Rainbow Canfield Solitaire is a challenging card game that is derived from Canfield Solitaire, designed to be played at a casino. It offers a test for the player's skills in solitaire games with its tough gameplay.

Traditionally, the game was incredibly difficult to win, with players only moving an average of 6 cards to the foundations. This meant that the house could keep $20 of the $50 the player had paid for the cards, while the player would only win $30. However, Rainbow Canfield Solitaire changes the rules of the game ever so slightly, giving the player a better chance of winning.
In Rainbow Canfield Solitaire, the player deals cards from the deck one at a time instead of three at a time, which dramatically increases their chance of completing the game. This makes it a more accessible and rewarding version of the game, which is perfect for players who want to experience the thrill of Canfield Solitaire without feeling discouraged by its difficulty. Overall, Rainbow Canfield Solitaire is an excellent solitaire card game that is challenging, fun, and rewarding all at the same time.
