What Are Roulette Hot and Cold Numbers?
Walk into any casino or log into an online game, and you’ll often see a digital board displaying the last 10, 20, or even 50 winning numbers. This feature is the fuel for one of the most popular, yet misunderstood, concepts in roulette: hot and cold numbers.
The Theory Behind “Hot Numbers”
The idea is simple and alluring. “Hot numbers” are numbers that have appeared more frequently than statistically expected in a recent series of spins. Players who follow this theory believe these numbers are on a lucky streak and are more likely to appear again. Conversely, “cold numbers” are those that haven’t shown up for a while. Some players bet on these, believing they are “due” for a hit.
Online casinos and live dealer games actively promote this by displaying these statistics, which encourages players to look for patterns in the randomness.
The Hard Truth: Probability and the Gambler’s Fallacy
Here’s the crucial point every roulette player must understand: every spin of the roulette wheel is an independent event. The wheel, and the ball, have no memory. The outcome of the last spin has absolutely zero influence on the outcome of the next one.
This leads us to a famous logical error known as the Gambler’s Fallacy. This is the mistaken belief that if something happens more frequently than normal in a given period, it will happen less frequently in the future (or vice versa). For example, if the ball lands on red five times in a row, a player might think black is “due” to hit next. In reality, the probability remains the same.
On every single spin, the probability of any specific number hitting is always:
- 1 in 37 for European and French Roulette.
- 1 in 38 for American Roulette.
Conclusion: While tracking hot and cold numbers can be a fun ritual, it is not a mathematically sound strategy for predicting future outcomes. It’s a superstition, not a system.
How to Play a Round of Roulette
New to the wheel? No problem. Playing roulette is straightforward and exciting. Here’s a step-by-step guide for your first round.
- Find a Table: First, choose your preferred game: American, European, or French. Online, this means selecting a game from the casino’s virtual lobby. We always recommend European or French for their better odds.
- Buy Your Chips: In a land-based casino, place your cash on the table and the dealer will exchange it for chips. When playing online, your account balance is used to place bets directly.
- Place Your Bets: Position your chips on the betting layout. You can bet on single numbers, groups of numbers, colors, or other propositions. You must place your bets before the croupier spins the wheel and calls out, “no more bets.”
- The Spin: The croupier spins the wheel in one direction and the ball in the opposite. In online RNG (Random Number Generator) games, the outcome is determined instantly by a certified algorithm to ensure fairness.
- The Result: The ball will eventually lose momentum and land in one of the numbered pockets. The dealer places a marker (a dolly) on the winning number on the layout.
- Payouts: The dealer clears all losing bets from the table and then pays out all the winning bets. Once payouts are complete, the next round begins.
Roulette Betting Options Explained
The roulette table can look intimidating, but the bets are divided into two simple categories: Inside Bets (bets on specific numbers) and Outside Bets (bets on larger groups).
| Bet Type | Location / Description | Payout |
|---|---|---|
| Inside Bets | ||
| Straight Up | A bet on a single number. | 35:1 |
| Split | On the line between two adjacent numbers. | 17:1 |
| Street | On the line at the end of a row of three numbers. | 11:1 |
| Corner (Square) | At the intersection of four numbers. | 8:1 |
| Six Line (Double Street) | On the line between two streets. | 5:1 |
| Outside Bets | ||
| Red / Black | A bet on the color of the winning number. | 1:1 |
| Odd / Even | A bet on whether the number will be odd or even. | 1:1 |
| High / Low (1-18 / 19-36) | A bet on whether the number is high or low. | 1:1 |
| Dozens | A bet on one of three dozens (1-12, 13-24, 25-36). | 2:1 |
| Columns | A bet on one of the three vertical columns. | 2:1 |
Popular Roulette Strategies (Beyond Hot Numbers)
While no strategy can beat the house edge, betting systems can help manage your bankroll and add structure to your play. Here are a few popular ones, along with their risks.
- The Martingale System: The most famous (and infamous) system. You double your bet after every loss. When you eventually win, you recover all previous losses plus a profit equal to your original stake. Risk: Extremely dangerous. A short losing streak can cause your bets to grow exponentially, quickly hitting the table limit or wiping out your bankroll.
- The Fibonacci System: A negative progression system where you increase your bet after a loss according to the Fibonacci sequence (1, 1, 2, 3, 5, 8…). After a win, you move back two numbers in the sequence. Risk: Safer than Martingale as bets increase more slowly, but a long losing streak can still lead to significant losses.
- The D’Alembert System: A much flatter and safer system. You increase your bet by one unit after a loss and decrease it by one unit after a win. Risk: Much lower risk, but your wins will be modest. It requires an equal number of wins and losses to break even.
- The 3/2 System: This is a coverage strategy. The goal is to cover over 70% of the wheel. An example is placing 3 units on Red and 2 units on the second column. This covers most red numbers and many black numbers. Risk: You get smaller, more frequent wins, but when you lose, the loss is larger (5 units).
- The $150 Strategy: Another popular coverage strategy. A common example is to bet $100 on the High numbers (19-36), $40 on a specific six-line (e.g., 13-18), and $10 on the zero for insurance. Risk: This strategy covers 25/37 numbers, giving a high chance of a win, but a single loss costs the full $150 stake.
Roulette Odds and Payouts: A Comparison
The house edge in roulette comes from the difference between the true odds of hitting a number and the payout offered by the casino. The green zero (and double zero) pocket is what tips the odds in the house’s favor.
| Bet Type | European Wheel Probability | American Wheel Probability | Payout |
|---|---|---|---|
| Straight Up | 2.70% (1 in 37) | 2.63% (1 in 38) | 35:1 |
| Split | 5.41% (2 in 37) | 5.26% (2 in 38) | 17:1 |
| Column/Dozen | 32.43% (12 in 37) | 31.58% (12 in 38) | 2:1 |
| Even Money Bets | 48.65% (18 in 37) | 47.37% (18 in 38) | 1:1 |
Popular Roulette Game Variations
The classic game of roulette has evolved, especially in the online world. Here are the key variations you’ll find in 2025.
European Roulette
This is the gold standard and the most player-friendly version. It features a wheel with 37 pockets (1-36 and a single zero). The house edge is a favorable 2.7%.
American Roulette
The main difference in this version is an additional pocket: the double zero (00). While it may seem like a small change, this extra pocket nearly doubles the house edge to 5.26%. For this reason, we recommend avoiding it if a European version is available.
French Roulette
Visually similar to European Roulette, this variant includes special rules that benefit the player. “La Partage” returns half of your even-money stake if the ball lands on zero. “En Prison” holds your bet for another spin. These rules slash the house edge on even-money bets to an incredibly low 1.35%.
Live Dealer Roulette
The perfect blend of online convenience and real-casino atmosphere. Live dealer games are streamed in HD from a studio with a real human croupier spinning a physical wheel. It’s the most immersive way to play online, with top providers like Evolution Gaming and Pragmatic Play leading the market.
Modern Variations
Online casinos have introduced exciting new twists on the classic game. Titles like Lightning Roulette add random multipliers of up to 500x to straight-up bets on each round. Other games like Multi-Wheel Roulette allow you to bet on the outcome of up to eight wheels at once.
Common Mistakes to Avoid
Steer clear of these common pitfalls to protect your bankroll and enhance your enjoyment of the game.
- Believing in the Gambler’s Fallacy: The most common mistake. Never think a number is “due” to hit because it hasn’t appeared recently.
- Playing American Roulette: Always choose European or French roulette when you have the option. Your odds are significantly better.
- Chasing Losses: Trying to win back lost money by making larger, riskier bets is the fastest way to empty your account. Stick to your plan.
- Ignoring Bankroll Management: Playing without a clear budget and limits is a recipe for disaster. Know when to stop.
- Relying Solely on Betting Systems: Remember that no system can overcome the house edge. They are tools for managing your play session, not for guaranteeing wins.
Essential Bankroll Management Tips
Responsible gaming starts with smart money management. Follow these tips to stay in control.
- Set a Strict Budget: Before you play, decide on a specific amount of money you are willing to risk and can comfortably afford to lose. Treat it as an entertainment expense.
- Establish Win/Loss Limits: Have a clear goal. Decide in advance that you will walk away if you lose a certain amount (a stop-loss) or if you win a certain amount (a win-goal).
- Define Your Betting Unit: A good rule of thumb is to make your standard bet size between 1% and 2% of your total session bankroll. This prevents you from losing everything too quickly.
- Never Borrow Money to Gamble: Gambling should never be seen as a way to make money or solve financial problems. Only use your own disposable income.
Frequently Asked Questions About Roulette Hot Numbers
What number hits most in roulette?
Over a short session, any number can appear to hit most often due to random variance. However, in any fair and properly functioning roulette game, all numbers have an exactly equal probability of being hit on any given spin. Over thousands or millions of spins, the results will even out, and all numbers will have appeared a similar number of times.
What is the $150 roulette strategy?
This is a high-coverage betting strategy designed to achieve frequent, small wins. A common version involves making three separate bets: $100 on the high numbers (19-36), $40 on a six-line bet (like 13-18), and $10 on the zero. This covers 25 of the 37 numbers on a European wheel. While the win rate is high, a single loss costs the entire $150 stake.
How to predict numbers in roulette?
It is statistically and physically impossible to predict the winning number in a legitimate game of roulette. Online games use certified Random Number Generators (RNGs) to ensure every outcome is random and independent. In a physical casino, the result is determined by complex physics. Strategies are for managing money, not for predicting outcomes.
What is the 3-2 rule in roulette?
The 3-2 system is another coverage strategy. A player places a 3-unit bet on a color (e.g., Red) and a 2-unit bet on a column. The ideal approach is to bet on a column that has more of the opposite color’s pockets. For example, the third column has 8 red pockets and 4 black ones. So, a player might bet 3 units on Black and 2 units on the third column to cover around 70% of the numbers on the wheel.
Responsible Gambling Reminder: Roulette is a game of chance and should be played for entertainment purposes only. The house always has a mathematical edge. Please play responsibly, set limits, and never gamble more than you can afford to lose. If you feel you may have a gambling problem, seek help from professional organizations.
