Questions regarding WSC round 13 - Linked

[Richard]

All questions regarding WSC round 13 must be asked here.

[Para]

Just a minor note. There's an error in the solution of 13.1A. R4C79 are switched.

[SF2L]

the description says that "there is a row of clues....". does it mean strictly a (horizontal) row or could it be a column? will the circles identify the same row/column in both diagrams? or possibly different rows? or a row and a column?
Will the clues appear in the same order or the order can be inverted?

Thanks! Will be fixed in the next version.

A row is Always horizontal.
Circles will Always have clues for the same column, and if not (Little killer) it is very clear in the competition puzzle.

In the Link example, Outside Parity is non-unique.

Also, could you confirm if all possible circles between two grids are marked? I don't think that has to be the case, but the example has all possible circles marked, so clarification would be nice.

Uniqueness of the example will be fixed in the next version of the IB.

All circles are marked that are necessary to derive a valid solution for the combined grids. It might be possible that on an empty spot a circle can be drawn too.

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.
