Unusual packing problem by Dr. Latussek.  Pelikan's description is at  X-Ray-Cube – Pelikan Puzzles

In-Out is a 3-D assembly puzzle made of three beautifully contrasting woods (paralleling the 3-D axes).  It was designed by the prolific Israeli puzzle designer Philippe Dubois, and exchanged by the great Dan Feldman (designer of the famous Danlock puzzle lock) at IPP19 in London in 1999.  The puzzles consists of 24 pieces, 12 each of two types, which must be assembled to form the highly symmetric figure.  The puzzle is as received at IPP19 in 1999, and has never been taken apart.  It still ...

Bird 11 by Yuu Asaka. Pack the "birds" into the frame. A little about myself and the puzzles. I am a solver / collector. I try to collect various types of puzzles from various designers / makers.

I keep the humidity where the puzzles are between 40-50% with the average being approximately 48%.Buyer will pay shipping and will ...

"Boxy by László Molnár is a unique packing puzzle concept. You must pack the five simple pieces into a clever box with a rotating and connected top/bottom panel. Joined by a dowel, the top and bottom move together and therefore limit access to the interior. As the box fills with pieces, the movement of the lid is increasingly restricted. Despite multiple possible configurations, you can assemble only one in a particular order. Boxy is a fun, challenging puzzle.I'm thrilled with how this puzzl...

Kevin Sadler wrote about it:“X-ray cube is another challenge from Dr Latussek – the box has been beautifully made from Cherry and the pieces inside are Dark oak. I think it's named this way because the pieces need to be arranged in the box so that the pieces no longer obscure the holes in the top and bottom of the box allow you to see all the way through. In my website review I had not realised that this was the requirement and I had spent the best part of an hour trying to put the pieces ba...

Small Box Two (Aha Box) was Allan Boardman's IPP exchange puzzle in 2004. Allan 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 Aha Box puzzle is exact, with a s...

This is a beautiful little treat! A 3 piece burr; How hard can it be? This little puzzle is small enough to fit in your pocket and big enough to hurt your brain. This is what Brian wrote about it on his website, WoodWonders ,"I made this terrific puzzle a few times over the past 10 years but I think this one is the nicest looking version I have made. This is a "must have" for every collector. They don't often go up for sale or auction but even when they do they are tough to get. Lots of rotatio...

Tube Maze was George Miller's first 3-D printed puzzle. George writes: It was designed by Oskar van Deventer and is a very typical Oskar maze where the piece traversing the maze needs to go through a parity change (be flipped) before a solution presents itself. Another feature of all Oskar puzzles is that the goal is obvious. Here it is to simply remove the red ring.It is a beautiful worthy of being called a work of art in its own right.
