We’re putting “Rubik’s Cube” in quotation marks because we find it funny that due to trademark issues, this particular puzzle is actually called the IQ Brick. Yes, the name Rubik’s Cube has somewhat become genericized and has come to refer to any similar puzzle, so yeah, we guess this is the (wink wink) IQ Brick, a 13X13X13 puzzle that should take the average human a few years to solve. The number of possible combinations is so large, we can’t calculate it, let alone display it in any meaningful way. It’s just mind boggling. But one thing’s for sure, if solving puzzles calms you down, you’ll be as smooth as a sloth for the rest of your life. That’s after you pay the $320 asking price, that is.
