You are playing gulper.io
Gulper.io is an awesome multiplayer snake game that takes inspiration from Slither.io. You must take control of a small glowing worm and try to grow bigger so that you can destroy the other worms on the playing field.
You can grow bigger by gulping the glowing dots scattered around the map. You must move quickly and keep an eye out for enemies approaching as they will try and catch you out. Destroy your enemies by trapping them and making them slither into your own body. Can you become the largest glow worm?
