round, but have still beaten five Eggheads. Occasionally, one remaining Egghead will beat five challengers. Only once have the Eggheads lost four games in succession and only four times has a team of all five challengers won the final round. Since 2021, it has been four Eggheads against four challengers, instead of the previous five. Rounds The show is played in five rounds. The first four 'one-on-one' 'elimination' rounds each focus on one subject category (of nine) while the final 'conferring' round tests general knowledge. In the first four rounds, the challengers choose a member of their own team to play, and an Egghead against whom they wish to compete. The players for that round then leave the studio to go into the "Question Room". The challenger is given the choice of going first or second. Both players are asked in turn three multiple-choice questions. If there is no winner, the round goes into sudden death with no choices given for answers. Since the show moved to Channel 5, there have only been four players per team, and thus only three 'one-on-one' rounds. The player who wins each round earns a place in the final round, while losing players are eliminated from the game. The final general knowledge round is then played between non-eliminated Eggheads and challengers with a similar question format to the previous rounds, with the exception that if more than one remains on a team they may confer. If the challengers win they take the prize money; if the Eggheads win, the prize money is increased by £1,000 for the next quiz. Subjects There are nine (formerly eight) possible subjects for the first rounds. They are: Arts & Books (2003–present) Entertainment (2003–2008) Film & Television (2008–present) Food & Drink (2003–present) Geography (2003–present) History (2003–present) Music (2008–present) Politics (2003–present) Science (2003–present) Sport (2003–present) Music and Film & Television were introduced in Autumn 2008 through a split of the Entertainment category. Subjects can appear in any order, although at least one of Sport, Music or Film & Television will appear in every episode. Despite the splitting of the Entertainment category, Music and Film & Television can appear in the same episode, sometimes consecutively. "Eggheads" In the first eight series, the team consisted of only five Eggheads who each appeared in every episode and did not rotate. At the end of 2008, a sixth Egghead was added and appearances rotated.
