Count Moving Balls

This is a game that trains your dynamic vision and brain by counting the number of balls that keep moving for each color.
By tapping the number of the same color as the ball, the number will increase by one.
When each number is the same as the number of balls of that color, tap the "OK" button.
The score is determined by how many correct answers you get in 30 seconds.
If the answer is incorrect, the score will decrease.

You can turn off the sound by unchecking "Sound" in the menu item.
You can turn off vibration by unchecking "Vibration" in the menu item.

It seems that brain training with a time limit makes the brain more active by being conscious of answering quickly.
