Yesterday I tried minesweeper for real, for the first time. It's one of those games bundled with Windows, that I've never really played for more than a few seconds since I never had the patience to learn it. But somehow I decided to give it a go, so I found a tutorial on Youtube and 15 seconds later I got the basics. I played a few games on basic before quitting and today I tried on advanced but I'm stuck so I was hoping for some help.

I'm really cautious about making a move, since you can't save in between two moves but only between two sessions.

Something that bothers me is the mine located in the upper left corner. How do you know where it's located? If it's on the upper tile the 1 tile is only located next to one, and the 3 tile is also located next to three mines as well so it could be there. But the same is the case if the mine is located on the tile below, so how do you know where it is?
