How a round works
A round is ten multiple-choice questions. You have sixty seconds per question. Pick A, B, C, or D, or use your keyboard (1-4 or A-D, then Enter to advance). Every answer reveals a one-sentence fact you can take with you. At the end of a round you see your score, accuracy, best streak, a question-by-question breakdown, and a shareable result you can copy or post.
