Bounded Box Pattern
Difficulty D · Depth 4 · Section: Box Logic
Explanation
Pattern found by: Not Anon
The blue cells contain one mine
The green cells contain 2 mines
The “box” contains between 3 mines
One of these mines goes into the yellow cells
The red cells contain two mines
The 3 sees some of the red cells, that contain 1-2 mines, so the lime crossed cells are safe.
You can also apply this backwards and prove that the cell bottom-right of the 4 is a mine, which simplifies it to a basic box
