What is Agar.io?
So you are a brand new Agario player? Welcome! You play as a cell that gets bigger by "eating" cells smaller than you. The controls are very easy to learn but very hard to master. The best part about Agario is how fast you can get started. You don't need to download anything, install anything, or change any settings.
How do I play Agar.io?
- Move your cursor with your mouse, and that is where your cell will move.
- Press SPACEBAR to split into two equal halves
- Press 'W' to eject some mass
Ok, I know how to control it, but what do I DO exactly?
When your cell is small, focus on eating the small pellets you see scattered around the map. They will help you grow in size and become big enough to eat other cells.
How do I control my speed?
You can't, the bigger you get, the slower you will move. The game is designed this way to balance
How come I can't eat this cell that is smaller than me?
You have to be at least 25% larger than your victim to eat it. If your sizes are less than 25% different, you will just pass over/under each other without anything happening.
What are those green cells with spikes?
Those are "viruses", they only hurt you if you are bigger than them.
Hide behind the viruses to use them as defense against large cells.
If your cell is larger than a virus, running into one will shred your cell into pieces.
How do I split my cell, and why would I want to do that?
To split your cell, press 'W', half of your cell will shoot forward in the direction of your cursor. This is used to eat other cells or escape death.
That's great, but now that I've split, how do I combine my split halves again?
Remember that cells won't absorb each other unless 1 is at least 25% larger than the other. Keep absorbing cells or pellets with one of your halves until it is big enough to absorb the other. Move your cursor so that the two halves touch, and the bigger half will absorb the smaller half.
I want to look fancy too, why do some players have special skins on the cells?
To get a particular look, just type the name of the skin as your player name when you start the game. To see a list of all the currently supported skins, visit agarioskins.com
I have been eating all the small pellets, why am I not getting bigger?
All cells in the game lose mass over time in proportional to how big they are. The bigger your cell, the more mass you lose every second. When you start to notice that you are bigger than most other players, concentrate on absorbing them instead of eating the pelllets, which is inefficient compared to killing other players.
