A 2 or 12 will be rolled on an average, once in every 36 rolls, true payoff would be 36 to 1. You will notice, however, that casinos only pay off on such bets at 29 to 1, (30 for 1). These variances provide the House with an overall 16.6% edge over the players on such bets. This disadvantage for the player is offset by players who are smart enough to take odds on their Pass Line and Come bets.
