Getting ready for my next trip to Beau Rivage, and was checking out the IP website.

They have the following "Bonus Craps" bets listed (20x Odds).

ALL SMALL OR ALL TALL
All the Small (2, 3, 4, 5, 6) numbers or all the Tall (8, 9, 10, 11, 12)
numbers will be rolled before a 7.

ALL OR NOTHING AT ALL
All the numbers BUT seven will be rolled before a 7.
Pays 175-to-1.

PETE & REPEAT
Any random number will be rolled twice before a 7.
Pays Even Money.

TWICE IS NICE
Any random “hardway”... 2 (1-1), 4 (2-2), 6 (3-3), 8 (4-4), 10 (5-5) or 12
(6-6)... will be rolled twice before a 7. Pays 6-to-1.

DIFFERENT DOUBLES
At least three different doubles will be rolled before a 7.
Three Different Doubes pays 4-to-1
Four Different Doubles pays 8-to-1
Five Different Doubles pays 15-to-1
Six Different Doubes pays 100-to-1


I think I have learned enough from the folks here to calculate some of the more obvious bets, but some of these are beyond my ability. Out of all of them, the Pete and Repeat is the most interesting I think. If I understand it right, if ANY 2 numbers are rolled twice, before a 7 shows up, I win even money. I wonder when you make the bet? Do you have to make it on the comeout roll, and of course, you lose on the comeout 7?
I think it would be interesting just to see how they keep track of this bet.

It doesn't matter when you make the bet, provided that there is no special treatment of any type of craps roll for the purposes of the bet. The dice do not know whether you're on a come out roll, trying to make a point, or playing Yahtzee. If you treat every roll at the table as its literal value for purposes of these bets, the odds are just the same as if you roll some dice at home for the sole purpose of resolving such a bet. If they limit when you can place the bet, I imagine that has more to do with the difficulty of keeping track of such bets than anything else.

I assume that the hardway bets are the ones you can calculate yourself, but I'll share my answers for reference.

DIFFERENT DOUBLES
The house edge is 27.9%, as shown.
Different doublesPaysExactProbabilityReturn
0-11/20.5-0.5
1-13/110.27272727-0.27272727

61001/9240.001082250.10822511
Total11-0.27922078


TWICE IS NICE
The probability of winning is 0.10086323, or 4183/41472 exactly, for a house edge of 29.4% when it pays 6-to-1.


The first three bets would be inconvenient to analyze without some type of programmable computer. They would require considering at least 3^5 = 243 possible states, although with a computer it is most convenient to analyze 2^10 possible states (treating the numbers in each of the five pairs that have the same probability separately rather than together). It is a nice exercise in dynamic programming.

ALL SMALL OR ALL TALL
The probability of winning is 0.04745011, or 8586422437/180956833200 exactly. The house edge depends on the payout.

ALL OR NOTHING AT ALL
The probability of winning is 0.00525770, or 126538525259/24067258815600 exactly, for a house edge of 7.46% when it pays 175-to-1.

PETE & REPEAT
The probability of winning is 0.47106649, or 1730378051/3673320192 exactly, for a house edge of 5.79% when it pays even money.


It is also highly worth looking at the Wizard's craps side bets page, which lists the All or Nothing at All bet as the All bet offered at Sam's Town (note that that bet pays 175-for-1, or 174-to-1, rather than 175-to-1, which could just be an error on some casino's web page, but this has no bearing on the probability of winning, only the return).

His page also lists the Small bet and the Tall bet, and together with the All bet we can calculate the All Small or All Tall bet from the Wizard's numbers. Let S, T, and A be the events of winning these bets.
P(S or T) = P(S) + P(T) - P(S and T)
However, winning both the Small and Tall bets (both placed at the same time) has the same probability as winning the All bet, so:
P(S or T) = P(S) + P(T) - P(A) = 2 * 0.026354 - 0.005258 = 0.04745

As for the Pete and Repeat bet, you'll just have to trust that I know what I'm doing. I'm willing to explain further, but I fear it is of limited interest except to computer programmers.

I think the all or nothing is a fun bet. The way I figure it, an 8% house advantage is not a big price to pay for that kind of return on a dollar bet.

Sometimes I cover the hardways at $5 apiece because when I win three times before the 7-out it's a thrill. I figure you could get the same kind of thrill by throwing $1 at this long bet, at a lower house edge than hardways.

Pete and Repeat doesn't seem like that much fun, as there are a lot of ways to get even money or nearly even money bets on the craps table. Why pay a premium house edge for such a low return. Just put more money on your odds.

Generally, I think it is OK to pay a higher house edge to get more of a thrill out of a big return. But in general just remember No side bet was ever invented to help the player!.

Thank you ZPP for your analysis and HA. I knew I had seen some of these bets listed before, but I could not find them. How I missed them on WOO is beyond me. I did go look there, but obviously not very well. Of course, my wife will not be surprised by this....

MS has pretty favorable craps rules, so I am sure it is most likely 175 to 1.

Yeah, giving up 5.7% for an even money bet is not very interesting. As you noted, there are lots of other ways to achieve even money and not give up that much HA.

Yeah paco, I agree that the All bets could be interesting to throw a few bucks at it. I rarely play the hardways, so I may throw those few bets towards this bet and see what happens. You are right, hitting that bet would be fun times.

It seems like the rule is no side bet can be created unless it produces a double digit HA.

This is another bet I just heard of so I had to calculate it.

I'm not a programmer so I used Excel. It's a matter of listing all possible combinations (1,024) that you can roll without a resolution, and then win. From there it's just multiplying out and summing all the possibilities. This is similar to the way I calculated the Fire Bet, though for that one the order of points made does matter for calculation purposes.

One question I have is how you came up with the fraction of 1730378051/3673320192.

My number in Excel is 0.471066490410645, which shows no sign of repeating at max digits allowed.

I had all small/tall/all, and was short a 3 for the small and 8, 12 for tall. I wish it was crapless craps or I would have layed them to lock in a win.

You forgot the word 'financially.'

Every side bet, and game for that matter, is designed to seperate a player from his bankroll.

The successful ones do it by helping the player enjoy the process.

The Pete and Repeat bet can also be calculated by integrating the function:

((x/36+1) * (x/18+1) * (x/12+1) * (x/9+1) * (5x/36+1))^2 / (6 * e^x)

Then taking the complement gives 1730378051/3673320192 or about 0.471
