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.

A prizewinner from the 2001 1st Annual World Puzzle Design competition, this puzzle was designed by the young Dutch phenomenon, Oskar, consider to be one of the world's brightest creators. 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. The key word is 'teeth'.

Great puzzle! The design is really unique, a six-sided cube combined with a five-cornered star. Many details were easy to find out, such as the routes the star were able to move (and G, you definitely haven't took a good look at the puzzle), and how the gear can be take out. The process involves some mathematics, like Todd said. Finally after some thinking and chart-making, I obtained the solution, and it moves smoothly to the finish. 5 stars is the rate.

A fun little puzzle. I'm not at all sure my solution is the best one, but it definitely works and even incorporates a little mathematics, which is nice. My only reservation is that, as others mentioned, the action isn't always perfectly smooth and it can be hard to tell whether a given move is meant to be possible or not. Still, a solid Level 3 puzzle.

One of my favorite puzzles. Looks fantastic, feels nice and heavy, operates smoothly. The start and end are both very clear, and though it's a maze-type, it can be easily learned to solve. The intriguing mechanism is credited to Oskar. My only complaint is that one side of the cube is just glued on and can get loose (and even fall off) after a certain number of plays (close to infinity though :) ). Would also make a great desk ornament or paperweight.

Definitely unusual thing, and it looks kind of interesting. Took me about 40 min to solve, and the clue is there on the cube, if you look hard enough. Nice.

Great puzzle! It is an interesting route-finding puzzle with a twist, so if you like that type of puzzle it is enjoyable. Similar to Duet. I agree with G that it is a bit confusing which moves are supposed to work and which aren't, since the legit moves are a bit sticky and the illegitimate moves seem really close to possible. That's pretty much the only thing that would keep it being 5 stars. Definitely worth getting.

I loved this one . it started an obsession for me(I now own 6 puzzles) The cast o'gear has shamfurs on sides so you can go there but you cannot pass the places with no shamfur. I loved it-but the part about figuring out the "weak spot" was easy. you just had to toy with it once you figured that out...

I thought the way it moved was pretty nifty and lots of fun. The puzzle itself isnt too hard, a nice medium. My complaint about this puzzle is that it requires some fiddling to get it to make a move sometimes and other times it refuses to move at all, which is either a flaw in the design or my inability to see some kind of mechanism that prevents me to make certain moves. The "stuck" moves really irritate me, it should be able to flow over the whole cube. If you follow the solution it will be fine but if you stray outside the given formula you'll run into moves you cant make for some reason.
