Entropy*
(Published on 18. January 2023, 10:17 by AParliamentofOwls)
Normal Sudoku rules apply.
Non-consecutive: No two orthogonally adjacent digits can be consecutive.
Global entropy: let the numbers be divided into three groups (123)(456)(789). In the finished grid, every 2x2 area must contain every group at least once EXCEPT...
Quadruples: Digits in bubbles must appear in the adjacent cells and the entropy rule must NOT be fullfilled in quadruples
Solution code: row 9

Novel idea!

This was super fun. I really enjoyed discovering all the little intricacies of these rule interactions. Thanks for sharing!!

Nicht sicher, ob das beim Lösen klar wird, aber wie verhält es sich mit der Entropy-Regel und unvollständigen Quadraten? z.B. R4Z9+R5Z89 werden durch ein Quadruple "eingeschnitten". Müssen die drei übrigen Ziffern der Entropie-Regel folgen oder nicht?
(Not sure if it'll become clear whilst solving. Are the Entropy rules still in play when a 2x2 area is incomplete, because it's cut of by a quadruple (e.g. R4C9/R5C89, do they still have to follow entropy rules?)

Nice concept, very entertaining puzzle.
The disruption of global entropy around the quads added a very nice twist! Thanks.

Beautiful puzzle, I really enjoyed the solve path. Can I suggest rewording the LMD English wording to specify that you mean orthogonal adjacency? It says so on CTC, but not here. Thanks for such a lovely puzzle! :)

Very nice puzzle! I was afraid it wouldn't resolve toward the end, but at the last step I realized that I had completely forgotten about the nonconsecutive constraint :) Thank you for sharing!
