Common questions
Is Sero.io like Agar.io?
Yes. You start as a small cell, eat food and smaller players and split to eat them. If you have played Agar.io, Gota.io or Senpa.io you already know how to play. Sero.io is made for phones and adds more modes, replays, skins and weekly prizes.
Is the game free?
Yes, and there are no ads. Sero Gold and Platinum are optional and only give cosmetic and convenience perks like a custom username font/color and cell color.
Can I play on PC or iPhone?
Not yet, Sero.io is on Android for now. A browser version is coming. Join the Discord to hear about it first.
Can I play with friends?
Yes. Add each other in-game to appear in your friendlists and join the same server. You can also save a replay and send it to each other.
