Roulette is typically easy to pick up and offers plenty of ways to place a bet. With a spinning wheel and a grid of numbers, it’s natural to wonder which choices stand out and how the different options actually work.
This blog post walks through the table layout, how numbers come into play, and introduces two versions of the game that players often encounter. It also covers the different ways to bet—some focused, others broader—so terms like straight up, split, street, corner, red or black, odd or even, and high or low become clearer as you go.
You’ll also find simple explanations for choosing numbers based on recent results, what gives the casino a slight edge, and practical ways to stay organised with your staking throughout a session.

What Is a Roulette Table?
A roulette table has two main parts: the spinning section and the area used for bets. The spinning part holds a series of numbered pockets where the outcome is determined once the ball comes to rest.
On the felt, you’ll see all the available choices for placing a chip. These include single positions, small sets, and larger groupings that extend beyond individual numbers. The design is clear, with each section marked to show what it represents.
If you’re just getting started, a quick look at the layout before placing anything can help you get comfortable and avoid any early mix-ups.
How Do Roulette Numbers Work?
Every wheel is built with a specific range of pockets. European wheels use 37, while another version adds one more. That additional detail is important and we’ll explore it shortly.
Numbers around the wheel aren’t in order but are set in a deliberate pattern. They alternate colours—red and black—except for a few special ones that are green. Once bets are made, the wheel is spun and the ball lands in one of the pockets, deciding the outcome.
Chips on the layout can point to one specific number or to groups, and understanding how these groups form is the key to unlocking all the betting possibilities. But before diving into those, it helps to know exactly how the two most common wheel types compare.
European vs American Roulette: What’s the Difference?
The European version includes numbers 1 to 36, along with a single green zero. The American version has the same set, plus one extra green pocket: the double zero. This is the main difference between the two, and it affects the general structure of outcomes over time.
Because of this, many players consider the version they’re playing before deciding how to approach the layout. It’s worth checking which wheel is in use if you’re thinking about taking part, as the pocket arrangement can subtly influence how the numbers play out across repeated rounds.
Now that the layouts and wheel types are clear, the natural next question is about the numbers themselves—whether any are more worthwhile than others.
What Are the Best Numbers to Bet on in Roulette?
All the numbers around the wheel have the same individual chance of appearing when the ball drops. The layout and design do not favour any one option.
Some players like to pick based on personal meaning—birthdays, anniversaries, or sequences that feel familiar. Others pay attention to patterns that have emerged during recent play, sometimes using them to shape their next choice. These patterns are often referred to by names we’ll introduce in the following section.
There’s no method for forecasting the next outcome, but deciding how you choose numbers can make the experience more enjoyable. Whether you prefer to mix it up or stay consistent, aligning with your own pace and preferences can help you stay engaged without straying from your plan.
Hot Numbers vs Cold Numbers: Do They Matter?
The terms hot and cold refer to how frequently specific numbers have shown up recently. Hot numbers have landed more often, while cold numbers haven’t appeared for a while. Some players track this and use it as a way to shape their approach.
It’s important to keep in mind that each spin stands alone. A number that hasn’t appeared lately is not any more likely to show up next, and one that just hit is no more favoured on the following round. This idea, often misunderstood, leads many to expect patterns where none actually exist.
Still, using recent outcomes to structure your choices can add a sense of direction. Just remember that it doesn’t affect the underlying odds. It’s another way to frame your approach without expecting it to influence results.
Now that the role of numbers is clearer, let’s explore how the layout groups them and what kinds of bets can be placed.
Inside Bets Explained
Inside bets are those placed within the central grid on the layout. These selections point to one number or a tightly grouped section. Because they target fewer outcomes, they don’t come up as frequently—but when they do, the return is greater than on broader options.
This part of the layout includes several bet types with names you might have heard before: straight up, split, street, and corner. Each one covers a different pattern of adjacent numbers.
These bets appeal to those who prefer to focus on a few spots rather than cover wider areas. The trade-off lies in how often they might land versus how much they return when they do.
Straight Up, Split, Street, and Corner Bets
Each of these inside bets has a distinct shape on the felt:
- A straight up bet covers one number, including the zero, by placing a chip right in its box.
- A split bet straddles two numbers next to each other, placed on the dividing line.
- A street covers three numbers in a row, with the chip at the end of that row.
- A corner covers four numbers that meet at one corner point.
These are often used in combination to suit different pacing styles. Choosing which to use and how often depends on how you want your session to unfold. If you’re more interested in covering broader selections, the next part of the layout offers a different approach.
Outside Bets Explained
Outside bets surround the main grid and group numbers in broader sets. Rather than focusing on individual outcomes, these groupings share general traits.
They include red or black, odd or even, and high or low. In addition, there are bets that cover a full column of 12 numbers or a dozen grouped by number order. These don’t pay as much as inside bets, but they appear more regularly, which some players find appealing.
Because the layout clearly labels each section, it’s easy to see which part you’re selecting before a spin. These bets are often where new players start, and they work well as part of a more measured session.
Red or Black, Odd or Even, High or Low
These three are among the most widely recognised bets:
- Red or black covers whether the winning number is from the red or black pockets.
- Odd or even looks at whether the result is an odd or even number.
- High or low splits the numbers into two ranges: 1 to 18 and 19 to 36.
The green zero pockets, and the additional green 00 on the American wheel, fall outside these categories. That difference is part of what gives the casino a mathematical edge, which we’ll now look at more closely.
What Is the House Edge in Roulette?
The casino’s edge comes from the few pockets that don’t fall into any of the usual groupings. These are the green zeros, which aren’t covered by the broader bets like red or black or high or low.
On a European wheel, this edge is created by a single green pocket, making it around 2.70%. On an American wheel, the addition of a second green pocket increases it to around 5.26%. This applies across all bets, even though each option pays out differently.
Understanding this subtle margin helps explain why results tend to lean a certain way over a long series of spins. While individual rounds can vary greatly, this built-in design makes the outcome slightly more favourable to the house across many plays.
How to Manage Your Bankroll When Playing Roulette?
If you choose to play roulette, having a simple plan in place can make the experience feel more structured and easier to enjoy. Before you begin, it helps to decide how much you're comfortable using for that session. Treating this amount as your upper limit can prevent things from escalating if results don't go your way early on.
You might find it beneficial to divide that total into smaller segments, which can help you pace your decisions rather than letting the outcome of just a few rounds shape your whole session. Sticking to a consistent stake size also keeps things steady. If you prefer a bit of variation, you could set a small range—perhaps a regular amount and an occasional higher bet—and stay within that boundary.
Short breaks can make a difference, too. Even just stepping away for a few minutes or keeping an eye on how long you've been playing can help keep the session balanced.
If you reach the limit you set for yourself, it's worth stopping there rather than continuing in the hope of turning things around. Increasing your stakes to recover an outcome rarely leads to the result you're aiming for. Many platforms now offer helpful features, such as deposit limits, time-outs, or reminders, that you can set up before you start.
With a clear understanding of the layout and bet types, you’re in a better position to make the most of each session on your own terms.
If you choose to play, always do so with responsible gambling practices in mind and never wager more than you are willing to lose.
