Did you think it was odd that the winning number is a double zero? We certainly did, and we think it reflects the ultimate hopelessness of the entire situation. (This interpretation would support the idea that the protagonist was screwed to begin with, no matter what action he chose to take.) It is even more ironic that the wheel actually stops on the double zero once the button is wrestled from the protagonist. At that particular moment, you can think about the double zero as representing a double loss: the protagonist and Laura, who are both doomed.
