The National Lottery: Secret Fortune is a BBC National Lottery game show that was broadcast on BBC One from 12 February 2011 to 29 December 2012.
Nick Knowles hosts the high-tension quiz show in which a pair of contestants must find the highest sum of money contained in one of 24 numbered envelopes, each containing a randomly assigned sum of money between £100 and £100,000. This is done by correctly answering a series of multiple choice questions.
