Rounds
Each episode has three rounds.
 * Fact Off - The three guests reveal their favourite fact and try to see if it is true. The fact proving segments are narrated by John Sergeant.
 * Fact Finder - Each of the three guests choose an audience member who has a fact which is given to three experts who reveal if the facts are true or not.
 * Chemical engineer David Wharton
 * Cell biology and genetics Dr Emily Grossman
 * Rocket scientist Dr Simon Foster
 * Space scientist Dr Maggie Aderin-Pocock
 * Mack's Fact - The guest with the highest score takes part in a fact Mack wants to prove.

Thirty-minute edits of (at least) Series 1 exist, in which the Fact Finder round is absent, and no points appear to be awarded throughout.

Episodes
46 episodes were produced, with the final episode of each series (the eighth episode) being a best-of compilation. The final episode for series 6 (a best-of compilation) was unaired.

Reception
Writing for The Arts Desk, Matthew Wright said of the first episode "With QI's questions about Noam Chomsky substituted for lightweight popular psychology and an investigation into dog urine, there's not enough substance to bear the weight of the lengthy investigations."
