Like all forms of gambling there is normally a mathematical formula or system behind it all and playing a game for fun usually results in a loss of money, but playing a game systematically can yield good winnings. Remember, the casino's don't want you to win, but there are ways to increase your odds.

Casinos make all their profit from the blind luck gamblers and their four leafed clovers, but fortunately for you, you're making a proactive effort to actually use some scientific theory behind your method by reading this article.

So why use a roulette system? Most people think roulette is a game of chance, but there are certain laws and systems that can be applied in order to come out on top consistently. Nothing in life is truly random, there's cause and effect and there's probability.

Flip a coin 100 times and you'll probably get each face about 50 times depending on the cause of the wind, or power of the flip etc. Similar laws, rules and formulas can be applied to your roulette system to increase your chances of striking it big, or at least going home with more cash than when you arrived.

Now the laws of probability themselves suggest that people with degrees in maths, with mathematical minds are more likely to understand and be successful with the formula that goes in to a roulette system but they are that simple, any average Joe - including you (although you may be an above average Harry) can use them.

Perhaps the simplest, yet most logical and arguably effective roulette system is the old Martingale approach. (The what?) Exactly, this has been around for years, proving that there will always be blind luck gamblers with four leaf clovers who have no idea about such systems or who don't actively seek them out - meaning there will always be money for you to win. This roulette system simply means that you cover your losses.

Firstly pick a comfortable wager that doesn't break your balance right away, for example $10 and put it on even. Spin, if it's even hooray you've got $20 back. Now the rule is to only bet the same amount again, usually on the same number. So bet even again and again and again.

If you lose a round, use the double back system. So if you bet $10 and lose, bet $20 so that if you win then you are automatically "back in the game." The reason I say pick a comfortable wager is because you may hit a bad chain and have to keep doubling back. If you were too greedy to begin with you may go broke. Generally speaking you can also apply the laws of probability and alternate between odd and even (keeping the same wager).

This is a very simple roulette system and there are hundreds of others out there that are more complicated and take longer to fully grasp.

The single most important rule in regards to your roulette system is to stick with it. Don't get angry and bet a huge sum, and don't become greedy!
