How am I supposed to finish the puzzle in the secret bath when there are "x"'s in boxes that need to be changed? I can't change them. Thanks for any help.

Hi suehorse,

You don't need to do anything at all with the X boxes as they appear on the grid. Just ignore them. All you need worry about is the blank squares, and whether they need to be shaded (confirmed) or left blank as they are. Simply left click on a square to shade it. Click again to turn it back to blank. Click and drag to shade multiple squares at a time.
