Mutated Box Pattern (Finned Bounded Box)
Difficulty E · Depth 4 · Section: Box Logic
Explanation
Improved Description by Not Anon
Pattern found by Scar
The blue cells contain 2-3 mines
The green cells contain one mine.
The finned box will therefore contain 3 or 4 mines
One of these mines goes into the yellow cells
The red cells contain two mines, as three mines is not possible.
The 2 sees the red cells, so the lime crossed cell is safe.
Since we have concluded that the red cells contain two mines, and the yellow cells one mine, we know that the blue and green cells collectively contain three mines as well, and we know that one mine goes into the green cells, so there will be two mines in the blue cells. The 5 sees the blue cells, so the fifth mine goes into the red crossed cell
