I don't play craps much at all (I'm mostly a slots and blackjack guy), so there is one part about calculating the HA in craps that I don't understand: putting odds behind your pass line bet. As I understand, these bets pay out their actual worth to the player and the amount you can wager there varies between 3 and 20x at most casinos. Isn't the house edge on the game thus diminished based on how much you put on that line? So it's 1.4% if I play the pass and then smaller based on how much I put behind it? Or am I thinking about this incorrectly? Also, can you just buy odds in a game when you're not shooting? And does that mean you can play without a house edge? Seems unlikely, so I'd like some clarification. If they do allow you just make those true value payout bets, I'm guessing they don't include those bets in your rating then. Are there any casinos that do factor in those bets?
