Use a standard 52-card deck
Shuffle the deck thoroughly
Deal all cards evenly to all players face down
Keep your cards in a face-down pile
Take turns in order, or play simultaneously if agreed
On your turn, flip the top card of your pile face up into the center
Continue placing cards into a central pile one at a time
Watch for a Jack to appear on top of the center pile
When a Jack appears, slap the center pile as fast as possible
The first player to slap the Jack wins the center pile
The winner takes all cards in the center pile and adds them to the bottom of their pile
If a player slaps when there is no Jack on top, give that player a penalty if using one
Keep playing until one player has all the cards
The player with all the cards wins the game
