Roulette Bets Explained: A Practical Guide to Inside and Outside Wagers at 9BET
Roulette looks deceptively simple—place a chip on a number, watch the wheel spin, and hope. But walk up to a real table or open a digital client, and you are immediately confronted with a felt covered in numbers, empty boxes, and angled lines. Most new players freeze right there. After years of watching friends and readers make the same mistakes, I can break roulette betting into three key findings that will make your first sessions far less confusing:
- There are only two families of bets: inside bets on specific numbers or small groups, and outside bets on larger categories like red/black or odd/even. Once you see that division, the layout stops looking random.
- Outside bets are not “beginner bets” in the insulting sense. They are lower-risk wagers that pay smaller returns, but they are also used by experienced players to manage bankrolls during cold streaks.
- The rules change slightly by wheel type. The basics of betting are identical, but the odds and house edge differ between European (one zero) and American (two zeros) roulette. Checking your chosen game type matters as much as knowing the bets themselves.
This guide is written from the perspective of someone who has sat at both physical and online tables, taught friends the ropes, and still occasionally re-reads the betting layout before placing a complex wager. It is not a strategy for guaranteed profit—no such thing exists. It is a clear explanation of what each bet means, how much it pays, and how to apply that knowledge in a real game.
Roulette Bets Demystified: Understanding the Two Main Families
Before any spin, you need to understand the geography of the betting table. The table is divided into two zones, and each zone corresponds to a different kind of risk and reward.
Inside bets occupy the numbered grid in the center of the table. These are wagers on specific numbers, adjacent pairs, rows, or small blocks of numbers. They promise the highest payouts because the chance of winning is lower. A straight-up bet on a single number, for instance, is the classic high-risk bet that carries a 35:1 payout.
Outside bets occupy the wider boxes around the numbered grid. These cover larger groups of numbers—like all red numbers, all odd numbers, or the first dozen. They win more frequently than inside bets, but their payouts are correspondingly smaller, usually 1:1 or 2:1.
This distinction is not just cosmetic. The layout dictates the maximum and minimum bet sizes at many tables, and online platforms often group statistics by inside versus outside betting. More importantly, your bankroll behavior changes based on which family you choose. If you prefer long sessions with less volatility, outside bets suit you. If you want bigger swings and occasional large wins, inside bets are the route.

Learning roulette bets is not about memorizing every payout by heart immediately, but you should know the common ones before you place a wager. I have compiled the standard options below. Remember that payouts are fixed on most tables, but the actual odds vary slightly based on the wheel type.
| Bet Type | What It Covers | Payout | Difficulty for New Players |
|---|---|---|---|
| Straight Up | A single number | 35:1 | Easy to understand, hard to win |
| Split | Two adjacent numbers | 17:1 | Low difficulty once you see the line |
| Street | Three numbers in a row | 11:1 | Moderate |
| Corner | Four numbers meeting at a corner | 8:1 | Moderate |
| Outside – Red/Black | Every red or every black number | 1:1 | Very easy |
| Outside – Odd/Even | Every odd or every even number | 1:1 | Very easy |
| Outside – Low/High | 1–18 or 19–36 | 1:1 | Very easy |
| Outside – Dozens | 1–12, 13–24, or 25–36 | 2:1 | Very easy |
| Outside – Columns | One vertical column of 12 numbers | 2:1 | Very easy |
Take a closer look at the European and American wheel difference. European roulette has 37 pockets including a single zero, and the house edge is 2.70%. American roulette has 38 pockets because of the additional double zero, raising the house edge to 5.26%. This is not a minor detail—it changes your long-term value more than any bet selection strategy you will read about. If you have a choice, and most platforms offer one, lean toward European rules.
Some platforms also offer a “basket” bet (on 0, 00, 1, 2, 3) in American roulette, which pays 6:1. The catch? Its true odds are worse than either payout structure suggests, and many experienced players avoid it because it will never offer fair value compared to other inside bets. Check the game details on any site before playing.

Roulette inside bets vs outside bets: A Detailed Walkthrough
Now that the overview is clear, let me walk you through a complete round from the moment you enter a digital roulette lobby to the moment the dealer announces the result. This is the actual flow that the written guides rarely explain well.
