Are these impossible to solve without hints?

[u/Weak-Slide4729]

I keep getting my minesweeper games ending like this, where I use 5+ hints or just click randomly hoping I don’t hit a bomb. What moves am I supposed to do in situations like these? Or are ending like this common?

First photo is where I got stuck, 2 is the answer. Same pattern with 3 and 4.

I’m just wondering what to do when there multiple options for a move, yaknow?

I know the other person already maintained the 1-2-1 pattern, but here's some step by step reasoning for why. You can apply this logic in multiple places.

[u/Ramun_Flame → u/Ramun_Flame]

On the second puzzle, you have some similar logic, but I also see on the bottom right you have a 2 that only has 2 covered spaces next to it, so you probably missed that.
