American Idol winners) while riding. They would then gain the option to double their money in a final round where they would be asked only one question. If contestants answered their question right, the coaster would launch, but if they didn't, they would be forced off without getting to ride. In addition, contestants would always receive the opportunity to earn extra money by eating some type of meal before the ride, only 2 episodes were found, both feature Xcelerator.
