The aim of the game is to click on lighted circles one by one as quickly as possible.
The game finishes if:
- time is up for specific round;
- you clicked on not lighted circle;
- you clicked on black circle.
The more rounds you pass the less time you got for round passing, and the more points you receive for each click.
Also the speed of clicking matters.The faster you click on the circles, the more points you get for each press.
The game develops motility of fingers, reaction and attentiveness.
