About Senpa.io

This is a cross platform multiplayer online action game.
You start the game as a tiny bacteria (cell) in a petri dish. You must try to survive by avoiding attacks by bigger players. At the same time, you eat food and become a bigger and bigger cell, until you are large enough to eat other players.

The game is very immersive and has very active gameplay with a lot of action. All your enemies are real people, so you must find a good strategy to become the biggest cell on the gamefield! Anyone can become big in one moment, or lose all their progress in the next - so be careful :) Game mechanics are similar to other .io games which you probably already know - but this is not agar or diep!

This game was made by the same developers of Agar.io and is constantly updating with new and unique features!

Warning! This game is very addictive and takes alot of effort from you to survive with so much action.
So if you die in the beginning, be patient, and improve your skills :)

How to Play Senpa.io


Senpa.io is simple to play, you simple use your mouse cursor to navigate around the screen, and you use space to split your cell, and W to eject mass. You also have a hotkey menu and you can create many custom controls!
