Room Synthesis Screen. Cards shown areMoment's Reprieve andKey of Beginnings.

Map cards (マップカード, Mappu Kādo^?) appear inKingdom Hearts Chain of Memories as a type ofcard which allowsSora andRiku to bring form toCastle Oblivion's rooms through Room Synthesis. Like battle cards, they are randomly numbered 0-9. Map cards are generated at the end of battles, aside from boss battles. Sora and Riku can hold up to 99 map cards at a time with the exception of Keycards, and cannot delete any map card if they have 20 or less left. Each world has its own designated layout for each map card, which will remain unchanged if the same map card is used again.

Map cards are divided into "red map cards", which modify the behavior of theHeartless within the room, "green map cards", which modify the status of the protagonist or the Heartless in the protagonist's favor, "blue map cards", which providetreasure chests,shops, orsave points, and golden "Keycards", which progress the story or provide a chest with a unique reward. InKingdom Hearts Re:Chain of Memories, these types are signified with an "R", "G", "B", and "!", respectively. At the beginning of bothSora's Story andReverse/Rebirth, Sora and Riku will both start out with a Moment's Reprieve card that is labeled 1, which Sora is required to use first as part of the tutorial.

Unlike Sora, as Riku's gameplay lacks several features he cannot obtain as many types of the regular map cards as Sora can. However, as Riku obtains a lesser amount of these types, Riku can freely obtain any of them regardless of floor, with the lone exception of Moment's Reprieve in Hollow Bastion, while for Sora, the world he is in affects what kind of map cards he may obtain as well as their rates.

InKingdom Hearts Re:Chain of Memories, the difficulty level affects the ratio of Sora or Riku obtaining a Random Joker card as long as the player's standard Map card set is not maxed out.

100 Acre Wood is the only world that does not use Room Synthesis.

Room Synthesis[edit]

WhenRoom Synthesis is activated, a set of card outlines will appear on the screen with various colors, numbers, and symbols. These represent the criterion for opening the door and creating a room.

• If an outline is red, green, or blue, then it can only be opened with a Map Card of the same color. If an outline is white, then any color of Map Card can be used.
• If an outline has a number with a symbol on it, specifically ↑, ↓, or =, it can only be opened with a Map Card that has a higher, lower, or equal number on it. Map Cards with "0" on them can satisfy any ↑ or ↓ requirement.
• If an outline has a number without a symbol, then it must be satisfied by applying multiple Map Cards whose points sum is equal to or greater than the listed number.
• If an image of a yellow card appears in place of an outline, then that indicates a specific keycard that must be used.
• A "Random Joker" card is able to satisfy any set of requirements, except for a keycard requirement.

In normal rooms, all the doors leading out of that room contain the next-highest number from the number value of the card used to create that room. For example, a room created with a "3" card will have outward-leading doors that require at least a "4" card.

• If the room was created with a "9" card, then the doors will require a "0" card and will not accept any other number value.
• If the room was created with a Random Joker card, then the card values for the doors will be random.
• Doorways leading into the special rooms are not affected by this system (excluding Unknown Room and Conqueror's Respite).
• Doorways leading out of the special rooms will initially assume the room was created with a "0" card, meaning the outward doors require at least a "1" card.

At any time, an already-opened room can be remade by interacting with any of the door frames used to enter it. The cost-ramping rules as listed above will still apply, using the cost of the room Sora is standing in as a base.

If Sora or Riku leaves a floor, then all rooms opened on that floor will be reset. Specifically, the floor's first room will reset to Unknown Room, the last room will reset to Conqueror's Respite, and all other rooms will become closed.

Rooms created without cards[edit]

Special Rooms[edit]

Unknown Room[edit]

The Unknown Room is an automatically created room. It is the first room in every world visited, and resembles the Feeble Darkness room, albeit slightly bigger. It is also possible that an Unknown Room is created after Sora is deposited in a room that is not already opened after entering an event room such as the Room of Beginnings. InKingdom Hearts Chain of Memories, this room is the same as other Unknown Rooms, but inKingdom Hearts Re:Chain of Memories, this Unknown Room will have the properties of the first Map Card used to open the event room. In Castle Oblivion, the room of the first battle againstMarluxia is an Unknown Room. InKingdom Hearts Re:Chain of Memories, it contains aSave Point, and serves as the room in which Sora is deposited after saving once the game is cleared.

