fan tan, card game for three to eight players using a regular deck. All cards are dealt after each player antes (pays) one chip into a pool. Play rotates to the left and if a player cannot play a card he must ante into the pool. Sevens must be played first. These are set (or foundation) cards, and sequences up to the king or down to the ace are formed. Play ends when any player gets rid of the last card in his hand.
