The mathematical house edge in roulette is determined by the number of pockets on the wheel. European roulette, which features a single zero, typically maintains a house edge of 2.70%. In contrast, the American wheel includes both a single and a double zero, increasing the house edge to 5.26%. French roulette is also a recognized variant, with European and French versions typically featuring 37 pockets (0-36), while American versions total 38 pockets. Standard payouts for a single number are generally 35 to 1.

While the use of a live dealer or a Random Number Generator (RNG) changes the visual experience, these factors do not alter the fundamental house edge. In the United States, online casinos are regulated by bodies such as the Federal Council and State Gaming commissions. Licensed real-money platforms utilize RNG audits from independent agencies, including eCOGRA, iTech Laboratories, and GLI, to ensure fairness.

Regulated platforms in both the United States and the Netherlands provide responsible gambling tools, such as deposit limits, self-exclusion options, and fact-checking measures to protect customers.
