I had some problems finding out the location of the last single dots, but it was very nice, thank you.

Had to guess after getting the first 10 dots or so.

HINT:

The logical dot found in the 11th column is part of the 6 set. After that it's really easy to figure out.

Thanks for the hint LeraDraco69.