Step 1: Set Your Session Bankroll
Before any chip is placed, decide how much you are prepared to lose. This amount should not be your grocery money, rent, or savings. It should be an entertainment expense, similar to what you would pay for a movie ticket or dinner out. I recommend breaking your session bankroll into units—for example, 100 units of $1 each. That unit structure makes bet sizing clearer as the game progresses.
Step 2: Choose a Bet Type Based on Your Tolerance
Let me give you a realistic example. You join an online table with an initial bankroll of 100 units. If you place straight-up bets of 1 unit each, you could hit a single number and receive 35 units in profit—but you are also likely to lose many spins in a row. Conversely, if you place outside red/black bets of 5 units each, you will win much more often, but each win only returns 5 units.
My general advice for new players is to start with outside bets to build confidence, then add one or two inside bets per session to understand how the rhythm feels. This is not a proven strategy—it is a way to learn without emotional whiplash.
Step 3: Place Your Chips
On a digital platform, you click a chip value, then click the area on the game layout where you want the bet. The interface may move your chip if it overlaps another player’s bet, or mark it with a slightly different color. On a live dealer table, you physically push chips onto the same felt positions. The rules of where you can place chips depend on the betting limits shown on screen.
Here is an example of a balanced betting ticket, purely as an illustration:
- 2 units on black (outside)
- 1 unit on the 1st dozen (outside)
- 1 unit on number 17 (inside straight up)
- 1 unit split between 13 and 16 (inside)
In this ticket, you have coverage across 28 numbers (black contains 18, the first dozen spans 12, plus 17 and the split). Notice the overlap: some numbers are covered by multiple bets. That is perfectly legal and common. The casino does not care if you duplicate coverage across different bet types.
Step 4: Watch the Spin and Calculate the Win
Suppose the ball lands on 17. Let’s calculate what happens with the ticket above:
- Black bet: 2 units at 1:1 pays a total of 4 units (your 2 back plus 2 profit).
- 1st dozen bet: 1 unit at 2:1 pays 3 units total (your 1 back plus 2 profit).
- Straight-up bet on 17: 1 unit at 35:1 pays 36 units total (your 1 back plus 35 profit).
- Split bet on 13/16: loses because the ball landed on 17, which is not part of that split.
Total profit in that example: 2 (black) + 2 (dozen) + 35 (straight up) = 39 units profit, before subtracting the losing split unit. This is why roulette can deliver large session swings: a single spin can turn a modest bankroll into a big one, but many spins will produce a small loss or a small win.
Now consider a different outcome. The ball lands on 5. Your black bet wins, your first dozen wins, but your straight-up on 17 loses, and the split on 13/16 loses. This produces 2 + 2 = 4 units profit, minus the 2 losing inside bets, giving you a net of 2 units profit. The point is that outside bets form the stable floor of your ticket.
Step 5: Walk Away on a Schedule
You should decide before you begin whether you are playing for a set amount of time or a set number of spins. I know players who set an alarm for 30 minutes and strictly stop when it rings. Others stop when they win a certain amount. Both are valid. What is dangerous is the “one more spin” mentality after a win or a loss. Decide your stopping condition while you are calm, and write it down if necessary.

Roulette for beginners: Common Mistakes to Avoid
I have seen the same roulette mistakes made in online forums and at physical tables for years. Here are the ones you should actively avoid:
Chasing Losses with Doubling Systems
The Martingale system—doubling your bet after every loss—feels intuitive because it seems that one win will erase previous losses. The problem is that real tables have table limits, and your bankroll has an upper bound. You can reach the table limit or run out of funds before the “inevitable” win arrives. I am not saying betting systems are useless; some players use them for structured gaming. But they do not change the mathematical edge the casino holds.
Ignoring the Double Zero in American Roulette
When you see a table that offers 0 and 00, remember the house edge doubles. Many online guides do not mention that the payout remains the same while the odds worsen. If you are trying to understand roulette in general, focus on European roulette first.
Placing Too Many Bets at Once
There is no rule against spreading chips across the entire table, but doing so often comes with diminishing returns. I have seen new players place 15 different bets on one spin, celebrating when the ball lands but still losing because most of their chips were on other numbers. If you win 5 units but spent 15 on losing bets, you take a net loss. Track the cost of the losing bets in your ticket, not just the winning ones.
