The Die Roller is a great option for Let em Roll. Start out with 5 dice, assign $500 to the one spot, $1,000 to the two spot, $1,500 to the three spot, and cars to the four, five and six spots. Assuming the contestant has at least two rolls, eliminate all cars in subsequent rolls; for example, if two cars are rolled, use three dice for the next roll.
