Oskar is the master of creating new n-ary puzzles, and Derek Bosch is the master of the helical burr.  Each is responsible for designing Zach Zieper's exchange puzzles from the past two IPPs — IPP41 (Houston 2024) and IPP42 (Tokyo 2025) — each inspired by Zach's dog, Louie.  "Screwy-Louie" from IPP41 is an n-ary puzzle which can reassembled with 2, 4, and 6 pieces, and "Twist My Wiener" from IPP42 is a 4-piece helical burr. Both puzzles come as received in their original packaging, complet...

One of two things can happen when the minds of Wil Strijbos and Peter Hajek come together:  EITHER total annihilation of the world, or the creation of a FIENDISH and DIABOLICAL puzzle.  Fortunately for all of us, the latter was the result when these two puzzle genius heads came together to create Peter's exchange puzzle for IPP41, held in Houston in 2024.  The goal of Burrglar is simply stated:  put the (only!) three pieces toge...

Tornado Burr was designed by Juno in 2007 and originally produced in a small batch by Mr. Puzzle (Brian Young) in 2008, and reproduced in a small batch by the late Eric Fuller in 2010.  Finally, this past year (2025), Juno's company (Pluredro) manufactured Tornado Burr.   Its three beautifully contrasting woods are Bubinga, PNG Rosewood, and Koto.  Tornado Burr is sold out on the Pluredo web site.  When it was availa...

This is a duel-layered 40 piece wooden jigsaw. Vintage but age unknown. I really mystery but amazing little piece that hits the perfect spot for tricky but doable.

The Hyperboloid Burr is a very fun six-piece burr puzzle made from identical hyperboloid pieces, designed by Oskar van Deventer and Naoaki Takashima.The puzzle has two solutions. The six-piece version is a put-together that assembles and displays well, but if picked up by a single piece falls apart under its own weight. The seven-piece solution is completed with a satisfying "click" and holds together well.Both assemblies are made possible by machining to very accurate tolerances. A mere 0.03mm ...

We are excited to work with another new designer Tyler Hudson for this release. Parasitic Burr is an eight-piece burr in the disguise of a traditional six-piece burr shape, done in an ingeniously simple way. Six standard burr pieces interlock around two identical tetracube pieces which are hidden inside the belly of the final assembly. The unique solution is an approachable level 3, and figuring out the correct placement of the smaller inside pieces makes it a very fun assembly puzzle. Look out ...

Slideways by Ray Stanton and Akio Yamamoto is one of our favorite Interlocking Burrs. Three simple, identical pieces combine to form the symmetrical shape. The solution is trickier than it seems, and some struggle even after even seeing it performed in front of them. There is a tricky concept in play that must be understood; once discovered, the pieces' smooth movement is addicting. Slideways is not the most challenging puzzle, but it just may become your favorite.*******************************...
