Every level has an 18-question bank. New random rounds use a fresh, unseen combination until the current set cycle has appeared, then start a new cycle. Question order and answer order are also shuffled. A relevant credited photograph appears when the archive has one; every checked answer includes d.s field-note links and an external reference opening in a new tab. Likes, best scores, and rankings stay on this device; challenge links reproduce the exact round.
