Checked for new codes!
In Slither IO, size does matter, as your only goal is to become the biggest player of them all. Slither IO is a casual mobile and web browser-based game developed by Lowtech Studios where players control a snake, or a worm-like character, that slithers around and gathers colorful pellets to grow in size.
You can get killed if you run into another player, but they can die in the same way as well, leaving more food for you. And that’s the beginning of the endless journey of online players trying to trap others to kill and consume their pellets. The bigger you are, the higher your score. But trying to become the biggest is not the only fun aspect of the game.

How to download the mod
You can just google search “Slither io mod APK” and you will get aplenty of websites that host a download link for the same.
The black skin code won’t work can you please help
Hi Bob,
To get the black skin code working you need the modded APK for the game. As mentioned in the sub-title, they all are mod codes. So, once you have installed the modded APK, use the black skin code and it will work fine.

Hritwik Raj
What is the moded APK?
Modded APK is a community created thing.. It generally means, modified versions of the original game. We have normal APKs(the original one) that players can download from the google play store or any other secure online storefronts. And, then we have the mod version of the same game with additional features, that are found on the 3rd party community website.
can you tell us the download then? lmao i need it rn
We cannot share the third party download link, but if you search the keyword “Slither.io MOD APK v1.6.2” you will get the modded APK from a website called androidhackers.
