    Avid Minesweeper fans will immediately recognize that pattern.

    Your opportunity to do this achievement (and 1-2-1) will come when you click a tile in a large area of no mines, and opens a large swath of the board. When this occurs, look at the edges of the newly opened area and look for those four tiles in order and in a straight line, 1-2-2-1. In most (not all) cases, the mines are in the tiles directly adjacent to the "2" tiles, and the safe tiles are adjacent to the "1" tiles.

    When you see that pattern, immediately flag the tiles in front of the "2" tiles, and normal click next to the "1" tiles. In most cases, this will be a safe move. If the pattern is in the middle, though, you may hit a bomb due to a quirk of the bomb layout. If it does, just try again. Once you've successfully done this 10 times, the achievement will unlock.

    If you want to get this quickly, find a puzzle where the pattern exists. Do the method above to flag and click the proper tiles, then deliberately fail the game. When the option popup comes up, click "Play Same Puzzle." Since you know where the pattern is, you'll be able to click right to it and repeat. Do this 10 times, achievement unlocked.

    EDIT: JonnyBlazin5 correctly points out that you don't have to flag the mines, just click/clear the tiles to either side of them. I find it a help when playing Minesweeper to flag the mines, but for this achievement it is not necessary to do so.

    EDIT: Reabo made a great YouTube video illustrating this solution. Thanks!

    EDIT: CanadaAckis points out that the achievement now requires 20 repetitions instead of 10. Thanks for the heads-up. And thanks MSFT for changing the rules on us... :(

    Homunculus Furyit seems that mine has glitched as well. As I understand it you have to chord first unlike the WP version. I've done this well over 10 times. I even have a board set up to do 1-2-1 and 1-2-2-1 at the same time. Oh well it's not like i'll get all the achievements in this anyways.

    DivxKillerI also seem to have trouble unlocking this and the 1-2-1 achievement. I have the Windows Phone Version.

    KeysworedI'm also gonna point out the 1 2 2 1 combination has to be in a straight line. I've tried to get it when there on corners and such and it doesn't unlock.

    PrimeBigTimeJust FYI regarding "When you see that pattern, immediately flag the tiles in front of the "2" tiles, and normal click next to the "1" tiles." You don't need to flag tiles. Just click in front of the 1's. Also, if this is in a straight line, the bombs will always be in front of the 2's. There is no other way that they can be set up.

    HolyHalfDeadWhen the pattern 1-2-2-1 is revealed, uncover the 2 safe tiles within 3 seconds... 10 times.

    I can confirm that not only do you need to get 1-2-2-1 in a straight line, but there must be four uncovered squares alongside the line. If one of those squares is already uncovered, leaving you with just one square to uncover it does not count, because you need to "uncover 2 safe tiles".

    AckisUpvote for you, but you need to do it 20 times now, not 10.

    THEbigBROWNIEIf you find a map with the pattern, you can do it, then hit a mine on purpose, and hit restart map, and each time still counts. It seems harder to find a map with the pattern then actually doing it.

    fighterx93chippNot sure what I’m doing wrong but it seems to not be tracking this properly. I uncover the two non mine tiles and do it 20 times but then go to check progress and it still says 0/20
