Insights from the gaming industry
A browser game is a video game that is played over the Internet using a web browser. Browser games can be run using standard web technologies or browser plug-ins. The creation of such games usually involves use of standard web technologies as a frontend and other technologies to provide a backend. Browser games include all video game genres and can be single-player or multiplayer. Browser games are also portable and can be played on multiple different devices, web browsers, and operating systems.
Browser games come in many genres and themes that appeal to both regular and casual players. Multiple browser games have developed beyond the online platform to become large titles or franchises sold physically in stores, or in online marketplaces like Steam or XBLA. Some notable titles are Alien Hominid, Bejeweled, Bloons, Club Penguin, Meat Boy, itch.io, and VVVVVV.
