How many people have won the AM Show's Nine in 10?
The beauty of the AM Show's Nine in 10 challenge is its simplicity.
Contestants are given a category - elements of the periodic table, for example - and have 10 seconds to name nine things that fit it.
Nine in 10 is a regular fixture on MediaWorks' The AM Show, where it's played three times a week.
The show sends a cub reporter out into a public place somewhere in the country, and they have to corral somebody into participating.

The game was created by Paul Henry, who introduced it in January 2014 on The Paul Henry Show which aired late-night on Three.
In 2015 Henry switched to mornings with Paul Henry, and took Nine in 10 with him. When he left the show at the end of last year, the game stuck around as a feature of his successor Duncan Garner's show.
Since it began, more than 30 people have won Nine in 10. Some of the winning topics have included board games, zodiac signs, countries in Europe, world currencies, states in the USA, high school subjects and elements on the periodic table.
The game needs to be difficult to win because there are serious prizes available. Winners have won trips overseas and shopping sprees. In terms of dollar value, the most expensive prizes have been cars valued at over $30,000.
The show has given away seven cars in its history. Not bad for 10 seconds work.
