# Solitaire card games/Calculation

This game is also known as Broken Intervals, it has been suggested that there is a very good chance of winning if you are skilled.

## Set up

1. Remove one A,2,3 and 4 from the pack (suit does not matter in this game), they form the foundations. 2. All the foundations are to be built up to kings, each differently

• The ace is to be built up by 1s up to Ks in this order: `A 2 3 4 5 6 7 8 9 10 J Q K`
The 2 is to be built up by 2s in this order: `2 4 6 8 10 Q A 3 5 7 9 J K`
The 3 is to be built up by 3s in this order: `3 6 9 Q 2 5 8 J A 4 7 10 K`
Likewise, (you should be getting it now), the 4 is built up by 4s like this: `4 8 Q 3 7 J 2 6 10 A 5 9 K`

3. The wastepile is initially empty, it consists of four piles of cards, which are laid below the four foundations.

## Play

1. Turn up cards from the stock, one at a time, and build them on one of the foundations, if that's not possible, put it in one of the four wastepiles.
2. You can move cards from any wastepile onto one of the foundations when possible.

## Variation

1. Do not lay out A,2，3，4 initially) and to use only three tableau piles instead of four.

Although playing this variation makes the solitaire quite difficult, a very skilled player will still be able to win at least two games out of three.
