4 Colors - Play Online
Classic card showdown. Digital style. 4 Colors pits you against three computer opponents in a race to zero cards. Match by number. Match by color. Forget to call "Uno"? Pay the price. This is the card game you know, stripped down, sped up, and ready to play anywhere.
How to Play 4 Colors
Your mission is brutal in its simplicity: Empty your hand before the AI does. Each turn, play one card that matches the center pile's color or number. No match? Draw from the deck. First to zero wins. But there's a catch—action cards flip the script fast.
Card Matching & Core Loop
Click the card. Play it. Move on. If your hand shows a Red 7 and the pile shows Red 3, you're good. Same color works. If you've got a Blue 7, same number works. Can't play anything? Hit the deck. Draw one. Try again. The loop is instant: match, discard, repeat. No animations slowing you down.
Action Cards & Chaos
Standard cards won't cut it. Skip cards freeze the next opponent. Reverse cards flip turn order. Wild cards let you choose the new color—crucial when you're holding four greens. Drop a Draw Two and the next player eats penalty cards. Stack them wrong and you'll face the same fate. Action cards aren't optional strategy. They're survival tools.
The Uno Rule (Critical)
One card left? Shout "Uno." Forget it? Penalty hits hard: two extra cards auto-added to your hand. The game enforces this ruthlessly. No mercy. Click the Uno button when you're down to your last card or watch your lead evaporate. Timing this call separates rookies from veterans.
Strategy Against AI
Hold Wild cards until the endgame. Burn action cards early to disrupt opponent momentum. If Player 2 has one card left, hit them with a Skip or Draw Two before they win. Watch the opponent card counts—displayed as stacked decks on screen edges. Three cards? They're close. Seven? They're drowning. Adjust aggression accordingly.
