2016/03/22. Long time no updates? That's ok because now we are ready to present you whole new gamemode - EatForSpeed - and to be honest, this is actually 2 modes in 1 - Race + Arcade! And as you could have guessed - these are racing gamemodes! You start together at the left side of the narrow map and your task is to be the 1st at the right side!

The Race mode - is plain and simple racing game - avoid the food cells, stay at the lowest mass possible and don't hit the deadly flying tires. Also you cannot split but use space to shoot some mass (aka NITRO) behind you to gain speed. Or shoot the enemies with W to slow 'em!

As for the Arcade mode - this one features lots of boosters:
1) open sewers cover - drop there and get teleported to another random sewer behind you
2) UFO spaceship - it steals your mass
3) Nitro-booster to gain some boost))
4) closed sewer cover, which slows you down

and finally

5) Mr.Bum - he loves eating the cells

As for the flying tires, they won't kill you but just push you away

Highscore are based on the best time to complete the race

Have fun and good luck!

How to play in Petri dish

Choose the game mode (FFA, HardCore, MegaSplit and etc.), select a map (more people - more difficult, less people - easier), press play.

You need to get a lot more mass than the others. Then you get to the top. This is the essence of agar game.

If you're tired of simple modes of agar then choose one of our exclusive game modes. Each mode has its own more complex rules. You can read the description on the right when you select a mode. When you'll select a map you get to know what the difference is. For example, higher limits or more food.
