Agar io was the first io games. It was made by Matheus Valadares in 2015, and the internet forum 4chan helped it become very famous. The game is all about cells that grow when they eat agar and eat other players. A few months after the game came out, Miniclip bought it, and a new type of game based on the simple io name extension began to take shape. 

The games after Agar io focused on the growth features that made it so popular, making it clear that io is not just a domain extension but also a genre. One of these games was Worms Zone, just like Worms but with snakes instead of worms. There are now many grow games like Snake io and Wormate that take this fast-paced survival idea even further.

IO games: How to Play

Many io games are about survival, where you must eat food and kill other players to make your character stronger. Doing this over and over again will get you to the top of the list. Most games by IO have:

A big online multiplayer area with a scoreboard for competition.

Simple rules that make it easy for anyone to play.

Players who eat food and sometimes other players to get bigger.

Most of the time, it's a "survival of the fittest" free-for-all, but sometimes you can play with other people.
