I am playing a table top role playing game and want my players to discover two words by putting together different hints. Let's assume the words are "devourer" and "avocado".
I was thinking of a simple anagram, such that for the word devourer maybe the players would discover the letters o e v e r u r d over parts of the game and they need to put it together. But that seems a bit boring to me. I believe the level of difficult for anagram is appropriate however, and it is important that the players can figure it out. I'm assuming this is not very difficult, correct?
I was thinking for avocado the players could discover 5A 6D 2V 3O 4C 1A 7O over a long period of time, and that they could put this together to spell out AVOCADO. Again however this seems a bit boring, although maybe more unique than an anagram.
The players will be discovering these hints in a book that can include almost anything a book can include, with the caveat that the book is in their imagination and not an actual book (this is a role playing game). For example I could say to the player that he discovers "A1" in the book or sees a serpent or something, but can't present an actual image.
I should add that I could present an actual cool image to my players if I think it is worth it, but the caveat is that the player needs to discover these words over 12 months and if I can't present the entire puzzle at once.
What would be some fun/unique and relatively easy puzzles for people to put words together?
