It's a little late to make a Christmas or Hanukkah gift, but the IQ Cube might be a suitable New Year's present for the puzzle-obsessed people in your life. You know, the ones that are always telling you that their Rubik's Cube is just way too easy?
By eschewing the traditional 3x3x3 layout of cubes that comprise the iconic 1980s era toy, this unofficial successor features either 3x3x7 or 3x3x9 pieces, depending on how much of a challenge you want. While apparently the same physical size as a standard Rubik's Cube, these puzzles feature more rows of blocks that are very thin, thus creating many times the number of possible solutions.
The two "super cubes" are a bit pricey at $27 each, but there could always be some endorsement money for becoming the world record holder in solving one of these devious devices. Just do expect to be as fast as Feliks Zemdegs, the current Rubik's Cube world record holder — he can solve the traditional 3x3x3 puzzle in just 5.66 seconds.
