A year ago, I created a secret society for my nephew for his 5th birthday, called the “Puzzle Keepers of Palau”. The society is a long-standing group dedicated to seeking out puzzles and solving them. He recently had another birthday, and I created another puzzle for the occasion.
The idea is that he has to use a set of physical components to solve a substitution cipher, which he can then use to solve a web-based riddle.
While there’s only one copy of the physical clues, anyone with some experience with cryptograms should be able to solve the web-based component without them.
I’ve also put the files for the cryptogram up on github
