The Odds of Winning Roulette vs Other Casino Games

For many Kiwis, the thrill of online casino games is undeniable. Whether you're spinning the reels of a pokie or placing your bets at a virtual roulette table, a key factor in your gaming experience is understanding the odds. While luck plays a significant role, knowing the probabilities behind each game can help you make more informed decisions and potentially extend your playtime.
In the world of online casinos, terms like ‘odds', ‘Return to Player (RTP)', and ‘house edge' are frequently used. These concepts are fundamental to grasping your chances of winning. This guide will break down these terms and explore the typical odds for popular casino games available to players in New Zealand, helping you navigate the exciting landscape of online gambling with a clearer perspective.
Understanding Casino Game Odds, RTP, and House Edge
Before diving into specific games, let's clarify the core concepts that determine your winning potential at any online casino.
- Odds: In simple terms, odds represent the probability of a particular event occurring. For instance, if the odds of winning a specific bet are 10 to 1, it means that for every 11 outcomes, you're expected to win once and lose ten times.
- Return to Player (RTP): This is a theoretical percentage that indicates how much of the money wagered on a game is paid back to players over a long period. For example, a pokie with a 96% RTP means that, on average, for every $100 wagered, $96 is returned to players, while the casino keeps $4. It's important to remember this is an average over millions of spins, not a guarantee for individual sessions.
- House Edge: The house edge is essentially the casino's built-in advantage, expressed as a percentage. It's the inverse of the RTP. If a game has a 96% RTP, its house edge is 4% (100% – 96% = 4%). The house edge ensures that, in the long run, the casino will always make a profit. Understanding the house edge allows you to identify which games offer better theoretical returns.
Pokies (Slots) Odds in New Zealand Online Casinos
Pokies are by far the most popular casino games for Kiwis, known for their vibrant themes, engaging features, and the potential for big wins. However, unlike some table games, pokies are almost entirely games of chance. Your “odds” of winning are primarily determined by the game's Return to Player (RTP) percentage and its volatility.
Most online pokies available to New Zealand players feature an RTP ranging from 92% to 98%. A higher RTP means a lower house edge and theoretically better long-term returns for players. It's always a good idea to check the RTP of a pokie before playing, as this information is usually found in the game's info section.
Beyond RTP, volatility (or variance) also plays a crucial role. High volatility pokies offer less frequent but larger payouts, while low volatility pokies provide more frequent but smaller wins. Your choice between high and low volatility should align with your bankroll and risk tolerance.

Roulette Odds: European vs. American
Roulette is a classic casino game where players bet on where a ball will land on a spinning wheel. The odds in roulette are straightforwardly calculated based on the number of pockets on the wheel and the type of bet placed. Crucially, there are two main versions of roulette, and understanding the difference is vital for New Zealand players looking for the best odds:
- European Roulette: This version features 37 pockets: numbers 1-36 and a single zero (0). The single zero gives the house an edge. For a single number bet, the odds are 36 to 1 (meaning you win 36 units for every 1 unit bet, plus your original stake back). The house edge for European Roulette is approximately 2.70%.
- American Roulette: This version has 38 pockets: numbers 1-36, a single zero (0), and a double zero (00). The addition of the double zero significantly increases the house edge. For a single number bet, the odds are still 36 to 1, but with 38 possible outcomes, your probability of winning is lower. The house edge for American Roulette is approximately 5.26%.
As you can see, European Roulette offers significantly better odds for players due to its lower house edge. When playing at online casinos, Kiwis should always opt for European Roulette tables if available.

Table Game Odds: Blackjack, Baccarat, and Poker
Table games like Blackjack, Baccarat, and various forms of online poker (played against the house) often offer some of the best odds in the casino, especially for players who employ strategy. These live casino games combine elements of luck with skill, allowing players to influence the outcome to some extent.
Blackjack: Often considered the casino game with the best odds for players, Blackjack can have a house edge as low as 0.5% to 2% with optimal strategy. This means making the mathematically correct decision for every hand based on your cards and the dealer's upcard. Without strategy, the house edge can be much higher. Learning basic blackjack strategy is highly recommended for any player in New Zealand looking to improve their chances.
Baccarat: This elegant card game is known for its simplicity and relatively low house edge. There are three main bets:
- Banker Bet: House edge typically around 1.06%. (A 5% commission is usually taken on winning Banker bets).
- Player Bet: House edge typically around 1.24%.
- Tie Bet: House edge is significantly higher, often around 14.36%.
For the best odds in Baccarat, always bet on the Banker or Player and avoid the Tie bet.
Online Poker (Casino Poker Variants): Games like Casino Hold'em, Three Card Poker, and Caribbean Stud Poker are played against the house, not other players. The house edge varies significantly between these games and specific rules, but generally ranges from 2% to 5% or more. While luck is involved, understanding the game's strategy (when to fold, raise, or bet) can help reduce the house edge and improve your long-term results.

Maximising Your Chances at NZ Online Casinos
While no strategy can guarantee a win at an online casino, understanding the odds and employing smart playing habits can certainly enhance your experience and potentially improve your long-term outcomes:
- Choose Games Wisely: Opt for games with a higher RTP and lower house edge, such as European Roulette over American, or Blackjack with optimal strategy.
- Learn Basic Strategy: For skill-based games like Blackjack and certain poker variants, investing time in learning basic strategy can significantly reduce the house edge.
- Manage Your Bankroll: Set a budget for your gambling activities and stick to it. Never chase losses.
- Play Responsibly: Gambling should always be for entertainment. If you feel you're losing control, seek help. New Zealand offers resources like the Gambling Helpline (0800 654 655) and the Problem Gambling Foundation of New Zealand.
Understanding the odds is a fundamental part of responsible and enjoyable online gambling for New Zealand players. By knowing the RTP and house edge of your favourite games, you can make more informed choices and approach your gaming with a clearer perspective on the inherent probabilities involved. Remember, the casino always has an edge, but playing smart can make a difference.
