They have to play two cards each time, one on each side of the Jin-Jang card following the rules, which by default require higher number on the Jin side and lower on the Jang side in the same color. (Alternatively, a player can place the same number in any color.)
Also, the players are aided in their success by several characters, who require payment (money).
The game ends when everyone has only two cards left in their hand.
The player who earns the fewest points wins the favor of the goddess and glory will be theirs until next spring.
