Yukon (0)

The general algorithm for playing Yukon solitaire is as follows: For each stack, see which face up cards in the other stacks can be moved to the top of the stack.

If there is only one unordered card which can be moved to the top of the stack, go ahead and move it.

If there are two or more cards which can be placed on the stack, make the move which will lead to turning over a face down card. If neither move will result in a new face up card, make the move which will enable more moves.

Repeat until the game is won or there are no possible moves.
