Dovetail Burr is our follow-up to the Japanese Wood Joint puzzle we released last month. Both are part of the series that Frans designed nearly 20 years ago. Inspired by traditional Japanese woodworking joinery techniques, Dovetail Burr was Frans's IPP 20 Exchange puzzle.Dovetail Burr remains an utterly unique interlocking board burr concept despite its age. The presence of matched dovetail joints forces each pair of pieces on a given axis to interact with the other. This innovation creates a di...

The Grooved Three Piece Burr by Kouki Kusumi won an honorable mention in the 2020 IPP Design Competition. This fascinating assembly has three identical pieces yet only one solution. Despite their similarity, the pieces interact uniquely to assemble into the traditional board burr shape. With a level 8.2 solution, this puzzle is approachable yet fun for all experience levels.************************************************************For multiple items, combined shipping is available. Simply mess...

Blah Box is the result of the accumulation of ideas I had while trying to design a simple mechanism for the box containing the DDD Burr Puzzle. I wanted to make a simple trick opening mechanism for DDD, but in the end, discarded the idea because it would overly increase the price of the puzzle. I came out of the design session with some solid ideas, which, when combined, turned into a rather interesting box on their own. I was feeling rather "Blah" about my failure with DDD and decided to name t...

Japanese Wood Joint Burr was designed by Frans de Vreugd for the London IPP in 1999. Originally crafted in very small quantities by Wayne Daniel, Frans considers it one of his nicest designs. This burr is uniquely difficult in both concept and operation.We previously released a small batch last year, and decided to make more after a lot of positive customer feedback. This run was precisely crafted from Ash and Wenge. The fit and function are exact. Production turned out very well and is represen...

Oskar's Matchboxes have always been one of my favorite designs. Very few puzzles come close in terms of originality, appearance, and overall appeal. The five pieces consist of an outer box and inner tray cleverly glued together. The goal is to assemble the pieces to contain every tray inside a box. With only two solutions, this is quite tricky! Matchboxes is quite time-consuming puzzle to craft. Each piece is constructed using the same robust shoulder joinery we used to make the Tube It In puzz...

William Ja has knocked the ball out of the park with his first design. The cheekily named "Triorchidism" was inspired by our earlier "Box with Two Balls." William expanded the idea by increasing the playing area to a 3x3 space and adding the third sphere to create a more complex and difficult challenge.The goal of Triorchidism is to remove all three marbles from the box. Confounding this is four wood pieces trapped inside. Moving the pieces and marbles creates an ever-changing hybrid interlockin...

Frederic Boucher designs some of the most unique puzzles around. His work often surprises and confounds even the most experienced solver. Anti-Gravity Box+ is no exception. This brilliant packing puzzle stands alone in both concept and creativity.We long-delayed production of AGB+ due to the complexity of prototyping and manufacture. The construction of this seemingly straightforward puzzle was, in fact, quite difficult, requiring many days of prototyping and calibration.The goal of AGB+ is to p...

Soma Burr is Rod Bogart's amazing creation which combines the fabled Soma Cube with a traditional three-piece board burr.  The solver must fit the cube inside the burr; with only one solution, this is a tricky proposition. A delightful combination of packing puzzle and interlocking burr, Soma Burr is sure to become a favorite!Construction of Soma Burr was done with extraordinary attention to detail. Each Soma piece is precisely milled and finished with full bevels. The fit is perfect; not too t...

"Exhaust" is a very unusual six-piece interlocking burr that combines board and burr piece shapes to achieve a fascinating symmetry. The two board and two burr pieces interact with the two hybrid-style pieces to create an unusual challenge. The solution is devious and clever.Construction of Exhaust went very well. The end-grain joints of the hybrid pieces are reinforced by a half-shoulder for strength, ensuring that this puzzle will stand the test of time without mechanical failure. Exhaust look...

The following wording has been copied from the original page on Brian Youngs web site."8 hexagonal sticks & 8 dowels. Two stick-dowel pairs joined to form two different elbows. Another two joined to form two different cross pieces. 12 pieces in total.Not sure if anyone ever answered Stewart’s challenge from 1987 to analyse all the variations using different elbows to make this shape but Brian has made at least one of the possible variation here. He not only made this puzzle with two different ...

Another rare Coffin original (see my other listings).  #114 in Stewart's numbering system and, for me, the hardest of all the Cluster Buster series as it introduces coordinate motion into the mix!

A little small than Improved Cluster Buster which I have also listed.******************************This is one of a number of rare/collectible/hard to find puzzles that I (Steve Nicholls) am selling on behalf...

Coffin describes this as a simple puzzle that looks like the class six-piece diagonal burr, when you try to take it apart by the usual way of pulling on two opposite pieces nothing happens. He describes it as a novelty or practical joke saying "For more fun it can be expanded in all directions to almost the point of collapse"This version has been made by Pelikan Puzzles.******************************This is one of a number of rare/collectible/hard to find puzzles that I (Steve Nicholls) am selli...
