About Agar.io

🟢⚪ Agar.io — The classic, original viral .io game that started it all!

In Agar.io, you control a tiny cell in a giant petri dish. Your goal? Eat or be eaten!

✅ How it works:

• Move your cell around using your mouse (or touch controls).
  
  

• Eat smaller cells (including other players!) to grow larger.
  
  

• Avoid bigger cells — if they touch you, they’ll absorb you!
  
  

• As you grow, you become slower and need to use strategy to trap and split to catch smaller cells.
  
  

• You can split your cell to move faster or catch fast-moving prey, and eject mass to feed viruses or trick opponents.
  
  

🎯 Key features:

• Simple but incredibly addictive gameplay.
  
  

• Play solo, in teams, or in experimental and party modes.
  
  

• Skins and nicknames add fun customization.
  
  

• Play instantly in your browser — no download needed!
  
  

💥 Main goal:
Become the biggest cell on the map and dominate the leaderboard!
