I’ve never been able to solve a Rubik’s Cube. Granted, it’s been a good number of years since I actually attempted. Even still, that puzzle seems like such a daunting challenge. So sometimes it blows my mind when I see that people have found ways to actually make the Rubik’s Cube even harder.
If you really love a challenge, you can go for the Sudoku Cube, which combines the challenges of both the Rubik’s Cube and Sudoku. It only costs about $6, and is sure to give you hours of frustration while turning whole columns of numbers. If you’re good at both of these games, then this should prove rather entertaining.
I'm afraid I might have to buy one of these for my SUDOKU addicted sister but when I entered "SUDOKU CUBE" on amazon.co.uk it turned up a whole selection starting at only £1.54 !
