Napkin Numbers

Napkin Numbers is a daily puzzle for anyone who's ever worked out the math on the back of a napkin — no trivia, no lookups, just your own reasoning against a real-world number. Every day brings two questions: • An Everyday question — something intuitive, grounded in daily life • An Unfamiliar question — something a little further from what you'd normally guess at There's no "right" way to solve it. Use whatever gets you close: reasonable assumptions, rough multiplication, a gut check. Lock in your answer and see exactly how close you landed, scored as a multiplier where 1x is a perfect guess and anything else shows exactly how far off you were. Then comes the reveal — the real answer, broken down step by step, showing the actual napkin math behind it. Nothing in Napkin Numbers is just a cited statistic. Every answer is a genuine, traceable derivation you could work out yourself.…
