Paper IO 2 is a territory-capture .io game where you draw loops, claim space, protect your trail, and cut off rivals before they steal your land.

Here's a quick look at the game:

What is Paper IO 2?

Paper IO 2 is a browser arena game about taking over as much of the map as possible. You control a colored block that moves across a blank field, paints territory, and expands your area by drawing a path back to your own color.

The main risk begins when you leave your safe zone. Your trail becomes exposed until you reconnect it to your territory. Other players can hit that trail to eliminate you, and you can do the same to them when they make a risky move.

How to Play Paper IO 2

Start by claiming small sections near your base. Move outside your colored area, draw a clean loop, and return to your land to lock the space into your territory. Larger loops can capture more area, but they also keep your trail exposed longer.

Watch nearby players before expanding. A rival can cross your trail while you are outside your territory, ending your run instantly. If another player leaves a long trail, move toward it and cut across before they return home.

Your goal is to cover more of the map while staying alive. You can grow from the edges, defend your center, or attack exposed enemies to remove their space. The safest runs balance small captures with sudden attacks on careless players.
