The Rise of IO Games

The first .io game was Agar.io. It was developed by Matheus Valadares in 2015 and gained significant popularity through the internet forum 4chan. The game revolves around cells that grow by eating agar and consuming other players. A few months after its release, the game was acquired by Miniclip, and a new game genre started to emerge based around the humble .io domain extension. 

The games that followed were focused on the growth mechanics that made Agar.io so popular, strengthening the idea of .io as a genre, not just a domain extension. Worms Zone was one of those games, with the same simple yet addictive concept but with snakes. There are now many grow games like Snake.io and Wormate, taking this fast-paced survival concept further.

How to Play .IO Games

Many .io games are based on survival - growing your character by consuming food and slaying other players. Reach the top of the leaderboard by doing this repeatedly until you're the biggest! Most IO games feature:

  • A large online multiplayer arena with a competitive leaderboard.
  • Simple mechanics that make gameplay possible for anyone.
  • Players that consume food, and often other players, to grow bigger.
  • Mostly a ‘survival of the fittest’ free-for-all, sometimes with cooperative gameplay.

What are .io Games?

IO games are real-time online games you can play in your web browser for free. The most common theme among .io games is online multiplayer. Besides that, these games are mostly based on the domain extension .io, which stands for ‘Indian Ocean.’ The top level domain extension is popular with software engineers since IO is short for 'Input / Output', a common term in computing.
