Average Time Between Roulette Spins
Thread Rating:
An average dealer may get 27 to 29 revolutions per spin before the ball loses enough momentum and falls to the pockets. An average dealer wont’ help you. A methodical dealer with plenty of spins in their background is likely to spin at an even more regular pace. They may get 28.5 revolutions 90% of the time. That’s what you want to see. In craps 29.6% of total rolls are come out rolls, on average. Spins per Hour in Roulette. When my boyfriend and I first started dating there was this girl that would flirt with him all the time. Well I told him to ignore her or it would be over. He did, or so he said. I was playing roulette last nigh using the 'Martingale' method of doubling down twice after the 1st loss. Dumb, I know, but I usually don't lose much and I gamble a long time. Anyway, what ended the game for me was I was betting even, and in four rolls the number 9 came up in three of the spins. What are the odds of that? Does that sound. Players can bet on whether the ball will fall into the pockets numbered 1–36, but not on a pocket that belongs to the house (that is, the casino). In French (or European) style roulette, the pocket numbered 0 belongs to the house; in American style roulette, the pockets numbered 0 and 00 belong to the house.
If you had just sat down at the roulette table and didn't know that the last 10 spins were black, you wouldn't have a hard time agreeing that the probability of seeing a red on the next spin is 48.6%.

Over the years I've noticed that some people like to pretend that they are 'so called expert roulette players' (cough). For example, people like our own Mr. Jjj. So, I've compiled a different kind of quiz to see just how experienced some of these guys really are.
In order to successfully answer all of the questions, you'll need to have actual casino experience. In order to answer them all, you'll need to be experienced, well traveled, and observant.
Similar questions were posted on the John Patrick messageboard. As you might have guessed, they didn't know the answers.
There are no trick questions and the quiz is just for fun. The questions are for players in the US.

I suppose you could say that, considering that I have invented the side bet Poker For Roulette, it's sad that I don't know any of the answers, except one.14. Is it possible to remove one of the zeros from a double zero roulette game?
According to NJ and PA regulations (and presumably its the same in other jurisdictions), it's acceptable to use a double zero wheel on a single zero table, as long as a sign indicates that a double zero result is a push / no spin.
Personally, I think that means that if the sign is in the double zero space on the table, that you could run a single zero game without changing the wheel OR the felt.
FYI: I needed to find that because part of my idea is to link tables for the progressive jackpot. But linked tables must all have the same type of wheel. My idea is that a double zero would play for my side bet only on a single zero table.

Keyser
Correct! An example is at the Trump Plaza in AC. They simple call it a 'no spin' when the double zero hits. This essentially makes it a single zero game. They have a little felt that they pull out to cover the double zero, showing just a single zero in it's place.

