To Zero

To Zero - Develop your mind with puzzles in various difficulties: very easy, easy, normal, difficult. Engage in your own self-development at any age, even if you don't go to school now. Put the game on pause at the right moment, use the hint if you can't solve the puzzle, go through the level again if you realized that there is no way to move on. Start playing the game from the easiest mode, so that later, when you are ready, you can start trying your skills at a more difficult level.
