Okay, so the smart bets for online craps are Pass/Don't Pass (and Come/Don't Come). Now how can we improve the best bets at the Craps table? The Odds, that's how -- either by Buying Odds when you play "right" (Pass) or Laying Odds when you play "wrong" (Don't Pass). These are placed in addition to your initial bet after the Come Out roll and the reason they improve your initial bet is that the house takes no edge on Odds. That's right, zero house. All you're betting against is the straight dice. But you could spend a long time looking at the craps table felt trying to find where the Odds bets are supposed to go. The truth is they're not marked. It's a "hidden" bet, so to speak.

The word is that in Las Vegas the big houses simply take the position that it's not their responsibility to inform the players of all their betting options, so the Odds stay unmarked. Needless to say, our online casino friends are not in the business of correcting Vegas so they take the same approach: no Odds to be seen. No biggie, it's an easy bet to make and it will improve your original Line bet by almost halving the house edge or better, if the house let's you do it.