After some people have time to read and answer the quiz I will post the answers.
MathExtremist
I'll give it a whirl, pun intended:> 1. In Las Vegas, which direction do the roulette wheels spin?
> 2. In AC, which direction do the roulette wheels spin?
I've seen both directions as well as alternations. The ball always spins counter to the rotation of the wheel, though.
> 3. In Las Vegas, in most casinos, do you get half of your bet back if one of the green zeros hit when you've placed a bet on the red/black?
No. Only on a single-zero roulette wheel, and only rarely. MGM has a $25 table which offers this rule.
> 4. In AC, on average, do you get half of your bet back if one of the green zeros hit when you've placed a bet on the red/black?
On double-zero games it's allowed, but I can't speak to how common this is.
> 5. When setting at the 'first base' position, on which side is the roulette wheel setting if the wheel is 'LEFT handed'? Meaning, when facing the wheel/dealer, do the players set to the left, or to the right side of the wheel?
> 6. When setting at the first base position, on which side is the roulette wheel setting if the wheel is 'RIGHT handed'? Meaning, when facing the wheel/dealer, do the players set to the left, or to the right side of the wheel?
I'm not a trained dealer, but I assume the handedness of the wheel refers to which hand the dealer uses to release the ball. The dealer always uses the closer hand to release the ball (so as not to turn his back to the table) so a right-handed wheel would be on the right of the dealer (and left of the players).
> 7. At a traditional table, on average, how many spins take place per hour?
45, according to the last floor supervisor I asked. It will depend a LOT on how busy the table is. One player with one or two bets can be 120, while a full table with lots of bets might be 30-40.
> 8. What time of day does the day shift start for most dealers?
> 9. What time of day does the swing shift usually start for most dealers?
> 19. What time of day does the graveyard shift usually start for most dealers?
I've never dealt, but I want to say 10am for day shift, so 8 and 16 hours later for the others.
> 10. On average, how many revolutions does the ball make on a roulette wheel?
It varies; the minimum is 4 in NJ, but it will depend on how fast the croupier releases it. It also depends on whether you measure relative to the wheel or the rotor (since the rotor is spinning contrary to the rotation of the ball).> 11. Who manufactures most of the wheels found in the US?
I'd guess TCS/John Huxley. They do a lot of the readerboards too, especially the newer LCD ones. The only other roulette wheel manufacturers I can think of are Cammegh and GPI, but GPI is more known for chips (Paulson, B&G, etc.).
> 12. Where can the smallest roulette balls be found in use, in Las Vegas, or in AC?
> 13. Where can the smallest roulette wheel in use be found? (Name the state, not the casino)
No idea.
> 14. Is it possible to remove one of the zeros from a double zero roulette game?
It's always possible, and NJ specifically permits it. The traditional order of numbers on a single-zero wheel is different than on a double-zero wheel, but that turns out not to matter mathematically. It only matters for neighbor or French bets (voisins, tiers, orphelins), which don't work at all on a double-zero wheel with a green spot covered up.
> 15. Which direction does a 'left handed' roulette wheel spin?

> 17. Which direction does the ball spin on a 'left handed roulette wheel?
Roulette Spins Data
> 18. Which direction does the ball spin on a 'right handed roulette wheel?
> 20. Do all roulette wheels spin in the same direction?
I've seen both left- and right- handed wheels spun in either direction, and I've seen both styles of ball release (arm out front w/ thumb upwards, and arm to the side w/ thumb downwards). Often the wheel will be set spinning and then the ball released in one steady motion, by swinging the wheel in one direction and flicking the ball backwards when the arm is fully extended. Sometimes the dealer will alternate, sometimes not. I'm not sure if there are any rules on this, so it may just be up to training and house preference. Regardless, the ball always spins counter to the rotation of the wheel.

I thought it is was funny so, on a whim I searched for threads with roulette in the title. I found 95. Most were dealing with questions, but I find it odd that people who posted systems with 'Fool Proof' in the title, or multiple 'Methods' to beat roulette aren't the ones answering. DJTeddybear was the only one with a system that actually answered a question. I'm not really a roulette player but I do find it humorous that I seem to know a little more about the ins and outs of the game than the system/method designers out there.

Hello,
I hope this isn't stuppid question but I need a little more explanation,
When we calculate SD of bets (ie. SD of straight-up bet), this is obviously not the same thing as when we calculate SD of weel frequency related to straight-up outcomes.
For example if one would calculate SD of straight-up then result will be 5,837837..
In the same way if one would calculate SD of straight-up bet according to expected weel frequency the result will be 2,655637.. which is not the same as above.
I know how to calculate both of them, all I need is a little better matematical explanation.
Thank you.

The standard deviation (sigma) is the square root of the variance .
If you have a random variable noted X, then
D^2(X)= M[(X - M(X))^2]= M(X^2) - [M(X)]^2 -> this is the formula for the variance.
The standard deviation is the square root.
M(X) stands for the average.
If you have a random variable noted X, then
D^2(X)= M[(X - M(X))^2]= M(X^2) - [M(X)]^2 -> this is the formula for the variance.

edward,
tank you very much,
As I said, I know how to calculate SD and variance and what sigma is, that was not my question.
My question was difference between two approaches of SD in roulette.
1 Standard deviation of bet and
2 Standard deviation of well frequency for some particaular bet.
Kind regards.

