Circles is a simple, yet addictive memory game.
The rules:
The game is divided into up to 100 levels.
In each level a new circle is placed on your screen and you have to distinguish it from other circles born in the previous levels.
Every circle is a little bit unique, their size and position are random.
You have to be very perceptive and careful not to tap the same circle twice in a single game session.
Sounds simple? Try to go trough level 20, 30 where you have to remember the position of 30 similar circles :).
Play fast to achieve better high-scores.
Wish you good luck.
