A Great App

I have used this app sufficiently to tell you that it is great! I have played numerous puzzles from ‘easy’ to ‘insane’ and found them all to work perfectly.
I have input my own puzzles, copied from newspapers and the web, and the program has told me when I have put in the wrong numbers. Again, copied puzzles work fine in this program. I found it a very easy program to get into and yet able to put your own difficult puzzles into.
I really don’t understand the few reviews that say they don’t like it.
