Normal sudoku rules apply. Digits along the palindrome lines must read the same forward and backwards. There are three different-shaped clone regions. Digits that appear in one part of a clone must appear in exactly the same position in the other part. Digits in a cage must sum to the little number in the upper left, and may not repeat in the cage. There is one, three-cell thermometer. Digits on the thermometer must strictly increase from the bulb end. Comments welcome!
Solution code: First row of puzzle, and fourth column of puzzle (read top to bottom). Enter as a string of 18 digits, no spaces.

Sehr gut zum Einstieg ins klonen von Regionen geeignet! :D
Besten Dank an PDN
** Sehr gut. Und mit Ihrer Palindromerfahrung sollte das für Sie kein Problem gewesen sein!
