Roulette is a fairly straightforward game to understand. There is a wheel that spins a ball until that ball lands in a numbered pocket ranging from 0-36. In American roulette, there is a 00 as well. The house advantage in the European roulette games are at 2.37% or 1.35% when "la partage" rule is in effect. The American version with a 00 has a house edge of 5.26%. There is much speculation about how can you create a system that will take the edge away from the house?
In short, you can't guarantee anything in this game of chance. Roulette is a purely random game and every time you spin the wheel it is as mathematically possible for the ball to land in any of the slots as it was the time before. However, this has not stopped the wide world of "experts" in producing a bevy of roulette systems for you to choose from.
There are some systems that are software systems that tell you which combinations to place your bets. There are some systems that are devices that you actually wear into the casino so that the gadget can read the wheel! Can you imagine! And the real kicker is that it is not illegal in most casinos, so I guess that is proof positive that the house does not believe the game can be beat.
Most of the systems that you can buy online have been debunked. There are some sites online that will review dozens of failed roulette systems, except one. Can you guess who created the one system that works? Of course it is the author of the same site! There is a lot of lies and heartbreak waiting for those who believe there is a fool-proof system.
For strategies and real tips on how to win, you can find a wealth of information. One fun way to feel more like an active participant in the game and not just randomly betting is to watch for trends. If there have been a long number of red wins, then you may feel the heat switching to the black pocket. There are forums online and free game rooms to perfect the winning strategy. Remember the old adage: If it is too good to be true, then it probably is.
