A focused physics-game catalog
PhyFun is an instant-play arcade dedicated to games where physical behavior matters to the challenge: aim a trajectory, manage momentum, balance an object, stack structures, drive through terrain, or use collisions to solve a puzzle.
The wider legacy library is still preserved for old bookmarks and direct links, but it is excluded from the homepage, search, categories, topics, recommendations, and sitemap unless its ID is present in the reviewed physics catalog.
