Open as many safes as possible in the Club Unlock card game
The players, embodying thieves, begin the game empty-handed. Each turn, a player can either draw a key card (keys come in four colors), or play one or more combinations of four key cards of the appropriate color to open some of the 35 available chests (only seven chests and their contents are revealed and accessible each round) in order to collect money.

Players receive a bonus for opening the seventh and final chest of each round, as well as for opening two or more chests in a single turn. When all 35 chests (five rounds) have been opened, the player with the most money wins the game.
