Hi, can you please help me with a hint for Star Battle 2? I solved 1 and 3 but I could not figured out the trick for 2.
Note the four L shaped corner regions. These must have 8 stars in total. The first and last rows and columns must also have 8 stars in total. This gives a few deductions, check it out. If you still don't have it I (or someone else) can explain further.
Prasanna mentioned that I should link my solve of this contest here, so if you're curious what a top-level perspective (I was third) of one of these looks like, I've got one. https://youtu.be/lDoMcZzE7gM
