Alphabetical

The Alphabet Game or Alphabetical is a show broadcast on the BBC.

The game consists on several rounds with different word games. On its final round, the contestants compete to answer separate sets of 26 questions, whose answers each start with a different letter from A to Z in order (with the exception of X, which can appear anywhere in the word). Only one contestant plays at any moment, using the time on their own clock; the opponent's clock is stopped. Both contestants start at A and advance one letter at a time, with the champion playing first. When a contestant either passes or gives an incorrect answer, control goes to the opponent, who resumes play on the letter after the one on which they last passed or missed. A contestant may return to a passed question only by playing through the entire alphabet to reach it again.

During timed rounds, they may pass a question by saying "alphabetical"
