Since starting off as a web-based game before gaining popularity on mobile devices, Slither.io has enabled codes for free special skins to use on your slithering character.
There are no exact definitions for what exactly an IO game is, but many consider that as long as it is free to play, browser-based, multiplayer, and has minimalist graphics, it fits the bill. With this list from Toms Guide, we can see there are quite a few games based on this style with both computer browser and mobile device options.
One of the most popular of these is slither.io, thanks to its extensive list of free-to-use codes for character skins that seem to hardly ever become inactive.
What do Slither.io codes give you?
Slither codes give you special cosmetics to decorate your character with, usually consisting of a headpiece, glasses, and a special hairstyle.
How do you redeem Slither.io codes?
When you launch the game on your mobile device of choice, you will be met with an option in the top-right of your screen that is labeled ‘Enter Code.’ Unfortunately at the time of writing, the slither.io website does not allow you to redeem these free codes.

All working Slither.io codes
The currently active list of free Slither.io codes is updated rather infrequently. As a trade-off for constantly available free items, the developer doesn’t add to this list very often.
