PuzzleSmith

PuzzleSmith is an adventure game puzzle validator for game developers.

Define rooms, one-way links with lock requirements, items, flags, puzzle actions, and endings — then run real reachability analysis (breadth-first search over room × inventory × flags) to prove every ending is reachable and catch soft-lock states before your players find them.

Get the shortest human-readable walkthrough for each ending, and export walkthroughs and reports. PuzzleSmith runs fully offline, locally in your browser, as a single HTML file — no installs, no servers, no sign-ups.

This is the free demo — limited to 12 rooms, 8 items, 1 ending, and Markdown export. For unlimited rooms, items, and endings, what-if analysis, and walkthrough/JSON/CSV exporters, upgrade to PuzzleSmith Pro: https://theluckyduck666.itch.io/puzzlesmith-pro
