Westio European vs American Roulette
Key Differences: The Wheel and Table Layout
The most fundamental difference between European and American Roulette lies in the wheel itself. A European roulette wheel features 37 pockets: numbers 1 through 36 (alternating red and black) and a single green zero (0). The American version, however, has 38 pockets. It includes the numbers 1-36, a single zero (0), and an additional double zero (00), both colored green. This extra pocket significantly alters the game’s odds. The table layout also differs; the American table has a separate betting area for the ’00’, while the European layout does not.

House Edge and RTP: Why It Matters
The addition of the double zero on the American wheel has a direct and substantial impact on the house advantage. The house edge represents the casino’s statistical profit margin on all bets over time. In European Roulette, the house edge is a much more player-friendly 2.70%. This translates to a theoretical Return to Player (RTP) of 97.30%. American Roulette, with its extra pocket, carries a house edge of 5.26%, resulting in a lower RTP of 94.74%. This means that, statistically, you will lose money faster playing the American version. For example, a straight-up bet on a single number in European Roulette pays 35-to-1 with odds of 1/37 (2.70% house edge). The same bet in American Roulette still pays 35-to-1, but the odds are worse at 1/38, creating the higher 5.26% edge.
The “En Prison” or “La Partage” Rule
An exclusive feature often found in European Roulette is a special rule that applies to even-money bets (like red/black or odd/even) when the ball lands on zero. This rule comes in two common variations: ‘La Partage’ and ‘En Prison’. Under ‘La Partage’, you lose only half your bet if zero hits, significantly reducing the house edge on those bets to about 1.35%. The ‘En Prison’ rule gives you the option to either surrender half the bet or leave it ‘imprisoned’ for the next spin, where it can either be released or lost entirely. These rules are almost never offered in American Roulette, further cementing its higher house advantage.
| Feature | European Roulette | American Roulette |
|---|---|---|
| Number of Pockets | 37 (0, 1-36) | 38 (0, 00, 1-36) |
| House Edge | 2.70% | 5.26% |
| RTP (Return to Player) | 97.30% | 94.74% |
| Special Zero Rule | Often La Partage/En Prison | None |
Which Version Should You Play?
From a purely mathematical standpoint, European Roulette is the unequivocally smarter choice for any player focused on bankroll management and maximizing their playing time. The lower house edge directly translates to better long-term value. While the core gameplay is identical, the presence of the double zero makes American Roulette a much more expensive game. Always seek out the European wheel, especially when playing online. For instance, a platform like Westio casino typically offers both versions, allowing you to make the optimal choice.
Maximizing Your Play with Casino Bonuses
When playing any roulette variant, leveraging a welcome offer can provide extra value. A Westio bonus often comes in the form of a match deposit bonus or free spins. It’s crucial to read the terms and conditions, particularly the wagering requirements. Bonuses are ideal for games like European Roulette due to the lower house edge, as the playthrough requirements are easier to meet. While a Westio no deposit offer is rare for table games, it’s worth checking the promotions page. Sometimes, a specific Westio promo code might be required to activate a bonus package that includes bonus funds usable on roulette. Be aware that wagering on roulette may contribute less to bonus clearance than slots, often only 10-20%. While Westio free spins are typically for slots, the deposited funds you receive as part of a package can be used on the roulette tables.
Final Verdict and Strategy Tips
Choose European Roulette over American every time. To enhance your experience, follow these practical tips:
- Stick to outside bets (Red/Black, Odd/Even, High/Low) for the best odds of winning, despite the lower payouts.
- Set a strict loss limit and a win goal before you start playing, and walk away once you hit either.
- Never chase your losses; roulette is a game of chance with every spin being independent.
- Practice with free versions of the game to understand the flow and betting options before wagering real money.
- Always verify which roulette variant you are about to play—don’t assume it’s European.
By understanding these key differences and applying basic strategy, you can make more informed decisions and enjoy a better overall gaming experience at Westio and other casinos.
