Minesweeper - TV game

"Minesweeper" is originally a PC game that comes along with the Windows bundle. For our design, there are 15 x 10 cells on the game board. At first, all 150 cells are covered, and the player can left-click the PS/2 mouse on a destined cell to uncover it, or right-click to mark the cell with a flag – a reminder to the player that the cell is possibly taken by a mine.
