Much like the other achievements on this game, Unless you have a really good memory (Count me out of that category) The best way to complete any board on this game is to fail the game by finding a mine, then click on the "View Board" button and use your smartphone or other camera device and take a photo.
Then click on the "Back" arrow and then click on the "Reply Same Board" button. Then just use the photo you took to see where the Mines are.
Happy Achievement Hunting. :-)
