Yukon Solitaire is kind of like the chicken-instead-of-turkey-dinner version of Solitaire games. It is very unique and not the easiest to get used to since it is played quite differently from the Klondike, Freecell, or Spider Solitaire games. You can move any stack of cards in the tableau regardless of suit, color, or order, but they must be placed on top of other cards in descending order by alternating colors. For example: A stack of Jack-7-2 may be moved onto a run that ends in a Queen, as long as the Jack and the Queen are different colors. The card game can move a lot quicker this way, but can also be a lot more challenging.
