The acrylic maze piece must be removed, and the three key pieces are simultaneously manipulated to achieve the goal.

The Buffalo Nickel Puzzle is based on the Nine-and-a-half-Moves puzzle by M. Oskar van Deventer. It is composed of just three pieces that fit together in such a way to hide a secret compartment. Although the three pieces are flat and lie in a single plane, it takes a remarkable 9 1/2 moves to solve.Originally made by George Miller for IPP 20 in Los Angeles, I believe this was subsequently reproduced by Bits & Pieces and is what is offered here.It is basically a two dimensional three pi...

Remove the ring from the bolt.

ResQ is a unique Sequential Discovery Puzzle based on Boucher's brilliant Visitor Q. We took the original design and modified it by adding additional goals, tools, and tricks. ResQ is the result of nearly three months of prototyping and features previously unseen concepts and hardware. The brilliance of Boucher's VQ design is in the depth of possible movements and states the puzzle can be in. Visitor Q is very much like a maze; you find configurations that won't allow you to progress and mus...

Wil Strijbos made several bolt puzzles, including this design.The goal is to remove the ring (see last picture, no spoiler).This design is easily recognised because of the nipple in the end of the bolt.This is WS #8 according to Haubrichs catalog of bolt and nut puzzles.This copy has a few rusty patches, in the thread and on the pin that extends from the nut.This does not affect the puzzle fuctionality.

Wil Strijbos made several bolt puzzles, including this design.The goal is to remove the ring (see last picture, no spoiler).This design is called "low number bolt" even though it is #9 according to Haubrichs catalog of bolt and nut puzzles.During the solve, a part of the inside can be seen and is rusty, this is not visible in the assembled state and does not affect the solve.

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...

A reproduction from a turn of the century promotional piece during the presidential election of 1896.This puzzle design is almost equal to Hanayama's cast laby puzzle, produced around 1996.The main differences are the text and the colour.It comes with a solution sheet that also describes the background of the design.The goal is to navigate the double sided maze on one of the two rings and ultimately seperate the two parts.

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.
