About this game

This is an app that quickly solves addition and subtraction.

To prevent children from getting too excited, we have included a function to prevent children from playing too much.
Please note that this feature cannot be turned off.

- After playing for about 10 minutes, there will be a break of about 5 minutes.
- You cannot play from 0 to 3 minutes and from 30 to 33 minutes of every hour.
