Logic Masters Deutschland e.V.

Normal sudoku rules apply. Blue lines follow at least one of the following properties:
1) German Whisper - Adjacent digits differ by at least 5
2) Renban - The set of digits forms a consecutive sequence, not necessarily in order
3) Parity Swap - Adjacent digits are of different parity (even/odd)
There must be at least 1 of each line type.

In cages, digits sum to the total in the corner. Gray circles contain odd digits. Numbers in white circles must appear in the surrounding cells. Green lines are german whispers and purple lines are renbans. Cells connected by a black dot are in the ratio 2:1
Bonus if you can decode the scribble
