Normal sudoku rules apply.
Green lines are German Whisper lines wherein digits must differ by at least 5.
The orange line is a Dutch Whisper line wherein digits must differ by at least 4.
The blue line is a Region Sum line wherein 3x3 box borders divide it into segments with the same sum. There is only 1 region sum line in this grid that spans from r1c3 to r9c7.
The grey line is a palindrome in which digits read the same forwards and backwards. The palindrome in this grid is covering a portion of the german whisper in box 1 that does in fact extend to r3c3 to complete the letter 'C.'
Red lines contain digits of the same parity. There are 2 such lines.
Solution code: Enter Row 6

Nice ideas. In the future, you can use different line thicknesses. Then people will appreciate it more.

Diese sich überlappenden Linien sind sehr verwirrend :-(

You have a 7 in r1c3. It should be a 9.

@Onkel_Dagobert - The overlapping lines add some confusion here, but the region sum line terminates in r1c3, not r1c2 as your solution seems to indicate.
