Pyramid Solitaire is a game that requires luck and quick thinking to match pairs of cards that add up to 13.
The objective is to pair up all the cards in the deck. The pair is two cards whose ranks total to 13.
This is a classic addition (sum 13) solitaire game, in which the layout of the cards is reminiscent of the ancient pyramids of Egypt. Other variations of this game are Giza Solitaire and Pharaohs Solitaire.
Other games that resemble a pyramid structure are Elevator Solitaire (inverted pyramid) and Tri Peaks Solitaire (three small pyramids side by side). If you like the idea of forming pairs, we recommend Isabel Solitaire.
