Sandwich Sudoku - Determine X
(Published on 31. May 2020, 13:43 by Sfayne)
Normal Sudoku rules apply.
Sandwich rule apply - The numbers outside the grid represent the sum of all the the digits between 1 and 9 in that row or column.
X is always the same and needs to be determined.
The "X±1" symbol means that the number for that row or column is equal to either exactly X+1 or X-1. For example, if X = 14, the value for that row would be either 13 or 15.
Similarly, "X±2" means the value for that row or column is exactly X+2 or X-2.
Solution code: Row 8 followed by Column 8

@Hasenvogel, ich vermute, dass der Autor des Deutschen nicht mächtig ist.

Ich fand es schwer.
Ich konnte den Wert von X zwar eingrenzen, es blieben aber zwei Möglichkeiten übrig. Dann ging es nur mit T&E weiter. Hab ich was übersehen?

Es gelten die üblichen Sudoku-Regeln.
Sandwich-Regel: Die Werte am Rande stellen die Summe der Ziffern zwischen der 1 und der 9 dar in der entsprechenden Spalte oder Reihe.
Der Wert von 'X' bleibt konstant und bleibt dem/der LöserIn als Aufgabe überlassen.
Das Symbol "X±1" bedeutet, daß der Hinweis für jene Spalte oder Reihe entweder gleich X+1 oder X-1 ist. Zum Beispiel würde der Wert 13 oder 15 sein wenn X = 14 ist.
Ähnliches trifft auch für "X±2" zu: der Wert ist entweder X+2 oder X-2.

No more than 3 stars for difficulty (for me 2.5)
But in any case you should not worry about it.
After a certain number of correct solvings this rating will be automatically changed from your initial one to the one given by the solvers.

Hi everyone. As this is my first puzzle, feedback is well appreciated.
I was quite hesitant about which rating I should put so please tell me if you believe 3 stars would be more appropriate than 4.
Motivated German speakers are welcome to translate the rule set so that I can edit it for German solvers.
I hope you enjoy the puzzle!