My professor explained it this way. Now I understand the difference.
Let's use 18/37 as the example for one spin
#2 method is the BSD (binomial standard deviation) N*P*Q is the variance. easy stuff. Now take the square root for the SD.
sd = 0.499817352
#1 method returns 0.999634703
(For a wager that pays x:1 with a probability of winning p, the standard deviation (per unit bet and per 'root decision') are:
std = (x+1)*Sqrt[p*(1-p)])
You should see the factor between the two values is 2.
Because BSD treats each outcome (Success and Failure) as 1 or 0
But for the bet, we need to be able to treat S and F as 1 and -1
So, for the sd of the bet we must double the BSD value when p = 18/37
when p = 1/37 the factor is now 36. Do you see why? (35+1)
when p = 12/37 the factor should be 3. Do you agree?
Roulette Spin Results List
Now you have some homework to completeIn summary, one can use the BSD formula for the sd of the bet, but you need to know the *factor* to multiply by.
It is easy once you do it a few times. ;)

Hehe :D
Now that was very well explained and easy to follow!
I see now, Binomial SD doesn't care about payout so the result is low, per one spin this is SD =(1PQ) ^ 0,5
While, when calculating for the bet, result per one spin is: SD = Payout * (1PQ) ^ 0,5
Thank you very much Sally for this valuable explanation.
Much appreciated!
Have a nice day :)

There still is one piece of the puzzle missing. I thought you might ask about it.
Maybe you already know it. So then this is for all that follow.
BSD = (N*P*Q)^.5 where Q = 1-p
Betstdev = (x+1)*Sqrt[p*(1-p)*N]
BetSD = Bet * Payoff * (N*P*Q)^.5 (Payoff = (x+1) where x = the payoff of X to 1)
Most BetSD values are shown for 1 unit, 1trial so you can just take N^.5 and go from there.
So, the Bet * Payoff completes the formula.

Hello again,
Yeah, I didn't think about that, cos what I wanted was general result for 1 chip in one or more spins.
Just to be sure, let's say if we calculate SD for 100 spins where we're flat beting 2 dollars on each of some 7 numbers combination then to solve this we do it so:
SD = 2$ * 36 * ((7/37) * (30/37) * 100) ^ 0,5 = 281,99$
Which means that we may expect a SD of 282$ around the mean in these 100 spins? where mean is (2$ * 7) * -0,027 *100 = -37,8$
I my equation and conclusion correct?
Thank you!

Correct.
You could have checked yourself and solved it for 1 trial then multiplied that result by 10.
2 handy formulas.
house edge = (x+1)*p - 1
standard deviation = Bet*(x+1)*Sqrt(p*(1-p)*n)
Another way to use the formulas for the (x+1) is to figure the payoff as (x to 1) +1
This would make it easier to calculate the combined house edge and variance of different multiple bets, if you want to do that.
Remember we can add ev and variance, not he and sd.
stdev = Total Bet*(x+1)*[Sqrt(p*(1-p)*n)]
what is x?
since there are Only 2 possible outcomes (that is what Binomial means)
-$14 loss or $58 win
58/14 would be the 'to 1' value (you are paid $58 for every $14 total bet)
58/14 + 1 = 58/14 + 14/14 = 72/14
$14*(72/14)*Sqrt(p*(1-p)*n) = your answer.
Also remember all this is just an approximation to the binomial distribution.
You can easily use that function in Excel. (Number of trials below 1000 before more error starts to creep in)
=BINOMDIST()
with 19 wins and 81 losses you will have exactly a -$32 result
with 20 wins and 80 losses you will have exactly a $40 result
(see the $72 difference)
Now, probability of any win after 100 trials is 43.0852% using the binomial distribution.
Using the normal distribution we get
0.446630352 showing the error to be on the high side.
Once I get my Excel set up in my new computer I can show you how to use that function if you need some help.
You should be able to crunch the numbers yourself now.

The best way to calculate the standard deviation in roulette is by recording 5000 spins. Most numbers will hit a very even amount of times. The average number of hits for each number will give you your base line for example if the all the numbers seem to hit an average of say 39 and two or three numbers hit say 49 or 59 times your standard deviation for the most often hit numbers would be 10-20. Some numbers will hit quite a bit more than the other numbers.

I have 6 wheels I have recoded 5000+ spins. I know the identifying mark for each wheel and I know how much I should bet per spin based on my bankroll and the standard deviations for my biased numbers on a biased wheel.
I dont get to play them very often because they are European style with single zero but when I do it pays quite good. Its a euro wheel how could it not lol.
