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.
