About Paper IO

Paper IO is an addictive territory-claiming game where you control a block on a shared board. Leave your safe zone to draw a trail, then return to fill the enclosed area as your territory. Cut rivals by crossing their trail before they close their loop. But be careful — if anyone hits your trail while you are outside your zone, you lose! Strategic movement and quick thinking are the keys to dominating the board.

Conquer the board in Paper IO! This beloved .io-style game challenges you to claim as much territory as possible while defending your trail from rivals. Every loop you close expands your domain, but venturing out is always a risk. Outmaneuver opponents, steal their territory, and become the ultimate board champion!
