How to solve
- One dot per galaxy: Every region contains exactly one dot, which is its centre.
- Turn it around: Spin a galaxy half a turn around its dot and it covers the same cells.
- Cover the grid: Every cell belongs to exactly one galaxy.
- Mirror pairs: If a cell belongs to a galaxy, the cell opposite it through the dot does too.
