The Sudoku story began in 1783 when Leonhard Euler, a Swiss mathematician, devised 'Latin Squares', which he described as 'a new kind of magic squares'. Euler had come up with a grid in which every number or sym bol appears once in each row or column. More than two centuries later, the difference for Sudoku players is that the grid is subdivided into blocks of nine.
