what are the odds of winning a game of solitaire
Klondike (solitaire) For a standard game of Klondike, drawing three cards at a time and placing no limit on the number of re-deals, the number of possible hands is over 7067800000000000000♠8×1067, or an 8 followed by 67 zeros. About 79% of the games are theoretically winnable,[3] but in practice, human players do not win 79% of games played, due to wrong moves that cause the game to become unwinnable. If one allows cards from the foundation to be moved back to the tableau, then between 82% and 91.5% are theoretically winnable.[4] Note that these results depend on complete knowledge of the positions of all 52 cards, which a player does not possess. Another recent study has found the Draw 3, Re-Deal Infinite to have a 83.6% win rate after 1000 random games were solved by a computer solver.[5] The issue is that a wrong move cannot be known in advance whenever more than one move is possible. The number of games a skilled player can probabilistically expect to win is at least 43%.[3] In addition, some games are "unplayable" in which no cards can be moved to the foundations even at the start of the game; these occur in only 0.025% (1 in 4,000) of hands dealt.[6][7][8]
