The dealer deals seven cards to everyone and puts the rest in a pile facedown. The top card should be turned face up in a separate pile to start the discard pile. If the top card in the discard pile is an eight it should be returned to the deck and a new top card chosen. The player to the left of the dealer begins by discarding one of his/her cards if it matches the suit or rank of the top card in the pile. For example, if the top card is a 7 of clubs, the person could discard any 7 (hearts, spades or diamonds) or any club. If they don't have a matching card they must draw from the pile until he/she gets one that is playable.
Players keep playing this way around the circle. Eights of any suit are wild cards and can be played down on any card. The player who plays an eight gets to choose the suit the next player plays next. Players can pick up cards from the deck even if they have playable cards. Sometimes this is a useful strategy to change suits and keep other opponents from winning.
