Calculation is a difficult game with a slim chance of winning.
- The four foundations start with an ace, 2, 3 and 4.
- Build up the first foundation in ascending order, ace to king, regardless of suit.
- Build up the second foundation in 2s: 2, 4, 6, 8, 10, Q, A, 3, 5, 7, 9, J and K.
- Build up the third foundation in 3s: 3, 6, 9, Q, 2, 5, 8, J, A, 4, 7, 10, and K.
- Build up the fourth foundation in 4s: 4, 8, Q, 3, 7, J, 2, 6, 10, A, 5, 9, and K.
- You can turn only one card over from the deck at a time.
- Move cards from the deck to a foundation, or from the deck to a stack.
- You can pile cards on to the stacks in any order.
- Once a card is on the stack, it can only be moved if it is the top card. It can only be moved from the stack to a foundation and not from stack to stack.
- Win by moving all cards to the foundations.
- Example: In the illustration, several cards have been moved from the deck to the stacks. Now you can move the 8 of diamonds on to the 4 of clubs. Then you can move the queen of clubs on to the 8 of diamonds. The six of hearts from the deck can go right on to the 3 of clubs. Then the 9 of hearts can follow in to the 6 of hearts.
