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.
While it is theoretically possible to make a living off of playing roulette, it is extremely difficult and highly unlikely. Roulette is a game of chance, and the house always has an edge, which means that over time, the odds are in favor of the casino.
Say a single-number bet has a 35:1 payout, and you betR$1. If you win, you'll get your money back plusR$35. Another example: If you win aR$100 bet (for a 35:1 payout), you get a total of $3,600 ($3,500 profit plus theR$100 you initially bet).
