Questions regarding WSC round 13 - Linked

[Richard]

Hi

The rules say, that finding the clues in circles is part of the puzzle.
1. Do I need to fill them with correct numbers? Or is it enough if I leave them empty and have sudokus correctly solved?
2. If I have correct numbers in the circles and they are crossed out, do I still get point for the puzzle if the sudokus are correctly solved?

The circles don't need to be filled. Only the solved sudokus are taken into account to receive points.
