The design has one 2x2 hole, half-folded over a cage edge, and another half hole at a side (Oskar’s intellectual contribution). The puzzle requires many rotations. This...

"This was our exchange puzzle for IPP41, inspired by Perry McDaniel's presentation showcasing the venue. The goal is to castrate the bull and remove its balls. It's primarily a sequential movement puzzle, where the internal maze pieces need to be manipulated to get the balls out. This sequence is a bit easier than Triorchidism, requiring about 10-12 moves for the first ball. However, there are a couple of hidden steps and tools, so it could be called an SD-lite as well. Made of 3D printed piec...

Kevin Sadler wrote about it:“This very attractive diminutive 9 piece burr designed by Alfons Eyckmans is gorgeously made from Padauk, Wenge and Ash. It is a wonderful challenge, perfect for puzzlers who want to be certain of burr success. Alfons has enormous design skills and has created incredibly complex high level burrs that are almost impossible for anyone other than the burr expert (that does not include me) but also designs puzzles that have more moderate disassembly levels, amenable to ...

This puzzle requires some very tricky 22 moves to remove the first piece from the assembled shape. Although a few pieces tend to rotate during the solving process, there seems to be no shortcut solution using rotational movements. It can be solved using rotational movements, but it still requires about the same steps as a rectilinear movement solution, though it is tricky to count while it involves rotational movements. The number of possible assemblies of the puzzle is a very large 30,592, a...

This is the fifth version of the Grooved 6 Board Burr series, and its configuration is very similar to the first version. Also, the number of moves needed to disassemble the first piece is the same as #1, 22 but #5 has a tricky feature.
