Rules of Roulette
Roulette is one of the simplest casino games to understand. A wheel with numbered pockets (0–36 in European roulette) is spun by the dealer. A small ball is released in the opposite direction and eventually lands in one of the pockets. Your job is to predict where the ball will land.
Before each spin, you place chips on the betting layout to wager on specific numbers, groups of numbers, or properties like colour and parity. Once the dealer announces "no more bets," the outcome is determined by where the ball settles. Winning bets are paid out according to fixed odds, and losing bets are collected.
Bet Types Explained
Inside Bets
Inside bets are placed directly on individual numbers or small groups of adjacent numbers on the layout. They offer higher payouts but lower odds of winning.
| Bet Type | Description | Payout | Probability (European) |
|---|---|---|---|
| Straight Up | Single number | 35:1 | 2.7% |
| Split | Two adjacent numbers | 17:1 | 5.4% |
| Street | Three numbers in a row | 11:1 | 8.1% |
| Corner | Four numbers that form a square | 8:1 | 10.8% |
| Line (Six Line) | Two adjacent rows (six numbers) | 5:1 | 16.2% |
Outside Bets
Outside bets cover larger groups of numbers. They win more often but pay less.
| Bet Type | Description | Payout | Probability (European) |
|---|---|---|---|
| Red / Black | Bet on the colour | 1:1 | 48.6% |
| Odd / Even | Bet on odd or even numbers | 1:1 | 48.6% |
| High / Low | 1–18 (low) or 19–36 (high) | 1:1 | 48.6% |
| Dozens | 1–12, 13–24, or 25–36 | 2:1 | 32.4% |
| Columns | One of three vertical columns of 12 numbers | 2:1 | 32.4% |
European vs American vs French Roulette
The roulette variant you choose has a direct impact on your odds. Here is how the three main versions compare:
| Feature | European | American | French |
|---|---|---|---|
| Pockets | 37 (0–36) | 38 (0, 00–36) | 37 (0–36) |
| Zero Pockets | Single zero (0) | Zero (0) and double zero (00) | Single zero (0) |
| House Edge | 2.70% | 5.26% | 1.35% (on even-money bets) |
| La Partage Rule | No | No | Yes — half your even-money bet returned if ball lands on 0 |
| En Prison Rule | Rarely | No | Yes — your even-money bet stays for the next spin if ball lands on 0 |
| Recommended? | Yes — good default | No — worst odds | Yes — best odds on even bets |
Popular Roulette Strategies — Honest Assessment
No roulette strategy can overcome the house edge in the long run. The ball has no memory, and every spin is independent. That said, strategies can help you structure your betting and manage your bankroll. Here is an honest look at the most popular ones:
Martingale
How it works: Double your bet after every loss. When you win, you recover all previous losses plus a profit equal to your original stake.
Pros
- Simple to understand and follow
- Works well in short sessions
- Frequent small wins
Cons
- Bets escalate rapidly after a losing streak
- Table limits cap how many times you can double
- A long losing streak can wipe out your entire bankroll
- Does not change the house edge
Verdict: High risk. The Martingale can feel effective in the short term, but the mathematics work against you. A run of 7–8 consecutive losses (which happens more often than people think) can be devastating.
D'Alembert
How it works: Increase your bet by one unit after a loss; decrease by one unit after a win. A gentler progression than Martingale.
Pros
- Lower risk than Martingale
- Bets increase gradually
- Easier to manage bankroll
Cons
- Slower recovery after losing streaks
- Still does not overcome the house edge
- Requires roughly equal wins and losses to profit
Verdict: Moderate risk. Safer than Martingale but still no guarantee of profit. Best suited to players who want a structured approach without extreme bet escalation.
Fibonacci
How it works: Follow the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21...) for bet sizing. Move one step forward after a loss, two steps back after a win.
Pros
- More gradual progression than Martingale
- Can recover losses without needing consecutive wins
- Mathematically elegant approach
Cons
- Extended losing streaks still create large bets
- Complex to track during play
- Does not change the fundamental odds
Verdict: Moderate risk. A reasonable middle ground. The progression is slower, but the core problem remains — no betting pattern can turn a negative expectation game into a positive one.
Live Roulette Options
Live roulette has transformed online play, bringing the atmosphere of a real casino directly to Irish players' screens. Here are the most popular live roulette formats:
Lightning Roulette
Developed by Evolution, Lightning Roulette adds random multipliers of up to 500x to straight-up bets on each round. One to five lucky numbers are struck by lightning before the spin, and if you have bet on one of them, your payout is multiplied. Standard straight-up bets pay 29:1 instead of the usual 35:1 to fund the multipliers, so the house edge is slightly higher at around 2.7%.
Immersive Roulette
Another Evolution title, Immersive Roulette uses multiple HD cameras and slow-motion replays to create a cinematic experience. The rules are identical to standard European roulette — the innovation is purely in presentation. It is ideal for players who want the most visually engaging live roulette experience.
Other Live Variants
- Speed Roulette — Rounds completed in 25 seconds for fast-paced play.
- Auto Roulette — No human dealer; the wheel spins automatically. Lower stakes available.
- Dual Play Roulette — Streamed from a real land-based casino, so you play alongside in-person gamblers.
- XXXtreme Lightning Roulette — Even higher multipliers (up to 2,000x) with a higher house edge.
Tips for Playing Roulette Online
- Always play European or French roulette — Never choose American roulette when a European or French table is available. The difference in house edge is substantial.
- Start with outside bets — Red/black, odd/even, and high/low give you the closest thing to a coin flip at the table.
- Set strict loss limits — Decide your budget before playing and stick to it. Roulette is fast-paced, and losses can accumulate quickly.
- Do not chase losses — If you hit your limit, stop. The next spin is not "due" to go your way — every spin is independent.
- Try the demo first — Many RNG roulette games offer free play. Use this to familiarise yourself with the betting layout before wagering real money.
- Combine inside and outside bets — Experienced players often place a few straight-up bets alongside larger outside bets for a balance of risk and reward.
- Watch for French roulette with La Partage — If available, this halves the house edge on even-money bets to 1.35%, making it the best-value roulette game you can play.

Frequently Asked Questions
No, not at licensed casinos. Reputable online casinos use Random Number Generators (RNGs) that are tested and certified by independent auditors like eCOGRA and iTech Labs. Live roulette uses a physical wheel streamed in real time, providing complete transparency. Always play at a licensed casino to ensure fair play.
Outside bets such as Red/Black, Odd/Even, or High/Low are ideal for beginners. They pay 1:1 and win close to half the time (48.6% in European roulette). These bets allow you to play longer sessions and get comfortable with the game before trying riskier inside bets.
No. Every roulette strategy is a way to structure your betting, not a way to eliminate the house edge. The Martingale, D'Alembert, and Fibonacci systems can help manage your bankroll, but none changes the mathematical odds of the game. Every spin is independent, and the house always has an edge.
French roulette is better for even-money bets thanks to the La Partage rule, which returns half your bet if the ball lands on zero. This reduces the house edge from 2.70% to just 1.35% on Red/Black, Odd/Even, and High/Low bets. For all other bet types, European and French roulette are identical.
Lightning Roulette is a live casino game by Evolution that adds random multipliers (50x to 500x) to straight-up number bets on each round. It plays like standard European roulette with an added element of excitement. The trade-off is that non-multiplied straight-up bets pay 29:1 instead of the usual 35:1, keeping the house edge at around 2.7%.
