Product Description

Note: Our level rating system is different than Hanayama's.  Hanayama's level 1 is equivalent to our level 5.... level 6 is equivalent to our level 10.

The World Puzzle Designers' Forum, held in August 2000 in Los Angeles was where I first met my close friend Oskar. This puzzle is based on a disc based puzzle that he showed me at that time. Battling it out with this puzzle is like putting your mind to the test against one of the world's sharpest minds in Oskar. The idea to keep in mind here is 'circle'.

I think this puzzle should be at least difficulty 3 (7 here). Of course it is trivial to solve it just by playing with it, but there are two different solutions depending on how you put the two pieces back together. And remembering both of them (the shortest path, not just circling around until you take the pieces apart) is quite difficult. It took me several days to manage to discern them. I also like the material they are made of very much.

Quite easy for a level 2. I had this solved within a minute of unpackaging it. I can still wander down the wrong path when solving this puzzle, so it does have some replay value. It's a nice design and fun to tinker with.

I like this puzzle because the mechanism is quite interesting, and it's fun to play with.

Great puzzle. Never mastered this one, just trial and error. Not as durable as some stepped on and now the joy is over! :-(

This puzzle was pretty easy to figure out, but I still have problems trying to find my way through it; it is like a maze.
