My advice is just to try playing somewhere free online for awhile until you get all the rules down. There are plenty of places that you can do this, and in the long wrong you won't lose anything, but you gain a lot of knowledge of the game. Good luck, have fun!
Advice to help you win? There is none.
Roulette is 100% luck. It doesn't matter how you place your bets, there is absolutely no way to beat roulette in the long run.
Go along with money you can afford to lose. Hope to win something, but expect to lose.
