Mission briefing

Welcome to Shrinkzone, a lightning-fast, doodle-style battle royale where survival depends on your appetite! Start off as a tiny blob and devour food scattered across the map to grow larger and stronger. But beware — other players are doing the same. Use quick reflexes and clever movement to avoid the giants and hunt down the weak. As the shrinking safe zone forces players closer together, only the smartest and hungriest will survive. Are you ready to dominate the arena and claim the top spot?

Field manual

Keyboard • Move – WASD Mobile • Move – On-screen joystick

Launch orders: press Launch mission above and the game loads on this page itself — nothing downloads and no form stands between you and the first move. It is designed for a portrait (upright) screen and takes its orders from mouse, keyboard or touch, depending on the mission. It is built tall, for an upright screen — a phone held normally frames it best, though any window will run it. If it offers a fullscreen control, use it — a fight this size deserves the whole screen.

Field notes for .io arena operations

• Eat at the edges. The centre of an .io arena is where the giants feed; the rim is where small players grow fat on leftovers nobody bothers to chase.
• Never chase a smaller player in a straight line for long. Every second of pursuit is a second the whole arena can see, and something bigger is always watching the chase instead of the chased.
• Use your size as a rumour, not a shield. The moment you make the leaderboard, you become content for everyone's evening — spend big size on safety, position and patience.
