It is so important to mark the cells which cannot be the center of a square. Doing this will cause a chain reaction, especially at the edges of the grid. The squares cannot intersect, so for a particular star, let’s say there is 3 possibilities for the center of the square, you can take this as a starting point. If all 3 possible squares with these 3 possible centers are covering one other star in all cases, than you can mark all other possible centers for that other star as empty. All about this type is to mark the cells that cannot be a center, and then you can watch the domino effect 🙂
I’m having a lot of trouble getting this one started. No progress so far.
