Join us in today's video of the MOST ADDICTIVE GAME EVER EPISODE 61 - Agario or Agar.io. Today I became the BIGGEST AGARIO HERO in the world after me and deadlox grinded the zombie gamemode for a while. We got a lot of mass and started eating everyone. |--| If you haven't heard of agar.io before - it's basically an online game in which you start out as a small dot and you can eat dots to become a bigger dot. It's an online multiplayer game tho, which means that there is other players doing the same which makes it quite difficult and. addictive :D. Subscribe for daily fun.
