‘Un Cwestiwn’ is the show that turns the quiz format on its head. The first question you see is the crucial one – answer that correctly to win the trophy.

In addition, the more correct answers throughout the show in general, the easier the question will eventually become. Which of the 8 competitors will earn the right to answer the one question? A challenging quiz show, hosted by Iwan Griffiths.
