Making a true flash version of Minesweeper is a tricky process to stay true to the original but avoiding any copyright issues. I think I have found a balance of the two, throwing in a unique control scheme to make the game work in flash, adding animation and sound effects, and some special programming designed to cut down on the number of luck-based losses.

Instructions

Press M to mute/unmute the explosion
Press P to pause/unpause the game (also exits custom menu if you clicked by accident)
Click to reveal a square. If it’s a mine, you lose. If it’s a blank square (as your first will always be), it will reveal the adjacent squares.
If you have right-click enabled, click on a non-revealed square to flag it as a bomb. If you click on a revealed square with the correct number of flags around it, you will reveal the adjacent squares (aka superclick).
