Don't Pass / Don't Come Free Odds Bet
This is the best bet in the casino and my personal favorite. The don't pass/come bet is used in conjunction with the don't pass line bet or don't come bar bet. Basically when you wager on the don't pass or come line, you can use this free odds bet after a point has been established in order to get paid true odds. I will explain the specifics of this bet below. This odds bet is the same for both the don't pass and don't come wagers.
First of all, when you wager on the don't pass or don't come line, you are betting that the dice will land on a 2, 3, or 12 to win. You will lose if a 7 or 11 is rolled. The important thing to notice is that the number 7 comes up more frequently than any other number. In order to activate the odds bet, you need the shooter to roll one of the point numbers (4, 5, 6, 8, 9, 10). Remember that the odds of rolling any point number is better than the odds combined of rolling a 7 or 11.
Once the point is established, a player may make bets in multiples of your original line bet such as 1x, 2x, or 3x. Note that in big casinos like Atlantic City and Vegas, players have the opportunities to wager 10x, 50x and even 100 times the original bet on the odds bet. The free odds bet pays out true odds. Yes, that actually means the house has no edge (0% edge). Though they still have an edge on your original line bet. The rule to remember is that the more money you wager in odds bet, the lower the house edge gets overall on your total bet.
The don't pass line has a 1.36% house edge. Adding on a don't pass odds bet will decrease that percentage even further. Note that you win both your don't pass odds bet and don't pass bet (or don't come odds bet and don't come bet) when the dealer rolls a 7 before the point number, which is more likely than the point number and benefits you even more. The numbers 6 and 8 pay out 6:5 odds, 5 and 9 pays out 3:2 odds, 4 and 10 pays out 2:1 odds or $2 for every $1 wagered.
I added a picture to make things a little clearer and I will explain it below. First I made a don't pass line bet and the shooter rolled a 10, which became the point number (indicated by the "ON" disc located on 10). The dealer then moved my chips to the "don't pass" area of the 10 section in the craps layout. I was then able to use the don't pass free odds in multiples of 1x, so I made an addition odds bet equal to my original bet, so there are two stacks of chips both worth $88 each. If the dealer rolls a 7 before a 10, I will win both bets. Recall that I will be paid 1:1 on the original don't pass line bet, plus 2:1 on my odds bet.
The don't pass line bet used with maximum don't pass odds bet is the absolute best bet you can make in craps or anywhere else in the casino! This has slightly better odds than even the regular pass line bet used with pass odds, so it gives you the best mathematical odds possible. In fact, the casino doesn't actually display the odds bet on the craps table layout and that's why it is sometimes known as the "secret craps bet".
