Persona 4
Shuffle Time carries different Personae for every individual dungeon in the Midnight Channel. Unlike Persona 3, there are no Minor Arcana cards - the reward of a Shuffle Time is solely a Persona.

There are three types of Cards in Shuffle Time:
 * Persona card. Personae that are already in the player's possession are not generated.
 * Blank card; symbolized by a gray glass shatter effect. Nothing happens when this card is selected.
 * Penalty card; symbolized by a red and black diagonal cross. Players will not receive EXP, money and items after battle.

There are also three different Shuffle methods:
 * Rotating cards either horizontally, diagonally or a combination of both.
 * Memory match, where players match two cards. Has at most five attempts.
 * Similar to slot machines, players match three same cards either horizontally or diagonally upwards/downwards.

There is also a random chance that a player, after managing to obtain either a Persona card or a blank card, is granted an Arcana Chance.
