Odds of winning: Very High

Win about 4 in 5 games (80%).

Winning is mostly determined by skill. A small amount of luck is involved.

Move all cards to the eight foundations.

There are eight foundations.
An Ace may move to an empty foundation.
The foundations build up by the same suit.
For example the 4♠ may move onto the 3♠ and the 4♦ may move onto the 3♦. Starting with the 4♥ the following sequence can build on top 5♥ 6♥ 7♥ 8♥.
Once on the foundation, the top card can continue to move as needed to build sequences on the tableau.

There are ten tableaus.
A King may move to an empty tableau. No other cards may move to an empty tableau.
The tableaus build down by alternating colors.
For example the 7♠ may move onto the 8♦ and the 7♥ may move onto the 8♣. Starting with the 7♥ the following sequence can build on top 6♠ 5♦ 4♣.
Any card or stack of cards may move together as a group. Any stack of cards may move together, regardless of their build (no restriction on rank, suit or color).

Double Yukon has about a 4 in 5 chance of winning (80%). Improve your chances with these 5 tips:

Always move available Aces to the foundation.
Do not empty tableau piles unless there is a King available to immediately fill it.
Expose the face-down cards as soon as possible. When all cards are face up, the game is almost always winnable.
Do not always move a Two onto an Ace. A Two allows a covered Ace to move.
Starting with the top exposed cards, look for cards that can move onto it. Prefer the moves the expose the face-down cards. Lets say the 8♠ is one of the top cards, if you have 7♥ and 7♦ available, choose the one that provides the most benefit. Plan your moves ahead that provide the biggest long term gain.
