That's not the case. I have come to such situations. And I suppose the program can identify those as well and put the bomb where you didn't click.

I've played that one a lot (hundreds of games on Evil difficulty). So far there's no guessing required after the initial click. Everything can be deducted. Even though some deductions are really hard (you have to go through mine blocks from multiple starting points and multiple hops in order to determine the next safe block).
