Reading the Layout Before You Put a Chip Down
A roulette table looks like a grid of numbers surrounded by a betting area, and most of the confusion for a new player comes from not knowing that the grid and the outer area are two different betting systems. The numbered grid is where you bet on individual numbers and small groups of numbers. The outer area is where you bet on larger categories like red or black, odd or even, and the first, second, or third dozen. This article is about the numbered grid, which the casino calls the inside bets.
The first thing to understand is that every bet on the grid pays based on how many numbers it covers. A bet on a single number covers one pocket out of the wheel. A bet on two numbers covers two pockets. The payout shrinks as the coverage grows, but it never shrinks in exact proportion to the coverage. That gap between the payout and the true odds is where the house edge lives, and it is the same on every inside bet on a given wheel under the same rule set.
Before you sit down, look at the table's posted minimum and maximum for inside bets. Some tables have a lower minimum for outside bets and a higher minimum for inside bets, or a minimum that applies to the total of all your inside chips. The dealer or the digital display will tell you. You can also ask the dealer to explain a bet before you place it; that is a normal part of how a table runs.
The Sequence of a Round
A round of roulette moves through a fixed sequence. First, the dealer closes the previous round by clearing losing chips and paying winners. Then the dealer announces that betting is open, and players place chips on the layout. You can place multiple bets in the same round, and you can keep placing them until the dealer calls for no more bets or waves a hand over the layout. After that, the wheel is spun and the ball is released in the opposite direction. When the ball drops into a pocket, the dealer marks the winning number on the layout, clears the losing bets, and pays the winners. The sequence then repeats.
Two procedural points matter here. First, once the dealer calls no more bets, you cannot touch your chips. If you try to move a chip after the call, the dealer will tell you to leave it or remove your hand. Second, when you win, the dealer pays you in chips and leaves your original bet on the layout. You pick up the winnings and decide whether to leave the original bet for the next round or take it back. Leaving it is called letting it ride, and it is a choice, not a requirement.
What Each Number Bet Covers
The inside bets are named by how many numbers they cover and where the chip sits. A straight-up bet is a chip placed entirely inside a single number's square. A split bet sits on the line between two numbers and covers both. A street bet sits on the outer edge of a row and covers the three numbers in that row. A corner bet sits on the intersection of four numbers and covers all four. A six-line bet sits on the outer edge where two rows meet and covers six numbers.
The table below lays out the coverage and the payout for each of these bets. The payout is the amount the house pays on top of your original stake, expressed as a multiple of that stake.
| Bet type | Numbers covered | Payout | Where the chip sits |
|---|---|---|---|
| Straight-up | 1 | 35 to 1 | Inside a single number's square |
| Split | 2 | 17 to 1 | On the line between two numbers |
| Street | 3 | 11 to 1 | On the outer edge of a row |
| Corner | 4 | 8 to 1 | On the intersection of four numbers |
| Six-line | 6 | 5 to 1 | On the outer edge where two rows meet |
Notice the pattern. A straight-up bet covers one number and pays 35 to 1. A split covers two numbers and pays 17 to 1, which is close to half of 35 but not exactly. A street covers three numbers and pays 11 to 1. A corner covers four and pays 8 to 1. A six-line covers six and pays 5 to 1. If the payouts matched the true odds exactly, a bet covering two numbers would pay 17.5 to 1 on a wheel with 37 pockets, and the fractions would continue from there. The house rounds the payout down to a whole number, and that rounding is a large part of the house edge on inside bets.
How the Wheel Type Changes the Arithmetic
Roulette wheels come in two common layouts, and the difference is a single pocket. A European wheel has 37 pockets, numbered 0 through 36, with a single zero. An American wheel has 38 pockets, numbered 0 through 36 plus a double zero. The extra pocket on the American layout increases the house edge on every bet, including the inside bets, because the payout for a straight-up bet remains 35 to 1 while the number of losing pockets grows by one.
