On the Subject of Regular Sudoku

This is as basic as you can get with a puzzle

The module generates a sudoku puzzle.

To solve the module, fill the blank numbers so that each row, column, and 3 by 3 subgrid contains the number 1–9. There is only one unique solution on the given Sudoku board.

Clicking on a blank tile will change the tile to a “1”. Clicking on a tile that is not “9” will add 1 to the number shown. Clicking on a tile that is a “9” will turn the tile blank.

When the module is solved, all gray colored numbers will turn green.
