Try to get rid of all your cards before the computer does. Drag one card at a time from your hand at the bottom of the screen to one of the four discard piles in the middle of the screen. If the arrow under the deck is pointing up, place a card that is one value higher on top. If the arrow is pointing down, place a card that is one value lower on top. Going up, once you get to 13 the next match is 1. Going down from 1 the next match is 13.

Special Cards:
Wild Cards can be placed on an card and any card can be placed on top of them.
Red cards with the circular arrow on them will reverse the direction of the deck.
Lightning cards will score you a bonus if you place them on top of other lightning cards.

If the computer gets stuck, the "flip it" card will appear. Click it to put new cards on the four discard piles.
