Any one card may be placed on the four green circle spaces in the center.
On the ten spaces on the bottom, a card may be played on the next highest card of the same suit. A king, and only a king, can be played to an empty space.
To move a card, click on it to select it, then click on the place where you want the card to go. If the move is illegal, the card won't move. Only one card can be moved at a time.
Click on a selected card to de-select it.
When aces are uncovered, they will be automatically played to the red X spaces. Once an ace has been played to a red X, then the 2 of the same suit can be played on top of it, and so forth. These moves will be made automatically.
The objective of the game is to move all cards to the red X spaces.
