    Just as a clarification, this achievement involves filling in the four corners of the entire board last, and not the corners of a 3x3 square.

    EldritchSSConfirming what Fremontbai said, it's only 4 total cells, at the very corner of the entire puzzle. I kept loading new puzzles through the pause menu until I got one where all 4 spaces were blank, and that worked.

    Sabot FoxJust confirmed that if you are an absolute bonehead and DO finally get a puzzle with four empty corners and accidentally fill in a corner, you can undo your move to blank the corner out, finish the puzzle and then pop in the corners and still get the achievement.

    GoodSmithThis guide is not clear enough. A better clarification would be: it’s the 4 tiny corners, not the 4 large (3x3) corners.

    In Classic Puzzles, keep pausing and choosing New Game until the 4 corners of the board are clear, then complete the puzzle filling in those 4 corners last.

    The Grandmaster difficulty has the least numbers already entered, so is most likely to have the corners empty.

    Pete5683Thank you for this - upvoted as it needs to be Classic, I just completed an Irregular and didn't get it!

    EarthboundXWanna say it took me close to 20 new games until I got a board with all 4 corners empty.

    Start a medium puzzle and keep starting a new puzzle until the four corner squares are empty (corners of the whole board). Complete the rest of the puzzle and enter the number in the corner squares last to complete the puzzle.

    Once you’ve completed the puzzle and backed out to the main menu, the achievement will unlock.
