The Sudokube is exactly what it sounds, and looks like. This little mind-puzzle combines a favorite puzzle game with an age-old mind boggler, the rubik's cube. The lack of colored tiles makes it very color-blind friendly! $10.

On a related note; you know what really grinds my gears? The fact that I still have a rubik's cube sitting on my desk unfinished, but a 3-year-old can do it in 114 seconds. Am I doing something wrong, or is this just a superchild? Stupid kid and its stupid super smartness. –Travis Hudson
