7-11 side bet in craps

I was at the Century casino in Central City, CO and they had a side bet that isn't shown here. I didn't write down all the specifics, but the payoff was based on how many 7s and 11s you rolled during your turn with the dice. They counted whether you rolled them during the comeout or when a point was established, so your losing 7 counted towards the total. I know that three 7-11s was a push (so two rolls plus the losing 7) and it maxed out around 10 rolls and paid 100:1.

Has anyone around here done an analysis of this bet? If I need to, I can call the casino see if they will tell me what the payoff schedule is.

Thanks - Bob

Never heard of it. I'd be interested to see the full rules.

Here's the payouts. This is at the Century casino in Central City. Would appreciate anyone's analysis of the house edge. Any seven or eleven rolled while you have the dice counts towards the total, including your final seven that ends your turn, so you have to roll two other sevens or elevens to break even and then it goes up from there. $5 max bet.

7-11 side bet

1 lose
2 lose
3 push
4 3 for 1
5 6
6 10
7 25
8 40
9 50
10 75
11 100

Here is an estimate for the frequency of various numbers of 7/11s. This is only based on 1,000,000 shooters. If you want I can easily run way more sims.

Number of 7s plus 11s	Frequency	Payout	Value
1	498395	-1	-.498395
2	277209	-1	-.277209
3	127625	0	0
4	55264	3	.165792
5	23769	6	.142614
6	10141	10	.101410
7	4380	25	.109500
8	1854	40	.074160
9	740	50	.037000
10	360	75	.027000
>=11	263	100	.026300
Total	1000000		-.091828

tl;dr maybe better than some craps side bets, but overall way worse than standard pass/don't betting

That's awesome, Mike, thanks!

I don't have the layout in front of me, but I think the payout was "for one" instead of "to one", so the real net payout is probably 2, 5, 9, etc, which judging from your chart doubles the house edge to 18%. I've gotten confused about this before, though, so I'll have to look again the next time I'm out.

My post accounts for that. Since I used -1 as the "losing payouts," it should be good for if the payouts are "for one."

Ah, ok, that makes sense. Thanks!
