What is Slither.io?
Slither.io is a multiplayer online game where players control a snake-like creature that grows by absorbing resources on the map. Other characters wander the map simultaneously, and the unlucky players who collide with other users will die, leaving an enormous food trail behind for other invertebrates to scoop up and grow.
What happens when you die in Slither.io?
When players die in Slither.io, they'll have to restart the game as a tiny snake, climbing their way up to size again by tracking down more orbs and food as they scuttle along the ground.
