Similar to Klondike with more flexibility so you can build some very long stacks!
The significant difference betweek Yukon and Klondike is that a (face up) stack of cards can be moved without being in any order, so long as the starting and target cards are in rank order and alternating color.
Also, there is no stock; all cards are dealt at the beginning.
Difficulty: Medium to play, medium to win. Mostly skill.
Variants: Scorpion, Russian Solitaire (aka Yukon Strict)
