Canfield Solitaire is a solitaire game that requires skill. The "Turn One" variation is simple and fun, while the "Turn Three" variation (original version of the game) is very challenging. This was the most famous solitaire game before the "traditional" solitaire game came along.
The objective is to move all cards, in ascending order in suit, to the foundations.
There is a legend that this solitaire game was created by Richard A. Canfield, who owned a casino in New York during the 1890s. In this casino, punters could buy a deck of cards for $50 to play this game. Players won $5 for each letter sent to the foundations and $500 if they won. As the original version of this game is the "Turn Three" variation, it was very difficult to recoup the initial investment of $50. Despite being a difficult game to win, the game was very successful and was responsible for making Canfield a rich man.
There are many variations of this game, one of them being the "Turn One" variation. This variation makes the game much easier and more fun, as it's quite difficult to run out of moves.
In England, Canfield is known by the name Demon. This name is probably due to the fact that the game in the original version ("Turn Three") is very difficult.
