Agar.io
PLAY IO Games are a genre of free realtime multiplayer online games that you can play in your browser without needing to install anything or create an account. The first io game was agar.io. IO is a domain extension which stands for "Indian Ocean" but it is a favored domain extension by game developers because it also stands for "in / out." HISTORY OF IO GAMES The io game genre all began with the release of an insanely addicting game called agar.io (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 a very interesting style. Unlike most browser games of the past, it was designed to be played in a full-screen 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 SUCC
