The programme was created by O'Connor, Rebecca Thornhill, Mark Maxwell-Smith and produced by Objective Productions.
In round three, the teams are given a sentence and asked to finish it, for example "Kevin likes to F".
O'Connor will then ask a question with a three word answer, for example "Who invented the telephone?"

The format in countries outside of the UK is more of a straight-laced game show, following the format of the Italian adaptation Passaparola, and with a famous final round where players have to name an answer to a question for every letter (or the majority of letters) of the alphabet in a time limit, which itself comes from an abandoned Dutch quiz show idea called 21×100.
