The object of the game is to remove all 52 cards in the deck by discarding pairs of cards that total 13. Kings count as 13 and may be removed just by clicking on them, Queens are 12, Jacks are 11 and all other cards count as their face value, with the Ace counting as 1. Only cards that are completely uncovered are available for play. At the start of the game, 10 cards are dealt from the deck, each in it's own stack, called the tableau. The remaining cards are placed facedown and are called the stock pile. You start by matching the cards in the tableau that total 13 by clicking and dragging them over each other. All cards that total 13 are removed from the tableau into the discard pile on the lower left of the screen and are no longer available for play. Once all possible pairs of 13 have been removed from the tableau, you click on the stock pile and 10 more cards are dealt into the tableau. You continue this sequence of play until all the cards from the stock pile have been dealt and/or you clear all 52 cards by pairing them up to win the game. You receive 1 point for each card that is cleared from the tableau, with the best possible score being 52 for removing all of the cards.
