This is what I've personally learned trying to use this strategy, you absolutely have to have enough money on the table ready to go to cover the losses that you will incur until your color comes up. If you do not have enough money ready to go the first streak of bad luck will wipe you out.

The key to using this type of strategy is to place a bet on the color of your choice. If the ball lands on your color, lucky day and the bet stays the same. Now if the ball lands on the opposite color you must double your bet. The idea behind this is that the odds of the ball landing on the opposite color diminishes every time that it does thereby making the odds of the ball landing on your color better and better. After a few times of the ball landing on the opposite color, and assuming that you've doubled your bet every time, when you win you'll be one up your original bet.

Now this is the trick and this is where I lost it. You absolutely have to have enough money on the table, ready to go, to double your bet each and every time that you lose. Now to be honest, I have never tried this technique in a traditional casino and I'm not even sure that they would allow this type of betting strategy to be used. I suppose it depends on where you are playing. I have used this strategy on online casino sites and it works.

The only problem is if you get involved in a lesser site with a type of random number generator that doesn't exactly duplicate real world scenarios. If they are not absolutely right on the money then the odds and probabilities are almost worthless. This means that a player can have almost an endless streak of the ball landing on the opposite color without winning their money back. If this is the case then even the largest bankroll won't be able to save you.

At any rate, there are numerous methods on the Internet to help you with your chosen game. Some are based in logic and solid mathematical principles, and some are not. The main pitfall that an online casino player must look out for is simply that many online casinos do not accurately depict actual game play to the point of not allowing any particular mathematical stratagem to work like it's supposed to.
