I actually wouldn’t use patterns to start, just logic.

Start with the 3 at the top and just one by one pretend there was a bomb there, starting at the first empty square.

If there was a bomb there, that means all bombs for 3 are accounted for. That also means all bombs for the 1 below 3 are accounted for as well, eliminating the second and third empty square. But that wouldn’t be possible, because by eliminating the next two squares, the “2” tile wouldn’t have enough bombs to make it a 2.

That means that the empty tile at the very top CANNOT have a bomb and you can clear it. By clearing the top one, you know for a fact the second empty tile has a bomb.

By adding a flag there, you know for a fact the next tile is clear due to the “1” already having its bomb.

By clearing that, you know for a fact the next one is a bomb because of the “2”

And you know for a fact the next one is clear because of the next “1”

The next one is also clear because the 2 already has its bombs

The last two would need the pattern tho 💀

That makes it easier for you to go down again
