Craps- Don't Pass and Don't Pass Plus Laying The Odds

-Don't Pass-

A bettor on "don't come" is referred tp as a wrong or back-line bettor. The house pays 1-to-1 when the shooter bets on don't pass. The terms are opposite of the "pass" bet. The only exception is that the house will not pay for all three of the come-out craps. They usually consider 2 or 12 as a stand-off or a tie. If the legend states that the 2 is barred and it is rolled on the come-out, the bettor is unaffected. The chips remain in place until a decision is met on a subsequent roll. Some places bar the three, which increases the house vig.
The house edge on Don't Pass is 1.4 percent, virtually identical to the bet on Pass. The house vig becomes 4.39 percent in places where they bar the 3. If this is the case, Don't Pass is to be avoided.
The bet is only accepted before the come-out roll, and can be withdrawn anytime afterwards. Naturally, it is a mistake to withdraw after the come-out, when the shooter is trying to roll a point and the probabilities greatly favour Don't Pass.
The chips go on the "don't pass" area, which should contain a picture of two die adding up to either 2 or 12 with the word "BAR" next to them.

 

-Don't Pass Plus Laying The Odds-

After the shooter has established a point, some online casinos allow Don't Pass bettors to bet that the shooter will crap-out before repeating on the point. The don't pass bettor must give them:

Point	Odds
4 or 10	2-1
5 or 9	3-2
6 or 8	6-5

Some casinos require a Don't Pass bet of $30 (or a multiple). Some places allow larger bets on Free Odds than on Don't Pass, but only large enough to produce winnings equal to the Don't Pass bet. Some permit the bettor to double the Don't Pass bet, but it can involve betting as much as $90, although it reduces the house vig to only .459 percent. When the bettor is only allowed to bet single odds, the house percentage is between .69 and .83 percent, depending on the online casino.
