Pennytentiary is a sequential discovery coin release puzzle
from the late great Eric Fuller of Cubicdissection. The object is to free
the penny, or should I say cent, from the “pennytentiary” it’s in. Once again Eric has cleverly hidden
the steps it takes to release the coin. A lot of puzzling in a compact package.
This puzzle has been solved twice and is in great shape.
