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.

Pennytentiary Torture

I have had this little bugger in my work bag for weeks and managed only a couple of teensy moves. Finally after spending some brain time. I made a breakthrough, something I probably should have thought of weeks ago. Still not done but a lot more progress. This is great puzzle. Lots of Fun and certainly not easy. Just the way I like ‘em. C

Perfectly Pleasing Penny Puzzle

I love Pennytentiary, there's a plethora of puzzling packed into this petite package, with it's prisoner penny and perplexing pathways. Push and pull and pry, and try not to cry as the coin's captivity confounds you! - A beautiful box of layered wood, which fits nicely in the hand. The mechanical movements are magnificent in this miniature but marvellous money-maze.

Great Puzzling!

If there are copies available, pick one up! You will not be disappointed: with a lengthy and devious solve, you will be tricked, deceived, challenged and entertained while you work your way through this multi-stage sequential discovery coin release puzzle!
