Internet gamegames that are played online via the Internet. They are distinct from video and computer games in that they are normally platform independent, relying solely on client-side technologies (normally called 'plugins'). Normally all that is required to play Internet games are a web browser and the appropriate plugin (normally available for free via the plugin maker's website). A game played in a browser is often called a browser-based game.
However, there are also server-side games which do not require plugins and process the data on the game server instead of the player's computer. These games are typically not as pulchritudinous as client-side based games, but make up for that in advanced functionality, particularly because it is easier to implement multiplayer capabilities. BattleMaster is an example server-side game.
Hybrids of server- and client-side games also exist.
