Often the questions are about trivial or general knowledge topics, so the event may be called a trivia quiz.
When a table-quiz is held in a hotel, pub (ie public house), tavern, etc, then it is often called a pub-quiz.
If a table-quiz is held in the evening, then it may be called a quiz night.
If it is in support of a non-profit cause, then it may be called a charity quiz.
Table quizzes may be purely social events, providing the main entertainment at a gathering. Or they maybe be held to raise funds or to attract people to a venue (eg a pub, church or community-centre) who don't usually go there.
Some people say that
"the pub quiz is a modern example of a pub game." ref: http://en.wikipedia.org/wiki/Pub_quiz
Every quiz is different, but there are many common features:
- People answer questions, often workong together in teams,
- Questions are organised in rounds
- After each round, the questions are marked and the score is calculated
- The teams with the highest score(s) are the winners.
