The person who organised the quiz finally gets to play in it.

Somebody always has to be the quizmaster, and that person spends the evening reading questions out and marking answer sheets while everybody else has a good time. Usually it is whoever booked the venue.

Here the game does it. Questions, rounds, timing and scoring all run on their own, and you sit down with a team like everyone else.

Or run it from a laptop, if you would rather

Two ways to do it. Drive the whole thing from a computer at the side of the room, or use your phone as the remote and stay in the game while you do it. Same quiz either way.

A proper quiz night, not a buzzer race

Thoughtful questions, teams at tables, time to argue about the answer before you commit to it. It is the British pub quiz pace rather than the fastest-finger-first kind, which is the difference between a round that fills an evening and one that fills four minutes.

Sixty to ninety minutes

This is the long one. Most of the library runs five to twenty minutes and fits into a gap. This is the evening itself, with rounds, a break in the middle if you want one, and a result at the end that people care about.

Where it works

Pub quiz nights. Company socials and Christmas parties, particularly the ones where the organiser would quite like to enjoy their own event. Clubs, societies and community groups that run a regular quiz and have run out of volunteers.

What it is not

A filler. It takes an evening, and the whole design assumes you want it to.

It is also not a game you can half-watch. It rewards a room that is sitting down and paying attention, which is what a quiz night is and what a drinks reception is not.
