Pyramid (solitaire)

To play, pairs of uncovered cards can be removed to the foundation if their values total 13.

If no match is made, the drawn stock card is played into a waste pile.

(A variation, Par Pyramid, allows the waste to be turned over and dealt as a new stock twice.)

A variation of the game was released on the Microsoft Entertainment Pack 2 in 1991, under the name Tut's Tomb.

When the game is played through Microsoft Solitaire Collection, the cards in the Stock are face-up rather than face-down.
