In Australia, they've revamped it and call the show 'Million Dollar Hotseat',

They have a rotation of contestants, and if you don't know an answer you can pass... every time someone gets one wrong, they are eliminated and the top prize goes down by one level

Every night someone is answering a question for prize money, sometimes it's $5,000 sometimes over $100,000 sometimes that's the only question that person has to answer all night.
