Eureka! 3D Puzzles

Those who pay close attention will see it!

Almost all puzzle companies that sell 3D wooden puzzles have the same designs in their range. Small or large, light wood or dark. Sometimes with a pop of colour. But so often the same puzzles.

A well-known Chinese manufacturer confessed to us they have no idea where they come from, but produced millions of them. With my approximately 40 years in the puzzle industry, I think I do know the origin of some designs. Some go back as far as 1,000 years!

We are reintroducing them to the market in a historically common size. Roughly 8cm. Not made from the cheapest wood but from special woods such as Red Padouk, Black Walnut and White Maple. And on the packaging, I provide some specifics about their origin. That way, the knowledge is not lost.

Puzzles with a story:

Very Important Puzzles in 3D Puzzle history. Made from beautiful woods.

anno 1897

Woodchuck puzzle

The chuck puzzle system was invented and patented by Edward Nelson in 1897. Improved by Ron Cook of the UK company Paradox Eng. Ltd. AKA Pentangle Puzzles, during the 1980s and 90s. They produced a series of chucks in which a given number of simple bridge-like pieces and one or more key pieces with an extra notch, could be built into a variety of self-sustaining threedimensional shapes. For creating bigger chuck puzzles, at that time named Papachuck (54 parts), Grandpapachuck (96 parts) and Great-Grandpapachuck (150 parts) by Cook, one would need to add longer pieces. This idea can also be used to create asymmetric shapes, assembled exactly according to the same principle as this Woodchuck puzzle. This feature is unique to chuck puzzles.

earlier than 1890

Altekruse block puzzle

Patented on June 17, 1890 by William Altekruse (USA). This burr puzzle is named after the patentee. Although, in all likelihood, the puzzle is of earlier origin. William immigrated to America in 1844 and most likely brought the idea with him from his homeland. The name “Altekruse” is of Austro-German origin and means “old cross” in German. Apparently, when he drew up the patent, William was only aware of the simplest one-axis solution. But in fact there are three solutions, depending on whether the assembly occurs along one, two or all three axes. This in itself supports our idea that he was not the original inventor.

A classic Altekruse puzzle consists of 12 identical parts. This can only be dismantled by sliding a complete section to one side before any pieces can be removed. Puzzle designer Stewart Coffin discovered 14, 36 and 38 piece variations. This type of puzzles is unusual because all parts are identical.

20 th century

Urania puzzle

This burr puzzle is a perfect example to illustrate the impact of a ‘key’ puzzle part. With the key part well positioned, another part can be removed. When then taking out the key part from the whole, the remaining puzzle parts may collapse into bits & pieces.

To this day, even the world’s greatest puzzle collectors do not know who designed this typical burr puzzle. We do know that Mr. Robert Dalloz, an established wooden puzzle manufacturer in the 1980’s and 90’s, based in France’s Jura region, added this puzzle design to his production programme sometime in the 90’s. Primarily promoted under the brand names Arjue (Uranie) and Janod Casse-têtes (CT06), this puzzle became popular and well-known around the world. But we do believe this puzzle has more history than this.

>1000 years old

Lock-block burr

Not a traditional burr puzzle, however still a burr. A burr puzzle is an interlocking puzzle consisting of notched sticks, combined to make one 3D, usually symmetrical unit. Quality burr puzzles are precision-made for easy sliding and accurate fitting of the parts. In recent years the definition of “burr” is expanding, as puzzle designers use this name for puzzles not necessarily of stick-based pieces. This lock-block puzzle is a perfect example.

The term is attributed to the finished shape of many of these puzzles, resembling a seed burr. The term “burr puzzle” is officially mentioned for the first time in a 1928 book by Edwin Wyatt, but the text implies that it was commonly used before. Records of such puzzles can be found in German catalogues from the late 18th century and early 19th century. Also, an engraved image in an encyclopaedia from 1698. But there are claims of the burr being a Chinese invention, like other classic puzzles such as the Tangram. The puzzle known as “The Chinese Cross” is in fact the most well-known and presumably the oldest of burr puzzles. That makes the burr puzzle over 1000 years old.

3 worlds come together

Nexus puzzle

Whereas wooden puzzles are usually constructed symmetrically, here you can notice an optical difference, which not only makes this puzzle look more special. It’s the combination of bridge-like chuck parts with classic burr parts with a notch, that result in an apparently asymmetrically sectioned Chinese Cross puzzle. But where the historical Chinese Cross puzzle locks itself with 1 solid key piece, an unnotched stick that slides easily out, there’s more going on here.

