The science behind Sudoku
Article Abstract:
The game of solving a Sudoku puzzle, which poses a number of intriguing mathematical problems with a host of challenging issues, is reviewed. A standard Sudoku is like an order-9 Latin square, differing only in its added requirement that each subgrid contain the numbers 1 through 9, but puzzle mavens have come up with an array of approaches to attacking Sudokus with entertaining variations on the game.
