Online games refer to video games that are played over some form of computer network, most commonly the Internet. The expansion of online gaming has reflected the overall expansion of computer networks from small local networks to the Internet and the growth of Internet access itself. Online games can range from simple text based games to games incorporating complex graphics and virtual worlds populated by many players simultaneously. Many online games have associated online communities, making online games a form of social activity beyond single player games.

Early online games Online games started in the 1980s with MUDs, simple multiplayer text-based games, often played on a BBS using a modem. These games were frequently based on fantasy settings, using rules similar to those in the tabletop role-playing game Dungeons & Dragons. Other styles of games, such as chess, Scrabble clones, and other board games were available. Since continuous connectivity was often expensive as access was frequently charged on a per-minute basis, some games were set up as play-by-email games.

First-person shooter games During the 1990s, online games started to move from a wide variety of LAN protocols (such as IPX) and onto the Internet using the TCP/IP protocol. Doom popularized the concept of deathmatch, where multiple players battle each other head-to-head, as a new form of online game. Since Doom, most first-person shooter games contain online components to allow deathmatch/arena style play.

Real-time strategy games Early real-time strategy games often allowed multiplayer play over a modem or local network. As the Internet started to grow during the 1990s, software was developed that would allow players to tunnel the LAN protocols used by the games over the Internet. By the late 1990s, most RTS games had native Internet support, allowing players from all over the globe to play with each other. Services were created to allow players to be automatically matched against another player wishing to play.

Browser games Main article: Browser game As the World Wide Web developed and browsers became more sophisticated, people started creating browser games that used a web browser as a client. Simple single player games were made that could be played using a web browser via HTML and HTML scripting technologies (most commonly JavaScript, ASP, PHP, and MySQL). More complicated games would contact a web server to allow a multiplayer gaming environment.
The development of web-based graphics technologies such as Flash and Java allowed browser games to become more complex. These games, also known by their related technology as "Flash games" or "Java games", became increasingly popular. Many games originally released in the 1980s, such as Pac-Man and Frogger, were recreated as games that could be played using the Flash plugin on a webpage. Most browser games have limited multiplayer play, often being single player games with a high score list shared amongst all players.
Browser-based pet games are also very popular amongst the younger generation of online gamers. These games range from gigantic games with millions of users, such as Neopets, to smaller and more community-based pet games.
More recent browser-based games use web technologies like AJAX to make more complicated multiplayer interactions possible.

Massively multiplayer online games Massively multiplayer online games were made possible with the growth of broadband Internet access in many developed countries, using the Internet to allow hundreds of thousands of players to play the same game together.
