Actually, now that I think about it, you might have been asking what to do with the lottery channel answer. To clarify — there’s a code near the door with another Morse machine. The code itself doesn’t fully make sense at first because some symbols are replaced with shapes instead of letters. The goal of the other puzzles is to collect the “rules,” as I call them — clues that show which letter corresponds to which symbol or letter. Once you’ve gathered all of them, you can use that knowledge to solve the final door puzzle.
