Slither.io's browser version was ranked by Alexa as one of the 1,000 most visited sites in July 2016, while the iOS version ranked first in the most downloaded apps on the App Store. A mobile version of the game for Android was released on March 27, 2016. The reception of the game was positive, with reviewers praising its appearance and customization but criticizing it for its low replay value and the high price users were required to pay to remove advertisements (although as of 2026, most versions of the game no longer show them).

Gameplay
The objective of the game is to control a snake, also known as "slithers", around a wide area and eat pellets, defeating and consuming other players to gain mass to grow the largest and longest in the game. Once players are spawned into the virtual world, their avatar remains in constant motion. If the player's snake's head collides with another slither's body, the player will die. The defeated avatar's body turns into bright, larger shining pellets for other players to consume.
These pellets that remain from "death" of an avatar will correspond to the color of the avatar itself, and are both brighter and bigger than "normal" pellets, which spawn naturally throughout the world. Normal pellets do not give as much mass as pellets dropped from other snakes. "Chase" pellets will appear individually in various places of the world and can be obtained by boosting; when eaten, they give a greater amount of mass than pellets dropped by other snakes. Chase pellets avoid snakes and flee when they draw near.
