I have been occasionally watching the Talpa show "Een Tegen 100" which is also run by the Postcode Loterij which runs Miljoenenjacht (the Dutch DoND). I don't speak Dutch, but I like trying to figure out the questions.
The format:
One player sits in a chair facing 100 opponents. The solo player is given a category and occassionally a video clip and is asked whether if he/she wants an easy or hard question. The question and 3 choices are then given and the 100 players are given 5 seconds to enter their answer. The solo player then must answer. If the solo player is correct, then he/she is given money based on the percentage of opponents who got it wrong (50000 euros * percentage). Those opponents are out of the game and the solo player gets to continue vs. the remaining opponents. If the solo player gets it wrong, his/her game is over, and a new solo player is selected from the remaining opponents. However, if the solo player has any money, the player can skip a question they don't know, but at the cost of an increasing percentage of their money (25 - 50 - 75%) and receives no money for opponents eliminated by that question. If the solo player can eliminate all the opponents, the player keeps all of the money he/she has accumulated.
I was wondering if this format would have a chance in the US.
