Regional Differences - Trainingsrätsel
(Published on 4. April 2022, 20:15 by glum_hippo)
Standard Sudoku rules are in effect. Each row, column, and 3x3 box must contain the digits 1-9 exactly once each.
Assign a number from 1 to 9 to each 3x3 box, such that no two boxes are assigned to the same number. Within each box, all pairs of orthogonally neighboring digits whose difference corresponds to that number are marked with a diamond.
Link for online solving in F-puzzles or the CtC-App.
A previously unknown (to me) forerunner from Richard is here, and the originator of the rule set seems to be Bram de Laat. Thanks to Realshaggy for making me aware of these precedents, and for some guidance on formulating the rule set.
Solution code: The 7th row, followed by the 4th column (18 digits total).

so it is called super consecutive. thanks Realshaggy. but I think it can be dated far before 2018. I remember seeing one before 2016. It's an very OG variant.

Superconsecutive is in Richards SVS #249, Puzzle ID 2YB. He gives WSC 2018 as his source.

it actually remind me of another ruleset in gp(maybe, or some other contest). something like super consecutive(Chinglish). but in that one, the difference within a box is a circled digit.
