Our dnd campaign had a variety of riddles, some of them involving an actual chemical experiment, labyrinths and jigsaw puzzles. Here’s two of them; the first one
is a classic find the differences challenge
and the second required to decipher a poem into a series of simple mathematical operations! Had a real blast working on these (also got a small case of
Carpal Tunnel Syndrome
but that’s a story for another time :P) Cheers!
