History of .io games
The very first .io game was Agar.io. It was created in 2015 by Matheus Valadares, a Brazilian software developer, and released on the internet forum 4chan. It became an overnight sensation, amassing millions of players. The game features cells which grow by eating agar or other players, and which can be split. Agar.io was acquired by Miniclip a few months after its original release.
Agar.io’s success inspired other developers to build similar browser-based real-time multiplayer games. Steven Howse, a developer from Michigan, USA, released Slither.io in March 2016. In that game, players return to the world of classic Snake in an improved, multiplayer-enabled version. Players run around the arena eating cool glowing orbs to grow their snakes. All it takes to die is one collision with another player (or yourself). The game reached its peak in July 2016, earning, in that period, an income of over $100,000 dollar per day (according to the Wall Street Journal).
Diep.io was released in April 2016 by Matheus Valadares. The game features various tanks which can be leveled up by destroying other players. The game was received generally positively (albeit not as positively as Agar.io) and proceeded to be a hit.
These 3 games inspired new developers to create many more .io games, e.g. Bonk.io, Wormax.io, Wormate.io, Zombs.io, Paper.io, Brutes.io, Spinz.io, and so forth. They became too much to remember, which is why we collected them here on this web!
