A game that runs right inside a web browser on a phone or computer by opening a link, with nothing to download or install from a store.
A browser game is a web page that behaves like a game. The player opens the link and it starts within seconds, with touch on a phone and the keyboard on a computer. There is no app store, no review to wait for and no space taken on the device. The trade-off is that it must stay light, and it does not appear in the app stores.
Its strength is how easily it spreads: one link in WhatsApp or on a shop's social account reaches anyone. That makes it a good fit for marketing campaign games, classroom learning games and testing an idea before investing in it. In Fanann you describe the game, then publish it as a link anyone can play on a phone or computer, with touch controls. Publishing to app stores or game platforms is not part of that. Practical tip: keep a round short, a minute or two, and make the play again button obvious. Link players try quickly and leave quickly.
