Estimania

Five numerical trivia questions are released every day at midnight UTC, drawn from science, geography, history, sport and Fermi-style reasoning problems. Each guess scores 0 to 100 based on its ratio to the true answer on a logarithmic scale, so being ten times off scores zero. Totals out of 500 are ranked on a leaderboard.
