Spiral Cipher Clocks
To make a cipher clock even harder you may want to create a spiral cipher that gives
each character on your cipher clock multiple values. The picture below shows a spiral
cipher clock with letters A-Z, a comma, period, and a space. Each character on the
clock can be represented with a number. In the first spiral the letter A is equal
to 1. B is equal to 2.
As the spiral continues around the cipher clock each character is given another value
that can be used in your cipher. A is also equal to the number 30, in the second
spiral. Can you figure out what the value for A is on the third spiral? Look for
the answer below the picture.
Answer: Letter A is equal to values 1, 30, 59, 88, and so on. Simply add 29 to the
original value of A to get the value for the next spiral. You add 29 because there
are 29 characters in the entire cipher clock. Using the spiral you can write a cipher
using any of the values for each character on the spiral cipher clock. Using the
spiral above see if you can decipher the message: 21,14,4,58,18,19,20,30,14,33.
Answer is "understand." Notice how "d" is represented with two different values?
Make your spiral cipher clocks even harder by using non-sequenced letters and extra
characters.
