Paper IO
Claim territory, outmaneuver rivals and conquer the board in this classic io battle!

About Paper IO
Paper IO is a territory-conquest game where you control a colored square on a shared board. Venture outside your territory to claim new land — but be careful, because your trail is vulnerable while you are outside your zone. If an opponent crosses your trail before you close the loop, you are eliminated. Strategically expand your territory, cut off opponents, and conquer the largest possible area. With its simple controls but deep strategic possibilities, Paper IO delivers intense, competitive gameplay.

Tips & Strategies
Make small, safe expansions rather than risky large loops
Stay close to your territory edge so you can return quickly
Attack opponents when they are far from their territory with a long trail
Watch your back — opponents may try to cut off your trail from behind
Claim corners and edges first — they are easier to defend
Avoid venturing into the center early — it is the most contested zone
