Calculation Solitaire begins with 5 empty piles of cards, and all the cards with the exception of the Ace, 2, 3, and 4 of Clubs in the stock pile. The player can deal cards one at a time from the stock pile into the waste pile. The waste pile can only have one card on it at a time, and the card that is there must be moved to one of the foundations, or to one of the piles. The piles can have any card placed on top of it, without regard to any of the cards that are underneath. The foundations are built up in multiples. The first pile starts needing a 2, then a 3, then a 4, and so on building up by 1. The second foundation must be built up by multiples of 2, starting with a 2, then a 4, then a 6. The third pile must be built up with multiples of 3, and the fourth pile with multiples of four.
