Agar.io is a massively multiplayer action game designed by Matheus Valadares. Players control a cell in a map representing a petri dish; the goal is to gain as much mass as possible by swallowing smaller cells without being swallowed by bigger ones.

The Bare Essentials

    There are two types of movements in Agario: Proactive pathing, and reactive pathing. The larger you are, the easier it is to make proactive movements. On the contrary, factors like virus, map borders, and teams can force even the largest cell into a reactionary path. Proactive movements can be many, many, things. I will describe this in detail at a later point.

    Automatically generated mass by the map is something you need to passively collect through all stages of the game. Often times it is easier to collect free mass than it is to be an aggressor. Keep in mind once you reach about 1000-1500 mass you will only sustain your size this way. This is due to the natural decay of mass all players exhibit.

    There are five cell sizes relative to your own: With enough experience, you will be able to actively determine the state of all cells within view.

    Hostile - can split kill you
    Threat - cannot split kill you, but can consume you
    Neutral
    Prey - consumed if touched, cannot split kill
    Victim - a free split kill

    Viruses can be your best friend or your worst enemy. Here are some general tips:

    It takes 7 feed for an unfed virus to duplicate.
    When a virus duplicates, the copy moves in the direction of the last feed it received.
    A fed virus will be slightly larger.
    If you are in 16 pieces you will be able to consume viruses with no repercussions.
    A skilled player will punish you heavily for using viruses in an interaction with them.
    Viruses bounce off walls.

Have a go fun as hell there is an option to register or play as guest   i use FH|Apoc  and play on mostly the Usa / uk / aus servers....

SpaceBar = Split
W or R = feed

This game is so addicting and I'm not sure why. Got to agree with you Apoc. I usually go by Blah when I'm playing this.

yeah its basic but damn its fun...   

My son and daughter won't stop playing this game lol, especially my daughter. She's 13 and thinks it's just the best since sliced bread. I played it a bit to see what all the fuss was on about and it didn't appeal to me, but to each there own lol. Fun little game. Kinda analogous for real life; soon as you're on top, you're a target lol, then once cut down to nothing, start over again - it's capitalism in game form.
