System 35:1
Many players bet on the roulette wheel down your favorite numbers because they are in awe of the course 35 to 1.
American double zero roulette with casino offers a statistical advantage 5.27% in French Roulette 2.7% (which is preferable). All this leads to numerous vain attempts of players who take it seriously and want to get into the narrow circle of professionals. It is necessary to introduce the strategy of betting on numbers, known as "System 35: 1.
This system is based on something known as "law of uneven distribution.
By this I mean the tendency of the numbers on the roulette not be repeated.
I guess you will agree that in the course of any of 38 spins will not fall all the numbers. In the series of 38 spins generally repeat third of the numbers in which some numbers are making two, three or more times, while others do not fall at all.
This phenomenon is not just a theory but a fact verified, supported by the experience of tens of thousands of spins. In which leads to interesting conclusions. Strange as that often the numbers tend to fall mnogokratno continue to do so. This system was invented by the method of trial and error.
First you need to determine the limit of profits and losses.
Your maximum bet on one spin should be equal to four times the potential profit at the low stakes. For example, if the minimum amount (pledge) is a dollar, the profit margin would be $ 35. 4 x 35 is 140, so obshata amount of betting on a turn should be a maximum of $ 140.
Proposed minimum net profit should be 1.5 times the amount bet. That is, if you bet $ 140 a spin, the planned net profit should be $ 210. You will need something to write to his note of the numbers have fallen, or exceptionally zeros as appropriate - double zeros.
As soon as you have at least two numbers that have fallen twice, you can run. Bet on any number that has fallen more than twice, and add new numbers, which have fallen by more than twice. Continue this way until you get 6 different repeating numbers that work for you.
Within a spin Do not play more than 6 numbers. The bet is always the same, say one dollar each day until one of them won.Once this happens, return to a dollar and earn another 35. Then bet profit in such a way that 36 bucks split between the original numbers. According to the number of numbers and divide the sum, for example - po $ 18 if the numbers are two, $ 12 if the numbers are three, 9-if four in 7 if five or six, if the numbers are 6. If any of your numbers comes up twice in succession, your profit will be between 210 and 630 dollars! In this situation you can leave the game.
If you start using this system often, you'll notice that you start earning only after losing about half of the capital that you have decided to make a maximum bet on one spin. So if you still have $ 70 and earn at least $ 210, have a total of 280 dollars (minus 140, which have had in the beginning), that you leave with a net profit of $ 140. You doubled your money.
You must be wondering what happens if no number not fall twice consecutively. In that case, go back to betting on a dollar until you win, then continue to follow this method. Someone might seem that the system is too risky and likely to win is too small. Observe, however, how the numbers fall - will be surprised how often repeated. This is a system that calculated risk when you can earn a substantial amount.
Note:
If you are a player who does not like to risk, you can complete immediately after the first win. Just take their money, not divide them between the numbers and do not bet. But it might not be such a good idea, because you are left with only part of the money you could win the next spin. This is the dilemma which the player decided individually according to their own financial and emotional reserves.
Two And More
This system 
is very simple and requires only patience
and healthy nerves (but whatnot Tues dneshno time to iziskva). Tova's systems,
based on a more frequent repetition of certain numbers.
As you know, roulette relies on probability theory according to which
a large number of spins the numbers should fall to approximately
same number of times. But what about when we have a few spins?
Overall, a bit different. Surely you will agree that numbers are falling
sporadically - nyakoi in honor of other orders of magnitude.
This may be due to chance or to the surface roughness
of real Roulette - sometimes the error in the software.

So the method is as follows:
1. Save gradually winning numbers of 37 spins
     (In the case of French roulette with one zero), eventually turns 38
     (If you play American village two zeros).
2. Take the numbers recorded those who have fallen 2 or more times
    within these 37 spins.
3. Bet on these numbers the same amount over the next
    37 spins. Even when you win, continue to bet on the same
    numbers still the same amount as they are likely to fall more than once.
4. After 37 spins, which you are betting, stop playing,
    save your next 37 winning numbers and povetorete point 2,3 and 4.

You'll notice that during the series of 37 spins always bet on average
Numbers 6-11 and earn an average of 9-13 times for a series that should be enough.
System Of 5 Numbers 
  Under this system is good to prepare a large amount of money (for safety).
For the actions described, you will need 510  , you can try a smaller amount
but one are feeling more secure when it is ready.

Choose your chance (your favorite) 5 numbers , from 37 possible, which gives you
roulette and bet on them constantly. This system will hold the game in 17 spins
during which should fall at least one of the numbers on which you bet.

1. Pledge a  5 numbers - win: € 31 , if you lose, continue:
2. A pledge of  5 for each other as gifts - diasporic: € 26
3. A pledge of  5 for each other as gifts - diasporic: € 21
4. A pledge of  5 for each other as gifts - diasporic: € 16
5. A pledge of  5 for each other as gifts - diasporic: € 11
6. A pledge of  5 for each other as gifts - diasporic: € 6
7. Pledge a  5 numbers - win: € 1 (bad luck)
8. Pledge 6  to 5 each other as gifts - diasporic: € 151
9. Pledge 6  to 5 each other as gifts - diasporic: € 121
10. Pledge 6  to 5 each other as gifts - diasporic: € 91
11. Pledge 6  to 5 each other as gifts - diasporic: € 61
12. Pledge 6  to 5 each other as gifts - diasporic: € 31
13. Pledge of 11  for 5 numbers - diasporic: € 156
14. Pledge of 11  for 5 numbers - diasporic: € 101
15. Pledge of 11  for 5 numbers - diasporic: € 46
16. Pledge of 16  for 5 numbers - diasporic: € 146
17. Pledge of 16  for 5 numbers - diasporic: € 66

So far, you bet 17 x 5, ie 85 numbers. Roulette has 36 numbers plus zero.
The probability that it will not drop any of your numbers is not very large, right?
If you have more capital, you can still bet, but profits and so
not bad, so I'd recommend you to stop after the first win.
