Harry Potter: Hogwarts Mystery

Harry Potter: Hogwarts Mystery is a video game developed by Jam City, part of their Portkey Games label, that was released for mobile devices on 25 April 2018.

In this game, the player creates their own character, and takes on the role of a Hogwarts student. The character experiences all seven years, and takes part in classes as well as extra activities such as the Duelling Club.

Several actors voiced characters that they had played in the Harry Potter films before, including Warwick Davis, Michael Gambon, Maggie Smith, Gemma Jones, Zoë Wanamaker and Sally Mortemore.

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. The player agrees and talks to Rowan who tells the player perhaps they could help Ben improve his Flying class skills. The player finds Ben and helps him study in the Great Hall.

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.

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.

Side Quests
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.

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 Ground 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 gathers with people in their house, including Rowan and the Prefect to talk about and revise for their classes. The player has the option of being part of planning for revision or to go along with the other's plans.

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 gcuarding 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. Penny reveals she made the Strengthening Potion and drinks it. She then broke the ice. 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. 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.

Chapter 10: Year's End
The player attends the End-of-Term Feast where they find out 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 tells the player she will continue trying to find the Cursed Vaults. Rowan 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 Staircase 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 and Ben and ask them to help search for them. They hear 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 Staircase 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 location of which will be different for every House), 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 even though they are 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 Gryffindor Common Room using the Shrinking Charm and then the Growing Charm. Rowan warns the player the Gryffindor Prefect will be very smart and might think Slytherin will sabotage the entrance 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 Prefect of the House you are sneaking into appears and there's an opportunity to trick them. The player decides what to do. They learn Reducio and have the chance to tell 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 the plan and Ben will be fine.

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 untransifgure 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
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 5.

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 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

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.

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.

Classes and story
The game-playing takes places in two sections: the story and the classes aspect. The player will not need in each chapter to complete a class and then move on to the story. They can complete both in the order they decide 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. 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.

Duelling
When encountering a duel, the game offers three choices: Sneaky, Defensive and Aggressive. Sneaky defeats Defensive, Aggressive defeats Sneaky and Defensive defeats Aggressive.

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.
 * Unconfirmed if players would all get this specific situation; as a Hufflepuff, Rowan Khanna expressed more than once that Herbology would have been more enjoyable if not having to worry about a murderous plant. This later was 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.
 * 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.
 * The player will be asked to answer a question during the classes. Everyone will receive the same question 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.
 * 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), and Sybill Trelawney (Divination). 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. Ravenclaw will sneak into the Gryffindor common room, and Hufflepuff will sneak into the Slytherin common room. It's unknown which one out of Ravenclaw and Hufflepuff that Gryffindor and Slytherin will sneak into.

Mistakes

 * The world-class broomstick Firebolt was released in 1993, yet during the Flying Class in 1984 a question along the lines of "what is a Firebolt" could be asked, predating the broom's canon existence. The said question can be asked at different chapters in the story depending on the player.
 * Another asks the player who the Divination Professor was 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. 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.
 * In Chapter 8 of Year 1, the player decides whether to bring Penny or Ben to break into the Locked Room with them and Rowan. They will be trapped by the Cursed Ice and the player saves them. However in Chapter 1 of Year 2, Professor McGonagall will say Ben was upset about what happened to him when he was trapped in the Cursed Ice. If the player had taken Penny instead of Ben, he wouldn't have even went there. Therefore, what McGonagall says makes no sense.
