Just one line, and how many amazing pictures you can draw. This is not just an ordinary drawing machine, but real food for the mind - a puzzle. In order to interest you and complicate the task, we suggest connecting all the points on the field with one line, without taking the pencil from the screen. The first few tasks will seem simple to you, but do not flatter yourself; subsequent levels may put you in a dead end, but this is not a reason to give up. Move the convolutions and solve all the puzzles.
