Normal sudoku rules apply.

Divide the grid into galaxies: orthogonally connected groups of cells that have 180 degree rotational symmetry about their centers (marked by a small dot). All cells must be part of a galaxy; no galaxies overlap and digits may not repeat within a galaxy.

Some galaxies contain Black Holes at their centers. A Black Hole's value is the sum of digits in cells that touch its dot. For example, the value of a Black Hole made by a galaxy dot on a cell edge would be the sum of digits in that domino. The set of Black Hole values must form a consecutive, non-repeating sequence.

Additionally, the Galactic Census requires that all galaxies with at least THREE cells must report their star system count (the sum of digits in the galaxy).

The grey cells bordering the grid are intended for note-taking.