+ The Chinese Cross Puzzle is said to date back more than 1,000 years.

+ In the UK, as early as 1698, there has been signs of what we now call ‘burr’ puzzle parts.

+ In the US, chuck puzzle pieces are officially known to us since 1897.

Or how puzzle systems from other times and worlds can merge into one beautiful whole!

18th century

Japanese dice puzzle

Little is known about the early history of this puzzle design but puzzles very similar to this were certainly already produced in both Asian and European countries as early as the 18th century. In the 1803 catalogue of Fa. Bestelmeier, a German toy manufacturer, there were 2 images of such puzzles.

Puzzles of this type were mainly made in Germany, but by the late 1930s the market had been largely captured by Japanese manufacturers. Yamanaka Kumiki Works Co. being one of them. Since then, this particular puzzle system can be found in several geometrically shaped puzzles, such as a sphere, a cube, a barrel, etc.... Japanese puzzles of this kind are called, you’ll never guess, “Kumiki” and are believed to be related to the traditional construction of wooden buildings where no nails or glue were used.

Anno 1965 and 1968

Hectix Puzzle

This puzzle idea was discovered first by Bill Cutler around 1965 and independently by Stewart T. Coffin in 1968. Stewart is known as “the world’s foremost creator of interlocking puzzles”! With only a slight variation in the notches, this puzzle is based on Stewart’s original Hectix design. Designed and cast in epoxy in late 1968. Patented in 1973 (US-patent no. 3721448). Made from 12 hexagonal sticks with notches. This puzzle marked the beginning of his puzzle company. In 1970, a license was granted to the company 3M for production in injection-molded styrene. In 1976, the license was transferred to Avalon Hill until 1979. Approximately 100.000 pieces were sold, which was a huge success at the time. The current location of the mold is unknown, which any enthusiast puzzle collector would cherish to find. Stewart, born in 1930 and still alive at the time of this release, has personally given us permission to reproduce his puzzles.

The Nest-Pin Puzzle

A combination of Stewart T. Coffin’s ‘Nest’ designs and his ‘Pin-Hole’ puzzle. Both created in 1976. Our design is a light version of his Cuckoo’s Nest and Locked Nest. We drilled holes at a 90° angle, while Stewart used a 70° angle. When assembling or disassembling this Nest-Pin puzzle, the relationship with his Pin-Hole design becomes clear. Stewart T. Coffin, born in 1930, is an American puzzle maker. He is considered by many to be one of the best designers of polyhedral interlocking puzzles in the world. Puzzles designed by Stewart may be freely reproduced, provided you contact him in advance and send him a few copies. Stewart, still alive at the time of this release, has personally given us permission to reproduce his puzzles.

SIXI Cube puzzle

Created by Vaclav Obsivac (nickname Vinco) from the Kingdom of Wallachia in the Czech Republic. Vinco was born in 1962 and had a natural interest in symmetrical geometric shapes made from beautiful types of wood. His interest in puzzle making began in 1999, thanks to a world puzzle championship in Brno, Czech Republic. Inspired by the work of Stewart T. Coffin, Tom Lensch, Philippe Dubois, Pelikan Puzzles and others, Vinco designs and produces various types of puzzles, including packing puzzles and interlocking puzzles. However, most of his puzzles work on the basis of coordinated movements. This SIXI Cube puzzle is one of his simpler interlocking creations, allowing you to become acquainted with his designs. But beware, we included some science as a challenge.

Anno 2005 to 2022

Akaho Puzzle

From the Kingdom of Wallachia in the Czech Republic, we bring you this pin & hole packing problem, devised by puzzle designer Vaclav Obsivac (nickname Vinco). The Akaho puzzle is part of Vinco’s ‘HoWeDia’ project. This project is a perfect example of how new puzzle designs and names come about, or how puzzle brains think. In this case, it concerns the transformation of Vinco’s puzzle design ‘Eight Houses’, created in 2005, into this ‘Akaho’ puzzle, created in 2022. Have we made your eyes light up? Take a look at the download section on his website vinco.cz.

Extra bonus: Think -outside the boxand look for more pin & hole fitting shapes. And a creative mind turns an XXL version into a puzzle coffee table and side tables.
