Do I need to introduce this puzzle ?Very good and quite difficult puzzle. Description from Pluredo's site :This is Juno’s second sequential discovery puzzle that he initially designed to become so. The first one was Sequential Discovery Burred Box though he has also designed several puzzle boxes that have tastes of sequential discovery. This puzzle requires lots of steps, around 15 to 20 depending on how it is counted. The puzzle has an internal cavity and it is also categorized as a puzzle b...

Description from Brian :Straight4ward (designed by Laszlo Molnar)  ships unassembled Laszlo’s been at it again! Another very challenging packing puzzle from,in my opinion, one of the best at designing them! After production on these was almost complete, another solution was discovered with a rotation, however I felt that even with this added solution, this was an extremely difficult puzzle. The restricted opening alone, provides enough of a challenge for me! Try first to find the one solution...

This is notably large and sturdy for a 3D puzzle.  The object is to release the dollar bill hidden inside of the box.  Interesting mechanism.

Andrew Crowell's Turning Interlocking Cubes (TICs) revolutionized the genre.  FanaTIC is one of his classic designs: 6 pieces assemble into a 4x4x4 cube, but requires a 4.4.7.3.2 solution that includes 5 different rotations.  It's incredible.  Only solved once, and it was only undone for these photos - proving to me that disassembly is no walk in the park either.  Comes with original box.

This is not a mechanical puzzle.  It is a interconnected set of paper-and-pencil puzzles the solver must progress through to open two interior chests.This is from the now defunct Indiegogo-funded Armchair Detective Company.  The founder, Shelby Arnold, had to shut down the company after she became seriously ill.

3D Sliding BlockBy tilting and turning the box over you can make make serval dozens of sentences. Can you make 14 original proverbs? Good Luck!From the IPP17 (San Francisco August 1997).

Fallingwater Burr IPP34 excjange gift from Lambert Bright for the IPP34 in London.A really interesting burr that comes with solution (not solvable by burr tools).Very interesting and displays well.

Boron is a moderately difficult puzzle that displays like a piece of sculpture once it's solved. The 12 pieces are made with contrasting hardwoods and precision-crafted in our North Carolina workshop. Its interlocking nature means that several pieces have to shift around to release the first piece. This puzzle is a lot of fun and a great addition to anyone's collection, beginner or advanced. Boron is delivered disassembled.Precision wood puzzles can be damaged by environmental changes. Please r...

The "BonBon" packing puzzle by Frederic Boucher is just a ton of fun. The set of five tetrominos must be fully inserted in the rectangular box, and there is only one very specific way to do it. The solution requires well over a dozen correct moves, including rotations.The box itself is very unusual, with cutouts in the top and sides. The acrylic top is held in place with a tricky set of shoulders resulting in a great fit which retains a solid exterior presentation.BonBon is constructed with a bu...

Uri Three Bars is an unusual and beautiful interlocking puzzle. This will be our second batch after an earlier, very limited release in 2015. Dario has since improved the puzzle; the previous design was solvable in 10 moves while the new release has a level 14.2 solution.These puzzles are extras and oddballs that have accumulated in the shop.  Sometimes when we make a run of puzzles we will have a few with different woods, etc. which are too much trouble to list individually on the website.  T...
