Play Solitaire with number cards keeping the running total between zero and 21. Clear the board on each level to complete it and win diamonds. You can use diamonds earned to place cards in the trash. You can also place a card in the HOLD spot to play later. Use this spot Strategically to help keep from going over twenty or below one.
Click on a card to remove it from the board. A removed card will have its number added to or subtracted from the running total. Don't let the running total go below one or above twenty.
