What is Not Not?

Not Not is a reaction and attentiveness game in which the user has to follow the instructions displayed on the screen. Choose the classic format by completing levels sequentially, or test yourself as part of an endless challenge. The first mode consists of thematic blocks – denial, emptiness, colorist, logic, colorblind, impossible, missing door and liar. The second mode is a chaotic jumble of the entire spectrum of conditions.

The gamer will be familiar with the mechanics at the start, but in any case, he will have to carefully read the information on the screen and perform specific actions with the black cube. Moreover, this must be done before the cherished moments expire. An unwitting participant in a logical adventure is a miniature figure of a person who constantly has to move left, right, up or down at the direction of the user.

Features:

  • two conceptually different game modes to choose from;
  • a hardcore challenge to the user’s patience and intelligence;
  • execution of constantly changing conditions for a while;
  • three lives to complete each level;
  • achievements and leaderboard;
  • swipe control.

Puzzle Not Not develops spatial and logical thinking, improves concentration, teaches you to work with visual images and has a positive effect on the development of cognitive abilities.
