The great thing about this brand new age of free online games, is that old classics get revived and given an update. In this case Snake has morphed into Slitherio. A free, online multiplayer game in which you move around a map collecting glowing orbs. Every orb your pick up lets you grow a little longer. But be careful, if you ever crash into something headfirst, like your own tail, or another player, you vanish into a collection of orbs for other players to pick up. Keep moving and evading other players until you've become the biggest and strongest there is in Slitherio.
