Show HN: Fable52.games – Play and inspect Fable 5.2 single-file HTML games

Fable52.games is an unofficial community arcade showcasing 32 browser games built autonomously with Claude Fable 5.2, generally from a single detailed prompt. Visitors can play games, read their prompts, and inspect their code, making the collection both a game library and a demonstration of what an AI coding agent can produce. Its range includes first-person shooters, exploration games, simulations, racing, puzzles, horror, and multiplayer projects. Featured game Saltline is a 3D shooter set in a rainy container port; its page says it took eight hours to build and fits in a 1.4 MB file with no external assets. Other examples include a 128 KB shooter built in 41 minutes, an underwater exploration game, and a Chinese-localized remix of Saltline.

The collection emphasizes portability and transparency: many games package their markup, styles, code, graphics, and synthesized audio in one HTML file that can run in a modern browser, even offline. Three-dimensional titles commonly use WebGL and Three.js, while procedural generation supplies levels and assets. Each game can be played and downloaded, and a source inspector lets visitors examine or modify the implementation; prompt details and controls are also available where provided. The site says hosted games run in sandboxed frames to restrict access to site data, while creator-hosted games remain isolated on their own origins. Anyone can submit a game without an account, subject to review. The arcade is not affiliated with Anthropic, and remixers are asked to respect creators’ licenses and provide credit.
