He first appeared on Countdown on 18 January 1994, beating Gill Nickson 57 – 44 in the 12th heat of Series 27. He won three more games before losing 51 – 45 to Robin Benoy, but his four wins were enough to see him return for the finals as No. 3 seed. There, he beat Alan Ward and Daniel Simonis on his way to the final against octochamp and hot favourite Richard Campbell. The final was a close affair, but Elias eventually sealed victory on the final, very difficult numbers round to win by a score of 68 – 55, and thus became the 27th champion of Countdown.
In other occupations, he wrote questions for many quizzes such as The Weakest Link, The Krypton Factor, University Challenge, Busman's Holiday, Wipeout and Who Wants To Be A Millionaire?.
He sadly passed away on 17th December 2005.
