The goal of uno is to get rid of all of your cards first. However, you can only cards of the same color or value unless its wild. Other cards, such as, skip, reverse, and draw two add some variety to the game. When draw one is green you can play. If you can't play a card you must draw one. If you can't play the card you draw, then you must click the green pass button to forfet your turn Click your cards to use them. Click the arrows above the cards to move them from side to side if you have can't see all of your cards. No known glitches. If one is found please report it so I may quickly fix it.
