Go to the game menu and put the difficulty on custom and type 24 in the height, 30 in the width and 10 in the mines. It will then be very easy.

HexCheat:

Goto the Windows Directory then look for a file named "winmine.ini". Open this up using wordpad. you will see the lines.

[Minesweeper]
Difficulty=0
Height=8
Width=8
Mines=10
Mark=1
Color=1
Xpos=80
Ypos=78
Time1=999
Time2=999
Time3=999
Name1=Anonymous
Name2=Anonymous
Name3=Anonymous

If u edit the 999 to a time like 10 for time 1, then put your name in for the name 1, whenu click on best times u will see your time listed with your name. I have completed this in 2 seconds and the other levels in 15 and 30. I must have the record for cheating.

High score in minesweeper:

To change the high score in minesweeper you have to open the file "winmine.ini". once you have opened it change the name and time given at the bottom of the file. The next time you open minesweeper your name with the best time will be displayed

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. This trick works best if your Windows background is black.

Sound Effects:

For sound effects, add the line "SOUND=3" to WINMINE.INI

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
