Hi all - I absolutely *love* this site and have saved it as my home page. But lately, I'm getting headaches when I play and having difficulty solving even the easy puzzles. Didn't there used to be darker gridlines that separated the blocks of numbers (i.e., 9 numbers per block in a 3x3 grid of these blocks)? If yes, can they be restored? And if not, can they be added?
Thanks in advance for your help!
