A lot of people provide guidelines on how to always win roulette. However, there is no way to guarantee oneself earnings at the roulette table. If you play Roulette long enough, you'll ultimately have a streak of at least 15 winning bets in a row. Remember that this is a game of chance, there is no way predicting that you will hit big on the next spin. What you need to learn is how to manage your bankroll properly. Learn when to call it a day. Furthermore, walk away while you are still ahead.
