Galaxies


Translate this site.

Galaxies also known as "Spiral Galaxies" or "Tentai Show" is a logic puzzle with simple rules and challenging solutions.

The rules are simple. You have to divide the grid into regions (galaxies) in such a way that:
- Each region has exactly 1 white circle in it.
- The circle is the center of its rotational symmetry. In other words: If you rotate the region around the circle at 180° you should get the same shape, position and orientation.
- A region cannot be a neighbour to itself

Left click between the dots to connect them. Right click to mark with X. Tip: Shift+Click colors a square.
