.io games have taken the world by storm, with countless games on the App Store charts. You have probably heard of at least one .io game, such as hole.io, slither.io, and agar.io.

.io is the Internet country code domain assigned to the British Indian Ocean Territory. This domain is administered by the Internet Computer Bureau, a company based in the U.K. It’s unclear why so many games now use this in their name. Some people believe that “.io” is used so much because it’s the quickest and easiest domain to register. However, “.io” also stands for input/output, so it may have been chosen to reflect the type of game. It also takes a boring App name and makes it more fun and memorable. For example, many people say read “agar.io” as “agar-ee-oh” instead of actually saying “agar-dot-eye-oh.”

.IO has been around since 1997, but didn’t really become popular until agar.io, came out in 2015. These .io games should be stopped, they are taking over our viral universe!

I used to play .IO all of the time. I played slither.io, surviv.io, diep.io, and so on and so forth. WHAT WAS I THINKING!? I don’t know why, but I really, really liked them. Other people at the time did too. I’ll also be doing a top 10 .IO games at the end.

Well, this is the end. So, here we go! TOP 10 BEST .IO GAMES.
