I am new here. May I submit a puzzle to test your software ?
6 . . | 2 8 . | . . 4
5 1 . | . . . | . . .
. 8 . | . . . | . 9 .
-----|------|------
. 4 . | 3 . . | . 8 .
. 9 . | . 5 . | . 1 .
. 2 . | . . 7 | . 6 .
-----|------|------
. 3 . | . . . | . 4 .
. . . | . . . | . 5 8
1 . . | . 6 9 | . . 7
When solving manually (my preferred way) after a certain point one can get on manually only by trial and error.
I could tell which cell to set to proceed to the end, but I am curious to see how your software works... |

| Your puzzle can be solved with Naked/Hidden Singles and Naked Pairs. You need to restart from the beginning and try again. |
