# How to Play Calculation Solitaire

There are two types of card games. Some can be played without thinking and others require your full attention. Just as its name suggests, __Calculation Solitaire__ falls in the latter category. This is one of the few variations of __solitaire__ that requires players who have sharp minds and a considerable amount of skill. Do you think that you have what it takes to play calculation solitaire? Here is how to play it.

**But First, What is Calculation Solitaire?**

This variation of solitaire goes by many names. In some parts of the world, it is known as Four Kings Solitaire, Hopscotch, or Broken Intervals. In France, where the game originated from, Calculation Solitaire is referred to as La Plus Belle. Irrespective of the name, the setup is the same and so is the gameplay.

Calculation Solitaire is played using the usual 52 card deck. And unlike other variations of solitaire, a skilled player using a solid strategy has an 80% chance of winning. If it’s your first time, your chances of winning a game of Calculation Solitaire are at 20-30%. This is quite a good figure, bearing in mind most solitaire variations are won through luck and players have lower chances of winning.

**How to Play**

Being a game that is associated with math, in Calculation Solitaire, the suits of the cards do not matter. The most important thing is the ranking of the cards. Setting up this game requires space for four foundation piles, four waste piles, and a stockpile. The objective here is to build the four foundation piles which start with an Ace, two, three, and four in a plus 1, plus 2, plus 3, and plus 4 sequences. This may sound confusing but hold on, we will clarify things later on.

As mentioned above, during set up, you will need to create the 4 foundation piles with an Ace, a two, three, and four. Don’t worry about the suit. These cards should be placed horizontally from right to left. Beneath the foundation pile, make room for four waste piles. These will be used during the game. The cards you will be left with will be your stockpile and that’s where you will be drawing cards from.

To play the game, you have to build foundation piles following the sequence we had talked about earlier. Here is how you are going to do it;

In the first pile, which starts with an Ace, you must play the next ranking card which is a 2. It should be followed by a 3, 4, 5, 6, and so on till you reach a King.

The second pile that starts with a 2, you should play a card that goes up 2 ranks higher. The next card to be played here should be a 4, 6, 8, and so on.

The third pile that starts with a three, a player should go up three intervals. The next card should be a 6, 9, Q, 2, 5, and so on.

And as you may have guessed, the fourth pile requires players to go up 4 ranks higher. Cards following the 4 should be 8, Queen, 3 until you exhaust all cards in the stock and waste pile.

The game is won when a player successfully moves all the cards in the stock and waste pile to the foundation piles. Because there are 4 piles, in each, you can make 13 moves. The final move should be when you reach a King. And that’s why when playing Calculation Solitaire, you have to play the Kings strategically.

During gameplay, cards are sourced from the stockpile. If you draw a two, you can put it on the Ace. If you draw a 6, put it on the 3. If you happen to draw a card that doesn’t fit any sequence in the foundation pile, place it anywhere on the waste pile. Only the top card from the waste pile can be played back to the foundation.

**Calculation Solitaire Rules**

The rules of calculation solitaire are quite simple. The first rule is that when building foundations, always follow the sequence of a particular pile. If it’s the Ace, only add cards a rank higher that is 2, 3, and 4 until you reach Kings. No matter which pile you are playing, follow the sequence until you reach a King.

Another rule that is very important to follow is that cards from the stockpile should be played to the foundation pile. If it can’t fit any sequence, place it anywhere in the waste pile. The bottom card on the waste pile is the only one that can be played to the foundation. After playing all the cards to the foundation piles, you will have won your first game of Calculation Solitaire.

**Calculation Solitaire Tips**

From the above, you can see that setting up and playing Calculation Solitaire is easy, especially if you have understood which sequence to follow in the foundation piles. However, Calculation Solitaire is more of a strategic game and that’s why you should make use of the tips we are going to share with you.

The first and most important tip when playing Calculation Solitaire is to never hesitate when making a move from the stockpile to the foundation pile. If a card can be legally moved, then please do so. Waiting to make a move can leave the card buried in the waste pile and unavailable for play.

It is also important that you remember the game’s sequences. This will allow you to calculate moves mentally before you can physically play them. Always keep an eye on your waste pile and don’t bury cards that can be used later.

While we are still on the tips for Calculation Solitaire gameplay, you need to be very careful with Kings. If you place them aimlessly on your waste pile, they can block certain moves. A smart Calculation Solitaire player places all Kings in one waste pile. This strategy ensures that no move is blocked during gameplay and your Kings are safely tucked in one corner, waiting to be played at the end.

**Final Thoughts**

Even though this variation of solitaire has higher chances of winning, it does require regular exercise for you to become a skilled player. Have the sequence in which the cards are to be played on the foundation piles at your fingertips. And combine that with the above tips, you will see how interesting a game of Calculation Solitaire can be.
