The rules, records and moments the world actually watched.
How often are the modern Summer Olympic Games normally held?
Every sport runs on agreed numbers. These are the ones worth carrying around.
A surprising amount of sport comes down to fixed measurements that almost nobody can recall on demand: how high a basketball hoop sits, how long a football match runs, how far a sprinter actually travels indoors. These numbers are not arbitrary trivia. They are what makes results comparable across countries and decades, and several were fixed for practical reasons that have long since disappeared — a distance that suited one particular stadium, or a height that matched a gymnasium balcony.
Every question in this quiz is listed below with its correct answer and the reasoning behind it. Play first if you would rather not see the answers — or read through as a study sheet.
Play it insteadAnswer: D. 3.05 metres, or ten feet
Why: The height was set by the balcony rail Naismith nailed his baskets to, and has never changed.
Answer: C. 90 minutes
Why: Two halves of 45 minutes. Added time compensates for stoppages and is at the referee's discretion.
Answer: B. 50 metres
Why: Short-course competition uses 25 metres, and times in the two are recorded separately because turns give an advantage.
Answer: A. 18
Why: The number came from St Andrews, which reduced its course to eighteen in 1764 and became the model for others.
Answer: D. About 6 centimetres
Why: Three feet at the centre and three feet six inches at the posts, the sag being part of the specification rather than slackness.
Answer: C. Seven
Why: Each position is restricted to particular thirds of the court, which is the main structural difference from basketball.
Answer: B. 400 metres
Why: Outer lanes are staggered at the start so every athlete covers the same distance.
Answer: A. Ten
Why: A perfect game scores 300, which requires twelve consecutive strikes rather than ten because of the bonus balls in the final frame.
Answer: D. 1.73 metres
Why: Five feet eight inches, with the throwing line set at 2.37 metres from the board face.
Answer: C. 64
Why: Eight by eight. The board is oriented so that each player has a light square in their nearest right-hand corner.
