First of all, although UNO can be played using a regular deck of playing cards, it is easier to use the deck of cards made especially for the game. The cards are readily available in Japan and come with instructions in Japanese. The basic aim of the game is to get rid of all of your cards by discarding cards which match the color and/or number of the top card in the discard pile. If you cannot discard, you must pick up a card from the stockpile and wait until it is your turn again. The first person to get rid of all of his or her cards (without forgetting to say "uno!" when down to only one card) is the winner.
