Calculation Solitaire

Four foundations each build to a King by a different interval — by ones, twos, threes, and fours — regardless of suit. Draw one card at a time from the stock and place it on any of the four waste piles, or directly onto a foundation if it fits. The top card of any waste pile may always be moved to a legal foundation. Careful planning of your waste piles is the key to winning.
