Color Clash.

Each player starts with seven cards. Match the current color, number or action symbol, or use a Wild. You can choose to draw even if you have a playable card. After drawing, only that new card may be played, or you can keep it. No stacking penalties and no jumping in.

Skip misses the next player. Reverse changes direction; with two players it acts as a Skip. Draw Two makes the next player take two cards and miss their turn. Opening action cards also take effect: Skip or Draw Two affects the first player, Reverse starts with the dealer in the opposite direction, and an opening Wild lets the first player choose the color.

A Wild +4 is legal only if you have no card of the current color. A matching number or action in another color is fine. You may risk an illegal play, but the next player can challenge: if you held the current color, you draw four and they keep their turn. If you were legal, they draw six and lose their turn. Accepting means drawing four and losing a turn. A challenge reveals the offender's remaining cards.

With two cards, press Last card! before playing one. If you forget, you can still call before another player catches you. A catch costs two cards. The catch window closes when the next player plays, draws, or resolves a challenge. Computer players can forget too: use Catch missed call before they continue.

Empty your hand to win a round. Remaining number cards score face value; Skip, Reverse and Draw Two score 20; Wild cards score 50. Final draw penalties are applied before scoring. First to 500 wins the match. Scores reset on refresh. This game uses the classic 108-card set, with original artwork and no special expansion cards.
