Classic Yukon Solitaire

Yukon is a classic solitaire.

The goal is to move all cards to the four foundations at the right by suit from A to K.

You can move a group of cards to another tableau pile if the starting card of the group is in alternate color and of an immediate lower ranking with the top card of the other tableau pile.

An empty tableau pile can be occupied by a K or a group starting with a K.
