 FACT: In the scene where Yen places a bet on the roulette wheel he  covers numbers 11,12 and 13, to fit in with the previous statement  that the fixed ball could be assumed to land on one of three  numbers. 11,12 and 13 do not appear consecutively on a roulette  wheel. If you wanted to cover a bet on 12 for example, youd need  to place chips on 12, 8 and 29 on an American table.
