The radio replacement for Sporting Chance was a general knowledge quiz, in which the panel toured seaside resorts, trying to beat the local brainboxes. The top three teams in about ten heats came back in the semi-finals, and the two highest aggregate scores met, town to town, in the final.
Treble Chance Overseas (sometimes remembered as Forces Chance) was the same format, but travelled internationally to pit the resident panel against members of the armed forces.
After 1966, the seaside theme was dropped and the series toured universities instead. Towns versus the panel returned for the 1970-71 series, which aired to Radio 4. The show didn't fit the Home Service's highbrow ethos, and returned to Radio 2 for the 1972 series, pitting BBC local radio stations against each other. The panel had now retired, and Treble Chance became a town-versus-town show from 1973. By 1978, it celebrated the UK by inviting four teams from each of England, Scotland, Wales, and Northern Ireland.
The title referred to the fact that there were three styles of question: ordinary Q&A, true or false, and spelling.

There were occasional challenge matches between the Treble Chance panel and the finalists of What Do You Know? (latterly Brain of Britain. These followed the series on 11 July 1973, 17 July 1966, and 8 July 1969, all chaired by Franklin Engelmann.
Two other specials were produced: a live edition on 17 March 1965 from the Ideal Home Exhibition, and Treble Chance in Europe on 13 June 1973, marking the UK's accession to the EEC. The entire 1974 series featured British towns and their continental twins.
A Treble Chance Quiz Book was published.
