This is my first galaxies-puzzle. It is one of two final challenge puzzles for my students who worked for one week very successful with variant sudokus - we called it the "mind benders week". In terms of this plattform it is probably somewhere around 2 stars of difficulty. Leave a comment if you like it.

Rules:

Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box.

Divide the grid into galaxies: orthogonally connected groups of cells that have 180 degree rotational symmetry about their centers (marked with a brown dot). All cells must be part of a galaxy; no galaxies overlap.

Digits in galaxies do not repeat and sum to the number in its center (if given).

Digits separated by a white dot are consecutive and must belong to the same galaxy.

The ">" points to the smaller digit of the Domino.
