Play the solitaire card game in its pyramid version. Remove all cards from the pyramid to win the game. Cards must be selected in pairs to be removed. Their sum must correspond to the value 13. Thus Aces have a value at 1, Jacks at 11, Queens at 12 and Kings at 13. When you cannot continue, you have a draw pile at your disposal. There is also a help button, which you can use only to a limited extent. The quicker you match the cards, the higher your score will be. Enjoy!
