I have just created a tool to help solve the Sudoku puzzles: the forret.com Sudoku Helper. I’ve added it to my Forret tools directory.

You solve a Sudoku puzzle by filling in numbers (1-9) in a 9×9 square.

Rule 1: everyrowshould contain ALL 9 numbers, and no number can occur more than once.Rule 2: everycolumnshould contain ALL 9 numbers, and no number can occur more than once.Rule 3: every3×3 squareshould contain ALL 9 numbers, and no number can occur more than once.(see also sudoku.com)

De Morgen (Belgian quality newspaper) has just started printing such puzzles in every issue, and they are an addictive hobby. Here they are: the EASY, MEDIUM and ADVANCED one for Monday June 6, 2005.

My Helper just checks the 3 rules above and will indicate which cells can easily be filled in because there is only 1 option left. Yes, it can be kind of a spoiler, so only use it to get out of a deadlock, or if you’re in a hurry, or to show off.

The more difficult puzzles will require you to cunningly plot your strategy 2 or 3 steps ahead, which my Helper page will not do or help you with. If you want to spoil even these brain gymnastics, check Sudoku Solver by Logic

For those of you who like a client program that can work off-line, check Sudoku Solver (Windows – free).

Hi mates,

Here is another, excellent online free sudoku web site…

And another one, here:

http://www.sudoku-san.com

It has four graded puzzles every day, an online workpad and ‘intelligent’ assistance – if you ask for help, it gives proper explanations about what you can do next. You can also print the puzzle out, if you prefer just to scribble.

It’s a fairly new site so all feedback appreciated,

thanks,

Alastair

Another solver, this

time as a Java applet, nicely

shows an animation of the solving

process.

sudoku.klaas.nl

Built-in puzzles, speed

control slider, menubar, tooltips

and look & feel options make this a good

demonstration that Java applets

can have a familiar and friendly

interface. See

Essential Guide and Links to Sudoku

If you like sudoku I recommend you PrintSudoku.com. I has 6 new sudokus every day ready for printing.
