Browser games are often free-to-play and do not require any client software to be installed apart from a web browser or browser plug-in. In some cases a game may be free, but charge for extra in-game features. Multiplayer browser games have an additional focus on social interaction, either between several players or on a massive scale. Due to the accessibility of browser games, they are often played in more frequent, shorter sessions compared to traditional computer games.
Since browser games run isolated from hardware in a web browser, they can run on many different operating systems without having to be ported to each platform.
