Paper.io is a territory claiming game where you expand colored territory on a shared grid by forming loops back to your existing area. Every player is doing the same thing simultaneously. The catch: while your trail is exposed between your territory and where you are, any opponent crossing it eliminates you.
The tension is the exposed trail. The further you travel from your territory to claim more space, the longer your vulnerable trail becomes. Aggressive expansion claims large areas but creates long exposure windows. Conservative play is safer but leaves you with small territory.
Eliminating other players by crossing their exposed trails while protecting your own is the highest-value action in the game. One elimination can simultaneously remove a threat and capture large chunks of territory. Works on any browser, no account needed.
