It is difficult to explain: column 1: 2 (to the right) in row 11, 4 starts in row 18, 1 in row 24; column 2: 3 (to the right) in row 17, 3 (to the right) in row 23; column 3: 4 starts in row 21 (looks like a cross); column 6: 4 starts in row 22. I hope that will help you.
Thx for the help Kika, but it always baffles me how people cannot give clear tips. For example I only figured what 3 (to the right) means after I have solved. Giving tips/solutions is a f***** no brainer. Just give coordinates of black dots. Fir example say first number is row, 2nd is column. That would mean the 2 dots in row 25 are 25,6 and 25,22. If more dots are together just write 23,2-4. How hard can it be.

column 3: 4 starts in row 21 (looks like a cross);
column 6: 4 starts in row 22.
I hope that will help you.
