The game “Papar io” is simple in essence and in execution, but very difficult to pass. The goal is to capture territory and expand their possessions. At the very beginning, the user has only a small base - Papar. This is a square of a certain color. A dot begins to move from it, leaving a trail behind it. By controlling it using the keyboard, the gamer must return the tip of the “tail” to the base. When the line closes, everything that is inside it will turn into “your” color and become part of your territory. But if one of the participants of “Papar io” crashes into the track before you close it at the base, the game will end.
