About Blob.io

Blob.io is a fast, addictive cell-eating .io arena you can play free in your browser with no download. You start as a tiny cell in a wide, camera-following arena packed with glowing pellets and rival blobs. Steer with your finger or mouse to hoover up pellets and swallow anyone smaller than you, growing rounder and heavier with every bite. But size is a trade-off: the bigger you get, the slower you move, and every giant on the map sees you as lunch, so spacing and nerve matter as much as appetite. Two action moves keep the chase alive — Boost to blast forward and close a gap or escape a hunter, and Split to fling a piece of yourself at prey or dart through a tight lane. As your mass climbs you evolve through named tiers and rise up the live leaderboard. Score banked in a run becomes a persistent meta-currency you spend in the Skin Shop on purely cosmetic blob colors and skins — no pay-to-win, just style. It's a simple loop of eat, grow, dodge, and dominate that's easy to pick up and hard to put down.

How to play

Your blob constantly follows your finger (mobile) or mouse cursor (desktop) — move toward pellets and smaller blobs to eat and grow, and steer away from anything bigger. On desktop, press Space to Boost forward and W to Split; on mobile, tap the on-screen Boost and Split buttons (both have a cooldown, shown as a ring, so time them). Tips: hug the pellet fields early to build mass safely before picking fights; only Split when you're clearly bigger than your target, since splitting temporarily halves your defensible mass and leaves you vulnerable; and save Boost as an escape tool when a giant lines up on you rather than burning it on offense. Watch the leaderboard to learn who to avoid.
