some things that help me solve these puzzles

1. each row must total 45
2. each column must total 45
3. each 3 x 3 must total 45
4. I created an spreadsheet to automatically track my entries and each total, so I don't have to remember what remaining numbers I have to deal with in either a column or a row and how far away from total I am in any given row / col / 3 x3

The rest is blood, sweat and tears...

We have had a recent discussion about ways to fool a sum to 45.

have a look at www.brightonandhove/sudoku/solver5c.xls...

Its an Excel file and macro with full access to the macro - to see exactly how the solver works - and it's also a workgrid so you can stop it solving and just do it yourself....and it gives you all the possibilities.
