Standard sudoku rules apply.

The dots given in the grid are the centers of pointsymmetric galaxies (non-overlapping sets of orthogonally-connected cells). A galaxy must form a line, it cannot branch or cover a 2x2 square. Single-cell galaxies are not allowed. In contrary to a classical galaxy puzzle, not every cell in the grid has to be part of a galaxy. The digits in a galaxy may not repeat.

Consider the first x and last y cells of a galaxy where x is the value of the first and y the value of the last cell. Those x/y cells cannot reach cells outside their galaxy. The number above a dot give the sum of the digits where these groups overlap or the sum of the digits between these groups.
