Pennytentiary was one of Eric’s 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.
