Roulette is often considered to be one of the easier games to play in the casino. This isn’t exactly true, and those players are not employing the best of roulette strategies.
Roulette strategies it’s mean methods by which to play, but simply as a guide. Strategies do not claim to mathematically beat the house at all, they usually offer simpler advice on things like setting win and loss limits. 
One of the best roulette strategies you can play is one that revolves around bankroll management. I make a example:
If you starts with a bankroll of USD1000. To protect your investment you must set a loss limit of USD1000, their entire session bankroll. This means if you looses this money in the course of playing, they have set a personal rule to not return to the session after getting more money, also you must sets a win limit of USD3000, meaning if you manage to go USD3000 over you original bankroll they will stop playing.
This is as basic as roulette strategies get, but it is extremely effective, if you learn to follow your own rules.
To win at roulette you must learn to stop when you win and when you lost.
