No, there are no patterns in roulette. Each spin of the wheel is completely independent and doesn’t influence the next in any way. Roulette’s unpredictability is one of the reasons it’s so popular, and in modern online casinos, this randomness is guaranteed by RNG (Random Number Generator) systems. These systems are frequently audited by trusted authorities like eCogra, Gaming Labs International (GLI), and iTech Labs to ensure fairness.
What’s more, casinos licensed by bodies like the UKGC, MGA, or Curacao are held to strict standards of fairness. They are required to ensure that every outcome is random and unbiased. Failing to meet these requirements can lead to losing their licence, meaning they take this very seriously. In short, there's no way to “read” roulette—each spin is a fresh and unpredictable event.
