Treasure Hunt Ideas

Encryption

Treasure hunters are given an encrypted clue that leads them to their next clue.

A simple encryption is to replace each letter with the next letter of the alphabet (a becomes b, b becomes c and so on to z becomes a). This is a good encryption provided the hunters recognise what has been done. Alternatively a key could be given that maps out which letters have been swapped. The hunters could be given something like this (maybe with a previous clue?) to use to decrypt the clue:

A B C D E F G H I J K L M N O P Q R S V U V W X Y Z
X C V I S P B D H A W L R O Q F K T N Y J Z E U M G
