By
registering Sudoku.xls for £4.99 you can can click on the 
and 
buttons to get help on completing the grid.
The button gives the absolute minimal help, adding
just 1 number to the grid.
The
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.
The effects of clicking the SU DO KU
