With a game as popular as Slither.io, it is no surprise that bots have been made. However, no one could suspect the technological advancements stemming from a simple browser game. The bots designed for Slither.io have superior Artificial Intelligence and threat detection algorithms while, surprisingly, not cheating at all. They are very easy to suspect and you can suspect a bot by looking the way it moves. Most bots go for the small cells, you can see them moving more abnormally than a usual snake you see in-game. This makes these bots a very easy target. They don't break any game mechanics, nor do they claim any superior advantage via code. It's entirely via the use of AI that they stand a chance at all. Popular examples of these bots are the "Slither jLynx Bot " by ErmiyaEskandary and the "NotReallyABot".
This type of bot is cheating and we do not advise you to use it. If you do use a Feeder Bot you are at risk of being IP-banned from Slither.io.
Feeder Bots usually consist of 7 to 10 bots in one server. One person installs a program in their browser which will track which Slither.io server they go into and brings the bots with them. These bots will then follow the mouse cursor of whomever controls them and are used to feed them, Hence the name "Feeder Bots". Every time a bot is eaten they will immediately respawn and go back to the mouse cursor.
This type of bot has recently become popularized and is technically cheating as it is unfair to other players. Once a player leaves the server, all of the bots will go to the center of the map endlessly being eaten and respawning until the server closes.
Be careful! Some bots may contain a virus, or more than one.
