Welcome to the Den, drock. I would like to direct your attention to rules of this forum (see "Important: READ BEFORE POSTING" at the top). Perform a search whenever you post a puzzle that you have not created (especially for oldies like this one). That way we ensure that you and everybody else always gets fresh puzzles and you don't have to read the same puzzle each week. For instance, search for "111221" and you'll find this posted many times. Actually, it is posted almost 20 times thus sharing the 1st place as the most repeated puzzle together with Two Doors puzzle.
Thread locked.
