IO Games List

History of IO Games

The io game genre all began with the release of an insanely addicting game called (which was probably inspired by another game called “Osmos”). Agario grew so fast that within months, it was already seeing several hundred thousand players worldwide. What made this io game so unique was it’s very interesting style. Unlike most browser games of the past, it was designed to be played in a fullscreen browser window, and was entirely multiplayer.

New IO Games, Rules for Success

Creating fun and successful new io games like, and is not easy. Not only do you need a new game idea, you also need to make sure your game follows these basic rules;

  • Have the player be able to hop right into a game with one click.
  • Keep it super simple to learn but difficult to master.
  • Allow the player to “scale” their authority ingame compaired to other players. (Ex. In agario you grow a lot bigger and scarier the more you eat and scale your size.)
  • And last but not least, it has to either be competitive or cooperative…

Just take a good look at slither. The basic game idea is very simple and the controls are very intuiative. Plus it has a very nostalgic feel for older players, players that grew up with games like snake. This makes it easy for anyone to play with little or no experience. But of course it takes time to become really good at it. That makes it ideal because people can jump in and get hooked quickly. Not to mention the graphics are very captivating.

Why Create the List?

After playing the first few big io games I started to search for more. But sadly I found them hard to find, there didnt seem to be any kind of list. So I decided to create my own. I included all the titles I could find and soon, users started to share new ones with me. That provided the perfect opportunity to help them gain more exposure.
On this site you will find that the games in the list have a common style and theme similar to those mentioned above. The goal? The goal of the list is to bring exposure to these .io games that are awesome but often times go unnoticed. This is due to the fact that they are all standalone games which means that unfortunately they are all hosted on seperate sites. That’s what we’re here for! So, support the games and make sure you bookmark this site (CTRL-D) We try to keep it updated with new io games every week, so make sure to check back from time to time. Have fun!
