HOW TO PLAY?
--------------
You have to use color to divide the grid into regions in such a way that:
- Each region has exactly 1 black point in it.
- The black point 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.
