Quiz machine is a term used in the UK for commercial coin-operated video quiz games that offer cash prizes for winning performances. These machines are usually found sited in pubs, bars and other places of entertainment. The term quiz machine is often used interchangeably with the trade term SWP (skill with prize) although not all SWP games are quiz based. History The quiz machine first appeared on the scene in the UK in 1985. The first such machine was called Quizmaster which was made by the Cardiff based now defunct Coinmaster Ltd.

In 2000 the quiz machine market reached new highs in player participation with the arrival of the highly popular Who Wants to Be a Millionaire? quiz machine.

These were people who became highly skilled on particular games being able to learn and memorise nearly entire question sets for a particular machine. They could then make substantial incomes from touring many different quiz machine locations and extracting money from the particular types of machine in which they were skilled. Over the years the size of quiz machine question sets has steadily increased, with the extensive use of "spoiler" questions to make large multiple wins difficult or impossible.
