How Many Roulette Numbers
There are 37 numbers on the wheel that lose, and 1 bet on the wheel that will win. But the bet only pays out 35 to 1, not 37 to 1, so the house wins more often than it loses. A split bet offers you odds of winning of 18 to 1, but it pays off at 17 to 1. I could list all of them, but you get the idea by now. A roulette wheel in the U.S. Contains 38 equally sized spaces. The wheel is spun and a ball randomly lands in one of these spaces. Two spaces are green and have numbers 0 and 00 on them. The other spaces are numbered from 1 to 36. Regarding the main question: how many series of 8 unique numbers with no repeats can come one after another, in my experience with playing latest 10 unique numbers (I have not simulated 8 yet), 2 or 3 in succession can be seen in every thousand spins and upto 6 in a million.
For 300 spins the probability that a particular number will not show up is (37/38)^300 = 0.0335%. That's pretty small, but not zero. If you repeated this 300 spin experiment 3000 times, you'd only expect to completely miss your number on one of the trials.
I am trying to figure out how many spins would u say is it where a number statistically would have to come up
It is all about the degree of certainty.
For a 38 number wheel.
From http://wizardofvegas.com/member/nope27/blog/:
'The below table is for the probability of NOT hitting 'at least 1' number in x spins.
formula used from:http://wizardofodds.com/askthewizard/roulette.html
question #2 at WoO.
Wizards' Example: for 'at least 1' number NOT hitting in 200 spins
Sum i=1 to 37 [(-1)^(i+1) × combin(38,i) × ((38-i)/38)^38] = 16.9845715651245%'
I have expanded the table below from the above blog.
I have also run 1 million spin simulations and have seen many numbers that did not appear in 500 spins.
I would say from the table 1000 spins would be a hard one to ever witness.

For a particular number not to come up in 300 spins I would agree with PapaChubby: (37/38)^300 = 0.0335%.
For at least one number not to come up, I think that guido111 has a good grip on the problem based on a solution given by the Wizard for the case of 200 spins, however the Wizard's logic may not be easy for everyone to follow. Here is another approach based on counting the ways the balls can be distributed to the numbers.
We assume that both the balls and the numbers are distinguishable. The numbers are distinguishable because they are all different and the balls are distinguished by the order in which they are thrown. There is a function T(m,n) that gives the number of ways that m distinguishable objects may be distributed to n containers such that every container has at least one object. The number of ways of distributing m objects to n containers without restriction is nm so the probability that all numbers will have been hit by at least one ball is T(m,n)/nm. Subtract this from 1 and that is the probability that at least one number will remain unhit. For m = 300 and n = 38 this evaluates to 0.01267822135, which agrees with guido111's result.
It is always possible either for a particular number or for some number or other not to come up based on the inequality T(m,n) < nm.
The T function is discussed in several books on combinatorics. I shall be glad to provide a bibliography if anyone asks.
Its the same with a roulette wheel, if you don't specify a particular number that must hit then there are lots of spins that can go by and there being some surviving number that is unhit is still quite likely.
Ofcourse I don't want to know what number will NOT hit on that next spin, I want to know what number will hit on that next spin.
You are using a different (correct) formula to account for all possibilities.
I use to play a method (it did quite well for sometime), I tracked all numbers until only ONE left unhit. When I got to that point, I started a 110 progression on that one number. It was around a $3,600 BR. Like I said, I made ALOT of money BUT as usual, it slowly tanked. The 110 combined with how far back it last hit was well over 300 spins and on multiple occasions I might add so I stopped playing it. That particular method slowly lured me away from playing sleepers/due.

That's why several gambler's like you have become victims of the 'gambler's fallacy'.
.......and you Keyser are low on gas, better stop. Which city this week? I heard the 21/33 is hitting ALOT at a casino in Tucson. Pack up the car and away you go!! (LMAO) Talk about putting all your eggs in ONE basket.

