High or low roulette is one of the simplest wagers on the roulette layout, but many new players still misunderstand what it covers. In standard roulette, it means betting that the winning number will land in either 1-18 or 19-36, with 0 and 00 usually losing. Knowing how high or low roulette works matters because the wheel type, table rules, and even-money exceptions can change the true cost of the bet.
What high or low roulette Means
High or low roulette is an even-money outside bet on whether the winning roulette number will fall in the low range of 1-18 or the high range of 19-36. It pays 1:1 when your chosen range hits, while 0 and 00 usually lose unless special even-money rules apply.
In plain English, you are not picking one exact number. You are choosing one half of the numbered board:
- Low = 1 to 18
- High = 19 to 36
If the ball lands on any number in your chosen half, the bet wins. If it lands in the other half, it loses. On most tables, the green 0 on European wheels and 0/00 on American wheels are losing outcomes for both high and low.
This term matters in roulette because high/low is one of the most common outside bets. It is beginner-friendly, easy for dealers to settle, and often used by players who want lower variance than straight-up number betting. It is also one of the bets most affected by the wheel format:
- Single-zero roulette is usually less expensive mathematically
- Double-zero roulette increases the house edge
- French rules may soften losses on even-money bets
You may also see the same idea labeled in French-style roulette as:
- Manque = low, 1-18
- Passe = high, 19-36
How high or low roulette Works
High or low roulette works as a standard outside wager placed on the betting layout before the dealer calls “no more bets” or the online game locks the spin.
The basic mechanic
- You place a chip on 1-18 or 19-36
- The dealer or live game spins the wheel and launches the ball
- The ball lands in a numbered pocket
- Your bet is settled: – Win if the number is in your selected range – Lose if it lands in the opposite range – Usually lose if it lands on 0 or 00
The usual payout is 1:1. That means:
- A $10 winning high bet returns $10 profit
- You also keep your original $10 stake unless you take it down before the next spin
Important wheel rule: the wheel order does not define “high” or “low”
A common misunderstanding is thinking high or low refers to the physical top half or bottom half of the roulette wheel. It does not.
Roulette wheel numbers are arranged in a mixed order. The high/low bet is based on the number range on the layout, not the physical position of pockets on the wheel.
So if the ball lands on 22, high wins, even if 22 is physically positioned next to several low numbers on the wheel.
Where the bet sits on the layout
On most roulette layouts, high/low appears in the outside betting area:
- 1-18 on one side
- 19-36 on the other side
It sits alongside other even-money bets such as:
- Red/Black
- Odd/Even
These bets are operationally simple for dealers because they cover broad groups of numbers and settle quickly.
Wheel type changes the math
The most important factor is how many non-paying green pockets the wheel has.
| Wheel type | Winning numbers for High or Low | Green pockets that usually lose | Typical even-money treatment |
|---|---|---|---|
| European / Single-zero | 18 | 1 (0) | 0 usually loses |
| French roulette | 18 | 1 (0) | 0 may trigger la partage or en prison |
| American / Double-zero | 18 | 2 (0, 00) | 0 and 00 usually lose |
| Triple-zero roulette | 18 | 3 (0, 00, 000) | All green pockets usually lose |
That is why the same high/low bet can be better or worse depending on the table you choose.
The math behind the bet
On a standard single-zero wheel, the probability of winning a high or low bet is:
- 18 winning numbers out of 37 total pockets
On a double-zero wheel, it becomes:
- 18 winning numbers out of 38 total pockets
Because the payout remains 1:1 even though the green pockets are losing numbers, the house keeps a mathematical edge.
Expected value example
For a $1 high bet on a European wheel:
- Win probability = 18/37
- Lose probability = 19/37
Expected value:
[ (18/37 \times 1) + (19/37 \times -1) = -1/37 ]
That equals an average loss of about 2.70% per unit bet over the long run.
