Based off of: Ken Duisenberg's Puzzle of the Week Oct. 15, 2003: Minesweeper Queens
For the puzzle, in the given diagram, the numbered squares are empty, from which the given mines can be attacked by a chess queen. As in standard chess, a queen can attack all eight directions, and only one mine in a single direction.
For example:
Place 5 mines:
1 2 4 3
has 4 solutions, one of them being (x
represents a mine)
+---+---+---+---+---+ | 1 | x | x | x | 2 | +---+---+---+---+---+ | | | x | 4 | | +---+---+---+---+---+ | | | | 3 | x | +---+---+---+---+---+
To get the $\color{green}✓$:
- Place 13 mines in this grid
- Show the steps you took.
+---+---+---+---+---+---+ | | 4 | | 4 | | | +---+---+---+---+---+---+ | 4 | | | | | | +---+---+---+---+---+---+ | | | 6 | | | | +---+---+---+---+---+---+ | 5 | | | | | | +---+---+---+---+---+---+ | | | | 5 | | | +---+---+---+---+---+---+ | 3 | | 4 | | | | +---+---+---+---+---+---+
