Agar3.fun — Free Web3 .io Blob Battle Arena

Agar3.fun is a free, real-time multiplayer browser game in the style of agar.io, with a Web3 twist. Control your blob, eat food and smaller players to grow, evolve as you get bigger, and survive the arena. No download required — it plays instantly in your browser on desktop and mobile.

How to play

• Move your blob with the mouse (or your finger on mobile) to absorb food and grow.
• Eat players smaller than you — and avoid the bigger ones.
• Use your weapon (sprint, laser, split, poison) and dodge the Void Rifts.
• The last blob standing wins the arena.

Game modes

Play Solo, Zone Battle (shrinking-zone battle royale), endless Survival, or jump into real-time multiplayer arenas against other players.
