The two pieces are filled by four cubes which can manuever internally. The solution is tricky and non-intuitive...all pieces are accessable so there is no need for gravity shifting. There is a rotation shortcut which is quite apparent with disassembly but not at all apparent during assembly, which is nice in my book...almost like two different ...

The moves are so unconventional that the level 8 solution is tougher than you would expect. Disassembly has a trick to it as well. This is an excellent puzzle, I'm glad I made it, and I'm looking forward to its big brother "Schism" in the next update.Construction of this puzzle is excellent. Fit is dead...

Classic Osanori Yamamoto - 17 moves to remove the first piece!

A beautiful little puzzle from Klaas, who had this to say on the Pelikan website :-“This puzzle is gorgeous in contrasting Wenge and Padauk. With level 10.3.2.3 it should not be too difficult. While assembling / disassembling the pieces move around one another, hence the name Little Dance.”

Another Osanori Yamamoto/Pelikan killer!  Here's what Kevin Sadler had to say on the Pelikan website :-“The Aqua Toto puzzle is my 2nd favourite from the group to be released. This is also a classic Osanori Yamamoto design consisting of a 2 piece frame and 2 Wenge pieces which straddle it. Separating the pieces requires that the frames be moved and the Wenge L's be negotiated through a changing maze to a position which allows the characteristic rotation moves. The rotational moves came to me ...

Another Osanori Yamamoto challenge from Pelikan - described by Kevin Sadler :-“Rose is yet another interlocking design by the wonderfully prolific Osanori Yamamoto. I saw these when he first showed it off last year and hoped that someone would make it available. How could I resist this version by Pelikan – especially one so perfectly made? My copy is made from Purpleheart, Wenge and Acacia and the precision has to be seen to be believed! The concept is that of a board with a man shaped hole ...

Essentially a 3-piece burr (Gigaburr) with pieces augmented to form a cube.  Level 6.

A colourful assembly crafted by Brian Menold.  Sue Young described the puzzle thus :-"This puzzle is a combination of six pieces, each being a unique shape made by joining three rods together on perpendicular axes. Bill Cutler’s GENDA program reports three solutions, none of which it can disassemble. It is, however, possible to disassemble one of them with a rotational move that the computer has not yet mastered. The other two are as the computer found; impossible to get apart. This gives the...
