How it works
Ten questions, one go, a fresh set every midnight UTC. Today's quiz draws on history, geography, science, sport, food and the odd surprise from a bank of more than 1,400 checked general knowledge questions, so no two days look alike.
Everyone in the world gets the same ten, in the same order, which makes the result worth comparing. Answer quickly for more points, keep a streak going for a bonus, and watch the last question: it counts double.
