All cards are laid face up and must overlap each other. The pyramid has seven rows, starting with one card on the top and ending with seven cards on the bottom. The Pyramid Solitaire game uses a standard deck of 52 cards and owes its name to the 28 cards that appear on the tableau in the form of a pyramid (see figure 1). The game is played by one person, and the basic rules are fairly simple. The goal is to remove pairs of cards that add up to a total of 13. Pyramid is a unique twist on the classic Klondike Solitaire game, where strategy and fun are combined with a mild mathematical challenge.
