Crazy Eights

The deal. Each player gets seven cards. The top card of the draw pile flips onto the discard pile to start the game. You play first by default.

Your turn. Play a card from your hand that matches the top of the discard pile by color, by number, or by action-card type (a Skip on a Skip, a Reverse on a Reverse, etc.). Wild cards can be played any time. Click a card to play it; drag to the discard pile for the same effect.

Can't play? Click Draw a card. You draw one card. If it's playable, you may play it on the same turn; otherwise click Pass to end your turn. Turn on force-play in House rules and you'll automatically play a drawn card if it's legal.

Action cards. Skip jumps the next player. Reverse flips direction of play (in a 2-player game it acts as Skip). Draw 2 forces the next player to draw 2 cards and lose their turn. Wild lets you choose the next color. Wild Draw 4 picks the next color and forces the next player to draw 4 and lose their turn.

Stacking. With the default house rule on, a Draw 2 may be answered with another Draw 2 (the count piles up — the player who can't or won't stack draws everything). Wild Draw 4 stacks onto Wild Draw 4 the same way. The two types don't cross-stack.

Last card. When you're about to play your second-to-last card (your hand has two cards), press Last card! before playing. Forget to call and the next player will see your hand drop to one card — you draw two cards as a penalty when their turn starts. The computer always remembers to call.

Winning. First player to empty their hand wins the round. Other players' remaining cards are scored: number cards by their face value, action cards 20 points each, Wilds 50 points each. The points go to the winner. Match length picks how many rounds you play: one round, first to win three, or first to 500 points.

Levels. Easy plays random legal moves. Medium uses simple heuristics — saves Wilds for emergencies, dumps high-value cards first, picks Wild colors based on hand composition. Hard adds card-counting, targets the player with the fewest cards using action cards, and holds Reverse when playing 2-handed.

Wild Draw 4 enforcement. Casual rule: Wild Draw 4 is always legal to play. (Tournament Uno restricts it to cases where you have no card of the current color; this page uses the casual rule.)
