Once in college we ran an online treasure hunt where the participant needs to decode from images, text hidden in source code.

Decoding using enigma was our last question. The word "That's all folks" was encoded in five different ways & configuration for enigma machine would keep changing according to the time of the day. We took reference from computerphile videos & people really loved solving this.

We redirected them to an online enigma decoder (Forgot the link)

Good old times :-)
