Calculation (1989): A Retro Puzzle Classic

Released in 1989, Calculation is a puzzle game that challenges players to use their math skills to solve increasingly difficult equations. The game features over 100 levels, each with a unique target number that players must reach.

Calculation is played on a grid of numbers and operators. Players can use the numbers and operators to create equations that equal the target number. For example, if the target number is 10, players could create the equation 5 + 5 or 2 * 5.

The game starts out with relatively simple equations, but the difficulty quickly ramps up. As players progress through the levels, they will encounter more complex equations that require them to use a variety of mathematical operations, including addition, subtraction, multiplication, and division.

In addition to the main game mode, Calculation also features a number of bonus levels. These levels offer a variety of challenges, such as solving equations with missing numbers or operators.

Calculation was a critical and commercial success upon its release. The game was praised for its challenging gameplay and its ability to improve players’ math skills. Calculation has been ported to a variety of platforms over the years, and it remains a popular puzzle game today.

Gameplay

The goal of Calculation is to use the numbers and operators on the screen to create equations that equal the target number. Players can use any of the numbers and operators on the screen, and they can use them in any order.

For example, if the target number is 10, players could create the following equations:

• 5 + 5
• 2 * 5
• 10 – 0
• 20 / 2

Players can also use parentheses to group numbers and operators together. This can be useful for creating more complex equations.

For example, the following equation uses parentheses to group the numbers 2 and 3 together:

(2 + 3) * 4

This equation equals 20, which is the target number.

Strategy

There are a few general strategies that can help players succeed in Calculation:

• Start with the simplest equations. The first few levels of Calculation are relatively easy, so it is a good idea to start with these levels to get a feel for the game. Once you have mastered the basics, you can move on to the more challenging levels.
• Use all of the numbers and operators. Don’t be afraid to use all of the numbers and operators on the screen. The more numbers and operators you use, the more likely you are to find a solution.
• Be creative. There is no one right way to solve a Calculation puzzle. Be creative and experiment with different combinations of numbers and operators until you find a solution.
• Don’t give up. If you get stuck on a puzzle, don’t give up. Take a break and come back to it later. You may be able to see the solution more clearly with fresh eyes.

Conclusion

Calculation is a challenging and addictive puzzle game that will test your math skills. With over 100 levels to play, Calculation is sure to provide hours of entertainment. Whether you are a seasoned puzzle game veteran or a newcomer to the genre, Calculation is a game that you should definitely check out.
