Yukon solitaire

In Yukon solitaire, you need to collect 4 piles of cards of each suit from aces to kings on the platforms above. You can drag piles of face-up cards, no matter what order they are in. A card and the entire pile on it can be placed on another card if it is of the opposite color and one higher in rank. Only the king can be placed in an empty cell, or a pile starting with the king.
