| Uno is a card game played with a specially printed deck. The custom deck consists of cards of 4 colors: red, green, blue, and yellow. The ranks in each color are 0-9. To start the game, seven cards are dealt to each player, and the top card of the stock is exposed to start the discard pile. At each turn, a player may play a card from their hand that matches the color or rank of the top exposed card, or play a wild or wild draw four. |
