Paper IO Introduction
Paper IO is a free multiplayer IO territory game. Control a colored cube, draw loops across the map to claim land, and grow your zone — but guard your tail, because one touch from a rival ends your run.
How to Play Paper IO
Controls: Use the Arrow Keys or W/A/S/D to steer your cube; on mobile, swipe in the direction you want to go.
Leave your territory to draw a line, then loop back inside to claim the enclosed area. Capture as much of the map as you can, and cut off other players mid-trail to eliminate them.
Paper IO Tips & Tricks
Claim Small Loops First
Short, quick captures are far safer than one giant risky loop.
Watch Your Tail
Your trail is your weakness; never draw lines near enemy cubes.
Hunt Careless Players
Chase rivals while they are outside their zone for easy eliminations.
Hug the Map Edges
Expanding along the border limits how many enemies can attack you.
