Travers was originally planned to make his début in the first episode of Series 54, but due to illness his appearance was pushed back by several weeks and he instead began his run on 23 November 2005 against Ray Oakley. He won his first game with a score of 99, followed by 111 against John Archer and 99 against Geoff Alderman. His remaining 5 games were all centuries, with a top score of 124 and a low score of 111. During his run he beat Series 73 finalist Judy Bursford. His octochamp total was 890.
He beat Daniel Peake by 69 points in the quarter-final, Paul Howe by 24 points in the semi-final before meeting Matthew Shore in the series final. There he won narrowly 98 – 83 to become the youngest ever series champion, at 14 years old. He also holds the record for winning the longest series, as the series started the previous year due to the death of Richard Whiteley, which delayed the start of the series being filmed. In total, 153 episodes were filmed, the most ever for one series. Travers was the first to be crowned with Des Lynam as a presenter.
One week later, he returned for CofC XII beating John Hunt and John Brackstone in the first two rounds. Considered one of the favourites after his 890 aggregate as an octochamp (the sixth highest ever), he lost 118 – 102 to the eventual winner Paul Gallen in the semi-final (on a crucial conundrum). In 14 games, Travers' lowest score was 98 and his average was 110.4 points per game.
Since losing to Paul Gallen, he appeared on Countdown's 25th anniversary special against Chris Wills and won the game 69 – 58. He then started playing Countdown online again and spent some time in the #1 position on Apterous, and until recently had the highest ever score of 161.
He returned to Countdown in 2013, as one of 41 contestants taking part in the 30th Birthday Championship. He won his first match against Series 46 champion Ben Wilson, then beat Series 52 champion Mark Tournoff, just missing one maximum in the whole game. His next match saw him go one better, as he scored a perfect 119 against Series 28 quarter-finalist Chris Hawkins. He then defeated the Series 60 champion Kirk Bevins in the quarter-final, again scoring a perfect 119 points. He then took on the Series 53 semi-finalist Jon O'Neill in the semi-final, being held in place for all the game, before eventually breaking clear by solving the conundrum INFIGHTER to achieve a 3rd consecutive perfect game, this time with 120 points.
The grand final of the championships took place on 1 March, when Travers played the Series 63 champion Jack Hurst. Travers took an early lead in round 3, when he spotted the niner PONYTAILS, and the only points he dropped from thereon were the 3 for not reaching the target in the first numbers game. Hurst's challenge ended when he missed POMADES in round 13, leaving Travers to max the final 2 rounds to equal the highest ever score in the show's history with 146, a feat achieved by Julian Fell over 10 years earlier in the Series 48 semi-final.
Travers has the record for highest total score in the normal series, having scored 2,279 cumulative points in 20 appearances. However, Jon Richardson claims to have broken this record over several series of 8 Out of 10 Cats Does Countdown, following a game where he scored 890 due to a conundrum worth 834 points.
