What is Slither.io?

Slither.io is a free multiplayer snake game created by Steve Howse and released in 2016. It plays in any web browser and also has mobile apps. Every player is a snake in one big arena: you eat the orbs scattered around the map to get longer, you can hold the boost button to speed up at the cost of some length, and you are eliminated the moment your head touches another snake. The trick that made it famous is that size is not safety — a tiny snake can take down the longest one on the leaderboard by cutting across its path at the right moment.

What makes a game "like Slither.io"

The core ingredients are simple: a snake or worm that grows as it eats, a shared arena full of rivals, and a head-first collision rule where whoever runs into a body loses. The best alternatives keep that loop and add their own spin — a battle-royale ring, numbered blocks you merge as you grow, color-matching, or a more cartoonish 3D arena. Some are true online multiplayer, others fill the arena with computer-controlled snakes so a round starts instantly. If you just want the original single-player Snake — eat, grow, do not hit your own tail — that is here too.
