Location: United Kingdom		In Series Sudoku, is it true, from a solving point of view, that the order of the series has no significance and we simply have to ensure that the shaded cells contain a digit contained in the set of given numbers?

The repetition of digits and sequence of digits does not matter as long as those digits appear in shaded cells. The '1' is repeated because the theme is 'Pi', the givens are shaped like the symbol 'Pi' and the numbers outside represent the value of 'Pi'.

I find it difficult to distinguish the gray lines and arrows on hidden skyscrapers and diagonal consecutive. Could they be a bit darker on the test grids?

Thanks !

Changed the arrows to 40% black (it was 20% earlier). Let me know if this is better.

Thanks, but I deserve 0 credit for that.

I would not say it is easy for an average solver, but I've seen ones that are a lot tougher than this one. Took me around 8 minutes for this one (and solvable logically, without a need for guesswork), but I am not a 'top solver' in Windoku :-)

I hope you use the Windoku 'extra-regions' rule: (Each set of same-coloured cells contains numbers 1-9 apart from the nine 3x3 boxes and four 3x3 regions)

In the 9th box: you have a pair 28 next to the 5 (edges). Then at R9C7 in can only be 4 or 7. Then you can place the 1 in row 8 (considering that there isn't edge between R9C67, then 4 can't be placed at R9C6 ). You can place 1 and 4 in 8th box, then the 9 in row 8, etc...

I like how the N=3 works (I think that perhaps I'm the inventor of this variant?): You have to "think" digits into 3 groups: 1-4-7, 2-5-8 and 3-6-9. And in these groups 4, 5 and 6 play a central role.
Each N has it's own logic, perhaps you have to think about it for each N before the test

To proceed little further, check 20 at 3rd block can contain only 956, to avoid 56 coming consecutive, 9 has to be inbetween them at R1C8

Location: China		I think some hints in "sum or product frame" can be removed, like 15 in col5, 18 in row9, 15 in col9, 18 in col1, 10 in row8, 10 in row4, and the puzzle has unique solution too.
But maybe it will make participator much easier to find the point :)

The original puzzle didn't have the 4 inside clues. But then it was much harder. I added those 4 hints after Zoltan's testing, but I didn't check if I should remove some of the outside hints.

The score page has some bugs - points for Linked Mini is not computed for all, motris' row shows 0/18, and some players' score is missing completely. Allow me few hours to make the score page public after I fix the bugs.
