    Default How clock ciphers work

    Can anybody steer me to some good information on how clock ciphers work? I've seen the phrase pop up several times in these forums and thought I'd ask. I'm working on a puzzle for a geocache right now that uses a clock cipher but can't seem to figure what to do with what I've got.

    Welcome to Tweleve!
    I don't think there is a good website that contains the info you are looking for. There are a lot of mentions of clock ciphers here, because there was a hunt called Secrets of the Alchemist Dar, and a lot of people thought there was a clock cipher being used in it.

    My understanding is that you set the alphabet around the clock, removing (or combining I/J and P/Q) 2 letters so that you have a 24 letter alphabet. There would be 2 letters per number around the clock, and the hands of the clock would point to the letter needed. The hour hand could indicate the first half of the alphabet, and the minute hand the second half, or vice versa.

    I don't know if this helps you or not. There are many possible variations for this cipher, especially if a keyword is used, or a scrambled alphabet.

    I hope you stick around here after you figure out your geocache!

    I'll definitely be hanging around. Actually, I just referred a friend to the site as well. This stuff is right up my alley!

    Your description of a clock cipher doesn't sound applicable to my problem. I've been given a bunch of "move forward" commands with numbers and occasional "return to zero" and "start time" commands. I should be ending up with a set of lat/long coordinates....

    The original code was a series of ASCII numbers which I decoded to get the following:



    Super congrats, you have just solved half of five stars! You are nearly there, don’t give up now! Next, we need to synchronize our clocks and resynchronize as told: First ABC, then 1, 2, 3.

    “Start time” (st) is 0. Don’t forget your hint (x = 5), elapsed hours 724, do not “reset to zero” (rtz), until told to do so!

    Keep solving your puzzle,
