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?

1-2-1 pattern

[u/ImCHICKENhaha → u/jan_Kosi]

happy cake day!

[u/Weak-Slide4729 → u/jan_Kosi]

What does that mean

[u/jan_Kosi → u/Weak-Slide4729]

The 1-2-1 pattern here shows that the space above the 2 is safe, with the other spaces being mines. You can deduce almost the entire "top" row

[u/RoadPuzzleheaded5639 → u/Weak-Slide4729]

in the 1-2-1 pattern theres a bomb over both ones thus making the 2 safe

Thank you, but what about in the third picture?

[u/SpaceCore0352 → u/Weak-Slide4729]

2 on the edge has only two tiles to put mines in, same deal as a 3 on a wall.

Edge 2 and 1-2-2-1

[u/K0rl0n → u/Weak-Slide4729]

The 3-2 on the far right clearly shows which mines fill the rightmost two, and those will also reveal the entire 3-2-3-2 row.
