I try to make a classic chaos construction puzzle, and here it is. The difficulty may be around 3.5*. Hope you like it!

Rules:

• Sudoku: Place the digits 1-9 once each into every row, column, and region.
• Chaos Construction: Divide the grid into 9 regions, each containing 9 orthogonally connected cells. Some region borders are already drawn.
• Arrows: The digit in a cell containing an arrow indicates how many consecutive cells in the arrow’s direction — starting from the next cell — belong to the same region as the arrow cell. This count stops at the first region border seen and does not include the arrow cell itself. Not all possible arrows are given.
• German Whispers: Adjacent digits along a green line must differ by at least 5.

Example:

In this example puzzle, adjacent digits along a German Whisper line must differ by at least 3. Try example puzzle