One of the most fascinating things about roulette is the variety of bets that you can place. Before you play roulette, especially for real money, it is best to have a clear understanding about the different bets and their payouts.
On this page, we’re going to go through every single bet type, including the more advanced Call/Announce Bets. If you want to see a quick “cheat sheet” with all of the different payouts in a graph for quick reference, you will find it on our page on roulette payouts.
Outside Bets
Outside bets can be found on the “outside” of the roulette table and the cover a large portion of the wheel, but the payouts are low.In total, there are 5 different kinds of outside bets which are the following:
Red and Black – There are 18 red numbers and 18 black numbers.
Odd and Even – There are 18 odd numbers and 18 even numbers.
1-18 and 19-36 – Pretty self explanatory, both of them cover 18 numbers.
The three above bets are “even money bets” because you double your money if you win e.g. bet £2 on black, win £4 back. Each of them covers just less than half of the table due to the addition of the 0 and in the case of the American game, 0 and 00.
Dozens – There are three dozens on the roulette table, 1-12, 13-24 and 25-36. Each of them covers 12 numbers which equates to just less than a third of the wheel.
Columns – These are similar to the dozens; there are three columns on the table and each of them covers 12 numbers.
Inside Bets
Inside bets can be found on the “Inside” of the table and they cover less numbers but the payouts are higher.
Straight Up Bet – This is a bet on a single number.
Split Bet – This is a bet on two numbers that are next to each other on the roulette table (not the roulette wheel).
Street Bet – Bets on three numbers that are a Street on the roulette table. For example, 1,2,3 is a Street, 4,5,6 is a Street and so on.
Corner Bet – A bet on four numbers that make a square on the roulette table. For example, 1,2,4,5 is a Corner bet.
4 Number Bet – Bets on 0,1,2,3 at the same time. Only available on European and French roulette.
5 Number Bet – Bets on 0,00,1,2,3 at the same time. Only available on American roulette. This is also the worst bet in the entire game because of the unfair payout – avoid it.
Double Street (Line Bet) – This is the same as the Street bet except it covers two Streets at the same time rather than one.
Call Bets
The Call bets, or Announce bets as they’re sometimes named, aren’t available on every roulette game and often they’re overlooked by players because they either don’t understand them or they would simply rather bet on the more simple bets above.
Before explaining what the Call bets are about, it’s worth noting that the layout of the roulette table and the roulette wheel are different. For example, as you go around the roulette wheel, the numbers are seemingly in a random order, they don’t go 1,2,3,4,5,6 etc.
The Call bets are a way of betting on sectors of the wheel. If you think of the roulette wheel as a pizza, the Call bets are a way of covering a slice or multiple slices if you want to.
Voisins Du Zero
This is a bet that covers 17 consecutive numbers on the roulette wheel, starting from 25 and working your way around the wheel to 22. They’re also known by some as neighbours of the zero because the zero is (almost) in the middle of these numbers.
The actual Voisins Du Zero bet is covered by just 9 chips and it is done like this:
2 chips on 0,2,3 street
1 on the 4/7 split
1 on 12/15 split
1 on 18/21 split
1 on 19/22 split
1 on 32/35 split
2 chips on 25,26,28,29 corner
Tier
The Tier bet is 12 numbers that are next to each other on the roulette wheel. The numbers are as follows: 27,13,36,11,30,8,23,10,5,24,16,33. The bet is covered by betting on 6 split bets at the same time which are:
5/8 – 10/11 – 13/16 – 23/24 – 27/30 – 33/36
Orphelins
This is a bet that covers 8 numbers, three that are next to each other on one sector of the wheel, 5 that are next to each other on another sector. The numbers are as follows: 6,34,17 and 1,20,14,31,9. The Orphelins bet is covered in the following way:
Straight bet on number 1
Split bet on 5/9
Split bet on 14/17
Split bet on 17/20
Split bet on 31/34

Neighbours
The Neighbours (sometimes spelt Neighbors depending where you are in the world) are 5 number bets of your choosing. Basically you pick your number and then you bet on that number and the two numbers that are on either side of it, making it a 5 number bet. A very easy way to cover large sections of the wheel. Some casinos will allow you to increase the size of your neighbours, up to eight either side of your number, making it a 17 number bet in total.
Final Bet
How Many Roulette Numbers Roblox
You may have a hard to finding this option online because very few casinos offer it. With this bet, you start by picking a number from 1-9. Once this is done, a bet will be placed on all numbers ending with the number that you chose.
Does this sound confusing? If so here is an example. If you picked 6, a bet would then be placed on the following numbers: 6, 16 and 26 because they all end in 6.
One Final Thing On Call Bets
Both online and offline, the Call bets are normally accessible via what’s called a Racetrack and in some land based casinos, you “Announce” the bet out loud rather than placing chips on it, hence why they’re sometimes referred to as Announce Bets.
If you would like to see the Call bets and try them for yourself, have a go on our free roulette pro game which has all of them available via a menu in the bottom left hand corner rather than the conventional Racetrack.
