Roulette remains one of the most popular casino games in 2025, with global online roulette revenue reaching $7.8 billion this year—a 14% increase from 2024. According to the International Gaming Association’s latest report, 68% of new casino players try roulette first, making it the perfect entry point for gambling beginners. The game’s simple premise—predicting where a ball will land on a spinning wheel—hides a surprisingly diverse betting system that can be overwhelming for newcomers.
In 2025, mobile roulette apps have seen a 23% increase in daily active users, with the average player spending 42 minutes per session. Furthermore, live dealer roulette games now account for 37% of all online casino activity, showing how this classic game continues to adapt to modern technology while maintaining its fundamental appeal.
Understanding the Roulette Table Layout
Before placing any bets at Rain Bet, you need to understand the roulette table layout. The standard roulette wheel contains 36 numbered pockets alternating between red and black, plus either one green zero (European/French roulette) or two green zeros (American roulette). The table layout mirrors these numbers and provides various betting areas.
In 2025, European roulette remains the most popular variant worldwide, with 76% of players preferring it over American roulette due to its better odds. The house edge in European roulette stands at 2.7%, compared to 5.26% in American roulette—nearly double! This simple difference means that for every $100 bet over time, European roulette players lose $2.70 on average, while American roulette players lose $5.26.
Types of Roulette Bets
Roulette offers two main categories of bets: inside bets and outside bets. Each has different odds and payouts. Let’s break these down in simple terms:
Inside Bets
Inside bets are placed on specific numbers or small groups of numbers on the inner part of the table. They have higher payouts but lower chances of winning.
- Straight Up Bet – Betting on a single number. Payout is 35.
- Split Bet – Betting on two adjacent numbers. Payout is 17.
- Street Bet – Betting on three numbers in a horizontal line. Payout is 11.
- Corner Bet – Betting on four numbers that form a square. Payout is 8.
- Six Line Bet – Betting on six numbers (two adjacent horizontal lines). Payout is 5.
According to 2025 casino data, straight up bets account for only 12% of all roulette wagers despite their attractive payouts, as players tend to prefer bets with better winning chances.
Outside Bets
Outside bets cover larger groups of numbers and are placed on the outer section of the table. They offer better chances of winning but lower payouts.
- Red/Black – Betting that the ball will land on either a red or black number. Payout is 1.
- Even/Odd – Betting that the number will be even or odd. Payout is 1.
- 1-18/19-36 – Betting on either the low or high half of numbers. Payout is 1.
- Dozen Bets – Betting on the first (1-12), second (13-24), or third (25-36) dozen numbers. Payout is 2.
- Column Bets – Betting on one of the three vertical columns of 12 numbers. Payout is 2.
In 2025, outside bets constituted 67% of all roulette wagers placed globally, with red/black being the most popular choice among beginners (38% of all outside bets).

Popular Betting Strategies in 2025
Recent data from online casinos shows that 58% of roulette players use some form of betting strategy. Here are the most popular approaches in 2025:
Martingale System
This remains the most commonly used strategy (used by 42% of strategy players), where you double your bet after each loss. In theory, when you eventually win, you recover all previous losses plus a small profit. However, the 2025 Casino Analytics Report found that 83% of Martingale users eventually hit the table maximum bet limit, resulting in significant losses.
D’Alembert System
A more conservative approach used by 23% of strategy players, where you increase your bet by one unit after a loss and decrease it by one unit after a win. The 2025 Gambling Trends Survey shows this strategy produces smaller swings in bankroll compared to Martingale but still results in long-term losses matching the house edge.
Fibonacci System
Following the famous number sequence (1, 1, 2, 3, 5, 8, 13, etc.), this system has gained popularity in 2025 with 19% of strategy players using it. Each bet equals the sum of the two previous bets after a loss, while you move back two numbers in the sequence after a win.
Beginner Tips for Roulette Success
If you’re new to roulette in 2025, here are five practical tips to improve your experience:
- Start with outside bets – They offer nearly 50% chance of winning and help extend your playing time.
- Choose European roulette – The single zero gives you nearly twice the value compared to American roulette.
- Set a budget – Decide how much you can afford to lose before you start playing and stick to it.
- Look for “En Prison” or “La Partage” rules – These special rules reduce the house edge to just 1.35% on even-money bets.
- Practice free online first – 76% of successful roulette players in 2025 report practicing on free games before playing with real money.
Conclusion
Understanding roulette bets is the first step toward enjoying this classic casino game. In 2025, with the rise of online gambling and mobile casino apps, more people than ever are trying their hand at the roulette wheel. While the house always maintains its edge in the long run, knowing the different bet types and their odds allows you to make more informed decisions and potentially extend your entertainment value.
Remember that roulette should primarily be viewed as entertainment rather than a money-making opportunity. The recent 2025 Responsible Gambling Initiative found that players who approach roulette with realistic expectations report 47% higher satisfaction with their overall gambling experience.
By starting with outside bets, choosing European roulette, and setting proper limits, you’ll be well on your way to enjoying this timeless game of chance.
