The io games trend began in April 2015 with the release of Agar.io, a shared online game that was based on how microbes behave. In Agari.io, players are in a situation where they must eat or be eaten. They move around a map to find food and grow bigger. Eventually, they get big enough to start eating the smaller cells of other players. But they have to keep an eye out for bigger players who might try to hurt them.

The first thing that made Agar.io famous was how easy it was to play but how intense it was. But the game didn't go popular until well-known Twitch and YouTube gamers started playing it.

IO Game became hot

PewDiePie, who is well-known on the Internet, fell in love with the game. He shared many Agar.io videos with his 100 million YouTube followers. Some of the videos got more than 8 million views.

This was the thing that got the IO game going. The word "IO games" became the most-searched gaming term in the U.S. a year after Agar.io came out, and more and more online games started to register IO domains. The main reason these games are still so popular is that anyone can play them. You can play them for free with any computer browser. IO games can be played on almost any gadget, old or new, as long as it has a basic Internet connection. Large production houses have joined the industry and are making high-quality, interesting games in a variety of styles for a community of millions of players that keeps growing.

PewDiePie noticed that these simple games are also popular forms of passive entertainment, with billions of views per year on YouTube and Twitch. Some of the most popular games make more than $100,000 every day from premium material and advertising. Everyone in the creative gaming community has a stake in the success of IO games, from small, independent makers to large, well-known studios. This can only be good for players, who can expect to keep getting high-quality, fun games for free. As long as this continues, these games will continue to reach more people.
