A desktop patience game played on a 3 x 3 grid in which you have to make 13 from either one or two cards, a King counts as 13 in it's own right, whilst a Queen is counts as 12 so will need an Ace to make 13, A Jack counts as 11, so will need a two to make 13. The first card is laid face up on the first grid, if you cannot make 13 with that card, you then click on the deck and the next card is put in the next grid position, once all the grid positions have been filled and you still cannot make 13 then the game is over, if you can make 13 with either a King on it's own or with the combination of two other cards, just click on the card or cards and if you do have 13 then new cards will be placed on top of those cards.
