By registering Sudoku.xls for £4.99 you can can click on the  SU DO KU button and  buttons to get help on completing the grid.

The  button gives the absolute minimal help, adding just 1 number to the grid.

 

TheSU DO KU button buttons allows you to set the “Number of Iterations  from 1 to 20 to offer either some, or a lot, of help.

Setting “Number of Iterations  to £€ (Pound sign Euro sign) just solves the puzzle – really cheating!

You can also set the number to **  (2 asterisks) and it will invoke the “Super Solver” function, but giving you the option to proceed or not.

 

This function will find the solution to almost all valid Sudoku Grids with a unique solution (I haven’t found one it doesn’t work for, yet. However, if anyone does, I’d be pleased to hear from them with details). Due to the way it operates, it will also find one solution for many non-unique grids. It won’t (of course) find any solution for invalid grids.
