An inside bet is a roulette wager placed on the numbered grid, usually covering one to six specific numbers. Standard inside bets are straight-up, split, street, corner, and six-line wagers. They pay more than broad outside bets because they win less often, not because they offer a better mathematical deal.
Plain Talk
The roulette layout has two main betting zones:
- the inside, where chips are placed on, between, or around individual number boxes;
- the outside, where chips are placed on broad groups such as red, black, odd, even, dozens, or columns.
An inside bet is precise. A $5 chip directly on 17 wins only if 17 appears. A $5 chip on the line between 17 and 20 covers those two numbers. A chip at the intersection of four boxes covers all four.
The location of the chip is the instruction. A few millimeters can change which numbers are covered, so clear placement matters.

Standard Inside Bets
| Bet | Numbers covered | Common payout | Example placement |
|---|---|---|---|
| Straight-up | 1 | 35 to 1 | Center of one number box |
| Split | 2 | 17 to 1 | Line between adjacent numbers |
| Street | 3 | 11 to 1 | Outside edge of one horizontal row |
| Corner | 4 | 8 to 1 | Intersection of four numbers |
| Six-line | 6 | 5 to 1 | Outside edge between two adjacent rows |
The terms are based on the layout geometry. A player does not normally need to announce the bet if the chip is placed clearly before betting closes.
Straight-Up Bet
A Straight-Up Bet covers one number. On a standard wheel, it pays 35 to 1.
A $10 straight-up bet on 17 has these common outcomes:
- 17 wins: $350 profit, plus return of the $10 stake;
- any other pocket loses: the $10 is removed.
The large payout attracts attention, but the hit frequency is low:
- European single-zero wheel:
1 / 37 = 2.70%; - American double-zero wheel:
1 / 38 = 2.63%; - triple-zero wheel:
1 / 39 = 2.56%.
The payout usually remains 35 to 1 even when the wheel has extra zero pockets. That is why the house edge increases as pockets are added.
Split Bet
A Split Bet covers two adjacent numbers. The chip sits on the dividing line between them. The numbers must touch horizontally or vertically on the standard layout.
A $10 split on 17/20 usually pays 17 to 1. If either number hits, the player receives $170 profit plus the returned stake.
Not every pair of numbers can form a split. Numbers that are diagonal or separated on the grid are not a standard two-number split even if they look close on the wheel.
Street Bet
A Street Bet covers a row of three numbers, such as 16-17-18. It is placed on the outer edge of that row and usually pays 11 to 1.
On many layouts, the zero area supports special combinations that differ by wheel type and local rules. Players should not assume a zero combination merely from a familiar nickname. The printed layout and posted payouts control.
Corner Bet
A Corner Bet covers four numbers whose boxes meet at one point. A chip at the intersection of 16, 17, 19, and 20 covers all four and usually pays 8 to 1.
A chip that is not centered clearly on the intersection can create a dispute. Dealers routinely straighten unclear chips before the spin or ask the player to confirm the intended wager.
Six-Line Bet
A Six-Line Bet covers two adjacent streets, such as 13 through 18, and usually pays 5 to 1. It is the widest standard inside bet.
The six-line wins more often than a straight-up, split, street, or corner because it covers more pockets. Its payout is correspondingly smaller.
Probability on a European Single-Zero Wheel
A European wheel has 37 pockets: 1 through 36 plus a single 0.
| Bet | Win probability | Loss probability | Common payout |
|---|---|---|---|
| Straight-up | 1/37 = 2.70% | 36/37 | 35 to 1 |
| Split | 2/37 = 5.41% | 35/37 | 17 to 1 |
| Street | 3/37 = 8.11% | 34/37 | 11 to 1 |
| Corner | 4/37 = 10.81% | 33/37 | 8 to 1 |
| Six-line | 6/37 = 16.22% | 31/37 | 5 to 1 |
For a $10 straight-up wager:
EV = (1/37 × $350) - (36/37 × $10)
EV ≈ $9.46 - $9.73 = -$0.27
The expected loss is about $0.27 per $10 wager, corresponding to a house edge of approximately 2.70%.
Probability on an American Double-Zero Wheel
An American wheel has 38 pockets: 1 through 36, 0, and 00.
For a $10 straight-up wager:
EV = (1/38 × $350) - (37/38 × $10)
EV ≈ $9.21 - $9.74 = -$0.53
The expected loss is about $0.53 per $10 wager, or a 5.26% house edge.
The same standard inside-bet payout schedule is normally used, but the extra 00 pocket creates one more losing result.
Triple-Zero Wheels
A triple-zero wheel has 39 pockets. If standard payouts remain unchanged, the house edge on ordinary bets rises to approximately 7.69%.
A player who focuses only on the 35-to-1 sign may miss that the wheel contains 0, 00, and 000. Before betting, count the zero pockets. Wheel type matters more than whether the chip is placed on 17, a split, or a corner.
Do All Inside Bets Have the Same House Edge?
On a given standard wheel, most ordinary inside bets have the same house edge because the payouts are scaled to the number of pockets covered.
