First Turn: You can never lose on the first turn of Minesweeper- the first click will never be a mine. Make it count!
Paint By Numbers: Each number (that is, number of mines surrounding the square) has a different color. 1 is blue, 2 is green, 3 is red, 4 is dark blue, 5 is dark red, 6 is blue-green, 7 is purple, and 8 is black. 8 is the maximum amount of mines that can surround a square. Now isn't that some useless information?
