What makes trivia actually fun vs. just a list of questions
Trivia nights live or die on question quality. Questions that are too easy are boring. Questions that are too obscure make people feel stupid. The sweet spot is questions where the wrong answers are plausible — where you can see why someone would pick B — and the right answer produces a satisfying moment of either 'I knew it!' or 'oh, that makes sense now.' The bonus fact instruction adds the layer that actually makes trivia social: the thing you didn't know that you immediately want to tell someone.
Customizing for your audience
The topic field is where you make this yours. A group of coworkers might enjoy a round on company history or industry trivia. A family game night might mix 90s pop culture with easy geography. A group of friends who all love a specific TV show gets a themed round that turns into a competition about who's the real fan. Name your specific topic and the questions will be calibrated to people who actually know that subject — not generic questions anyone could answer.
