Cryptograms are a great source of the "aha!" moment. These 'crypto-lists' increase the fun and the challenge. Rather than just figuring out a pithy quotation, solvers have to decipher an entire list of encoded words, phrases, titles or names that fit a category - like 'Bathtime', 'Greek Gods' or 'Headgear'. Fill in a few letters and a pattern emerges - everything clicks and the message becomes clear. And, just to make things a little harder, sometimes you have to come up with the category too!
