Pennytentiary

Pennytentiary was our first coin release puzzle and the culmination of months of design and prototyping. To solve this sequential discovery puzzle, you must release the penny trapped inside.

Pennytentiary's complexity and depth rival that of our trickiest puzzle boxes. The solution is very challenging, with multiple "aha" moments to be found. Success relies upon the discovery and use of various tools to execute more than dozen confounding moves. No force, tapping, banging, or dexterity is required. Pennytentiary ships in an unsolved configuration.

This puzzle contains small parts and should be kept away from children. We recommend exploring Pennytentiary on a flat surface.

Precision wood puzzles can be damaged by environmental changes. Please read the Caring for Wood Puzzles guide to ensure proper fit and operation. We recommend occasional polishing with Renaissance Wax to keep wood puzzles in top condition.
