Quiz night themes.

A theme sells the night on the poster and gives the room something to talk about. Fifteen that work, and how to build one.

Fifteen themes

A decade. The 80s, the 90s, the 2000s: music, film, news and toys from ten years. Dress-up optional.
Film night. One round per genre, a picture round of stills, and a closest-wins round on box office.
Music night. Intros, lyrics, covers and the year it charted, across the decades.
Sport. Famous moments rather than statistics, and more than one code.
Local. The town, the suburb and the venue. Written by someone who lives there.
Around the world. One country per round: its food, its landmarks, its words.
Christmas. Films, songs and traditions, and the year in review.
Halloween. Horror films, monsters, superstitions and a spooky picture round.
Television. Theme tunes, catchphrases and characters across the decades.
Food and drink. Cuisines, cocktails, ingredients and brands. Pairs with a tasting if the kitchen is in.
Science and space. Animals, the human body, the planets and inventions.
Books. First lines, authors and the films they became.
The last few years. Recent news, sport and culture. Levels the room by age.
Brands and logos. Slogans, mascots and logos with the name taken off.
A bit of everything. One round from six themes. The safest way to please a mixed room.

One theme, many angles. A decades night still wants a picture round, a music round and a closest-wins round.
Keep one round general. Not everyone came for the theme.
Name each round. The TV shows each round's title as it starts, so “Round 3: 90s TV” gets a cheer.
