A browser game is a computer game that is played over the Internet using a web browser. Browser games can be run using standard web technologies or browser plug-ins. The creation of such games usually involves use of standard web technologies as a frontend and other technologies to provide a backend. Browser games include all video game genres and can be single-player or multiplayer. Browser games are also portable and can be played on multiple different devices, web browsers and operating systems. 
Browser games come in many genres and themes that appeal to both regular and casual players.
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.
Browser games can take advantage of different technologies in order to function.
Browser plug-ins can be used to provide game technologies after being installed by the user.
