Galaxies Solving Tips
Galaxies is about ownership: for each square, ask which dot could own it, remembering that owning it means owning its mirror too. New here? Read the rules first.
1. Squares with one owner
For a square, imagine each dot owning it: the mirror square must exist inside the grid and be free. Often only one dot survives. Paint and move on.
2. Every deduction doubles
Painting a square paints its mirror, and that mirror has its own neighbours to think about. Follow the chain across the dot.
3. Edges and corners
Dots near an edge have short reach: a square two steps away on one side needs a free square two steps away on the other. Edge squares therefore often belong to the nearest dot.
4. Connect through the dot
A galaxy must be connected. If a square is yours but the path to your dot would cross another galaxy, the square can't be yours after all.
5. Close regions
When a galaxy's shape is fixed on one side of the dot, the other side is fixed too. Finish it and the surrounding squares lose an owner, which forces them.
Frequently asked questions
Where should I start a Galaxies puzzle?
At squares with only one possible owner: a square whose mirror through every dot but one would fall outside the grid or onto another galaxy's home. Paint it, and its mirror comes with it.
