Paper.io is an online multiplayer game where the main goal is to conquer as much territory as possible on a digital map. Each player controls a colored square that leaves a trail behind as it moves. The space enclosed by the trail becomes part of your territory once you connect it back to your existing zone. But watch out — if another player touches your trail before you connect it, you're out.

The paper io game is simple but incredibly addictive. It combines elements of classic arcade games with modern, competitive gameplay. The concept may remind some players of Snake or Tron light cycles, but with a unique twist of territorial conquest.