For a $1 high bet on an American wheel:
[ (18/38 \times 1) + (20/38 \times -1) = -2/38 ]
That equals about 5.26% per unit bet over the long run.
If a French table applies la partage on even-money bets, the long-run cost of high/low can be lower because a zero may return half your stake instead of taking the full amount.
How it is handled in real casino operations
In a land-based casino, high/low is straightforward for the dealer and floor team:
- The player places chips in the outside-bet box
- The dealer spins and calls the result
- Losing outside bets are cleared
- Winning even-money bets are paid at 1:1
In online roulette, the same bet appears as a clickable section of the digital layout. The back-end game logic automatically checks whether the result falls within 1-18 or 19-36 and settles the bet according to the wheel rules shown in the game info panel.
For live dealer roulette, the process is similar to a physical table, but settlement is handled by the platform interface after the winning number is confirmed.
Where high or low roulette Shows Up
Land-based casino roulette tables
This is the most familiar setting. On a physical roulette felt, high and low are clearly marked in the outside betting area. Players often use these bets when they want simple action without tracking individual numbers or combinations.
At the table, the dealer can settle high/low quickly because it is an all-or-nothing outside wager with a fixed even-money payout.
Online casino roulette
In RNG roulette and live dealer roulette, high/low appears as a standard interface option on the digital layout. It is common across:
- European roulette
- American roulette
- French roulette
- Some auto roulette and electronic roulette games
Online, the main thing to check is the game rules panel, because the bet name is the same but the wheel format may be different.
Electronic roulette terminals
Many casinos and gaming lounges use electronic roulette stations connected to a live wheel or automated wheel. High/low is often one of the easiest bets for casual players using these terminals, since the touch-screen layout clearly highlights 1-18 and 19-36.
French-style roulette tables
In French roulette, you may not see the English labels “high” and “low” as prominently. Instead, the same bet may appear as:
- Manque for 1-18
- Passe for 19-36
That is the same core bet, just under traditional terminology.
Why It Matters
For players
High or low roulette matters because it is one of the lowest-complexity bets in the game.
Its appeal is simple:
- Easy to understand
- Easy to place
- Wins almost half the time
- Lower volatility than betting a single number
That said, “wins often” does not mean “beats the game.” The house edge still applies, and the wheel type makes a major difference. A beginner who does not notice whether the table is single-zero or double-zero can end up playing a materially worse version of the same-looking bet.
For operators
For casinos and online operators, high/low is a core part of roulette’s outside-bet offering.
Operationally, it helps because:
- It is familiar to beginners
- It supports faster decision-making at the table
- It reduces disputes because settlement is clear
- It fits naturally into land-based, live dealer, and RNG roulette products
It also matters from a product-design standpoint. If an operator offers multiple roulette variants, clearly displaying whether a table is European, American, or French affects transparency and player trust.
For compliance and game transparency
This bet is simple, but the rules around it still need to be presented clearly. The biggest transparency issue is how green pockets are treated.
Players should be able to verify:
- Whether the wheel is single-zero, double-zero, or triple-zero
- Whether even-money bets lose fully on zero
- Whether la partage or en prison applies
- What the table minimum and maximum limits are
When those details are not obvious, confusion and complaints can follow.
Related Terms and Common Confusions
| Term | How it relates to high or low roulette | Key difference |
|---|---|---|
| 1-18 / 19-36 | This is the standard layout label for high and low | Same bet, different wording |
| Manque / Passe | French terms for low and high | Same bet, traditional French labels |
| Red / Black | Another even-money outside bet | Based on color, not number range |
| Odd / Even | Another even-money outside bet | Based on parity, not range |
| Dozens | Covers 12 numbers at a time | Pays 2:1 instead of 1:1 |
| Columns | Covers one vertical column of 12 numbers | Also pays 2:1 and follows the table grid, not the number range |
The most common misunderstanding
The biggest confusion is this:
High or low roulette does not mean betting on a high section or low section of the wheel itself.
