X-sums Parity Confetti
(Published on 24. January 2022, 08:32 by Playmaker6174)
(maybe next time I'll touch something else besides these parity lines :P)
Rules:
- Normal Sudoku rules apply: every row, column and 3x3 box contains digits from 1 to 9 each once.
- A clue outside the grid (green highlighted) shows the total of the first X cells from its corresponding direction, where X is the value of the first cell.
- Numbers along a gray line (which can be either single digit or two-digit number) must have the same parity (i.e. all odds or all evens), and they also form a set of non-repeating consecutive numbers in terms of their respective parity in any order.
So for example, a 3 cells line if it's all odd then some configurations can be like 3-7-5, 11-9-7, 23-21-25...
(Let me know if someone here can provide more extra link[s] for this puzzle; answer check in penpa will be activated once the outside clues are filled as well, outside clues are filled by 'number' mode)
Puzzle:
Good luck and have fun solving!
Solution code: Row 7 (left to right) and column 4 (top to bottom) in sudoku grid, 18 digits long with no space

Thank you again for more lovely feedbacks, I'm happy that everyone had great fun as well :)
@mathpesto: Thank you very much for your efforts and I'm glad you're interested too! When I looked at the clues again, I realized some limitations that F-puzzle and CTC app have compared to Penpa+, since two-digit numbers may be big problems when it comes to entering the numbers in the clue, so I may want to reconsider adding link options again (maybe you can enter number with text option during solving in F-puzzle instead).

I haven't had the chance yet to try out this puzzle, but it looks fascinating!
I saw your request at the bottom... I've recently been constructing various puzzles with clues escaping the grid. I haven't found a perfect way to do so on F-Puzzles other than expanding the grid size and adjusting the regions; the downside is you have to turn off the conflict highlighter. Here's a version of your puzzle on F-Puzzles if you want to use it:

This is an amazing puzzle! Unfortunately I broke it at some point and I have no idea where it went wrong.
I hope I'll be able to solve it in a 2nd attempt.
