Logic Masters Deutschland e.V.

This is an improved and significantly lighter variation of the Hamburg Puzzle. The aim was to create a nicer, more fluid solution. In the old version, the middlegame was very tricky and not very elegant. I hope I succeeded. Difficulty for most is just under 2 stars I guess. Have fun!.

The city limits are drawn as a green German Whisper line. The arrow runs along the river Elbe as it flows through Hamburg, from the arrowhead to the sum ovaloid where the river widens sharply.

Hamburg is divided into 7 districts, realized here by the 7 killer cages. The "X" in Hamburg-Mitte marks the position of the town hall and adds up to 10. At the "V" north of it is the airport, added up to 5. From the "X" on the western edge below the Elbe begins the "Altes Land", the cultural landscape famous for its fruit growing also adds up to 10.

Rules

1. Normal sudoku rules apply.
2. Killer: Digits in a cage cannot repeat and must sum to the clue in the top left corner of the cage (if given).
3. German Whisper: Adjacent digits along a green German Whispers line must have a difference of at least 5
4. Arrow: Digits along the arrow sum up to the 2-digit number in the pill.
5. X:Adjacent cells connected with an V must sum to 5, with X to 10. Not all possible X and V are given.
