Rules   
Calculation starts you off with four foundations, four empty columns, and a deck with 48 cards. The first foundation starts with an Ace, the second with a 2, the third with a 3, and the fourth with a 4.   

The first foundation is built in the following order, regardless of suit:   

A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K   

The second foundation is built in the following order regardless of suit:   

2, 4, 6, 8, 10, Q, A, 3, 5, 7, 9, J, K   

The third foundation is built in the following order regardless of suit:   

3, 6, 9, Q, 2, 5, 8, J, A, 4, 7, 10, K   

The fourth foundation is built in the following order regardless of suit:   

4, 8, Q, 3, 7, J, 2, 6, 10, A, 5, 9, K   

Suit doesn't matter at all in Calculation. Any cards that cannot be immediately played can be placed on any of the four columns. Only the top card on any of the columns, or the top card of the deck can be played on to any of the foundations. You win the game if all four foundations are built up to the King.   

Scoring   
Any card moved to one of the columns is worth 10 points, and any card moved to a foundation is worth 25.
