will talk about the Boggart they found. Jacob's sibling will ask Hagrid whether he's begun Defence Against the Dark Arts class yet, which makes no sense because Hagrid no longer attends school. The line was probably intended for Hagrid to say, but the game labelled the speaker as Jacob's sibling ("You") by accident.
 * In Chapter 4, a background character at Zonko's Joke Shop is called "First-Year Boy". First-years and second-years are not allowed to go to Hogsmeade. Though it is possible that he managed to sneak into the village, like Harry Potter did when he didn't get the permission.
 * In Side Quest "Farewell My Prefect," when brewing the Babbling Beverage and choosing to read the instructions, the player mentions Penny being there. Jacob's sibling and the Prefect are the only two in the Potions Classroom at the moment.
 * Mice to Snuffboxes is learned in Transfiguration Class in Year 3. However, during the 1991–1992 school year, Harry and his Transfiguration Class learns this same spell in their first year and even have it on their practical exam.
 * It could be that Professor McGonagall changed the order that she taught certain spells between Jacob's sibling's time at Hogwarts and Harry's time at Hogwarts.
