One of the many International Brands found at The Real Beer Page. Anyway, a good game with a very high buzz factor. The dealer begins by placing cards, face up, in a stack, and calls out the number on each turn.
Rounds end when the dealer runs out of cards.
Some people try to add some more fun to the game by requiring that all players have the 'snap hand' behind their backs. Others call snap on two face cards of same suit in a row, or cards in either ascending or descending order.
