A browser game is a video game that is played via the World Wide Web using a web browser. These games span all genres and can be single-player or multi-player. They are usually free-to-play. 
            Some browser games are also available in other forms: as a mobile app, a PC game, or on a console. For users, the advantage of the browser version is not having to install the game; the browser automatically downloads the necessary content from the game's website. However, the browser version may have fewer features or inferior graphics compared to the others, which are usually native apps. 
            The front end of a browser game is what runs in the user's browser. It is implemented with the standard web technologies of HTML, CSS, JavaScript, and WebAssembly. In addition, WebGL enables more sophisticated graphics. On the back end, numerous server technologies can be used. 
            In the past, many games were created with Adobe Flash, but they can no longer be played in the major browsers. Some of these games have been preserved in a dedicated app.
