📋 Sommaire
Slapjack is a fast-paced and entertaining card game primarily played by children, although it can be enjoyed by players of all ages. The game requires a standard 52-card deck and can be played by any reasonable number of players from 2 upwards, with 4 to 10 being the ideal number.
It is worth clearing up one common confusion straight away. Slapjack and Irish Snap are two different slapping games, not two names for the same thing. In Slapjack only jacks are slapped, the first slapper collects the cards, and the aim is to collect cards. In Irish Snap, cards are slapped when they match a called value, the slowest slapper collects the cards, and the aim is to get rid of cards.
Objective
The objective in Slapjack is to collect all the cards, which means winning the centre pile every time a jack is turned up and avoiding the penalties that come with slapping the wrong card.
Setup
To set up the game, divide the deck of cards roughly equally among the players. Each player then holds their cards as a face-down pile. The game proceeds clockwise, with each player turning over the top card of their pile and placing it face-up in the center of the table, creating a face-up pile.
How to Play
When someone plays a Jack, the first player to slap it—that is, put their hand palm down on top of the center pile—wins the center pile and adds these cards face down to the bottom of their own pile. Play then continues, starting with the player to the left of the one who won the cards.
When playing a card, you must not peek at it in advance; you must turn it over so that everyone sees it at once. It is best if the card is moved to the center of the table face down and then turned "away from" the player (so that if anything, the others will see it a split second before the player).
If several players slap simultaneously, the person whose hand is underneath (i.e., in contact with the card) is the winner of the cards. A referee might be needed if you are very competitive about this.
If a player slaps a card that is not a Jack, the player who slapped has to give the top card of their own pile face down to the person who played the card that they wrongly slapped. That person adds it to the bottom of their own pile.
If you run out of cards, you no longer play a card when it is your turn. You are still entitled to take part in the slapping of the next Jack, and if you win, you are back in the game. If someone else wins, or if you meanwhile slap a card that is not a Jack, you are out of the game.
Scoring and End of Game
When one player has all the cards, that player wins. If you wish, you can play with a time limit, and if no one collects all the cards before then, the person holding the most cards when the time limit is reached is the winner.
Common Variants
The closest relative is Irish Snap, a British game best for 4 to 8 players in which the aim is to lose all your cards. The whole pack is dealt out face down and players are not allowed to look at their cards. The dealer plays their top card to the centre, revealing it as they put it down, and shouts "Ace". The next player plays and shouts "Two", the next "Three", and so on through Ten, Jack, Queen, King, then back to "Ace". Whenever the card played matches the value being shouted, everyone must slap the pile: the last hand down, the one on top, picks up the whole heap and adds it face down to the bottom of their pile. Play restarts from "Ace" with the player to the left of whoever picked up. Slapping when the card and the call do not match carries the same penalty, the entire heap. The game runs until only one person still has cards to play, and that player is the loser.
Irish Snap itself has a variation where the aim is to find a winner rather than a loser. To win, you have to play all your cards and then slap the pile one more time at the next legal opportunity. If, having run out of cards, you are the last to slap, or if you slap when you should not, you have to pick up the pile as usual, and the game continues.
Why This Game Is So Popular
Slapjack's popularity stems from its simplicity, speed, and excitement. The thrill of slapping the cards, the anticipation of drawing a Jack, and the competitive spirit make it an addictive and memorable game. A memorable moment during play could be when a player successfully slaps a Jack, causing a frenzy as other players rush to claim the cards.
