Description
Hanayama Difficulty Level 3 – Normal
The object of this puzzle is to remove the gear from the cube.
The O’Gear puzzle is a three-dimensional maze and you must skillfully weave the gear part through the cube to remove it. It’s always hard to say how many moves there are to complete a puzzle like this. It will definitely be more than 15 but depending on how many wrong paths you take through the puzzle it could end up taking many, many more.
Originally called the Sunflower, this puzzle was designed in 2001 by a famous Dutch puzzle designer Oskar van Deventer. The puzzle received an Honourable Mention at the very first IPP Puzzle Design Competition held in Los Angeles. Oskar has since designed many puzzles for Hanayama and others and won many awards. Oskar is considered to be one of the brightest puzzle creators in the world.
True to form Oskar has given some clues while at the same time not making the exit path that clear cut. There’s a small triangle on one face that you can use to help orientate the gear when moving around the cube. The cube is designed with a number of raised edges that allow the gear to rotate but Oskar has also added some sharp edges that stop the gear rotating in certain positions. Just when you think you’re nearly out you’ll likely find the path is blocked by another sharp edge!
The key word is: Teeth
Size: The width of the gear part is 70mm. The cube is 35mm x 35mm x 35mm. Presented in a view window box which is 75mm x 115mm x 45mm
Hanayama puzzles come packaged with a printed solution (not offered as standard by other sellers) but try the puzzle without it first. If you manage to do it you’ll really get that fantastic feeling of Aha!
