Agario Game

Agar.io is the game that started the whole ".io" genre: you control a small cell floating in a big shared arena with dozens of real players, and the entire goal is to get bigger while staying alive. Eat the colored pellets scattered around the map to grow slowly, or eat a smaller player's cell to grow a lot faster — but anyone bigger than you is trying to do the same thing to you.

There's no round structure or levels. You just keep growing, splitting off pieces of your cell to snipe smaller players who'd otherwise outrun you, until either you're one of the biggest blobs on the leaderboard or someone else eats you and you start over from a tiny cell.

Controls

• Mouse — move your cell toward the cursor.
• Spacebar — split your cell in two, launching one half forward to catch something out of reach.
• W — eject a small blob of mass, useful for feeding a teammate or baiting an enemy.

Tips

• Don't split unless you're sure of the catch — a split cell is smaller and slower for a few seconds, which is exactly when bigger players pick you off.
• Stick near the edges of the map early on, where there are fewer big cells hunting for easy meals.
• Ejecting mass toward a virus can pop it and scatter pieces that hurt a much bigger cell chasing you — useful as an escape trick, not just a feeding gesture.

It's built for short, replayable sessions — there's no save file or progress to lose, just whatever size you reach before your current cell ends.
