User reviews

ONE change needed.

While it would be nice to make the pencil marks go away when redundant (i.e. when I put in a 2 correctly, all “2” pencil marks in the row and column are automatically removed); there’s one thing this app desperately needs to fix. PLEASE move the “hint” button row further away from the number selection row. Put it on top even. It’s so frustrating going to enter an 8 or 9 and accidentally getting another number solved for me. Please.
