I'm stuck on this puzzle. I have the last column (65) correct--green arrow. I should be able to complete column 64 just from that. Apparently my problem is in the first 10 or12 rows, but I see no solution for this column. The problem is specifically with placing the "blue" dots (one blue, then 3 blues) in between. The black squares, which form the borders in this section, all show correct when I do a puzzle check. Am I blind, or is there a problem with this puzzle???
