Yukon is a solitaire game where the object is to discard all cards to the foundations where the aces are already dealt.
Build from Aces to Kings in suit on the empty stacks with circle (object stacks).
On the seven main stacks, you can build downward in alternating colors. A topmost card can be dragged to an object stack. Any card that is open, even though the stack may not be ordered downward in alternating suits, can be dragged to another main stack. Only Kings may be placed on top of empty main stacks.
