The first edition deck consists of 84 cards with four types of cards: Keepers, Goals, Actions, and New Rules. While the game begins by requiring players to simply draw and play a specific number of cards, the mechanic mutates when a New Rule card is played. The card may change the number of cards drawn or played per turn, the number of cards held per hand, or the Keepers played. The Goal cards change the Keepers needed to win the game. Games last from 5 to 30 minutes.
