It has been written and presented by puzzle columnist for The Guardian, Chris Maslanka.
During the opening introduction, Chris Maslanka would present a few short puzzles for the listeners and panellists to work on during the course of the programme.
He would then introduce the three panellists, and invite each in turn to present a puzzle to the others.
Occasionally, Maslanka would play the piano, with him and the panellists singing a song, sometimes using some awful (but very well crafted) puns.
Programme five's guest, Stephen Buxton, was a regular Panel Beater contributor, and programme six's guest, Jenny Murray, was a member of the public who regularly answered the Listener's Puzzle correctly.
