Rules:
Normal sudoku rules apply.
-It must be determined whether each white dot is a kropki dot or the centre of a galaxy.
-KROPKI: The two digits joined by a white kropki dot have a difference indicated by the number on the kropki dot.
-GALAXIES: A galaxy is a group of orthogonally connected cells, that has the white dot at its centre and is rotationally symmetrical through 180 degrees.
-The number on the central dot of a galaxy indicates the number of cells (N) in the galaxy. This galaxy must contain all the digits from 1 to N.
-Galaxies cannot share cells with any other galaxies or cells joined by a kropki dot.
-Galaxies also function similarly to region sum lines; digits within each 3x3 box sum to the same amount if they are within the same galaxy. This region sum may be different for different galaxies.
Lösungscode: Row 6 followed by row 9.

Impressive and cunning.

This was a brilliant and slick construction. Remarkable that you managed to get a unique solution with just 4s and 8s in the circles.
There were some really nice global deductions to realise, and lots of small aha moments along the way too. Lots of fun all the way through!

Fantastic puzzle with some unusual constraints. Not too hard to get the first galaxies, and very impressing how the rest of the grid unfolded. Thank you so much for sharing this lovely masterpiece!
