Interesting position with a safe square - can you find it?
This was a rare moment where I actually had to think to find it. Can you?
Screenshot is from a solver I found online because I didn't think to take a screenshot until I already opened the safe square.

Top blank square. The two 1’s at the bottom prove it. Bottom 1 has two unknowns. Which means one of them is the bomb. Which means the bottom mystery square can’t be the bomb which means the top square is the bomb.
