OTOH, not so long ago, a colleague and I tried to guess the number of piano tuners in large cities, e.g. New York. I find your idea nice, but the execution could be more flexible, more puzzle-like. E.g., you could have units (like #passengers, #planes, #flights, time), and the user can create factors out of those.
But I'm afraid that it'll lose its appeal after a while. These problems seem same-y to me, more so than Wordle.
