The layout separates inside from outside before you place a single chip
When you first sit at a roulette table, the felt looks like a grid of numbers surrounded by boxes for broader categories. The inner grid, where the individual numbers live, is the inside betting area. The boxes around it—red or black, odd or even, high or low, dozens, columns—are the outside. Everything you are about to read concerns the inner grid only, because that is where the payout multiples climb and where most of the confusion for a new player begins.
A European wheel has 37 pockets numbered 0-36. An American wheel has 38, adding a double zero. The layout you bet on mirrors those numbers. You can put chips directly on a number, on a line between numbers, or on a corner where several numbers meet. Each position corresponds to a different bet, and each bet pays according to how many numbers it covers. Fewer numbers covered means a larger payout multiple, but also a smaller chance of winning on any given spin.
What each inside bet covers and what it pays
Inside bets are named by the shape they make on the layout. A straight-up bet sits fully on one number. A split straddles the line between two adjacent numbers. A street runs across a row of three. A corner sits where four numbers touch. A six-line covers two adjacent streets. On layouts that include a zero, a trio covers the zero and two numbers, and a basket covers zero, double zero and the two—though the basket exists only on American wheels.
The payout for each bet is fixed by the number of pockets it covers. A straight-up bet pays 35 to 1 because it covers one pocket out of 37 on a European wheel. A split pays 17 to 1, a street pays 11 to 1, a corner pays 8 to 1, and a six-line pays 5 to 1. These are the standard multiples printed on the table or shown in the game information panel. Always check the panel for the wheel you are playing, because the presence of a double zero changes the number of losing pockets without changing the payout multiples.
| Bet | Numbers covered | Standard payout | Where the chips go |
|---|---|---|---|
| Straight-up | 1 | 35 to 1 | Fully inside one number box |
| Split | 2 | 17 to 1 | On the line between two numbers |
| Street | 3 | 11 to 1 | On the outer edge of a row of three |
| Corner | 4 | 8 to 1 | On the corner where four numbers meet |
| Six-line | 6 | 5 to 1 | On the outer edge between two rows |
| Trio | 3 | 11 to 1 | On the line where zero meets two numbers |
| Basket (American only) | 5 | 6 to 1 | On the corner covering zero, double zero and the two |
The house edge does not improve by spreading chips differently
Here is the counterintuitive part that most new players miss: on a European wheel, nearly every inside bet carries the same house edge. A straight-up bet on a single number and a six-line covering six numbers both return the same long-run percentage to the player, because the payout multiple scales exactly with the number of pockets covered. The house edge and RTP are complements—they sum to 100% for the same bet under the same rule set. Changing the shape of your bet changes the frequency of wins and the size of the payout, but it does not change the built-in edge on a European layout.
The American wheel is the exception that matters. Adding a double zero adds one more losing pocket without adding any new payout. That extra pocket increases the house edge on every inside bet compared with the European layout. The basket bet on an American wheel is worse still, because it covers five numbers but pays only 6 to 1, which is a lower multiple than the five covered pockets would justify on a pure scaling basis. If you have a choice of wheel, the European layout is the better rate of loss for the same bets.
How a round goes from buy-in to settlement
You buy chips at the table from the dealer, not from a cashier, and roulette chips are typically colour-coded so the dealer can tell your stack from the next player's. You place inside bets by setting chips on the layout before the dealer closes betting. On a live table, the dealer announces that no more bets are accepted, spins the wheel, and releases the ball in the opposite direction. When the ball settles, the dealer marks the winning number, clears losing bets, and pays winners at the multiples above. Your original winning chip stays on the layout and is returned with the payout.
Online roulette follows the same sequence, but the interface does the clearing and paying for you. You select a chip value, click the position on the layout, and the bet appears. A spin button starts the round. After the result, the cashier balance updates automatically. The main difference is speed: an online round can run in seconds, so the number of decisions per hour is far higher than at a live table. That speed changes how quickly variance shows up, not the underlying edge.
Three procedural mistakes that cost new players more than the edge
The first mistake is betting after the dealer has called no more bets. On a live table, a late chip is a dead chip—it may be returned or it may sit unplayed, and neither outcome is the bet you wanted. Watch the dealer's hand and the ball, not just the layout. The second mistake is stacking chips in a way that makes the intended bet unclear. A chip that is half on a number and half on a line may be interpreted as a split, or it may be pushed back to you. Place each bet deliberately, fully inside the box or fully on the line, and let the dealer confirm ambiguous positions.
The third mistake is assuming that a hot number or a pattern of recent results changes what will happen next. Each spin is an independent event generated by the wheel or the RNG. The ball has no memory. A number that has not appeared for fifty spins is not due, and a number that has appeared three times in a row is not hot in any predictive sense. Inside bets feel precise because they target specific numbers, but that precision is about payout structure, not about forecasting.
Where the exact rules for your table live
Roulette rules vary by venue and by software provider. Some tables use a European wheel but apply a rule that returns half your even-money stake when zero appears, which changes the edge on outside bets only. Some online versions allow racetrack betting, which is a way of placing groups of inside bets that follow the wheel's physical order rather than the layout order. Some tables have a maximum inside bet that is lower than the outside maximum, because the payout multiples are higher. None of these details are universal.
The table rules are printed on the felt or shown in the game information panel before you sit down or open the game. Read them for the wheel type, the payout multiples, and any special rules that apply to zero. If you plan to use a published betting chart or a strategy reference, remember that any chart derives from the specific rule set in use—deck count, wheel type, and special rules all change the correct play. A chart built for one wheel is not automatically right for another.
FAQ
What is the best inside bet in roulette?
On a European wheel, the straight-up, split, street, corner and six-line bets all carry the same house edge, so no inside bet is mathematically better than another. The choice is about variance: a straight-up bet wins rarely but pays 35 to 1, while a six-line wins more often but pays only 5 to 1. The American basket bet is the one inside bet with a genuinely worse edge, because its payout does not scale with the five numbers it covers.
Can I bet on zero as an inside bet?
Yes. Zero sits on the inside layout and can be bet straight-up like any other number. On a European wheel it is one pocket out of 37, so a straight-up bet on zero pays the same 35 to 1 as a straight-up bet on any other number. On an American wheel, zero is one of two green pockets, and both can be bet individually or combined in the basket bet.
How many inside bets can I place on one spin?
As many as the table maximum allows. You can cover a single number, split several pairs, add a street and a corner, and still bet outside at the same time. Each bet settles independently, and each carries its own payout multiple. Covering more numbers increases your chance of winning something on a given spin, but the house edge on each individual bet remains the same on a European wheel.
