A MINESWEEPER puzzle consists of a square or rectangular grid in which a number of mines have been laid. Some of the cells contain a hazard flag which has a
number indicating how many of the adjacent cells (horizontally, vertically and diagonally) contain a mine. To solve the puzzle, you must determine which of the
un-flagged cells contain a mine. Each puzzle has a unique solution and no guessing is required to reach a correct solution. Puzzles can be built either manually or
automatically in sizes from 6x6 up to 14x14.
Solving a MINESWEEPER puzzle is a mouse only operation. A single click in any DARK cell will convert that cell to a NO-MINE cell which has a default
color of white. A second click will convert it to a MINE cell, and one more click will convert it back to a DARK cell.
