Pro Yukon Solitaire is a free solitaire card game for the PC similar to Klondike (Microsoft) solitaire. The difference is all cards are dealt into 7 columns at the beginningn of the game. Pro Yukon Solitaire is more difficult than traditional Yukon Solitaire because more cards are initially dealt face down and can not be moved from one column to another until all the cards above them have been removed.
