Turtle Sudoku
Inspiration for this type comes from Thorsby.
Solve online in Penpa (Thx SudokuExplorer) or in F-Puzzles or in CtC-App (Thx Nick Smirnov!)
Apply classic sudoku rules.
Clues on the left of the grid indicate the sum of all horizontally and vertically neighbouring digits of the digit 1 in the respective row. Clues above the grid indicate the sum of all horizontally and vertically neighbouring digits of the digit 2 in the respective column.
Solution code: Row 1, followed by column 6.

@SKORP17: Die 1 bzw. 2 zählt nicht mit. Ich glaube, du hast alles richtig verstanden!
Eventuell solltest du deinen Kommentar verstecken, da deine Erkenntnis Teil eines Lösungsansatzes sein könnte...
