 A flagged cell is similar to a covered one, in the way that mines are not triggered when a cell is flagged, and it is impossible to lose through the action of flagging a cell.However, flagging a cell implies that a player thinks there is a mine underneath, which causes the game to deduct an available mine from the display.In order to win the game, players must logically deduce where mines exist through the use of the numbers given by uncovered cells.
