Klondike, also known as Canfield, is a card game for one player and the best known and most popular version of the patience or solitaire family, something which defies explanation as it has one of the lowest rates of success of any such game

In the U.S. and Canada, it is so well known that the term "Solitaire", in the absence of qualifiers, typically refers to Klondike and is considered its other name. Equally in the UK, it is often just known as "Patience" Elsewhere the game is known as American Patience.
