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.
