mentioned there are different Graded puzzles:

Very Easy, Easy, Medium, Hard, Very Hard or Anonymous.

I can't generate "Very Easy" & "Very Hard" puzzles using the trial version of this program.

Name: Sudoku 1.0 (version 1.00.03)

Pls advise

You do it the same way as you generate Easy and Hard ones, but with the Ctrl button held down.
