This is a fun, mathematical puzzle game that encourages performance of arithmetic operations and fast decision-making.
The objective of the game is to match the number on the cannon to the number on the box above it. You do so by adding, subtracting, dividing, and multiplying the number by the ball on the right. You can change the operator by pressing the buttons at the bottom of the screen. You only have a short amount of time to decide what operation you wish to perform, and you complete the operation by sliding your finger across the screen to the left and moving the ball to the left.
The number on the cannon cannot be below zero or above 100, and you cannot divide by zero or leave a remainder after division. Otherwise, your cannon will get hit. If you get hit three times, the game is over.
You can skip a ball you don't want by using the discard button on the left. However, if you use it, you can only use it again after five turns.
When the numbers on the cannon and the box match, the cannon shoots out a cannon ball to destroy the box. The more boxes you destroy, the higher the score you earn, and the higher your level will go.
Also, the game has a timer. When the time is up, the game is over. However, every time the cannon fires, the timer increases by ten seconds, and the maximum time it can reach is three minutes.
Other than the main game, there are additional features, such as:
- A tutorial section.
- A Game Center leadership board.
- A share button with iOS' Airdrop functionality.
Let's see how high your level and score will be.
Have fun.
