Simon Cowell has revealed that he is making the most expensive gameshow in television history, describing it as the "biggest thing" he's ever done.
The £15million programme for ITV will be called Red or Black and is set to air over a week this autumn.
Every night one contestant could become a millionaire by choosing either red or black on a giant roulette wheel.
Music mogul Cowell said:
"This show is not about talent or skill it is just down to luck. This has never been done before. It is big event TV.
"Every single night for a week viewers will see someone at a giant wheel, risking their luck to win a million. You have to do it - there is no way of opting out.
"It's monstrous the size of this show. It's one of the biggest things I have done."
The first stage of the show is filmed at Wembley Arena and will involve thousands of contestants attempting to predict the outcome of a series of challenges.
Those who guess correctly will move on to the next round. There will be 10 stages in total and each contestant has to predict an outcome with a 50/50 chance of getting it right.
Ant McPartlin and Declan Donnelly, who already work with Simon on Britain's Got Talent and the X Factor, will host the programme.
