Buying other people's odds on craps Spero, actually you do not lose 50% of the time you lose 50% of the amounts you would wager. You would also win 50% of the amounts you wager. Because of the odds offered on the bet you would lose more often than win but you would receive additional amounts (odds) from your winning wagers. In craps that would be for a 6 or 8 - 6 to 5, for a 5 or 9 - 3 to 2 and for a 4 or 10 - 2 to 1. It is the best bet in the casino but as such is a washout from a betting standpoint. Over a statistically valid period of time (number of rolls) you should come out with the same amount of money as you started with. At least that is the way I understand it. Could be wrong but don't believe so.
