Logic Masters Deutschland e.V.

My second shattered sudoku. If you like this one you can play the first here.
All feedback is appreciated, and thanks for playing!

Rules:
Place the digits 1-9 once each in each row and column of the current grid.

Additionally place 1-9 in each 9-cell region. The 9-cell regions have been broken and shuffled, but the fragments of each region could be reshuffled into a 3x3 box using translation and rotation. No fragment has been placed next to any other fragment of its original box.

Digits in cages sum to the small number in the corner.

Digits separated by a white dot must have a difference of 1.
