How Many Richard Osmans
Quizmaster required: Yes
A quizmaster chooses a famous structure, then contestants need to work out how tall said structure is by guessing how many Richard Osmans. You can only use full Osmans, no halves or quarters. The quizmaster will round up or down to the nearest full Richard Osman. It's best of 5 rounds, and the person with the most points at the end wins.
