Elevens

Elevens is a solitaire card game using a standard 52-card deck. Cards are placed in a 3x3 grid, and pairs of cards which add up to eleven (5 and 6; 4 and 7; 3 and 8; 2 and 9; Ace and 10) are covered up; face cards (J, Q, K) may be eliminated in a set of three cards consisting of one Jack, one Queen and one King regardless of suit. If all cards are covered up the game is won; if there are no more pairs of cards that add up to eleven, and there do not exist a Jack, a Queen, and a King, the game is lost. An individual game of elevens is a game of pure chance, except for the small element of skill involved in spotting the pairs; the skill and strategic interest comes in not shuffling the cards at the end of each game, but instead collecting them up in order.
