Not Not – A Brain-Buster is a game where you will swipe your character in the direction that is indicated by the arrows. Each level contains different and unique challenges that require your logic and dexterity to solve.

In the classic mode, you will discover a new concept on each level.

Challenge mode allows you to play as far as possible following more and more complex instructions.

The game will be more difficult as you progress, and at the end of each level, you will be rewarded with a score that will help you to compare your progress with other players.
