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. This set the framework for many of the other .io games that would hit the web in the months to come.

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 in-game 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, they are either competitive or cooperative.

Just take a good look at slitherio. The basic game idea is very simple and the controls are very intuitive. It has a very nostalgic feel for older players that grew up with games like snake. It's easy to play for anyone with little to no experience, but difficult to master. That makes it ideal because people can jump in and get hooked quickly. Not to mention the graphics are very captivating.

Why Create Games?

To have fun! I always played games and read comic books so I decided to become a programmer and make games for fun.
