Paper.io 2 is a casual online multiplayer game developed by Voodoo. In this game, players control a colored square that moves around a large, open map. The objective is to capture as much territory as possible by drawing lines as you move. When you complete a loop, the enclosed area becomes part of your domain. However, while drawing, your trail is vulnerable—if another player crosses it before you close your loop, you'll be eliminated. The game is fast-paced and competitive, with smooth, simple mechanics, offering endless fun as players try to expand their territory and dominate the map while avoiding collisions with other players.
