What is Slither.io?

Slither.io is a popular browser-based multiplayer game released in 2016. In Slither.io, players control a snake avatar which grows longer as it consumes multicolored glowing orbs scattered across the map. The snake grows with each orb consumed, allowing it to wrap around and consume more orbs and other smaller snakes. The goal is to grow the longest snake while avoiding running into the sides of the game screen or other snakes, which will kill your snake.

As a player's snake gets bigger, it becomes harder to maneuver around the screen and avoid other snakes or walls. This adds to the challenge and intensity of the gameplay. The neon graphics and simple concept made Slither.io widely accessible as a casual web game. While the core gameplay is straightforward, mastering Slither.io requires strategy in navigating your growing snake and predicting where your opponents are headed.

Slither.io grew rapidly in popularity after its initial launch, in part because it was free to access and playable on any browser. At its peak, it amassed over a million concurrent players per day competing to top the leaderboards. The success of Slither.io ushered in several .io game clones with similar massively-multiplayer mechanics.
