IO games are free online games you can play in real-time on your computer. Online gameplay is the thing that most io games are about. Aside from that, most of these games are built on the io domain extension, which stands for 'Indian Ocean.' Since "Input/Output," a familiar term in computing, is shortened to "IO," this top-level domain extension is popular with software engineers.
