suit. The Storehouse variant makes the game easier than Canfield. Superior Canfield, where the entire reserve is visible, and gaps can be filled by any card, not just those from the reserve. Eagle Wing (Thirteen Down): similar to Storehouse.Variegated Demon: double pack game in which Aces are always the base cards and there is a tableau of five cards. Sequences or single cards may be moved and there are two redeals. Other closely related solitaire games include Duchess and the two-deck game American Toad. Beehive is a much simpler solitaire game that uses a Storehouse layout, but requires players to match cards of the same value, and is geared towards children.Racing Demon, an English game known as Nerts or Pounce' in the US, is a real-time variation of Canfield that enables the game to be played competitively between multiple players. It was the inspiration for the commercially produced Dutch Blitz and Ligretto. Solvability Under the standard rules using a three card draw, Canfield can't be completed successfully very often. Running a computer solver on 50,000 random Canfield deals has shown that about 71% of all games are winnable. In the average game, 39.9 cards were able to be moved to the foundation. Because the reserve cards are hidden, and because the three-at-a-time dealing of cards from the stock means that cards played early in the game can impact which stock cards are available much later, it is very difficult by normal playing standards to come anywhere near theoretically possible win rates. This would make it plausible for expert-level players to claim win rates of around 35%. In the Storehouse variant, the maximum possible win rate drops to about 44%. In practice, however, Storehouse is a much easier game to win, likely due to getting all four foundations at the start of the game. Most players will be able to win close to 44% of their games, regardless of skill level, a much higher win rate than is usually achieved by casual players of Canfield.
