The Giant 12-Surface IQ Pentagon and Petaminx Puzzles
Posted on September 20, 2009
Those who find the Rubik's Cube not challenging enough may be interested in this dodecahedron puzzle. This looks like it would take a very long time to solve. The 12 Surfaces IQ Pentagon costs $49.90. It was available from Brando but can no longer be found there.
This video shows the even more complex Petaminx puzzle, which is a dodecahedral puzzle with nearly 1,000 moving parts. You can find out more about the Petaminx at PuzzleForge.
There is also the Rubik's 360 spherical puzzle from Rubik's if you like challenges.
