What are IO Games?

IO games are multiplayer games that contain the word "io" within the game title. The game is typically hosted on a .io domain name. The .io is a top-level domain for the British Indian Ocean territory, however it is increasingly being used as a generic extension, for new startups and real-time games. These games feature battles between players in a massive arena where players have to compete against each other to gain points. The top played .IO games are Bonk.io and Slither.io.

Background of .IO Games

The first IO game ever created was Agar.io back in 2015. It was released on a large internet forum by Brazilian developer Matheus Valadares and later acquired by MiniClip. This .io game features simple gameplay mechanics where you control a single colored cell and try to eat all smaller cells to become bigger. Later in 2016, Matheus also released Diep.io, which is a tank game where you destroy other players to level up. 

The success of Agar.io interested other developers to create similar real-time io games. In 2016, United States based developer Steven Howse, released the game Slither.io. In this game, your goal is to simply survive and become the largest and longest snake, by sliding around and eating glowing orbs. The gameplay is similar to the classic snake game with better graphics and the ability to play with others in real-time.

Over the years, several other hit .io games were released, such as Bonk.io, Wormax.io, Paper.io, Zombs.io, Tankwars.io, Skribbl.io, Hole.io and many others. We included them all on Arcade Spot!
