Hi! Welcome to
The .io Games List
The io Games List is the biggest list of online multiplayer web and mobile games. What is an .io game? Well, it’s basically that. The first .io games were cursors.io and voar.io, the latter now offline. But the real .io trend began with agar.io, which was followed by other great games like slither.io and diep.io.
Most .io games are based in older single player games, and what makes them great are the following principles: Easy to get into (generally no download required), simple controls, massive online and the possibility to became stronger than the rest.
Today, the most popular .io games at the moment are Agar.io, Slither.io and Diep.io. I created this site to have all the best io games in one place. Bookmark this website using Ctrl+D because we will add new games as soon as we can!
