The name of it would be Mystery Digit. It would be played for a three digit prize, two four digit prizes and a car, behind a door. The game would be positioned like Master Key, starting at the turntable and moving to center stage.
Each time the game would be played, the overall theme would be a digit, in the following example it will be 5. On the turntable, there would be five SP''s all missing one digit. The contestant would have to decide if the missing digit is the mystery digit, once again in this case 5. For every one correct, they would get a ticket.
After this part is completed, we move to the main board in the center of the stage. In each of the four prizes trying to be won, each one has the mystery digit in its price once. The contestant must choose which one it is. For every mistake made, it cost them a ticket. The game is over when they win the car or they make a mistake with no tickets left, in which they leave with what they have. I hope my example make it clearer
