Normal sudoku rules apply.

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

Grey Dots mark "renban" galaxies: those with two or more cells, whose digits form an unbroken consecutive sequence in any order. White dots mark galaxies of either a single cell, or whose digits do NOT form a sequence. Digits may not repeat within a galaxy.

As per Galactic Map Standards: All galaxies with at least TWO cells indicate their SMALLEST digit with a diamond icon. All galaxies with at least SIX cells indicate their LARGEST digit with a circle icon.

The nine cells marked with "sun" symbols contain the digits 1-9 once each.

Cells a chess knight's move apart must not contain the same digit.
