I believe there are no proven strategies to consistently win at roulette, as it is a game of chance with a built-in house edge. While betting systems like the Martingale or Fibonacci are popular, they do not alter the fundamental odds or eliminate the house advantage. These systems may offer short-term wins, but they also carry significant risk, especially with losing streaks. Since each spin is random and independent, no strategy can guarantee long-term success, and luck remains the dominant factor in roulette outcomes.
