Conor Travers triumphed in Friday’s grand final of the Channel 4 show’s special 30th birthday series, which has been broadcast over the past two months.
The 21-year-old beat Jack Hurst with a score of 146 – equalling the highest ever points total in the show’s history.
His march to victory included three successive nine-word rounds – ‘ponytails’, ‘detainers’ and ‘normalize’. And he unravelled the day’s conundrum – leviathan – in approximately one second flat.
Conor made history in 2006 when, at the age of 14 and a pupil at Cardinal Newman High School, he became the programme’s youngest ever series winner.
After passing his GCSEs he moved on to Luton Sixth Form College where he studied for A Levels in maths, further maths, physics and computing.
He now reads mathematics at St John’s College, Cambridge.
At the climax of Friday’s finale as the speed of Conor’s solving of the conundrum drew admiration from the audience, show host Nick Hewer said: “That deserved wolf whistles – 146, you did it! Excellent stuff.”
Conor was presented with his winner’s trophy by Marcel Stellman, the Belgian record executive who brought the format of a French game show – Des chiffres et des lettres – to Britain, where it became Countdown, in 1982.
