## What is Calc Ball?

Trace the ball to bring the total to 10! Full math brains. Easy for all people

In the stage. Five types of the ball have Numbered from 1 to 5. You consider quickly which combination makes  10 with ball number sum. For example, 2 + 2+ 2 + 2 + 2 = 10, and also 1 + 2+ 3 + 4 also 10! you should find a combination and trace on the screen.

 You can enjoy 3 types of mode!

The normal mode is a fun mode where you can aim for a high score. In the future, you may be able to see the world rankings as well (we'll make one if it becomes popular).

The time limit is 45 seconds. As the ball is erased, the time increases as you erase it, so if you erase the ball fast enough, you may get a super high score.

In Wonder Mode, you can enjoy a mysterious sensation like in Alice's Wonderland, which is not available in other modes. Aim for a high score in each mode.

This is a whimsical mode that you can play in occasionally. Don't miss it when you can press the buttons. For those who can't wait, we also offer a commercial button that lets you play when you see a commercial.

Enjoy it when you find it.

The story mode is a mode where you have to solve the problems given to you. New aspects will be added in the future. Great for newcomers to learn how to play games.

Enjoy !!
