As a fun and interactive way to unlock the details of a large event during the leadup time, I created an series of onine puzzles that all hung together in sort of escape room style manner. In total it ended up with around 22 different puzzles or riddles, which I am in the process of converting into an online escape room / puzzle hunt that with a story that is hopefully more broadly interesting and not tied to the specific event it was created for.
