Current win streak: 0
Match the top card on the discard pile by color, number, or symbol — or play a Wild. First player to empty their hand wins the round.
When a play leaves you with exactly one card, call “Four!” before the next player acts. Forget, and you draw 2 penalty cards. Tap the red FOUR! button, press F, or hit Y / Triangle on a controller. You can also tap it while you still hold 2 cards to arm it for the card you're about to play.
Plug in an Xbox or PlayStation controller and play the whole game from the couch: D-pad or left stick moves, A / Cross plays a card, X / Square draws, Y / Triangle calls “Four!”, and B / Circle goes back. Keyboard works too — arrow keys, Enter, D to draw, F for “Four!”.
Create a room and share the 4-letter code. Friends join from their own devices — no account needed. The host starts the game once 2–4 players are in.
