The very first step in designing a roulette system is clearly defining what makes it different to random bets. After all, if your system wins just as frequently as random bets, it’s no different to random bets.

But frequency of win mostly depends on the type of bets you make, or more specifically the amount of numbers you cover. This is because on the European world there are 37 numbers, which means the odds of one number winning are one in 37. Of course with the American 00 wheel, the odds of winning are 1 in 38.

## Real Wheels Vs Online RNG Wheels

Are real physical roulette wheel is different to the random number generators used by most roulette online casinos?

Yes, absolutely. Obviously real wheels are physical and exist in reality, whether they are viewed live by WebCam, or right in front of you.

Random number generators are what determine the winning number for software roulette. This kind of roulette has no physical roulette wheel. It is just a game, with computer animations. In such a case, there are no physical variables that determine the winning number. There is no dealer to release a ball, because there is no ball.

But can you actually notice any difference in the spin outcomes? This depends on the patterns you are looking at. If you look at something like reds and blacks, odds or evens, then you aren’t likely to notice any difference. But if you consider real physical variables of the real wheel, and correlate them to spin outcomes, then you may very well find real patterns. And I mean patterns that exist not just in your head. If you attempt to look at the same kind of patterns with the random number generator spins, they won’t exist. So the differences depend on what you are looking at. After all if you’re looking at something that doesn’t really exist, you are not going to find it.

Having said that, if the quality of the random number generator is high, then there won’t be any usable patterns. So if you intend to play roulette as a professional, you need to focus on real wheels. If you intend to play with random number generators, then you need to exploit the random number generator itself. You can find flawed random number generators, but they are very difficult to assess because you need potentially hundreds of thousands of spins. Even then, the edge you get may be insignificant.

## Investigating Spin Outcome Fairness

Once you have determined where you intend to test your system, you need to assess the fairness of the spins. Generally you can assume that the spins are fair if a real and physical roulette wheel is used. Of course it’s entirely possible that hidden magnets are used to avoid paying you out. But this is highly unlikely, especially at the casino is regulated.

So I’m going to assume you are testing the fairness of random number generator spins. Unfortunately proper tests require hundreds of thousands, if not millions, of spins. This makes proper testing to be quite impractical. But one anomaly you can look out for is that low quality random number generators tend to frequently repeat numbers. This makes them much easier to beat than fair random number generators.

A prime example is Microsoft Excel. What happens is when numbers are randomly generated in an Excel database or spreadsheet, the computer’s internal clock causes many numbers to repeat. Repeats are very obvious, and you might see something like 0, 0, 0, 5, 5, 5, 2, 2, and so on.

So if you are thinking to use Excel to generate random numbers, don’t. You’ll just get an unrealistic idea of the effectiveness of your system.

Likewise, many operating systems tend to have similar flaws. This includes Centos and other operating systems used for websites. But generally, real casinos where real money is wagered do not have these flaws. It is very important to test with realistic spin results.

## Beware Of Dishonest Casinos

Many online casinos provide prospective players with free games to test their systems. But there are numerous rogue casinos that give players an advantage in test sessions. The idea is to give players an unrealistic idea of how effective this system is. So when the player wins thousands in test sessions, they believe they’ll achieve the same results when betting for real.

So as a general rule, never test your system and any real casino, or any website that promotes casinos. The exception is if you can somehow verify the fairness of the spinning outcomes.

## Online Games and Roulette Simulators

The majority of roulette players use various free online roulette games and simulators to test their systems. The problems with this are they are games that often do not use their random spins. I know one particular online roulette simulator which gives no disclosure regarding the source of spin outcomes. Yet it’s quite popular with gamblers who want to showcase the effectiveness of their system.

The problem with this is the same as testing on any unrealistic game. The random number generator may be flawed, and won’t give you a realistic idea of the effectiveness of the system. This is particularly the case if your system relies on repeating numbers, for reasons previously explained.