You can tell which wheel you are at by looking at the layout. If the grid shows both a 0 and a 00, it is an American wheel. If it shows only a 0, it is a European wheel. Some venues also offer a French layout with different rules for even-money outside bets, but those rules do not change the inside bets covered here. The wheel type is printed on the layout and usually on a plaque at the table, and the dealer can confirm it.
For any given inside bet, the house edge is the same across all inside bets on the same wheel under the same rule set. A straight-up bet and a six-line bet lose at the same expected rate per unit wagered, because the payout scale is built from the same rounding. What changes is the variance: a straight-up bet pays rarely but pays a large multiple when it hits, while a six-line bet pays more often but a smaller multiple. The choice between them is a choice about how your session plays out, not a choice that changes the built-in edge.
Placing the Bet and Handling the Payout
When you want to bet a number, place the chip fully inside the number's square. If the chip touches the line, the dealer may read it as a split bet, which changes what you are betting on. The dealer will usually confirm a large or unusual bet by repeating it back to you, and you should correct any misread before the spin. For a split, place the chip so it straddles the line between the two numbers. For a street, place it on the outer edge of the row, on the line that separates the grid from the outside betting area. For a corner, place it on the intersection where four squares meet. For a six-line, place it on the outer edge where two rows meet, on the same boundary line.
If your number wins, the dealer pays you in chips and leaves your original bet in place. You can pick up the payout and the original bet together, or you can leave the original bet for the next round. If you leave it and it wins again, the payout is calculated the same way. Nothing about a previous win changes the odds on the next spin, because each spin is an independent event produced by the wheel and the ball, not by the history of the table.
One procedural mistake new players make is stacking chips from different denominations on the same number and then arguing about the payout. The dealer pays each chip according to its denomination, and a mixed stack can be misread. A cleaner approach is to bet a single denomination per number, or to announce the total when you place a mixed stack. Another mistake is reaching for a winning bet before the dealer has finished clearing the table. Wait for the dealer to push the payout to you, then take it. A third mistake is placing an inside bet after the no-more-bets call, which the dealer will return to you or leave in place at the table's discretion.
What Strategy Means for Number Bets
Roulette is a game of independent spins, and no betting pattern changes the edge on any inside bet. A progression that raises your stake after a loss does not make a number more likely to appear; it redistributes when the losses and wins land. A straight-up bet on a number that has not appeared in many spins is no more likely to hit than any other number, because the wheel has no memory. The only choices that change your expected rate of loss are the wheel type and the rule set, and the only choices that change your session's variance are the bet types you select and how many numbers you cover at once.
If you want to cover more numbers in a single spin, you can place multiple inside bets, or you can use a bet that covers a group. A six-line bet covers six numbers with one chip, while six straight-up bets cover six numbers with six chips. The total amount wagered differs, and the payout if one of the numbers hits differs, but the house edge on the total wagered is the same under the same wheel and rule set. The choice is about convenience and how you want the payouts to land, not about changing the arithmetic.
Some players ask about a strategy chart for roulette the way blackjack has a basic-strategy chart. Roulette has no equivalent, because there is no decision after the bet is placed. In blackjack, the player chooses whether to hit, stand, split, or double, and a published chart derives from the exact rule set in use. In roulette, the only decision is which bets to place and how much to stake, and that decision is complete before the spin. Any chart you see for roulette is a staking plan, not a strategy in the blackjack sense, and it does not alter the edge.
FAQ
Can I bet on more than one number at the same time?
Yes. You can place as many inside bets as the table minimum and maximum allow, and you can mix bet types in the same round. Each bet is settled independently against the winning number.
What happens if the ball lands on zero when I bet on a number?
Zero is a number like any other on the layout. If you have a straight-up bet on zero, it pays 35 to 1. If you have a bet on another number or group that does not include zero, that bet loses. The zero pocket is one of the losing pockets for every bet that does not cover it.
Does betting the same number every spin improve my chances?
No. Each spin is an independent event, and the probability of any given number appearing is the same on every spin, regardless of what has appeared before. Betting the same number every spin changes the pattern of your session, not the underlying probability.
