This is a solitaire where cards are placed in the shape of a pyramid while each card except those from the bottom line is blocked by 2 other cards from the line below. You can only use the unblocked cards from the pyramid and from the 3 slots at the bottom. You must search for pairs of cards that make 13 points together. cards from 2 to 10 have the corresponding points value. Jack, Queen and King have 11, 12 and 13 points and Ace has 1 point. If you don't have any options you can open the next 3 cards from the deck or place one of the unblocked cards to the spare card slot. This slot is very useful, but you must remember that it can only contain 1 card and you won't be able to use it again until you clear the card it has.
