The goal of a Su Doku problem is to complete the published grid so that no number appears more than once in any row, column or 3x3 subgrid. The rules are described more fully on the official Su Doku website, to which a link is provided above. To set up the solver, simply type the numbers printed in your puzzle into the corresponding squares in the small grid above. Squares that are blank in the puzzle should be left blank in the grid. Once all the values have been copied across from the puzzle, use the button beneath the grid to generate the hint sheet on the left.
