Sum Sudoku
Solve online in Penpa+ (thx Whoever!)
Apply classic sudoku rules. The grey coloured columns divide each row in three parts: white (4 cells), grey (3 cells) and white again (2 cells). Consider the digits in the three different parts as numbers of 4, 3 and 2 digits. Clues on the left of the grid are the sum of the three numbers. Example: The sum in row 1 could be formed by 3.624 + 795 + 81 = 4.500.
Solution code: Column 7, followed by column 9.

Removed a too enthusiastic copy-paste-effect. :-)

Wieso gelten hier eigentlich die üblichen Sudokuregeln gleich doppelt? ;)
