Pyramid Solitaire is a card game played with a standard deck of 52 cards. The objective is to remove all cards from a pyramid-shaped layout by pairing cards that add up to 13. The pyramid consists of 28 cards arranged in a triangular formation, with the remaining cards forming a draw pile. Players can only remove cards that are not covered by other cards. The values of the cards are as follows: Kings are worth 13, Queens 12, Jacks 11, and numbered cards retain their face value. Aces are worth 1. The game ends when all cards are removed or no more moves are possible.
