How to play
Billed as the next crossword, Sudoku's simplicity is its beauty. Although it is a number game, Sudoku requires no mathematical skills - just a keen grasp of logic and plenty of patience.

The rules of the game are simple: You simply fill in all the squares in the grid so that each row, column and each of the 3x3 squares contains all the digits from 1 to 9 without repeats or omissions.
