N2 - The mathematical brain-twister SUDOKU (Number Place in the U.S.) has
recently gained great popularity. We point out a relationship between SUDOKU and
4-dimensional Latin cubes. Namely, we assign the cells 4-tuples of numbers – coordinates
in 4-dimensional space and then consider the game plan as a 4-dimensional cube.
We also mention some variants of SUDOKU.
