Snakes are the playable characters in Slither.io.
Players start as very small snakes that must eat the pellets on the ground to grow bigger and longer.
Players can press either left mouse button or right mouse button for a quick burst of speed, but this will slightly decreased their snake’s size and length, and it will also leave a trail of pellets behind them.
If a snake hits the tail of another snake they will die and it will be game over for that player. A dead snake will leave pellets where they died, that other players can eat.
There are a several skins that players can use for their snake. By default, Players will use one of the first 9 skins at random. One can unlock access to the other skins along with the ability to select a skin in particular by sharing the game on a social platform from the front page.
