📏 Range Finder
How many bridges does Hamburg have? Nobody knows exactly – and that's the point. In Range Finder, nobody gives a single number but a range: “between 800 and 3,000”. If the right answer is inside, you score – and the narrower your range, the more points. Too bold and you get nothing. A quick estimation game about knowledge, gut feeling and appetite for risk.

How Range Finder works
- An estimation question appears, e.g. “How tall is Mount Everest?”
- Everyone enters a range on their phone: from … to …
- The stage shows the correct answer and everyone's range as a bar.
- Hits score 1 to 5 points – the narrower, the more. Misses: 0.
Why Range Finder works
- Everyone can play, no expertise needed – caution is a strategy too.
- Playfully shows who likes to go all in.
- The answers are often surprising and spark conversation.

Tips for hosts
- For years, the width counts in years – even a five-year range is bold.
- After the reveal, ask the person with the narrowest range how they knew.
FAQ
How are points calculated?
Only ranges containing the correct answer score. Up to 10% wide (relative to the answer) scores 5 points, up to 25% 4, up to 50% 3, up to 100% 2, and any wider hit 1 point.
