An offline .io-style arena. Steer your blob around a big scrolling grid, gobble pellets and smaller blobs, split to snipe prey, and dodge bigger blobs and spiky viruses. You play against 15 computer bots with silly generated names (no real online players), with a live top-10 leaderboard, zoom-out camera as you grow, and your best mass saved.

How to play

Your blob follows your pointer or finger. Eat colored pellets to grow, and swallow any blob at least about 10% smaller than you. Bigger blobs move slower. Split to launch half your mass forward to catch prey; the pieces merge back after a cooldown. Eject mass to shed weight or feed viruses. Big blobs that touch a spiky green virus burst into many pieces. You lose when every piece of your blob is eaten.

Controls

Tips and strategy

  • You can only swallow blobs at least 10% smaller than you, so compare sizes carefully before chasing a similar-sized rival.
  • A piece needs at least 36 mass to split, and split pieces must wait 8 seconds or more before they can merge back.
  • Viruses have 100 mass, so once you pass about 110 mass, touching one bursts you into pieces; steer around them.
  • Eject mass into a virus to feed it; when it gets full, it fires a new virus in the direction you fed it.
  • Mass above 60 slowly decays, so keep eating pellets and smaller blobs to hold your size.

Blob Arena FAQ

Is Blob Arena online multiplayer?

No. Blob Arena runs entirely offline against 15 computer bots with generated names. There are no real online players.

Why does my blob get slower in Blob Arena?

Speed drops as mass grows, so big blobs move slower than small ones. Splitting launches half your mass forward for a quick burst toward prey.

When do I lose in Blob Arena?

You lose when every piece of your blob has been eaten. Your best mass is saved in this browser.
