Slapjack is the fast card game where the quickest hand wins, and on My MP Games you can play slapjack online free in seconds. The deck is split between two players, you take turns flipping cards onto a pile, and the moment a Jack appears the first player to slap it takes the whole pile. Slap the wrong card and it costs you. Play a friend with a room code, share one phone or keyboard for a local game, or test your reflexes against a computer with three speed levels. It runs in the browser on phone, tablet and desktop with no download and no sign-up.
How to Play Slapjack Online
Each match uses a full 52-card deck. Here is how a game runs on this page.
- Pick a mode. Press Play vs Computer for an instant match, Create room to play slap jack online with a friend, Join room if you have a code, or Local vs to play on one device.
- Get your stack. The cards are shuffled and dealt face down, 26 to each player. Your card count is shown next to your stack.
- Flip in turn. When it is your turn, press Flip or the space bar to turn your top card onto the pile in the middle.
- Slap the Jack. When a Jack lands, the table lights up. Hit SLAP, or press S or J, before your opponent does. The first slap wins every card in the pile.
- Keep going. The player who wins the pile flips next. Play on until one player holds all 52 cards, or until someone wins the number of piles picked for a short game.
Slapjack Rules
Flipping
Players flip one card at a time, taking turns. You flip away from yourself so both players see the card at the same moment. On this page the card appears on both screens at once, so neither player gets an early look.
Slapping
Only a Jack may be slapped. The server records whose slap arrived first, so ties are settled fairly even in an online slapjack game. The winner adds the pile to the bottom of their stack.
False slaps
If you slap any card that is not a Jack, you pay one card from your stack to your opponent. Queens and Kings are the usual traps, because the picture cards look alike at speed.
Running out of cards
A player with no cards left is not out yet. Their opponent keeps flipping, and if the empty-handed player is first to slap the next Jack, they take the pile and are back in the game. If the opponent slaps that Jack first, the game is over. A false slap with no cards to pay also ends the game.
Short games
The classic game can run a few minutes. The host can switch to first to three or first to five piles for a quick match.
Game Modes: Online, Local and vs Computer
Slapjack online with friends
Create a room and share the code or invite link. Each player plays on their own screen, and the server decides who slapped first.
Two players on one device
In Local mode, both players share a screen. On a keyboard, A slaps for Player 1, L slaps for Player 2 and the space bar flips. On a phone or tablet, each player gets a big slap button on their side.
Play vs Computer
Choose easy, medium or hard. The easy computer takes over a second to react and sometimes slaps a Queen or King by mistake. The hard computer reacts in about four tenths of a second, which is quick even for practised players.
Slapjack Tips
- Watch the pile, not the button. Rest your finger on SLAP and keep your eyes on the middle of the table.
- Look for the J. Train yourself to react to the letter J in the corner rather than to any picture card.
- Stay sharp on your own flip. Players often relax while they flip, and a Jack from their own hand catches them out.
- Do not panic when low. With a few cards left, a single Jack can turn the game around.
History of Slapjack
Slapjack is a traditional family card game, played in homes and schools for generations as a first card game for children. It needs only a standard deck and teaches card ranks while rewarding quick reactions. Egyptian Ratscrew is a more complex version with extra slap rules and face-card challenges.
