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.
An online game is a video game that is either partially or primarily played through the Internet or another computer network. Online games are ubiquitous on modern gaming platforms, including PCs, consoles and mobile devices, and span many genres, including first-person shooters, strategy games and massively multiplayer online role-playing games (MMORPGs).
The history of online games dates back to the early days of packet-based computer networking in the 1970s, An early example of online games are MUDs, including the first, MUD1, which was created in 1978 and originally confined to an internal network before becoming connected to ARPANet in 1980. Commercial games followed in the next decade, with Islands of Kesmai, the first commercial role-playing game, debuting in 1984, as well as more graphical games, such as the flight simulator Air Warrior, released in 1987. The rapid availability of the Internet in the 1990s led to an expansion of online games, with notable titles including Quakeworld (1996), Ultima Online (1997), Starcraft (1998), and Counter-Strike (1999). Video game consoles also began to receive networking features, such as the PlayStation 2 (2000) and the Xbox (2001). Following improvements in connection speeds, more recent developments include the popularization of new genres, such as social games, and new platforms, such as mobile games.
