Cast H&H
Just as the name suggests, this puzzle, shaped like the letter "H", is made
of two pieces entwined together. At a glance, the pieces that make up the
puzzle may appear to be of the exact same shape, but the pieces actually
differ slightly. Do you think you can disassemble the two pieces? The
movement of the pieces is very tricky, so you need to be careful that your
memory doesn't play tricks on you too.
The theme is "Entwine" ................ Solution by Markus Götz

O'Gear
A prize winner from the 2001 1st
Annual World
Puzzle Design Competition, The gear exhibits a unique kind of movement. Once together in its final form of beauty, the gear fixed in place in the cubic box could very well serve as a desk decoration to satisfy a kind of soothing, intellectual curiosity. |

|
Cuby
This cube, is a maze through which a loop is interwoven. The position of the piece trapped inside can be changed by it being moved in a unique way. However, the dilemma is how to remove that piece. When first invented, the start point at which the piece could be removed was not fixed. |

L'oeuf
This labyrinth-style puzzle, done up in the shape of an egg, gained prize-winning honors at the 2nd Annual Puzzle Design Competition in Antwerp. "The Egg", which is of course the key word here. Simply put, the goal is to separate the two pieces and then put them back together.

Equa
We have created a puzzle that takes on a spherical shape of an astronomical model composed of a planet and its surrounding ring.
The planet positioned tightly inside the ring looks as if it cannot be taken out, and all you can do with it is rotate it on its axis. |
|
|
Duet
At first glance, it looks as if there is only one ring hanging from the grid but there are in fact two rings attached with a magnetic force.Can you separate them from the grid and return them to their original positions?After you conquer that, try to fit the two rings at the four-crossing points on the grid indicated by the numbers. |
|
|
Chain
There's a whole world of wisdom wrapped up in this Oskar masterpiece. The three pieces can be separated and then joined again in their original form. What's special about this puzzle is that it can be solved in three different ways, depending on which of the three pieces is chosen as the middle piece.

|
KeyRing
After completion of this puzzle by Oskar, the words "Key" and "Ring" should be properly lined up with each other. This is vital. If you try to put the pieces back together without lining the words correctly, you will have failed even after achieving what appears at first to be a successful matching. It should read "Key Ring" even when upside down. The wording design is courtest of the prodigy, Scott Kim.

Nutcase
There are two goals to the Cast Nutcase :
1. Remove the small nut by disassembling the Cast Nutcase.
2. Cast puzzle enthusiasts (nutcases) can enjoy trying to change the wording on the bolt from 'nut-case' to 'case-nut'.
The key word is "Interlocking". |

Marble
This puzzle has such a beautiful shape that it could easily be mistaken for a piece of jewelry.
Its surface features extremely unusual cuts; actually, this marble is a puzzle that can be broken up into 4 pieces.
This advanced design is the creation of Bram & Oskar. If you succeed in breaking up the marble, carefully examine the surface of the sections of each piece. The theme of this puzzle is "Sphere." |

Cast Oskar
Hanayama’s very first cast puzzle from an independent puzzle designer.
It was designed in 1987 and produced in 1988.
The production was discontinued because the transparent plastic cover did not match
with the cast-metal theme. Given its limited production quantity and historical value,
it is truly a collector’s item. The object is to slide the two keys out.

|
Dual Circle
Dual Circle was developed by Oskar in collaboration with Bram Cohen.
Bram presented an abstract mathematical concept, which he wanted to be reified into a mechanical puzzle. The object of the puzzle is to scramble it by turning the rings and then restore the colors.
|
|
 |
Easter Egg
Easter egg is a variation to a well-known puzzle theme of interlocking circle.
The object is to take the puzzle apart and put it back together again.
