The object of the game is to remove pairs of cards that add up to the total of 13 from an arrangement of cards - a pyramid of 28 cards (kings are discarded as single card). Only cards that are exposed (i.e. no other cards are overlapping them) can be discarded. The draw pile is composed of 24 cards that can be exposed (one at a time) in the discard pile by clicking on the draw pile. The cards to be discarded can be both in the pyramid or one card in the pyramid and the exposed card in the discard pile.
Select a card by clicking on it. Unselect it by clicking on it again.
Aces are worth 1; Jacks are worth 11, Queens are worth 12. Kings are worth 13 and can be discarded as a single card.The combinations which can be discarded are:
King – as a single card
Queen + Ace
Jack + 2
10 + 3
9 + 4
8 + 5
7 + 6
The score is defined as follows:
