Whether you have never played before or want to sharpen your game, this is your starting point. |
| Part 1 — The history of roulette |
Where roulette came from
Roulette is one of the oldest and most recognized casino games in the world. Its name comes from the French word meaning “little wheel”, and its origins trace back to 18th century France. The game is widely believed to have evolved from earlier wheel-based games popular in Europe, combined with elements of English wheel games like Roly-Poly and even-odd.
The version closest to the modern game is attributed to French mathematician and physicist Blaise Pascal, who is said to have stumbled upon the basic concept while attempting to design a perpetual motion machine in the 17th century. While his machine did not achieve perpetual motion, the spinning wheel it inspired eventually found its way onto the casino floor.
By the late 1700s, a version of roulette with both a single zero and double zero pocket was already being played in Paris. The single-zero version — which gives the house a lower edge — was introduced in 1843 by François and Louis Blanc in Hamburg, Germany, to attract players away from rival casinos. This became the standard European game. When gambling was banned in Germany, the Blancs moved their operation to Monte Carlo, cementing roulette’s association with glamour and high society.
The double-zero version of the game travelled to the United States with European immigrants and became the standard there — which is why the two main variants are known today as European and American roulette. The extra double-zero pocket increases the house edge significantly, which is why most experienced players prefer the European version wherever it is available.
Today, roulette is played in casinos on every continent. It remains one of the most popular table games worldwide and is a fixture in virtually every casino in Trinidad & Tobago.
| Part 2 — How roulette works |
The basics of the game
Roulette is a game of chance. Players place bets on where a small ball will land on a spinning wheel divided into numbered pockets. The wheel is spun by the dealer — also called the croupier — and the ball is dropped into the wheel travelling in the opposite direction. When the ball settles into a pocket, the winning number is announced and all winning bets are paid out.
There is no skill involved in predicting where the ball will land. Each spin is completely independent of the last. The appeal of roulette lies in its simplicity, its range of betting options, and the tension of watching the ball find its pocket.
The wheel
A European roulette wheel has 37 pockets numbered 0 through 36. An American roulette wheel has 38 pockets — numbered 0 through 36 plus an additional 00 (double zero) pocket. The numbers are not arranged in sequential order on the wheel. The layout is designed so that high and low numbers alternate as much as possible, and red and black pockets alternate throughout, with the green zero pocket separating sequences.
The European wheel sequence clockwise is: 0, 32, 15, 19, 4, 21, 2, 25, 17, 34, 6, 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 35, 3, 26.
The table layout
The roulette table is divided into two main areas: the inside betting area and the outside betting area. The inside area shows a grid of all the numbers 0 to 36 (and 00 on American tables). The outside area contains boxes for broader bets like red or black, odd or even, and number ranges.
Players place their chips directly on the table layout before the dealer spins the wheel. Most tables allow multiple players to bet simultaneously, with each player using a different colour chip so bets can be distinguished.
How a round plays out
A standard round of roulette follows this sequence:
- The dealer opens betting. Players place chips on the table in their chosen positions.
- The dealer spins the wheel and drops the ball in the opposite direction.
- As the ball slows, the dealer calls “no more bets”. No further chips may be placed.
- The ball settles into a pocket. The dealer announces the winning number and marks it on the table with a dolly (a marker).
- Losing bets are cleared from the table. Winning bets are paid out.
- The dolly is removed. The next round of betting begins.
| Do not place or touch chips on the table while the dolly is down. This is one of the most important rules of roulette etiquette. Wait until the dealer removes the marker and invites betting before placing your chips. |
| Part 3 — Every type of bet explained |
Inside bets
Inside bets are placed on specific numbers or small groups of numbers within the numbered grid on the table. They carry higher payouts but lower odds of winning.
| Bet type | What you are betting on | Payout | Probability (Euro) |
| Straight up | A single number. Place your chip directly on one number. | 35 to 1 | 2.70% |
| Split | Two adjacent numbers. Place your chip on the line between them. | 17 to 1 | 5.41% |
| Street | Three numbers in a horizontal row. Chip on the outer edge of the row. | 11 to 1 | 8.11% |
| Corner (square) | Four numbers forming a square. Chip on the corner where all four meet. | 8 to 1 | 10.81% |
| Six line | Two adjacent rows of three numbers (six numbers total). Chip on the outer corner between the two rows. | 5 to 1 | 16.22% |
| Trio | Zero, 1, and 2 — or 0, 2, and 3. European only. Chip on the intersection. | 11 to 1 | 8.11% |
| Basket (first four) | 0, 1, 2, and 3. European only. Chip at the corner of 0 and 1. | 8 to 1 | 10.81% |
| Five number | 0, 00, 1, 2, and 3. American roulette only. Worst bet on the table. | 6 to 1 | 13.16% |
Outside bets
Outside bets are placed in the boxes surrounding the number grid. They cover larger groups of numbers and pay out less but win more often. They are the most popular bets for beginners and casual players.
| Bet type | What you are betting on | Payout | Probability (Euro) |
| Red / Black | The colour of the winning number. 18 red or 18 black numbers. | 1 to 1 | 48.65% |
| Odd / Even | Whether the winning number is odd or even. Zero loses. | 1 to 1 | 48.65% |
| Low / High | Low covers 1–18. High covers 19–36. Zero loses on both. | 1 to 1 | 48.65% |
| Dozens | First dozen (1–12), second dozen (13–24), or third dozen (25–36). | 2 to 1 | 32.43% |
| Columns | One of three vertical columns of 12 numbers each. Zero is not included. | 2 to 1 | 32.43% |
| Outside bets that pay even money (1 to 1) do not cover the zero. When the ball lands on zero, all even-money outside bets lose — this is where the house gets its edge. Some casinos offer the La Partage or En Prison rules that partially protect even-money bets when zero hits. See Part 5 for details. |
Called bets and announced bets
Called bets — also known as French bets or announced bets — are special wagers that cover specific sections of the wheel rather than sections of the table layout. They are more common in European casinos and high-limit rooms and are placed verbally with the dealer or on a special oval track called the racetrack.
Voisins du zéro — Neighbours of zero
Covers the 17 numbers closest to zero on the European wheel: 22, 18, 29, 7, 28, 12, 35, 3, 26, 0, 32, 15, 19, 4, 21, 2, 25. Requires 9 chips. It is the largest of the called bets.
Tiers du cylindre — Third of the wheel
Covers 12 numbers on the opposite side of the wheel from zero: 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33. Requires 6 chips placed as split bets.
Orphelins — Orphans
Covers 8 numbers not included in voisins or tiers: 17, 34, 6 on one side and 1, 20, 14, 31, 9 on the other. Requires 5 chips.
Jeu zéro — Zero game
Covers the 7 numbers closest to zero: 12, 35, 3, 26, 0, 32, 15. Requires 4 chips. A simplified version of voisins du zéro.
Neighbours
A bet on any number and the two numbers on either side of it on the wheel — five numbers in total. For example, “17 and the neighbours” covers 25, 17, 34, 6, and the numbers adjacent. You can request any number of neighbours. Requires 5 chips.
| Called bets are a great way to bet on specific sections of the wheel rather than the table layout. If you have a feeling the ball is landing in a particular zone of the wheel, a called bet lets you act on it efficiently. Ask your dealer if called bets are available at your table. |
| Part 4 — European vs American roulette |
Choosing the right version
The most important decision you can make at the roulette table happens before you place a single chip — choosing which version of the game to play. European and American roulette look almost identical but have one crucial difference that significantly affects your chances.
| Feature | European roulette | American roulette |
| Number of pockets | 37 (0–36) | 38 (0–36 + 00) |
| Zero pockets | Single zero only | Zero and double zero |
| House edge | 2.70% | 5.26% |
| Straight up win probability | 2.70% | 2.63% |
| Even money win probability | 48.65% | 47.37% |
| La Partage / En Prison rules | Available at some tables | Not available |
| Called / French bets | Standard | Rare |
| Best choice for players? | Yes | No — avoid if European available |
Why the house edge matters
The house edge is the mathematical advantage the casino holds over players in the long run. On European roulette the house edge is 2.70%, meaning for every $100 wagered over time, the casino expects to keep $2.70. On American roulette, the double-zero pocket pushes the house edge to 5.26% — nearly double.
Over a short session this difference may not be noticeable. But over dozens or hundreds of spins, it compounds significantly. A player making $20 bets over 100 spins is wagering $2,000 in total. The expected loss on European roulette is $54. On American roulette it is $105. The double zero costs you almost twice as much for an identical session.
| If your casino offers both versions, always choose European roulette. The single-zero wheel gives you better odds on every single bet. There is no scenario where playing American roulette is the better choice for the player. |
French roulette
French roulette uses the same single-zero wheel as European roulette but includes two additional rules — La Partage and En Prison — that reduce the house edge on even-money bets to just 1.35%. It is the best version of roulette for the player and is worth seeking out if it is available.
| Part 5 — Special rules |
La Partage and En Prison
These two rules apply to even-money outside bets (red/black, odd/even, high/low) and only come into effect when the ball lands on zero. They are found primarily on French roulette tables and some European roulette tables in higher-end casinos.
La Partage — “the sharing”
When the ball lands on zero, all even-money outside bets lose half their stake rather than the full amount. Your remaining half is returned to you. This simple rule cuts the house edge on even-money bets from 2.70% to 1.35%, making it one of the most player-friendly rules in any casino game.
Example: You bet $40 on red. The ball lands on zero. Under La Partage, $20 is returned to you and $20 goes to the casino.
En Prison — “in prison”
When the ball lands on zero, your even-money bet is “imprisoned” rather than lost. It stays on the table for the next spin. If your bet wins on the next spin, your original stake is returned in full — you do not receive winnings, just your money back. If it loses, the casino keeps it.
En Prison gives you a second chance when zero hits. The mathematical effect on the house edge is the same as La Partage — 1.35% on even-money bets. Some players prefer En Prison because there is a chance to fully recover the stake rather than automatically losing half.
| If you are playing on a table with La Partage or En Prison rules, your focus should be on even-money outside bets. At 1.35% house edge, these are among the best wagers available at any casino table. |
| Part 6 — Betting strategies |
Do betting strategies work?
This is one of the most common questions in roulette. The honest answer is that no betting strategy can overcome the house edge in the long run. Roulette is a game of independent events — each spin has no memory of the last. A number that has not appeared in 20 spins is not “due” to come up. The odds reset completely on every spin.
What betting strategies can do is structure how you play, manage your bankroll, determine how long your money lasts, and in some cases increase your chances of leaving the session ahead — at the cost of risking larger losses when things go wrong. Understanding each strategy and its trade-offs helps you choose one that fits your goals and temperament.
The Martingale
The most widely known roulette strategy. You start with a base bet on an even-money outside bet. Every time you lose, you double your bet. When you win, you return to your base bet. The idea is that a single win recovers all previous losses and nets you a profit equal to your base bet.
Example with a $10 base bet:
- Spin 1: Bet $10 — lose. Total lost: $10
- Spin 2: Bet $20 — lose. Total lost: $30
- Spin 3: Bet $40 — lose. Total lost: $70
- Spin 4: Bet $80 — win. Win $80. Net result: +$10
The problem: a losing streak sends bets escalating rapidly. After just 7 consecutive losses from a $10 base, your next required bet is $1,280. Most tables have a maximum bet limit that will stop the progression before you can recover your losses. A run of 8 or 9 consecutive losses — which is not unusual in the short term — can wipe out an entire session bankroll.
| The Martingale is the most dangerous strategy for bankroll management. It feels safe because small wins happen regularly, but a single bad run can result in catastrophic losses very quickly. Set a hard stop-loss before you start and stick to it. |
The Reverse Martingale (Paroli)
The opposite of the Martingale. You double your bet after each win rather than each loss, and return to your base bet after a loss or after three consecutive wins. The strategy aims to capitalise on winning streaks while limiting losses to your base bet.
The Paroli is considered lower risk than the Martingale because you are wagering winnings rather than digging deeper into your bankroll. Losses are capped at one base bet. The downside is that you need a winning streak to generate significant profit.
The D’Alembert
A gentler progression than the Martingale. After each loss, increase your bet by one unit. After each win, decrease your bet by one unit. The idea is that wins and losses will eventually balance out and you will profit by one unit for each win that follows a loss.
The D’Alembert is slower and less volatile than the Martingale, making it more suitable for players who want a structured approach without extreme swings. It does not overcome the house edge, but it provides a more measured way to manage your session.
The Fibonacci
Based on the famous mathematical sequence in which each number is the sum of the two before it: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 … You move one step forward in the sequence after each loss and two steps back after each win.
The Fibonacci progresses more slowly than the Martingale and requires a smaller maximum bet to recover losses. It is more complex to track mid-session and still carries the risk of a long losing run outpacing your bankroll.
The James Bond
A fixed flat-bet strategy that covers more than half the wheel on every spin. With a $200 total stake each round: place $140 on the high numbers (19–36), $50 on the six-line covering 13 to 18, and $10 on zero.
This covers 25 of the 37 numbers on a European wheel. If a number between 1 and 12 hits, you lose the full $200. The strategy generates small, regular wins on most spins but is vulnerable to the uncovered 12 numbers. It is best suited to short sessions where you want a structured way to cover most outcomes.
Flat betting
The simplest approach. Bet the same amount on every spin regardless of outcomes. Flat betting does not chase losses, does not escalate risk, and is the most sustainable way to play over a longer session. While it will not generate the short-term excitement of a progression system, it gives you the clearest picture of your actual results and keeps your bankroll in your control.
| For most players, flat betting on even-money outside bets on a European table is the most sensible approach. It minimises variance, makes your bankroll last longer, and keeps the experience enjoyable without the anxiety of escalating bets. |
The gambler’s fallacy
The gambler’s fallacy is the mistaken belief that past results influence future outcomes in an independent game. In roulette, each spin is a fresh event with no connection to what came before. If red has appeared 10 times in a row, the probability of red on the next spin is still 48.65% — exactly the same as it always is. There is no such thing as a number or colour being “due”.
Casinos display spin history boards at roulette tables specifically because players are drawn to patterns. The history board is entertainment, not useful data. Do not make betting decisions based on past results.
| Part 7 — Managing your bankroll |
Playing within your means
Bankroll management is not a strategy for winning — it is a strategy for playing longer, enjoying yourself more, and protecting yourself from losing more than you can afford. Roulette is entertainment. Treat your session budget as the cost of that entertainment, not as an investment.
Setting your session budget
Before you sit down at any roulette table, decide the maximum amount you are willing to lose in that session. Once that amount is gone, you leave. Do not top up from another budget, an ATM, or money set aside for other things. This is the most important rule in responsible gambling.
A useful rule of thumb: bring at least 50 times your minimum intended bet to the table. If you want to bet $10 a spin, bring $500. This gives you enough runway to weather a run of losses without being wiped out on your first bad sequence.
Choosing the right table
Always look for a table whose minimum bet is comfortable relative to your bankroll. If a table’s minimum is $50 and you have $200, four consecutive losses ends your session immediately. Lower-minimum tables give you more spins, more time, and a better overall experience.
Knowing when to stop
- Set a win target before you start. If you reach it, seriously consider leaving. Most players who stay after hitting a good run give back everything they have won.
- Set a loss limit before you start. When you hit it, stop. Do not rationalise “just one more spin”.
- Take breaks. Long continuous sessions lead to tired, careless decisions. Step away, have a drink, reset.
- Never chase losses. Increasing your bets to recover what you have lost is the fastest route to losing significantly more.
| Gambling should always be affordable and enjoyable. If you find yourself betting money you cannot afford to lose, chasing losses, or feeling distressed at the table, please speak to casino staff or contact the National Council on Substance Abuse (NCSA) in Trinidad & Tobago. |
| Part 8 — Table etiquette & casino conduct |
How to conduct yourself at the roulette table
Roulette is a social game and the table has its own set of customs that make the game run smoothly for everyone. Most of these are common sense, but knowing them before you sit down avoids embarrassing moments and keeps you in good standing with the dealer and other players.
Buying in
When you approach a roulette table, wait for a natural pause between spins to sit down. Place your cash on the table — do not hand it directly to the dealer. Tell the dealer how much you are changing and for which denomination of chips. You will be given roulette chips in a specific colour that is assigned to you alone at that table. These chips have no value at other tables — exchange them back for casino chips before you leave.
Placing bets
- Place your chips yourself wherever possible. On busy tables, if you cannot reach a section, you may ask the dealer to place a bet for you — tell them clearly where.
- Do not place bets after the dealer calls “no more bets”. Doing so is a serious breach of etiquette and will result in your late bet being removed.
- Do not touch the dolly — the marker placed on the winning number — or any chips on the table while it is in place. Wait until it is removed.
- You may bet on as many positions as you like on each spin.
Interacting with the dealer
- Be polite and patient. The dealer manages the entire table and is responsible for the integrity of the game.
- If you are unsure where to place a bet or want to make a called bet, ask the dealer. They are there to help.
- Tipping the dealer is customary and appreciated. You can tip by placing a chip on the table for the dealer or by making a bet on their behalf.
- Do not blame the dealer for your losses. They do not influence the outcome of the game.
General conduct
- Keep your phone use to a minimum at the table. Some casinos prohibit photography at the table entirely.
- Keep drinks away from the layout to avoid spills on chips.
- Be aware of other players’ space. Roulette tables can get crowded — be considerate.
- Do not give unsolicited advice to other players about their bets. What they choose to wager is their own business.
- If you are unsure of a rule, ask the dealer before the spin — not after.
| Part 9 — Practical tips for the table |
Making the most of your roulette session
Before you sit down
- Always choose European roulette over American roulette if both are available. The difference in house edge is significant.
- Check whether the table has La Partage or En Prison rules. If it does, prioritise even-money outside bets.
- Know your session budget before you sit down and commit to it.
- Check the table minimum and maximum. Make sure the minimum is comfortable for your bankroll.
At the table
- Start with outside bets if you are new to the game. Red/black and odd/even are the simplest and have the best odds.
- If you want more excitement without high risk, the dozens or columns bets offer a 2 to 1 payout with a reasonable probability.
- Straight-up single number bets carry the highest payout (35 to 1) but the lowest probability. Keep them to a small portion of your total bet if you enjoy them.
- Avoid the five-number bet (0, 00, 1, 2, 3) in American roulette. It carries the highest house edge of any bet on the table at 7.89%.
- Do not increase your bets when you are losing in an attempt to recover quickly. This is how sessions end badly.
- Walk away when you hit your win target or your loss limit — whichever comes first.
Understanding variance
Even with a 48.65% chance of winning an even-money bet, you can lose many spins in a row. This is normal variance and does not mean the game is unfair or that a win is imminent. Roulette sessions can swing dramatically in the short term. The house edge only becomes statistically reliable over thousands of spins — your evening at the casino is a small sample.
Short sessions with a clear budget and a disciplined exit strategy give you the best chance of leaving with a positive experience — whether or not you finish ahead.
