Sudoku is a puzzle with a grid containing nine large blocks. Each block is divided into its own matrix of nine cells. The rules for solving Sudoku puzzles are very simple: each row, column and block must contain one of the numbers from '1' to '9'. No number may appear more than once in any row, column, or block. When you've filled the entire grid, the puzzle is solved.
'Su' in Japanese means numbers while 'Doku' means single. Sudoku means single numbers. Therefore, in the sudoku game, we have to fill in numbers without repetition. The Times in London helped.
