This is supposed to be solvable, but I can't find anything. Any ideas?

Sometimes what happens with these games is that there are two possibilities, and if you were to go all the way down one solution you'd find that it required more or less bombs than the other, and you know the total number of bombs that exist in the puzzle so you can then know which solution was right. This isn't practically doable by a human, because you don't have all the information that's covered up.

I'd recommend picking a random square in the middle of that mass of covered squares. If you lose, that sucks and you might say that puzzle was unsolvable, but say hypothetically that you lost on the first click. Was that puzzle solvable? Idk.

This gave me a small existential crisis
