What do you get when you combine a colorful Rubik’s cube with the addicting fun of Sudoku? The Sudoku Cube of course. Try the easy level [one side] first to rearrange the squares so that the numbers 1 through 9 are shown, then work your way up to the mind-numbing level of doing all sides at once. This should keep you busy for awhile. It comes with a booklet and is currently on sale for $8.99. –Leah Cheng