For example, on a double-zero wheel:
- straight-up covers 1 number and pays 35 to 1;
- split covers 2 and pays 17 to 1;
- street covers 3 and pays 11 to 1;
- corner covers 4 and pays 8 to 1;
- six-line covers 6 and pays 5 to 1.
Their hit frequencies differ, but their expected percentage loss is generally the same: approximately 5.26% on the standard American wheel.
Exceptions can exist for unusual combinations or special payouts. The most famous is the American five-number basket—0, 00, 1, 2, and 3—which traditionally pays 6 to 1 and carries a higher house edge than standard bets. Always check the actual rule and payout.

Inside Bets Versus Outside Bets
| Feature | Inside bets | Outside bets |
|---|---|---|
| Coverage | 1 to 6 specific numbers | 12 to 18 broad numbers |
| Typical hit frequency | Lower | Higher |
| Typical payout | 5 to 1 through 35 to 1 | Usually 1 to 1 or 2 to 1 |
| Volatility | Higher | Lower |
| House edge on same wheel | Usually the same | Usually the same, subject to special rules |
Outside bets feel steadier because they hit more often. Inside bets create larger but less frequent wins. Neither category changes the wheel’s memory: every spin is a new random outcome.
On some single-zero games, even-money outside bets may receive La Partage or En Prison treatment when zero appears. Those rules can reduce the house edge on qualifying outside bets. They generally do not improve inside bets.
A US-Dollar Session Example
A player places five $2 straight-up wagers on every spin, for a total of $10 per spin. After 100 spins:
Total action = $10 × 100 = $1,000
On a double-zero wheel:
Expected loss = $1,000 × 5.26% ≈ $52.60
The player may finish far above or below that figure because straight-up results are volatile. The $52.60 is a long-run average, not a prediction of the exact 100-spin result.
The same player may say, “I only bet $2,” but the relevant action is $10 per spin because five separate chips are exposed.
Combining Inside Bets
Players often create coverage patterns by combining several inside bets. Examples include:
- one straight-up plus two splits;
- a corner with neighboring straight-ups;
- multiple streets;
- a section of the wheel represented through several layout bets.
The combined wager should be evaluated by total money at risk, not by the appearance of one chip denomination.
If a player places eight $5 inside bets, the spin exposure is $40, even though each individual wager is small.
Neighbors and Wheel Sections
Some roulette formats offer announced or racetrack bets covering numbers that are adjacent on the wheel rather than adjacent on the table grid. These may be composed of several straight-up and split wagers.
They are still made from inside-bet components, but the exact chip distribution and total cost depend on the accepted call. Players should confirm how many units are required before saying “neighbors,” “tiers,” “orphans,” or another section name.
Chip Placement and Dealer Procedure
Inside bets create detailed chip-reading work. The dealer must determine:
- whose chip it is;
- the amount or number of units;
- the exact numbers covered;
- whether the bet was placed before “no more bets”;
- whether stacked chips are stable and readable;
- whether a late correction changed the intended wager.
Roulette often uses non-value color chips assigned to individual players. Their cash value is set when purchased and may be different from another player’s identical-looking stack. This helps the dealer identify ownership on a crowded inside layout.
From the Casino Side
A table dominated by inside action can be slower than one dominated by outside bets. After the ball lands, the dealer must:
- mark the winning number;
- clear losing chips without disturbing winners;
- identify every winning placement;
- calculate each payout;
- pay from the outer winners toward the number according to procedure;
- remove the marker only when settlement is complete.
Common operational risks include:
- a chip bridging two intended locations;
- a player moving a bet after betting closes;
- a dealer misreading a split as a straight-up;
- an incorrect payout multiple;
- a hidden chip under another player’s stack;
- confusion over the assigned value of color chips;
- a claim made after losing chips have been cleared.
Clear hands, visible chips, and prompt questions reduce disputes. A player should never reach onto the layout while the dealer is clearing or paying.
Common Misunderstandings
“Inside bets pay more, so they have a better return.”
They pay more because they cover fewer numbers. On the same standard wheel, most ordinary bets carry the same house edge.
“A number next to the last winner on the layout is more likely.”
Layout adjacency does not affect the next wheel outcome. The grid is a betting map, not a probability engine.
“Covering many numbers guarantees a profit.”
Covering more numbers increases hit frequency but also increases total cost. A win on one position may be smaller than the losses on the others.
“A straight-up win pays 36 to 1.”
It commonly returns 36 units including the original stake, but the profit payout is 35 to 1.
“The dealer will know what I meant.”
The dealer settles the placement that was accepted. Intent that was not communicated clearly may not control a dispute.
A 20-Second Inside-Bet Check
Before the spin, ask:
- Is this a single-, double-, or triple-zero wheel?
- How many total dollars are exposed this spin?
- Exactly which numbers does each chip cover?
- What is the posted payout?
- Can I tolerate a long sequence of misses?
That check is more useful than searching the board for a “hot” number.
Hard Truth
Inside bets create vivid wins by concentrating risk. The payout is larger because the hit is rarer, not because the wheel became generous.
