A Game of Two Halves
(Published on 16. July 2024, 12:34 by Abdul the Killer)
Standard Sudoku rules apply.
SHADING: In the completed grid, cells containing numbers exactly one greater than an immediate neighbour (diagonal or orthogonal) within their box are shaded (and otherwise unshaded).
The shading must have 90° rotational symmetry.
DAISIES: Values in cells with daisies give the number of shaded cells in the (up to 8) surrounding cells. All possible daisies are given.
Solution code: Row 1

Hiyaaa I've done several of your puzzles before and find them really fun! I'm wondering with this puzzle and would like some clarification, what does the 90 degree symmetry exactly signify/look like? An image of a small grid with the rule in effect would be splendid if you're able to do that. Thank youu :)
---Sure. You can see examples of this type of symmetry in my puzzles: https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000ECF and https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000CJH. Good luck. ---ATK

Got stuck twice with a conflict near the end and had to give up for the time being, but enjoyed it nonetheless :).
---Glad to know you're sticking with it. Good luck! ---ATK

It took me a long time to be able to do your shading puzzles without screwing up, but I'm getting the hang of them and I really like them.
---Really nice to hear, I swear that even after more than 90 puzzles I still find things that had previously escaped me. Thanks. ---ATK

Interesting twist. Enjoyed this very much. Thank you for sharing.
---Thanks for saying. I'm surprised that these "daisies" work at all, but they obviously do.---ATK
