Quick Instructions

Staying true to the original rules and deck composition of 108 cards, Four Colors brings the fun and competitive spirit of UNO into the digital world.

  1. Each player is dealt 7 cards to start and the rest are placed face-down in a draw pile. The top card of the draw pile is flipped to begin the discard pile.
  2. On your turn, you must play a card that matches the top card on the discard pile either by color, number, or symbol.
  3. If you don’t have a match, you must draw a card from the draw pile until you get a playable card.
  4. Play continues clockwise until one player has no cards left, then they win.
  5. You must press the 4 colors “1” button in the middle when you have only one card left or you’ll be penalized with 2 extra cards.

Some cards have a special effect. Each card also has a point value that is used for scoring at the end of the game.
