Pyramid Solitaire Silver
You can play with any fully open card. If a part of the card is covered by another card of the pyramid, you can play this card only when this card is removed. A player can remove a card only if he finds another card that suits it so the sum of their values would be 13. The goal of the Pyramid Solitaire Silver game is to remove all cards from the pyramid. Any card turned face down can be selected along with a card from the pyramid to add up to 13.
