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.

Loved the excellent puzzles in this test. Thanks, Prasanna for these puzzles. Special thanks to Swaroop and other contributors for Penpa updates to make it perfect for online solving.
