    Probably best to use Grandmaster as this will have the least squares filled in originally, and then just keep selecting 'new game' until the 5 squares making up the 'X' in the centre square are free. Make sure you fill these in last!

    Top tip: Don't forget to fill in the squares surrounding the X in the centre square first!

    D0 THE DANCEI did it on an easy puzzle. Definitely does not need to be Grandmaster. I only had to hit refresh 3 times.

    Corn 0nThe CobbI accidentally filled in the X early, but I erased those 5 numbers, finished the rest of the puzzle, then filled in the X again at the end. It still unlocked.

    Also, I don't think the order matters. I did BL → C → TL → TR → BR.

    Use Grandmaster level for this beacause it has the least square filled. You must keep restarting the game until you have at least the five squares in the center free.

    The easiest way to get this achievement is to start a game on Grandmaster. Keep starting a new game until you can make an X pattern in the centre square (see video below)

    Complete the puzzle by entering the puzzle last and the achievement will unlock once you get to the main menu.
