I calculate a 17.95% and 15.79% house edge for triple and double roulette.
I also get 15.79% for double-zero and 17.95% for triple-zero, assuming a win of 3 to 1. Using a colon or dash does not indicate whether the win is "for one" or "to one."
I think the dealer said it was “to one”. If I am correct about gambling laws, paying “three for one” would be breaking the rules of 25% maximum house edge here.
Quote: harrisGreetings glorious Wizard, I did not see a name for this bet anywhere. I will go back to the hotel in a couple hours and ask more about it. If they let me, I can even take a picture of it!

Greetings! Please do. May I use said picture on my site?
See ya tomorrow at G2E!
Quote: harrisI just walked from the Las Vegas airport to the monorail and took it to Sahara’s. When I was there, I saw a weird roulette bet that I had never seen before. Basically on double and triple roulette, the wheels were divided into five sections of eight numbers each (with 1 or 2 shared numbers on triple and double respectively). The sections are named Cheetah, Scorpion, Cobra, Queen, and King. Each pays 3:1

Welcome to Vegas! That awesome jazz song you heard on the Monorail was "El Chromeo" by Britt Warren. It is the official anthem of Alt Vegas, that interstitial city where the chicks give up the kitty, where everything is done a little differently, and you will be expected to be able to recite the lyrics to go overneath the Hidden Underground. Fortunately, there are no lyrics, meaning the password is merely silence.
Just one thing about that game- there are different versions for double zero and triple zero games. There is a selection of either 7 or 8 numbers for each bet, and hitting one of the greens is either a push or a bonus for some of the bets, presumably to keep all the bets close to equal. So you will need to sneak a better peek at the precise rules to get the precise edge.
I wonder if there is a single zero version.
Quote: harrisI did not see any information about pushes and bonuses. The pitboss told me it’s called a Sphinx side bet, which makes me think it’s unique to the Sahara Casino. When they are less busy I’ll ask if I can take photos of both the wheels. I already have a photo of the betting area.

Thank you! I may run across it at the Global Gaming Expo this week. There probably is a single-version on paper, which no casino will ever put in.
The overall game is the same if you just do not play these bets. And from a mathematical standpoint, I would recommend that you do not play these bets.
Also I'm not sure I understand your question. I will hopefully have more information on these bets by the time I leave Vegas.

I welcome all questions, comments and corrections.
However, in double zero roulette, the 0 is a push for Scorpion, Cobra, and Cheetah; they didn’t have a pamphlet for double zero and wouldn’t let me photograph the wheel or table so you’ll just have to believe me.
I wrote it earlier on this thread but stupidly categorized some bets as “inanimate” instead of “animal” (I promise I’m not bad at English haha).
Anyways the house edge on double zero should be 13.1579% ;)
Quote: harrisThe article says “I assume 0 and 00 are the shared numbers” - your assumption is correct.

All 5 are animal.
To further confuse patrons, perhaps some bets can be defined in different ways:
4 of 5 are vertebrates.
3 of 5 are mammals.
2 of 5 are primates.
1 of 5 understands mathematical and logical abstraction, and can safely operate an automobile.
Basically, the theme is up to the casino - for example the Sahara made it Pharoah-themed. I am now more inclined to believe rumors that "this game was at Caesar's a couple years ago"... it seems like it was approved in Nevada in early 2023.
There are lots of options regarding pushing on different 0's.
Additionally, there is also a single zero version.
Let's go!
Okay so first of all there are a few choices for casinos.
Choice 1: Do you want segments of eight numbers each paying 3:1 or segments of seven numbers each paying 4:1
Choice 2: Single, Double, or Triple Roulette
Choice 3: How often should three of the bets push... never, on 0, on 0/00, or on 0/00/000?
Let me start with the 4:1 (seven numbers)
Single Zero
No pushes / non-pushing sections: ((4+1)*7+0)/(36+1) = 35 / 37 = 94.5946%
One push: ((4+1)*7+1)/(36+1) = 36 / 37 = 97.2973%
Double Zero
No pushes / non-pushing sections: ((4+1)*7+0)/(36+2) = 35 / 38 = 92.1053%
One push: ((4+1)*7+1)/(36+2) = 36 / 38 = 94.7368%
Two pushes: ((4+1)*7+2)/(36+2) = 37 / 38 = 97.3684%
Triple Zero
No pushes / non-pushing sections: ((4+1)*7+0)/(36+3) = 35 / 39 = 89.7436%
One push: ((4+1)*7+1)/(36+3) = 36 / 39 = 92.3077%
Two pushes: ((4+1)*7+2)/(36+3) = 37 / 39 = 94.8718%
Three pushes: ((4+1)*7+3)/(36+3) = 38 / 39 = 97.4359%
Now let's go to the with the 3:1 (eight numbers)
Single Zero
No pushes / non-pushing sections: ((3+1)*8+0)/(36+1) = 32 / 37 = 86.4865%
One push: ((3+1)*8+1)/(36+1) = 33 / 37 = 89.1892%
Two pushes: ((3+1)*8+2)/(36+1) = 34 / 37 = 91.8919%
Three pushes: ((3+1)*8+3)/(36+1) = 35 / 37 = 94.5946%
Double Zero
No pushes / non-pushing sections: ((3+1)*8+0)/(36+2) = 32 / 38 = 84.2105%
One push: ((3+1)*8+1)/(36+2) = 33 / 38 = 86.8421%
Two pushes: ((3+1)*8+2)/(36+2) = 34 / 38 = 89.4737%
Three pushes: ((3+1)*8+3)/(36+2) = 35 / 38 = 92.1053%
Triple Zero
No pushes / non-pushing sections: ((3+1)*8+0)/(36+3) = 32 / 39 = 82.0513%
One push: ((3+1)*8+1)/(36+3) = 33 / 39 = 84.6153%
Two pushes: ((3+1)*8+2)/(36+3) = 34 / 39 = 87.1795%
Three pushes: ((3+1)*8+3)/(36+3) = 35 / 39 = 89.7436%
I think it is cool that the inventor made a version with relatively good house edge (2.5641%).
I'm going to sleep a little better tonight, knowing the mystery of the pharaoh has been put to rest 😮💨
