MW’s Codes and Ciphers Series continues to introduce different examples of how codes, ciphers, riddles, and puzzles have been used to hide clues in armchair treasure hunts. This helps both new and old treasure hunters get their creative minds in gear. It may even help you recognize a secret message in the next hunt you work on.
So let’s get to the next example in the series!
The Art of Hidden Messages (appropriately named) used the Polybius Square cipher in the Wizard of Oz hunt. (Section on the MW Forum)
A normal Polybius Square is a 5×5 grid, filled with letters of the alphabet. Most times the I/J are combined in one square as shown below. The rows and columns are then numbered from 1-5.
In this example, with a grid filled as given, the letter A would be represented by 1-1. 1st column, 1st row. An S would be represented by 4-3. 4th row, 3rd column. And so on. Each letter can be represented by a pair of numbers- the row and column it appears in the square.
How this pair of numbers is given can be hidden in numerous ways.
Let’s look at the following image. Do you see a place where pairs of numbers could be ‘hidden’ in plain sight to apply to the Polybius Square for a message?
If you look at the scarecrow’s collar you will notice the frays can be counted. Some clues for this utilizing a Polybius Square is none of the groupings are over 5, and they are of even number (suggesting possible pairing).
If we counted each grouping, paired them up, and then applied it to the Polybius Square, we would get the message:
ON THE PATH
This was one small clue of the puzzle which led a searcher to discovering the solution, and ultimately the treasure!
Best of luck with all that you seek! Always Treasure the Adventure!
