Imagine if you're playing a game where you have to answer a bunch of questions in order to win. Now, there's a rule in this game called "multiple jeopardy". This means that if you get one question wrong, you have to answer two more questions instead of just one to keep playing. But, if you get those two questions wrong, you'll have to answer four questions to keep playing. And if you get four questions wrong, you'll have to answer eight questions, and so on.
So basically, the more questions you get wrong, the harder the game gets. You have to keep answering more and more questions until you finally get one right. This rule makes the game more challenging and makes it harder to win.
