Paper.io is a free-to-play online multiplayer game where players control a small square block that leaves a trail behind it as it moves. The objective is to capture as much territory as possible by enclosing areas with your trail and converting them into your color. The more area you conquer, the higher your score. However, your trail is vulnerable—if another paper io player crosses it before you complete the loop, you're eliminated.
