About 2 2 is a popular online arcade game developed by Voodoo.

The gameplay in 2 is simple but highly addictive. You have to control a square-shaped avatar or paper that leaves a colored trail behind as it moves across a blank, grid-like game board. The goal is to expand your territory by enclosing areas with your colored trail. The catch is that other players are doing the same, and you must avoid colliding with their trails.

To expand your territory, you need to draw closed shapes by circling them with your paper's tail. Once you complete a closed shape, the area inside becomes your territory, and it's filled with your paper color.
