MinesWeeper Cheat

Reveal Mines
With your cursor inside the minesweeper window type "XYZZY" then press Shift-Enter and Enter. A white dot should appear in the upper-left corner of the screen. If it turns black, your cursor is resting on a mine.

Note: This trick works best if your Windows background is black. Also note that code will not work in Windows 95 or Windows NT.Sound Effects

Stop the Clock
While playing, hold down the left and right mouse buttons and you should see a 3x3 square imprint on the board. Next hit the ESC key while holding down both mouse buttons, and the timer is stopped!

Cheat: Freeze Time

There’s an easy-to-execute glitch/cheat in Minesweeper that will stop the game’s time so you can take your time completing each puzzle (hence getting the high score!) To do so, start a new game and then quickly hit the Windows key and the D key at the same time to minimize the game to the bar below (and any other program). Then, maximize the game again and the clock will be permanently frozen.
