There are more systems devised to beat the roulette wheel than any other game. A system may give you an edge, but don't expect to systematically play your way to riches off the casinos.
For one thing, everything considered, it is a very difficult task. For another thing, it's unlikely that the casinos will sit back and do nothing about it.
Simply aiming to win to stay ahead at all times as a primary objective, even by a small margin, is a more realistic goal and a great achievement.
In a game of chance, using a system is no guarantee of winning, but a well-devised roulette system can streamline your losses, control your winnings and have a strategy that will give you an opportunity to be a winner.
Roulette systems that have a strategy to win most of the time, but lose out overall, are not winning systems. A winning system is one with a strategy to make you win overall and keep you ahead at all times.
It has been shown time and again that roulette systems that rely on probability have failed to produce consistent successful results. That is because roulette is not a game of probability.
At roulette, each spin is a new spin and the outcome is never determined by prior spins. Therefore, the probability for a possible outcome is the same for each spin and a probability advantage cannot be generated.
For example: Which outcome has a higher probability after eight successive Blacks? Black again or Red?
The probable answer is Red. Wrong! After eight successive Blacks, a Black is as likely to come as a Red. The wheel has no memory and it does not keep record of previous results.
This is what many gamblers find hard to believe. This misconception has been around for many years and will probably be around for as many more years.
It is known as the gambler's fallacy. In theory, roulette may be looked at as a game of probability and that the casino advantage of 5.26% with a double zero wheel (2.7% with a single zero wheel) makes the player a definite loser.
In practice, as far as the player is concerned, roulette is a game of luck and the player has a chance to win.
If you were to bet $5 on Black for 38 spins on a double zero wheel, in theory you would win and lose every other spin and after 38 spins (which is about an hour of play at a busy table) you would lose $10 for twice the zero outcome.
In practice, during an hour of play, at some stage, if you were lucky, you would be up, and if you were unlucky, you would be down by more than $10, and deciding when to quit will determine the amount of your winnings or losses.
Consider this: If there was no casino advantage and you were paid 37 to 1 (36 to 1 for a single zero wheel) instead of 35 to 1 on numbers and didn't lose on the outside bets when the outcome was zero, during the past several times that you have played the roulette, would you now be even with your money? Chances are it would not make much difference. You would still be either winning or losing and by much more than 5.26%.
The reason is that at roulette, by far the two major factors that determine how much you win or lose are: (1) Your luck on the day and (2) Deciding when is the best time to quit.
Therefore, for a roulette system to have a degree of success, it has to be linked to luck and telling you exactly when to quit. Additionally, a good system has to take into account other obscured, but important advantages for both the casino and the player.
To the casino: The player's natural greed for money; the player's lack of self-discipline; and time (the longer you play, the higher the chances that you hit a streak of bad luck and run out of money).
To the player: You can choose when and where to bet. You can choose and vary the amount of your bet. You decide when to quit.
Now, if you agree to all that has been said so far and give it some thought, you could well apply a roulette strategy yourself that is linked to luck.
Additionally, if you are able to weaken the above-said three casino advantages (not easy) and make good use of the player's three advantages, chances are, in the long run, you may come out an overall winner.
If you try to beat the roulette wheel mathematically, it's unlikely that you will get anywhere, even with no casino advantage (no 0-00). Mathematics and gambling don't mix. In mathematics you know exactly what is going to happen.
Gambling is the exact opposite; you never know what is going to happen - otherwise it wouldn't be gambling.
