Calculations Solitaire is one of the great classic Solitaire games!

The foundations start with one Ace, 2, 3 and a 4.

The goal is to build each foundation, regardless of suit, in intervals of one, two, three and four respectively.

For expample the first foundation is build like Ace, 2, 3, 4, 5 ... etc. The second one is like 2, 4, 6, 8, 10 ... etc.

The top card of the deck can be played on a foundation or on any of the four waste piles.

There are no restrictions on how to build the waste, but once a card is placed there it can only be moved on a foundation.
