Map Cards are cards used to open the rooms contained within the various worlds in Kingdom Hearts: Chain of Memories.
There are five varieties of Map Cards and each type of Map Card synthesizes/creates a different type of room. Additionally, each card that is received is randomly numbered from 0 to 9. To open a door to a room, Map Cards must be matched to the number on the door and/or meet other special card requirements as stated by the door. Like all other 0 cards that can be used in the game, 0 value Map Cards function as 'break' cards, meaning that if no other card of a required value is available in the stockpile, a 0 numbered Map Card can be used to 'break' the door, which consequently resets the counter to start back at 1 for all following doors.

Room of Rewards
The Room of Rewards in each world contains a treasure chest with a specific card or sleight the first time it is opened. A Room of Rewards starts off with a reward from set 1, and if you have a completed Sora's Story save file on your memory card, it will also contain a second treasure chest with a reward from set 2. Once the world's unique treasure has been obtained, a Room of Rewards will operate like a Calm Bounty room.
