Thanks Chandoo..I missed this post of yours.
1) Just as I did this, I was pretty much interested in creating an excel that could generate SUDOKU puzzles.
2) I haven’t tried more than 10 iterations..but yes, more difficult problems would get solved if you increase the iterations in the code.

@cdascgil: Thank you. I have noticed it too. But the macro stops after 10 iterations. May be you can increase the number and see if it solves the tougher ones.

@Struzak: Thank you. and thanks for the link to sudoku generator.

@Modeste: Wow, that is cool.

@David: try now, I have uploaded the Excel 2007 version originally. Now I have replaced the file with an Excel 2003 compatible version.

It seems that others have successfully opened this file, so what am I doing wrong? I can’t see a workbook in the zip file so can’t even look at it! (It probably doesn’t matter, because I only have Excel 2003.)

The content of the file I downloaded didn’t seem to have anything to do with Sudoko. (It has folders _rels; docProps; & xl).

Dear Arnold,
Assuming knowing the rules to form a given Sudoku and fully completed,
there are a multitude of grids with the same relations
that is to say:
- Permutations digit numbers
- Rotations per group of columns or rows
- But also rotations in groups

applying these principles to a bank of model grid
it is possible to generate and print indefinitely differents grids for pleasure always renewed …

That’s what I have done :
http://www.cijoint.fr/cjlink.php?file=cj200910/cij9dWRCr1.xls

- I don’t create any of the original model grids, nor the soluce proc
- the worksheet is protected with blank

Print and Enjoy !!!

@PHD: Another masterpiece.

@Arnold: You can try the Sudoku Generator at http://www.opensky.ca/~jdhildeb/software/sudokugen/. This one does not use Excel, but can be usefull as well.

Only works for simple puzzles.
Nice macro, though

Hi PHD

Is there an excel sudoku creator, my mother in law can’t stop doing them and buying books is expensive?
