I have no idea what happened... I think I did it wrong!
I was painfully slowly adding and chipping away again some but very few options and then stared at the mostly blank grid for an eternity, added some more and removed some more again and I must have stared at it for so long that the autopilot kicked in or something, as I regained consciousness I had to fill in just eight or nine more digits. And now left with a filled grid... and still no idea how to solve that thing.

a little clarification (and somewhat of a spoiler): there are no overlapping Vs and dots.
