Be warned: victories in Pyramid are an elusive phenomena. Very rarely will you be delt a hand that can be won, and if you are making poor choices will lose the game. Some people will surrender to frustration and never win Pyramid.   

Rules   
Cards are removed in twos, must total 13, and may only be played if they are not covered by another card. Numbered cards are worth their face value, Jacks are 11, Queens are 12, Kings are 13, and Aces are 1. To remove cards, tap one card to select it. Then, tap a second, eligible card. If the combined value of the cards is 13, then both cards are removed. Kings are a special case. Since they are worth 13 points, they are removed from the deck by themselves.   
     You may play any combination of cards form the pyramid and from the deck. Tap the deck to turn a card. This card forms the top of the discard pile. If you play it, the card will be removed from play along with its mate. If you flip another card it remains. If the top two cards of the discard deck total 13 you may opt to remove them by double tapping of the top card.   

Scoring   
In Pyramid, you receive 25 points for every time you remove a card or cards whose value adds up to 13.
