Micro.io

Micro.io - Play Online

Cell warfare. Pure survival. Micro.io drops you into a microscopic arena where size equals power. Eat smaller cells. Run from bigger threats. Clone mechanics? Agar.io veterans know the drill. Micro.io adds one twist: betray your team, face the Karma System.

How to Play Micro.io

Your mission is brutal. Simple. Consume glowing food particles to grow your mass. Swallow smaller bots whole. Avoid anything bigger. The leaderboard tracks top organisms. Climb it or die trying. Micro.io rewards aggression and timing.

Movement & Core Mechanics

Desktop? Cell follows your mouse cursor. Mobile? Virtual joystick bottom-left corner. No aiming needed. Just point and glide. Food particles scattered everywhere. Move over them to absorb. See a smaller cell? Ram it. Instant meal. Bigger cell spotted? Reverse direction fast.

Split & Eject Tactics

Press Spacebar (or ✂️ Button on mobile) to split your cell in half. One half shoots forward like a bullet. Perfect for catching fleeing prey. Requires minimum mass to activate. Hit W (or 💧 Button) to eject a chunk of your own mass. You shrink slightly. Why do it? Feed teammates. Bait traps. Escape through tight gaps between viruses. Strategic sacrifice wins matches.

Team Play & Karma System

Form alliances by feeding allies with W. Share mass. Coordinate splits to trap large targets. But here's the catch: betray them? Karma System activates. Game penalizes backstabbers. Exact mechanics unclear. Risk your reputation or play honest. Choose fast.

Virus Strategy

Green spiked viruses littered across the map. Touch one when you're too large? You explode into multiple tiny pieces. Death sentence against predators. But feed a virus with ejected mass (W spam)? It grows. Seventh piece makes it split and shoot forward. Use it as a weapon. Aim at giant cells. Watch them shatter.
