The game is designed to be random, and the odds of each number or color coming up are the same on every spin. There is no strategy or pattern that can reliably predict the outcome of a roulette spin.
Online casino roulette is designed to be completely random, as it is governed by random number generators (RNGs) to ensure fairness. The RNGs are regularly tested and audited by independent third-party organizations to verify their integrity and randomness.
