Profile Schemes

Agar.io has skins which you can currently only use in the FFA Mode.

Skins are hand drawn and purely cosmetic, they can be used by typing a certain name into the "nick" box. Each skin requires a unique name to be able to be used.

You can find a list of all the available skins here

The reddit page where you can submit your own skins can be found here
