The Rules

Sudoku is a simple puzzle game where you're given a partially filled 9x9 grid. To complete the puzzle you must fill in the grid so that there is a single instance of the digits 1-9 on each row, column and in each 3x3 subregion.

The Solver

This solving application is written in pure DHTML. At the moment compatibility has been tested with IE6 and Firefox, if you're using another browser and are having problems please email me so that I can try to sort them out. A screenshot of any glitches would also be most welcome along with any javascript errors that the browser reports to you.

To fill in a number on the grid, simply click the grid you'd like to fill. A submenu will appear with the digits 1-9 and a blank digit available. Select the digit you'd like to place in the cell and it will be set in the puzzle.

You can also add hints to the board to keep track of limited possibilities in certain squares. To do this hover the mouse over a square and press the numerical key ('1' to '9').
