12 Sided IQ Pentagon
You’ve heard of a 12-sided die, but what about a 12-sided Rubiks Cube? Well, I guess it’s not technically a cube anymore, but that’s what the 12-Sided IQ Pentagon is. Unfortunately it’s currently out of stock, but keep an eye out for when Brain Death — as the makers refer to it — is available again. Or, you could settle for the slightly-less mind-blowing Megaminx Duodecahedron Puzzle, which is still likely to keep you frustrated for days/months/years.
