Why it’s interesting
Sunjing turns a wooden mechanism into a small interactive workshop. Rotate the six-piece lock, select a piece and work out which direction will free it. Two Huarong Dao sliding-block layouts offer a different kind of spatial puzzle.
MartinDelophy initiated and submitted the project. Its public creation record describes iterative Codex work on the interface, 3D scene, rules and interactions. The exact model identity remains unconfirmed, so we do not attribute it to a particular model. The lock is a teaching adaptation, not a verified historical replica.
How to try it
Use the numbered controls to select a piece, then try an extraction direction. Hints and undo support experimentation. We checked that a hint selected a movable piece and extraction changed the solved count from zero to one. On a sliding-block board, select a block and use the direction controls. The interface is in Chinese.
Requirements and sources
Free browser play without an account or API key; WebGL 2 is required. Current puzzle progress is stored in this browser, not in a cloud account. Switching levels starts a new puzzle. The creation record begins on September 5, 2026. No blanket MIT license is claimed for the game-specific source; this guide links to the original rather than redistributing it.
