The Drop ran every half-hour from 5 to 12 October 2015, and returned in the same format from 3–10 October 2016 and 2–9 October 2017, at 0 and 30 minutes past the hour. Mod Kelvin could be spoken to start the quiz in 2015; Count Check filled the role in 2016 & 2017. Questions were timed and always in the same order, with one point awarded for each round that is completed. Getting a question wrong or failing to answer in time eliminated the player from the quiz. Winners could leave via the exit sphere.
