About this game
4 Colors is a hand-clearing card game against up to three computer opponents. Play cards that match the current color or number and use action cards as opportunities arise. The goal is to be the first player with no cards left. Because the playable color or number can change with each turn, a card that looks useful now may serve a different purpose later. Pay special attention as your hand becomes small: the game's Uno button is part of finishing correctly, with a penalty for forgetting it.
How to play
Click or tap a card that matches the color or number in play. If you cannot make a matching play, select the deck to draw. Read the action cards and consider their effect before choosing among your available cards. When only one card remains in your hand, click Uno. Missing that declaration adds two cards as a penalty. Continue matching and playing until you empty your hand.
