28 cards are dealt face up to form a pyramid, the rest of the 52-card deck is placed at the side (the stock). Remove pairs of exposed cards from the foundation of the pyramid whose values add up to 13. Aces value at 1, Jacks at 11, Queens at 12. Kings value at 13 and can be played individually. You can draw cards from the stock to match them with any exposed card. You win when all cards of the pyramid got paired and removed from the table. The faster you pair the cards, the higher the score!
