A browser game is a video game that is played on a web browser. It is distinct from other video and computer games in that it typically doesn't require any client-side software to be installed, apart from the web browser. There are games that rely solely on client-side technologies such as JavaScript or common plugins such as Java or Flash Player, whereas some employ server-side scripting. The latter case consists typically of (massive) multiplayer games, whereas the client-side games are typically single-player games. A game played in a browser is often called a browser-based game.
