Yukon is a solitaire card game very similar to Klondike. In Yukon, all the cards are all dealt out the beginning of the game into the columns. When building on the columns in Klondike you need to alternate colors, but in Yukon you can build the columns down alternating suit. For example you can place a 6 of clubs on top of a 7 of spades. Like in Klondike your goal is to build up the foundations from Ace to King by suit.
