Play on SudokuPad!
Normal sudoku rules apply.
Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 cluster of cells is entirely shaded or unshaded. Digits orthogonally along shaded cells must be increasing or decreasing, with 1 and 9 reversing the direction.
A digit on an arrow indicates how many shaded cells are in the direction of the arrow, not including the arrow cell.
Digits separated by an X sum to 10.

Lösungscode: Shaded cells in Column 2, top to bottom

Great puzzle! I didn't fully understand what you meant with "orthogonally along" at first
Thanks for sharing
