How do you modify the possible numbers, e.g. whittle down the possibles? For example if you see the same pair of numbers in two cells in a row, then those numbers cannot be in any other cell in that row. How do you mark them as unavailable in those other cells?

I ve got one that I put into Word using Word VBA just for a bit of challenge. I also had an Access Sudo Solver which ran using only queries but it fails on the most fiendish ones where simple logic is no longer sufficient.

Dick,

I’ve just sent you a revised copy of DKsudoku using normal formulas iso your UDF. Much faster

I’ve added 81 named formulas to keep track of the available numbers per cell using FREQUENCY function.
=Frequency((Row1,Col1,Grid1),Bins)

The formulas used for the CF now look like:
=IF(ISBLANK(CELL01),N(INDEX(FREQ01,G3)>0);1)

Zeljiko

On opening your Sudoku.xls, my other open Excel workbooks, and Excel herself, are invisible and unavaliable. Only the userform is visible. When the userform is closed, excel is gone and my work is lost.

Don't ever ever ever write something like that again.

Beste wishes Harald

It works like a charm!
Not that I doubted about it.
