Wil Strijbos made several bolt puzzles, including this design.The goal is to remove the ring (see last picture, no spoiler).This design is referred to as #2 according to Haubrichs catalog of bolt and nut puzzles.This is a later reproduction by Wil, produced around 2016, with one end of the pin made from brass.It has a few very minor dents on the outside, which is common for this type of puzzle (see pictures).

Unsafe Deposit and Bolt Action have been considered by the MPD to be gateway puzzles into the Sequential Discovery genre for good reasons. They're cheap and easy to get while also being excellent puzzles with tools and quirks to be discovered!An enjoyable puzzle for sure, but I need to clear out some space in my collection (not that selling these two tiny puzzles will net me much room). Also, they're being sold as a bundle, because if you have one then you need to own the other one.They also hav...

Very fun and well-made popular take apart puzzle from Jon Keegan.

Topless Box had me confounded for a VERY long time. The 'aha' moment for this one is why it is so sought after. Here is the description from the website:Topless Box by Eric Fuller was my contribution to the legendary Apothecary Puzzle Chest. Topless is an unusual challenge; with two lids and no top, how can it be opened? The solution is tricky and will surprise you. Originally released in 2012, we found strong demand with our re-release last year and decided to make one more batch for newer col...

An extremely difficult puzzle. Some may say - too difficult.This Black and Gold version is pretty rare as far as I know.It comes with some encrypted clues so contact me if you win and I'll send them to you.

The goal of the Copernisis is to open the key chamber.But in order to do that you must solve some complex riddles.Sent in original leather box packaging.

Aligarh produced several trick locks, including this '10 lever' design.It has the usual rusty / worn touch & feel, but the mechanism works flawlessly.It comes with two equal keys, in a pink cardboard box, which shows clear signs of age and wear & tear.That may add to the rustic image of the lock.It also comes with a handwritten (not sure by whom)  solution.This is not a very difficult design, it has two main tricks and requires 3 steps to open.

Trinity Infinity from Doug Engel (Bits and Pieces)Three-piece metal take apart (or disentanglement) puzzle.  The goal is to take the three pieces apart and reassemble again.  I found it fairly easy to take apart, but a little more challenging to put back together.  A review can be found here: http://mypuzzlecollection.blogspot.com/2012/02/trinity-infinity.htmlIt has been solved several times, and is in used condition.  There is minor but noticeable wear on the pieces.  Some of the sm...

Great Collision from Doug Engel (Bits and Pieces)Beautiful looking 3-piece metal take apart puzzle.  The goal is to free the plastic ball in the center by taking apart the 3 metal pieces.  I thought the solution (and reassembly) wasn’t too difficult.  I enjoyed displaying it with my metal puzzle collection though, especially given its size, weight, and theme.The puzzle is in great condition, with no major scratches or marks.  Scuff marks will develop on the black coating as the pu...

This is one of the earliest copies of Jerry McFarland's wonderful Quadlock I, a "squashed" cube made of 19 burr sticks, featuring a 4-piece locking system that sets this apart from typical interlocking cubes (and is why I classified it as a Take-Apart rather than just Interlocking). The first phase of its solution feels like lock-picking in some ways, with the interlocking disassembly aspect of the puzzle following. Reassembly is quite tricky but follows a clear logic (again, feeling more ...

A vibrant piece beautifully crafter by Brian Menold - Moves: 19.4.6.4What Brian has to say about Red Poppy: Another of Alexanders designs is this colorful challenge. The center of the poppy is captive in the frame and you must remove and reinsert the four surrounding petals of the poppy. I know the name is Red Poppy but I only had a limited amount of vivid redheart and I did have some nice Yellowheart, so I made a few of those to throw into the mix. Since the pieces can all freely rotate when i...
