Palindrome Killer Sudoku
(Eingestellt am 8. August 2020, 23:02 Uhr von udukos)
An area surrounded by a dashed line will be called a cage. Digits may not repeat within a cage. A number in the top left corner of a cage indicates the sum of all the digits in that cage.
The green outline/figure represents a 21-digit palindrome the ends of which have to be deduced (i.e. the first digit and the last digit lie adjacent to each other on the green line).

One last thing. If one flips the image horizontally the result looks like Texas!

Very satisfying at the end.
But beware I do NOT believe this is a 3-star puzzle. I am rating it 5.
Difficulty is very subjective, but I am not exaggerating when I say this is at least one of the top 10 hardest puzzles I have solved in the last 3 months. But it is possible I totally missed some easier ways to solve it. [To be continued in hidden].
