If you can solve the Rubik's Cube behind your back while blindfolded, then maybe it's time to step up and play with the big boys.
The Sudoku Cube takes the Rubik's Cube to the next level, replacing colors with numbers. Like the regular Sudoku game, the idea is to get the numbers 1-9 on each side of the cube, with each line solving like the print version. Good luck.
So bust out the Red Bull, because it's gonna be a long time solving this brainteaser!
