Roulette strategies are different from just about everyone you talk to. Each experienced player has their own way that might win or might not. Being that there are no perfect strategies that win every time, you are going to have to develop a way of thinking that benefits you the most.
Where Roulette Strategies Begin
When developing a roulette strategies, you should first think about what is going to hurt you as opposed to what is going to win for you. Roulette is a game that players can easily contradict themselves which basically prevents them from winning. Think about what you are betting on as a whole. Then look at the payouts if you win. What you might not realize is that many of your bets will not cover the bet you have placed down. That means that you will lose almost no matter what.
Roulette is a game that has the big payouts inside and the smaller ones on the outside. The reason for the discrepancies in payouts is the odds of hitting your bet. Your chance of hitting an inside number is 1 in 38 while your chance of hitting red or black is almost 50/50 (take in account the two green squares). Most experts will tell you that if you play both outside and inside, treat them as separate entities when betting.
Watching the numbers is always a good way to play. From personal experience, go with the streaks. It might seem to be against the odds, but for some reason the streaks just love to continue on. You might lose, but if you stay with the hot color, it might just make you some serious money.
