A standard deck of cards (no Jokers)
2 to 8 players
How to play Slapjack
Deal the cards as evenly as possible. Without looking, players take the cards in their hand and form them into a neat pile facedown.
Starting with the player to the left of the dealer, each player quickly places the top card from his stack onto the middle of the table. Cards will start to stack up there. The middle cards don’t need to be neatly stacked. It is more important that the game moves quickly from player to player. Players continue to play cards and keep a watchful eye on the middle stack. When a Jack is played, the first player to slap the card wins the entire pile.
Players who have no more cards left to play (or players late joining the game) may try to slap their way back in. If they slap a Jack first, they collect the pile and start playing again. If a player incorrectly slaps the pile when it is not a Jack, he must pay a penalty card, facedown, to the player who played the card.
The person who collects all the cards wins the game. If the game is taking too long, you can set a time limit and count cards to determine a winner when time expires.
Make it more fun
If this game seems too simple or the players start losing interest, throw in some challenges. One popular variation is to have each player “count” as he plays a card. The first player says “Ace,” the next says “two,” and so on up to “King.” If the card played matches what the player said, then the first person to slap wins the pile.
