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 unflagged cells contain a mine. Solving a MINESWEEPER puzzle is a mouse only operation. A single click in any PENDING cell will convert that cell to a CLEAR 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 PENDING cell.
