Join us in today's video of the MOST ADDICTIVE GAME EVER EPISODE 119 - Agario or Agar.io. Today we played some more Mitos.is and we tried out the new soccer mode. |--| 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. People in the video:.
