Overview

Slither.io is an online multiplayer action game in which every player steers a growing snake-like slither through a shared arena. The aim is to grow as long as possible and become the longest slither of the day. Slither.io runs in a web browser and as an app for iPhone, iPad and Apple Vision from Lowtech Studios. The app is free to play, with an in-app purchase that removes ads.

How a round of Slither.io is decided

Every match is a contest of position rather than size alone. A slither dies the moment its head touches another player’s body. It explodes and leaves its remains in the arena for other players to eat. Eating the remains makes them longer. The same rule works in reverse. A player who cuts across a rival’s path and makes its head run into the player’s body collects the remains.

This is why a short slither still has a real chance against a much longer one. Length makes a slither a bigger obstacle and a bigger prize, but a well-timed swerve in front of a large opponent can end its run. The app sums up the exchange as “boop or be booped”. It also keeps a boop counter so each player can see how many rivals they have taken out.

The daily champion and the victory message

Slither.io tracks the longest slither of the day across its players. Slither.io names the player who takes that title the new champion. It asks them to write a victory message that every other player in the game will see. The message gives the daily record a visible reward beyond the length itself.

Choosing a server

Before joining, players can pick the server they connect to instead of being placed automatically. The app also includes a map.

Skins, cosmetics and building your own slither

Players choose the look of their slither on the start screen. Players can cycle through ready-made skins and add cosmetic items to their slither. They can also use the skin builder to create a pattern of their own instead of picking a preset. The app adds an option to fade the player’s displayed name. The app has also added new backgrounds.

Controls and display options in the app

On iPhone and iPad, Slither.io offers more than one control mode, including arrow-based controls. It also has a settings screen for adjusting how steering responds. The app supports play in any screen orientation and has a look-ahead setting.

The browser version has a high-quality graphics toggle on its start screen. The app also includes music and sound effects, and it supports live events alongside regular online play.
