Guessing Leo in a baby pool
If the parents have kept the name secret, popularity data is a reasonable starting point — most parents pick something in the top few hundred. But guessing one name is a long shot. A pool that allows several guesses per person, and scores near-misses (Leo against a similar-sounding name) rather than only exact matches, makes for a much better game.
