Has it ever been made clear if the losing contestants keep the money they've accumulated? I know it's tradition for daytime quiz show contestants to lose everything, but then it'd make the whole point of winners carrying their winnings to the next show redundant, surely?

Each day's winner banks their winnings, and they win whatever they accumulate. That means anyone who doesn't win a day goes home with nothing, and winners don't get their winnings from their final losing day, and only what they accumulate.