It simply means betting on:
- Low numbers: 1 through 18
- High numbers: 19 through 36
A second common mistake is assuming 0 counts as low because it is numerically lower than 1. In roulette, it does not. Zero is a separate green pocket and usually loses for both high and low.
Practical Examples
Example 1: Standard European roulette
You place $20 on Low (1-18) at a single-zero roulette table.
Possible outcomes:
- Ball lands on 12 → your bet wins
- Profit = $20
- Total returned = $40 including your original stake
If the ball lands on:
- 25 → your bet loses
- 0 → your bet also loses on most standard European tables
This is the classic version of high or low roulette.
Example 2: American roulette and the extra losing pocket
You place $10 on High (19-36) at an American double-zero table.
Outcomes:
- Ball lands on 31 → you win $10
- Ball lands on 8 → you lose $10
- Ball lands on 00 → you also lose $10
That extra 00 is why the same bet costs more, mathematically, on American roulette than on European roulette.
Example 3: French roulette with la partage
You place $40 on Low at a French roulette table that uses la partage for even-money bets.
If the ball lands on 0:
- You do not necessarily lose the full $40
- Instead, you typically get half back
- Loss = $20, return = $20
That special rule improves the long-term value of even-money bets like high/low, red/black, and odd/even.
Example 4: Long-run cost comparison
Suppose you make 100 bets of $10 each on high or low.
Total staked: $1,000
Theoretical long-run expectation:
- European wheel: expected loss of about $27
- American wheel: expected loss of about $53
That does not predict what will happen in one session. You could win or lose much more in practice. It simply shows how wheel choice affects long-run cost.
Limits, Risks, or Jurisdiction Notes
Rules for high or low roulette can vary more than beginners expect.
What can vary
Before you play, check:
- Wheel type: single-zero, double-zero, or triple-zero
- Even-money zero rule: full loss, la partage, or en prison
- Table limits: minimum and maximum stakes
- Game format: live dealer, RNG, or electronic terminal
- Regional availability: some wheel types are more common in certain markets
Common mistakes
The most frequent player errors are:
- Thinking 0 counts as low
- Forgetting that 00 also kills the bet on American tables
- Confusing high/low with a wheel-sector bet
- Assuming all roulette tables have the same house edge
- Using a betting progression and believing it changes the math
A progression system like Martingale may change the size and timing of your bets, but it does not remove the house edge. Table limits and bankroll limits can stop progression strategies quickly.
What to verify before acting
If you are choosing between tables or games, verify:
- The wheel format
- The payout table
- Any special even-money rule
- The staking limits
- Whether the operator is allowed to offer that version in your jurisdiction
For online play, check the game information screen rather than assuming all roulette products use the same rules.
If gambling stops feeling entertaining, use deposit limits, time limits, cool-off tools, or self-exclusion options where available.
FAQ
What does high or low mean in roulette?
It means betting on whether the winning number will be in 1-18 or 19-36. It is an even-money outside bet.
Does 0 count as high or low in roulette?
No. In standard roulette, 0 is a separate green pocket and usually loses for both high and low. On American wheels, 00 also loses.
What is the payout for a high or low roulette bet?
The standard payout is 1:1. If you bet $10 and win, you earn $10 in profit and keep your original $10 stake.
Is high or low roulette better on European or American wheels?
Usually European roulette is better because it has only one green zero pocket instead of two. That lowers the house edge on even-money bets like high and low.
Is high or low roulette the same as manque and passe?
Yes. In French roulette, manque means 1-18 and passe means 19-36.
Final Takeaway
High or low roulette is a simple outside bet on whether the result lands in 1-18 or 19-36, but the details still matter. The bet itself is easy; the important part is checking the wheel type, the zero rules, and whether any French even-money protection applies. If you understand those basics, you can read any high or low roulette table correctly and avoid the most common beginner mistakes.
