Yukon Solitaire is a classic solitaire card game similar to Klondike. If you're familiar with Classic Solitaire you should be able to pick up Yukon pretty quickly. It has a few differences like the lack of a deck, and the columns can be built down alternating suit instead of just color. Alternating suit means you can put a spade on top of a club or a diamond on top of a heart, where in Classic Solitaire that move would not be possible.
