Tips and Tricks:

• This accomplishment requires lots of practice to achieve.
• Play on a window as small as possible, so that you need to move your mouse less.
• When it comes to that fast minesweeping, there is no time to think. Make moves immediately, if you thought too long, just start a new game.
• A lot of fields is not solvable within 8 seconds. It may be helpful to ignore difficult random combinations, and do your best only on those fields, where 1/2 of the grid is uncovered in the first click.
