I explained the basics of frequency analysis and let em go.
Not only did they solve the clue within a half hour (and claim their prize), they presented me with their own encoded clues for a treasure hunt of their own design! Wow, that was harder than I expected, expecially since the messages were almost too short for any sort of meaningful frequency analysis.
See how well you can do.
The first one was a stumper – and it contained an error which added to the fun:
And this one was pretty tricky too:
Today you stumble upon a secret code that could lead to treasure
To whoever finds this,
26,21,24,- 25,18,6,6,- 3,18,7,2-20,16- 14,10- 10,4,16- 23,10,14,17,16- 9,21,15,19,18,7,17-21,24,10