Not Checking the Minimum Bet Requirement for Inside Bets
Some tables enforce a higher minimum bet for the entire inside area, not just per chip. For example, a $1 minimum chip may not be enough if the table minimum for the inside area is $5 per spin. This is not a hidden rule—it is usually displayed—but many beginners overlook it until the dealer stops them.

Roulette Betting Guide: A Quick Checklist Before You Play
You have read the definitions and the walkthrough. Before you place your first real-money wager on any platform, including sites like 9BET, run through this checklist:
- Confirm which roulette variation is active (European, American, or French).
- Check the table minimum and the maximum payout limit before betting.
- Decide on a bankroll amount that represents loss you can accept.
- Decide on a stop-win and stop-loss threshold.
- Start with 80% of your bets in the outside categories if you are new.
- Keep just 20% for exploratory inside bets, and only after you understand the pay table.
- Record what you learned after each session: which bets felt comfortable, which you misread, and where you lost track of the ticket value.
Roulette Betting Strategy for Beginners: A Balanced Approach
If you are looking for a sensible starting point rather than an aggressive system, consider a combination of covering two outside bets of different types. For instance, betting on black and the first dozen creates a structure where many numbers are covered, but so are enough numbers that your risk is still contained. This not a guaranteed win and loses when the ball lands on a red number from 13–36, but it provides more excitement than a single even-money bet.
Alternatively, some players enjoy making a “column plus dozen” cross. Bet one unit on the second dozen (13–24) and one unit on the second column (2–35). The overlap region—14 through 23—hits frequently and can produce a double win. But again, take this as a way to learn, not as a magic formula.
Understanding Roulette Odds and House Edge
Let’s take a moment to understand the house edge because it explains why no betting system is reliable. In European roulette, if you bet on a single number, you have a 1 in 37 chance of winning. The payout is 35:1, which implies the casino keeps a small slice of every win. Over thousands of spins, the casino’s edge will show through. This is not an accusation of unfairness—it is the fundamental reason the game exists.
What this means for you as a player is that you should measure success in terms of entertainment value, not income potential. Set realistic goals. Win or lose, the experience should fit your budget.
Frequently Asked Questions About Roulette Bets
Do outside bets or inside bets have better odds?
Outside bets, such as red/black or odd/even, win more frequently because they cover roughly half of the numbers. Their payout of 1:1 is lower, but the chance of winning is higher. Inside bets on specific numbers pay more but hit far less often. Neither choice changes the house edge beyond the type of wheel you choose.
Is the payout for a corner bet always 8:1?
Yes, in standard roulette, a four-number corner bet pays 8:1 on both European and American wheels. The odds of winning differ because American wheels have 38 numbers, but the payout is identical. This is part of why the house edge differs.
Can I bet on both red and black at the same time?
Yes, the casino will accept both bets, but it is pointless as a strategy. If the ball lands on red, your black bet loses, and if the ball lands on black, your red bet loses. You effectively pay the house edge for the privilege of watching the spin. Worse, if the ball lands on zero, both bets lose.
What is a French roulette “La Partage” rule?
La Partage is a rule some French and European roulette tables use, which returns half of your even-money bet when the ball lands on zero. This lowers the house edge even further. If you find a table that offers La Partage or “En Prison,” they are more favorable than a standard European table.
Does table history help predict the next outcome?
No. Roulette has no memory. The independent nature of each spin means previous numbers do not influence future results. Seeing five reds in a row does not increase the chance of black. Any system based on “hot” or “cold” numbers is based on a misunderstanding of probability.
The Bottom Line: Make Roulette a Structured Game
If you understand that roulette is a controlled form of entertainment with a built-in house advantage, you can enjoy it for exactly that. If, on the other hand, you enter it expecting a reliable way to make money, the game is likely to disappoint. The conditional verdict is this: play roulette only with money you can afford to lose, only with a predetermined plan, and only when you have a clear understanding of every bet you are placing.
That clarity comes from experience. Study the outside and inside bets, practice on free tables if the site offers them, then apply the same disciplined checklists to every real-money session. The wheel does not surrender its secrets easily, but that is precisely why it remains endlessly fascinating to players around the world.
