Children are going crazy for it. Sudoku is a number-placement puzzle based on logic. Teachers have begun recommending these games as mind sharpeners for all ages. It is not only fun; it's stimulative and cool! HOW TO PLAY The grid is divided in 9 squares (called regions), each of them divided again in 3 x 3 squares; you are starting with various digits given in some cells (the "givens"). The aim is to complete the grid by filling the empty squares with 1 digit per square (1 to 9) so that each digit appears only once in a row, in a column or in a region.
