The third in my shattered sudoku series (and my personal favorite). If you like this one you can play the first here. and the second here.
Also, I found that using the 'dashed grid' option for playing these shattered puzzles makes the grid feel way less cramped, but your mileage may vary. All feedback is appreciated, and thanks for playing!

Rules:

Place a digit from 1 to 9 in each empty cell. Digits must not repeat within the same row or column of the current grid.

Additionally place 1-9 in each 9-cell region. The 9-cell regions have been broken and rearranged, 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.

The blue lines are 'fragment-sum lines', and meet at fragment borders in the unshattered boxes. The sums of the cells on any given line are equal in each fragment it visits. If a line visits a fragment multiple times, the sum on each visit is counted separately. Different lines may have different sums, and no line visits more than one 9-cell region.

White dots separate cells with consecutive digits.
