browsergame

A browser game, or browsergame, is a video game that runs directly in a web browser without requiring installation of software other than the browser itself. It is designed to be accessible on multiple devices and platforms, provided a compatible browser is available.

Modern browser games are typically built with HTML5, JavaScript, and related web technologies, using Canvas or WebGL for graphics and WebSockets or asynchronous requests for server communication. They usually depend on a server component to manage multiplayer interactions, persistent world state, and updates, while the client renders graphics and handles input. Earlier generations relied on plugins such as Flash or Java applets, but these have largely been phased out in favor of standards-based approaches.

Browser games cover a range of genres, including strategy, role-playing, card games, puzzles, and casual arcade titles. Many are multiplayer online games with persistent universes or competitive ladders, and are frequently monetized as free-to-play with microtransactions, advertisements, or optional subscriptions. The browser-based model emphasizes ease of access and quick starts, often with social features such as guilds, leaderboards, and in-browser chat.

The browser game market grew in the 2000s with titles like Travian and Ikariam and platforms that aggregated games from independent developers. The rise of social networks and mobile-friendly HTML5 reduced barriers to distribution, while new engines and tooling improved cross-platform performance on desktops, tablets, and smartphones. While some browser games retain a classic isometric or tile-based feel, others push more advanced client-side rendering.

The browser game model is used as a gateway to larger online experiences and has influenced casual gaming by lowering barriers to entry. Limitations include dependence on browser compatibility and internet connection, performance variability, and evolving browser security standards.
