This is the 7th part of the series of dividing areas.
"邹子" Sudoku
According to the following rules, the grid is divided into 9 different rigions, each regions contains 9 cells:
1.Fill in a number from 1-9 in each region, and make each row, column and region have no repeated numbers;
2. In the same region, if the difference between the numbers of two orthogonal adjacent cells is 2, mark the larger number between them.
3. In different regions, if the difference between two orthogonally adjacent cell numbers is 1, mark the larger number between them.
4. All eligible numbers have been marked.

Solution code: In the reading direction (from top to bottom, from left to right), the content of the irregular area where R4C3 is located, and the content of the irregular area where R9C6 is located, a total of 18 grids. (for example, in the example, the content of the irregular area where R3C5 and R4C4 are located: 436251235614).

If you have a good idea, you can also make similar puzzles like SudokuExplorer, and look forward to your more exciting puzzles!

@cdwg2000 Yeah, I'm working on it, they're a lot of fun and probably gave me inspiration for a puzzle I want to create as well :)

Erhöhen Sie die Übersetzung der deutschen Version. Meine Muttersprache ist Chinesisch. Wenn es eine falsche Übersetzung gibt, helfen Sie mir bitte, darauf hinzuweisen.

BTW, there is a mistake in the solution code, it must read 18 instead of 14.

Solution code:
In Leserichtung (von oben nach unten, von links nach rechts) der Inhalt des Gebiets, in dem sich Z4S3 befindet, und der Inhalt des Gebiets, in dem sich Z9S6 befindet, insgesamt 18 Ziffern. (Im Beispiel mit Z3S5 und Z4S4: 436251235614).

Unterteilen Sie das Gitter in 9 Gebiete mit jeweils 9 Zellen.
Tragen Sie dann die Zahlen von 1 bis 9 so in das Diagramm ein, dass in jeder Zeile, jeder Spalte und jedem Gebiet jede Zahl genau einmal vorkommt.
Wenn die Differenz zwischen zwei orthogonal benachbarten Zahlen im selben Gebiet 2 beträgt oder wenn die Differenz zwischen zwei orthogonal benachbarten Zahlen in verschiedenen Gebieten 1 beträgt, steht die größere Zahl auf der Grenze dazwischen. Alle derartigen Differenzen sind gegeben.

This is a German translation of the rules. Feel free to add it to the German version of the puzzle.
Maybe a native English speaker could also improve the English version? Or maybe someone has an idea to improve my translation.

@DiMono
Thank you for your feedback! When I tested it, I thought it was 3.5-4.5 stars. Dividing regions may be difficult. It takes enough patience to complete it and make full use of "negative constraints" and "differences." I am very glad that you finally succeeded in the challenge.

This is a difficult constraint to keep straight. Definitely a 5/5 for me.
