INVALID MINE

Invalid Mine

If a mine were to be placed into the highlighted cell, it would satisfy the requirements of the hazard cell at C5-R3, which in turn would mean that cells C4-R2 and C4-R4 would have to be cleared. This would leave the hazard cell at C3-R3 with no way of satisfying its requirement for two additional mines. It follows then that a mine must not be placed into the highlighted cell.
