Simon Cowell's new show could make seven millionaires in a week - in a game of chance live on television.
Simon has joined up with Ant and Dec for the show, called Red or Black, which will be on ITV1 for seven nights later this year.
Thousands of contestants will have to choose red or black in a series of competitions which will reduce their numbers until only one person is left before they will play a final game with £1 million at stake.
Dec, who will co-host the show with Ant, said: "What's very exciting about it is they will either go home with a million pounds or they will go with nothing.
"It's all about luck, there's no skill or talent involved. You don't have to come and do a song or have a snake wrapped round your neck.
"You don't have to do any of that stuff, you just have to come on and if your luck holds out for 10 times in a row, if you are that lucky, you are walking away with a million pounds."
The X Factor supremo admitted the show was a risk and said programme makers would have to take out insurance in case seven people won and they faced a £7 million payout, but insisted it would be a success.
He said: "I'd love to take it around the world. I think the concept works, but it's a very expensive show to make. You can't do it small."
