Today we're going to talk about another common pattern as well as an important critical thinking skill. First up the pattern, this is known colloquially as the one sammich, let's examine:
As you can tell the one sammich is when you have one, two, one in a row. The one sammich will typically yield five pieces of information (for future reference, a piece of information is one known square).
Shown are the three possible places for the twos mines, but which two are correct?
This doesn't work because there are now two mines in the one squares outskirts. If we shift those two mines to the right, then it doesn't work because there are two mines in the other ones outskirts.
This will always be the solution to the one sammich. Unlike the three corner, there are only three possible mine layouts and only this one works.
Highlighted are the five pieces of information that you are typically guaranteed from the one sammich. Here you got quite a bit more information. The two twos to the lower left of the left one were gained form this. In addition we were given a solved two in the middle.
An important thing when examining a board is to consider numbers not for what they're shown as, but what they functionally are. The following scenario uses a one sammich to highlight this.
This might not look like a one sammich, but make no mistake, it's identical to the above scenario.
You see, because the two already has a mine touching it, it's functionally just a one as shown here.
That makes this the correct solution.
Once again, we get five pieces of information. This solution gives another solved two for even more information!
As always, here's a minesweeper game won through logic, today set to wesley willis, cause, you know, heinz is america's favorite ketchup
