Shuffle the cards and deal them out equally. Each player puts their cards face down in front of them in a pile. In turn, each player turns up their top card and places it in front of their own pile. When any turned up card matches a top card on any other pile, the player who calls "SNAP" first wins both matching piles. They are placed down under their own pile. If a player calls "SNAP" by mistake or two players call "SNAP" together, their piles are placed face up in the middle to form a pool which acts as another pile from which players can call "SNAP". Once a player has turned over their last card and lost their pile, they are out of the game. The game continues until there is one player left holding all the cards. They are the winner!
