Sudoku Madness

Sudoku Madness 500 sudoku puzzles for all ages, with 5 different difficulty levels. Sudoku is a logic-based, combinational number-placement puzzle. The objective is to fill a 9 x 9 grid with digits so that each column, each row, and each of the nine 3 x 3 subgrids that compose the grid contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution. Remember, the same single-digit may not appear twice in the same row, column, or any of the nine 3 x 3 subregions of the 9x9 playing board. LET THE FUN BEGIN
