Calculation Solitaire is a solitaire card game where the player organizes the cards by multiples of a number the is associated with each foundation pile. The first column by multiples of one, second by multiples of two, third by multiples of three and fourth by multiples of four. In this version of Calculation Solitaire, the player can place as many cards as he likes in the discard pile.
When you play Calculation Solitaire your goal is to arrange the cards in the foundations without regard to suit, and in an order that is a multiple of the card next to each foundation (Ace being 1). In the column with an Ace next to it, cards are arranged starting with the 2, and each successive card is incremented by 1. With the column that has a 2 of clubs next to it, the first card placed is a 4, and each successive card is incremented by 2. The foundation with the three of clubs is started with a 6 and incremented by 3, and the foundation with the 4 of clubs next to it is started with an 8 and incremented by 4.
The arrangement looks like this:
2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 - J - Q - K
4 - 6 - 8 - 10 - Q - A - 3 - 5 - 7 - 9 - J - K
6 - 9 - Q - 2 - 5 - 8 - J - A - 4 - 7 - 10 - K
8 - Q - 3 - 7 - J - 2 - 6 - 10 - A - 5 - 9 - K
Cards can be moved to the five columns without regard to rank or suit. However, once a card has been moved into the columns, it can only be moved out of the columns to be moved into a foundation. No cards can be moved from one column to another. The game deck can be clicked to add a card into the discard pile from the stock pile. The player can move this card to the columns, or to the foundations. In most versions of Calculation Solitaire, the player can only have a single card in the discard pile at a time. If this is too difficult for you, try playing Quick Calculation Solitaire, which allows the player to add as many cards as he likes to the discard pile from the stock pile.
