The goal of Yukon Solitaire is to move all cards to the four Foundation piles from Ace to King in the same suit.
Using one deck, all cards are dealt to the layout. There are 7 Columns. Each Column is dealt one more face down card than the previous Column starting with 0 face down in the first column. Columns two through seven are then dealt 6 more cards each face up.
Foundations are built UP and IN SUIT starting with an Ace and ending with a King. For example, a 2 of Clubs can be placed on an Ace of Clubs, then a 3 of Clubs, then a 4, 5, 6, 7, 8, 9, 10, J, Q, up to the K of Clubs. The same holds true for the other suits.
Columns are built DOWN in ALTERNATING COLOR similar to Klondike. For example, a red 6 may be placed on a black 7.
Any number of face up cards may be moved to another Column provided that the above build rule is followed. It does not matter whether the cards being moved are already in sequence or not. For example, a red 6 may have a King and a 2 on it. Those three cards may be moved to a black 7.
The topmost card in any Column is available for play to either another Column or a Foundation. When a face down card is the topmost card in a Column, it is flipped face up.
Empty Columns may be filled with Kings or Kings with other cards dragged along.
Yukon Solitaire is a cousin to Klondike. Layout and game play are similar. If you like Klondike, you will probably like Yukon Solitaire also.
