General
Klondike is a solitaire card game. In the U.S. and Canada, Klondike is the best-known solitaire card game, to the point that the term "Solitaire", in the absence of additional 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, as well as Fascination, Triangle or Demon Patience.
Klondike is traditionally known in England as Canfield, whereas in America the name Canfield is given to the patience game called "Demon" in England, which is a different solitaire card game devised by Richard Canfield (although Canfield himself called his game Klondike).
According to Tung (2015), the game became popular in the late 19th century, and may have been named "Klondike" after the Canadian region where a gold rush happened. Its inclusion in Microsoft Windows in the 1990s has contributed significantly to its popularity in modern times. It is considered the most popular version of solitaire.