Room of Beginnings[edit]

The Room of Beginnings is the first story room that can be accessed in a world, and it is usually used to introduce the main characters of that world, though it can also contain an event or even a boss battle. After the room's completion, it is sealed, and the hero is given another keycard. Its card is emblazoned with the Keyblade symbol on a purple^{[KH CoM]} or blue^{[KH Re:CoM]} background. InKingdom Hearts Re:Chain of Memories, Riku's Room of Beginnings in Destiny Islands contains two boss battles, and he can choose to leave the room and save between fighting the two battles.

Room of Guidance[edit]

The Room of Guidance is the second story room that can be accessed in a world, and it is used to set up the climax of the world's story and lead into the final battle. After the room's completion, it is sealed, and the hero is given a Key to Truth keycard. Its card is emblazoned with the Heart symbol on a blue background.Destiny Islands andMonstro are the only worlds in which Sora faces the boss of the world in the Room of Guidance.

Room of Truth[edit]

The Room of Truth is the final story room that can be accessed in a world, and it contains the battle against the world's main villain. After the room's completion, it is sealed, and the hero is transported to the world's exit, a Conqueror's Respite room. Its card is emblazoned with the Heartless emblem on a blue background.Hollow Bastion (or the 12th basement) is the only world in which the Room of Truth exists in Reverse/Rebirth.

Room of Rewards[edit]

TheRoom of Rewards (未知なる宝の部屋, Michinaru Takara no Heya^?, lit. "Room of Unknown Treasure"), called theHidden Chamber (隠し部屋, Kakushi Heya^?) inKingdom Hearts Chain of Memories, is a special room that can be opened once per world. The room contains a treasure chest with a specific card orsleight. InKingdom Hearts Re:Chain of Memories, a Room of Rewards starts off with a single reward, but when certain conditions are fulfilled, it will also contain a second treasure chest with an additional reward:

• Japanese PlayStation 2 release: Have a completedKingdom Hearts II Final Mix save file on the memory card.
• North American PlayStation 2 release: Complete "Sora's Story" and "Reverse/Rebirth"
• Kingdom Hearts HD 1.5 ReMIX re-release: CompleteKingdom Hearts 358/2 Days. This requires viewing all cutscenes, as well as all journal-based entries: Roxas's Diary, Secret Reports, and Character Files. In the PS3 release, the obtention of the 358/2 Days Master trophy informs about the completion.

If the requirement for the second chest has been fulfilled, then the Room of Rewards will contain both chests. Once both treasure chests have been emptied, the Room of Rewards for that world is no longer accessible.

If the requirement for the second chest hasnot been fulfilled, then the Room of Rewards will only contain the first chest. In this case, once the second chest's requirement is met, a second Key to Rewards can be used to open the room a second time.

Sora can only carry one Key to Rewards card at a time.

Conqueror's Respite[edit]

The Conqueror's Respite is a tall room that is only accessible after completing the last available key room (excluding Room of Rewards) found in most worlds. It contains a Save Point and the world's exit on its highest platform, and usually has a tall ladder from the entrance to the highest platform. There are never any Heartless in this room. In Sora's Story, with the exception of Castle Oblivion, Sora is directly transported to the room after completing the final story-based area but in Reverse/Rebirth, Riku is merely put back in the room he was just in, and he must make his way to the exit on his own. InKingdom Hearts Chain of Memories, Riku must create the last room of each world, while in the remake, the Conqueror's Respite is, with no need to create it, made accessible as soon as he creates the room with the door leading to it. After the first time through a world, the Conqueror's Respite is only accessible if the level is entered from the exit hall of the floor, like the Unknown Room. As there is no Conqueror's Respite room in Castle Oblivion, in Sora's Story, the Unknown Room is used in its place.

Obtainment Rates[edit]

Refer to the articles of each Heartless for information about the drop rates of theirEnemy Cards.
