Worm.is

Worm.is is a massively multiplayer online game developed by Freakinware Studios in 2016. The game is available on Steam, App Store and Google Play.

Worm.is is one of the many clones of Slither.io, a game where players aim to be the longest snake in the server. As described by GameSkinny, "for the time being it simply has more incentive to keep playing" and "as a clone it's one of the best of the bunch."
