    Now, on to the Puzzles....



    Aha Box 

    DESIGNER: Allan Boardman
    MATERIAL: Bocote, Iroko
    RELEASE DATE: 10.18.2021
    EDITION: 90 Copies Released
    SIZE: 2.75" x 1.7" x 1.2"
    Small Box Two - "Aha Box" This design was Alan Boardman's IPP exchange puzzle in 2004. Alan describes it as "Designed to lure your non-puzzler friends into "our" world." Seemingly solid and impenetrable, Aha Box gives very few clues upon handling. A solution does exist, and it's quite tricky to discover. Sturdy, pocket-sized, and with a surprising amount of useful space inside, Aha Box is a great puzzle to share with friends and non-puzzlers.

    The construction of the Aha Box puzzle is exact, with a solid fit and feel. We made this run with beautifully contrasting Iroko paired with a striking plank of Bocote.

    Each copy is signed and dated; 90 copies were made for this release. Aha box ships assembled and is priced at $69.




    Soma Burr

    DESIGNER: Rod Bogart
    MATERIAL: Curly Maple, Chechen
    RELEASE DATE: 10.18.2021
    EDITION: 56 Copies Released
    SIZE: 3.59" x 2.51" x 1.48"

    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 tight or loose, ensuring a lovely solving experience.

    56 copies are available for this release, each signed and dated. This puzzle is shipped disassembled and is priced at $149.




    DESIGNER: Émil Áskerli
    MATERIAL: Walnut, Yellowheart
    RELEASE DATE: 10.18.2021
    EDITION: 62 Copies Released
    SIZE: 3" x 2.25" x 2.25"

    "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 looks, solves, and feels like the heirloom pieces it is.

    62 copies are available for this release, each signed and dated. Exhaust ships in the assembled configuration and is priced at $75.



    Japanese Wood Joint Burr

    DESIGNER: Frans De Vreugd
    MATERIAL: Ash and Shedua
    RELEASE DATE: 10.18.2021
    EDITION: 40 Copies Released
    SIZE: 3.4" x 3.4" x 3.4"

    Frans designed the Japanese Wood Joint Burr in 1999 for the London IPP. Originally crafted in very small quantities by Wayne Daniel, Frans considers it one of his nicest designs. As he still receives requests for the puzzle we decided to make a small batch. I'm glad that we did! This burr is uniquely tricky in both concept and operation.

    Japanese Wood Joint Burr is precisely crafted from Ash and Shedua. The fit and function are exact. This puzzle turned out very well and is representative of our highest standards for interlocking puzzles.

    40 copies are available for this release, each signed and dated, and delivered disassembled (unsolved). It is priced at $109.




    Large Reversible Maze (October 2021)

    DESIGNER: Masumi Ohno
    MATERIAL: Walnut and Birch Plywood
    RELEASE DATE: 10.18.2021
    EDITION: 96 Copies Released
    SIZE: 4.375" x 4.375" x 1.5"

    The Large Reversible Maze by Ohno is an interesting three-dimensional maze puzzle. The goal is to maneuver the shuttle piece from outside the puzzle to its final resting place in the middle square. Doing so is far trickier than you might imagine...typical of Ohno's designs, there are many twists, turns, and surprising moves.

    This is our second production run of this puzzle. Creation requires a combination of both laser cutting and traditional woodwork techniques. The end result is a beautifully finished puzzle with a high degree of precision which is in keeping with our signature standards of quality.

    96 copies are available for sale, each signed and dated. This puzzle is shipped disassembled and is priced at $49.






    DDD Burr Set (Stainless Steel)

    DESIGNER: Darryl Adams / Bryan Turner / Eric Fuller
    MATERIAL: Stainless Steel
    RELEASE DATE: 10.18.2021
    EDITION: 24 Copies Released
    SIZE: 1.875" x 1.425" x 1.425"

    The DDD Interlocking Burr Set is a collaborative effort between Darryl Adams and Bryan Turner. This version omits the cubicdissection crafted box, allowing us to offer it at a significant discount for customers who prioritize puzzle value over presentation. This is a limited offer and will not be further available once sold out.

    Darryl's inspiration came from Bill Cutler's complete summary of notchable pieces that can be used to form a burr shape. Bill's set of 42 pieces are sufficient to make all 314 solid notchable burrs and thousands of non-solid assemblies.

    Darryl sought a smaller set that allows enough interesting combinations to guide the solver through increasingly difficult puzzles. He called it “DDD” for “Darryl’s Dense Dozen”. The set is “dense” in that it allows for 530 possible puzzle combinations; of those, 42 have a unique solution, and 24 are solid with no internal voids.

    Bright stainless steel pieces are precision machined by Bryan Turner; assembled puzzles feel as though machine from a solid piece. This set is priced at $125.



    Aluminum Titan

    DESIGNER: Felix Ure
    MATERIAL: Solid Aluminum
    SIZE: 2" (50 mm)
    This is the aluminum version of Felix Ure's excellent Titan puzzle. Functionality is the exact same as the brass version.
    Titan is a simple-looking, yet highly challenging take-apart puzzle. The first design by Felix Ure, it's widely regarded as being both incredibly difficult and very satisfying to solve. The goal is to open the sphere but to do so you must defeat the mechanism which keeps the two spheres together.
    Machined from solid aluminum, Titan measures 2 inches (50mm) in diameter and weighs 515g or approximately one lb.
    Puzzle Mad wrote an excellent blog post; Mr. Puzzle's video review is excellent but does contain spoilers.
    Aluminum Titan is priced at $129.




    Brass Monkey Four

    DESIGNER: Steve Nichols, Ali Morris
    MATERIAL: Brass, Stainless Steel
    SIZE: 2.75" (7 cm)
    Nearly identical in appearance to Brass Monkey One, Two, and Three, Brass Monkey Four has yet again upped the difficulty. Steve and Ali's continued innovation has created a monster puzzle that is perfect for fooling those who think they have seen it before. Brass Monkey 4 looks like a standard interlocking Burr. It isn't!
    The subtle differences on the end of its pieces compared to its predecessors belie the additional complexity hiding within. Like the first few puzzles, it weighs almost 800g (1.1 lbs). Each piece is 70mm long and has a diameter of 19mm.
    Complete the collection with Brass Monkey OneBrass Monkey Two, and Brass Monkey Three. Brass Monkey Four is priced at $125.
