This evidence-led guide compares the most commonly encountered roulette rules and wheel layouts so readers can understand how pockets, zeroes, special rules and payouts interact with long‑run odds. This page does not advise anyone to bypass self‑exclusion. GAMSTOP covers online gambling businesses licensed to operate in Great Britain; being outside GAMSTOP or holding a foreign licence is not equivalent to UK Gambling Commission (UKGC) authorisation or to the consumer protections that UK‑licensed sites must follow. If you have an active self‑exclusion, gambling harm concerns, or a problem with gambling, do not use this page to find another place to gamble.

How roulette variants differ
Roulette variants are defined by the wheel layout (how many numbered pockets and whether there is a single or double zero), dealer and table procedures, and the presence or absence of special rules that affect specific bet types. The most important practical differences for players are:
- Number of pockets and the presence of one or more zeros, which changes the probability that any single bet will win.
- Special rules on even‑money bets (for example la partage or en prison), which can change the treatment of a stake when the ball lands on zero.
- Table limits and bet availability (some live tables limit certain bets or chip denominations).
- Whether the table is a live streamed game with a human croupier or a digitally dealt RNG game, which affects session experience but not the theoretical house advantage.
Below are variant‑specific explanations followed by a dated comparison table and guidance on what to check before you play.
European single-zero roulette
European roulette typically refers to a wheel with one zero and numbers 1–36 plus a single 0. Common characteristics include the same standard payouts found in most roulette tables: a straight‑up (single number) payout typically expressed as 35:1, column and dozen payouts of 2:1, and even‑money bets that pay 1:1. The one zero increases the probability that a bet on numbers 1–36 will lose compared with a hypothetical zero‑free wheel; the presence of a single zero is part of the house mathematical structure of the game.
What to check on a European single‑zero table before you play:
- Table limits: minimum and maximum stakes can vary widely between RNG tables and live tables.
- Available bet types: all standard inside and outside bets should be listed in the table rules.
- Payout schedule: confirm numeric payout ratios on the table’s rules page; most European tables use conventional payouts but sites should show this explicitly.
- Licensing and regulation information: check whether the operator is licensed and which regulator issued the licence; this affects complaints and recourse options.
French roulette and la partage or en prison
French roulette is usually played on a wheel with a single zero but offers additional rule options that can reduce the effective loss on specific even‑money bets when the ball lands on zero. Two historically common treatments are:
- La partage — when an even‑money bet (for example red/black, odd/even, 1–18/19–36) loses because the ball lands on zero, the player immediately loses half the stake and the other half is returned.
- En prison — when an even‑money bet lands on zero, the stake is held (imprisoned) for the next spin; if the imprisoned bet wins on the next spin it is returned with no additional winnings, and if it loses the stake is forfeited.
These rule options only apply to qualifying even‑money bets and only when explicitly offered at the table; they are not universal. When la partage or en prison is in force the expected loss on a qualifying even‑money wager is reduced relative to a table without those rules, because the zero outcome does not cause a full immediate loss for that stake. Always check the table rules or dealer announcements for the presence and exact application of la partage or en prison.
American double-zero roulette
American roulette commonly features two zero pockets (0 and 00) in addition to numbers 1–36. The payouts for winning wagers are usually the same nominal ratios (for instance straight‑up 35:1), but the additional zero increases the chance the ball will land on a zero pocket on any spin. That change in the wheel composition alters the statistical frequency of winning outcomes for all bets where the zero pockets are losing outcomes.
Important practical points for American double‑zero tables:
- Confirm payouts and whether any special rules (for example la partage) are offered — they are less commonly applied on traditional American roulette but conventions vary at different tables and operators.
- Table limits and the distribution of bet types (some live American tables restrict large inside bets or limit maximums on particular bets).
- Where a live table is offered by a UK‑facing operator, check licensing and whether the operator is part of GAMSTOP coverage if you are in Great Britain; a foreign licence or being outside GAMSTOP does not provide UK consumer protections.
Live roulette: stream, limits and rule checks
Live roulette is a streamed game with a human dealer and a physical wheel (or certified automated wheel). Live tables can be presented in different formats: studio tables, casino‑floor tables, or automated live wheels. Key checks for live roulette:
- Stream provenance: look for platform details and whether the provider publishes technical or fairness information. RNG numbers are not used in a live wheel — instead, regulatory oversight and provider certification are the mechanism for impartial outcomes.
- Dealer procedure and announcement of special rules: dealers or the on‑screen rule panel should state whether la partage/en prison applies and how the table treats zero outcomes.
- Table minimums and maximums: live studios frequently set higher minimums than RNG tables and can impose tighter maximums on some bets; check before joining a table to avoid session interruptions.
- Latency and geography: live streams may be regionally restricted; check whether the streamed session allows play from your jurisdiction and which licence the operator holds.

Comparison table (updated 5 September 2026)
| Variant | Wheel pockets | Zeros | Special rules commonly available | Typical eligible bets | Typical straight‑up payout | Typical even‑money payout | Table limits (example range) |
|---|---|---|---|---|---|---|---|
| European (single‑zero) | 1–36 plus 0 | Single 0 | Occasionally none; some tables show la partage or en prison | Inside bets, outside bets, columns, dozens | 35:1 (standard table payout) | 1:1 (subject to table rules) | £0.10 to £500+ depending on operator and live/RNG |
| French (single‑zero with variants) | 1–36 plus 0 | Single 0 | La partage or en prison often offered for even‑money bets | Same as European; additional announced table rules | 35:1 (standard table payout) | 1:1; la partage/en prison affect treatment of 0 outcome | £0.10 to £500+; live French tables may set higher minimums |
| American (double‑zero) | 1–36 plus 0 and 00 | Double 0 | Generally no la partage/en prison; conventions vary | Inside/outside, some house variants restrict special bets | 35:1 (standard table payout) | 1:1 (subject to table rules) | £0.10 to £1,000+ depending on operator and table |
| Live streamed (format varies) | Physical wheel or certified automated wheel | Single or double depending on variant | Table rules announced onscreen; check la partage/en prison | Typically same bets as brick‑and‑mortar tables | 35:1 | 1:1 | Often higher minimums (e.g. £1 to £5,000), check provider |
Notes on the table: payout ratios shown are the standard conventional ratios used across roulette tables; specific table rules, limit ranges and availability of la partage/en prison vary by operator and by individual table. Always consult the table rules and the operator’s published terms before wagering.
Why betting systems do not change the house edge
Many players are familiar with named betting progressions (for example flat betting, positive or negative progressions). Betting systems change how you size individual wagers over a session but do not alter the underlying mathematical expectation of each independent spin. Key points:
- The roulette wheel and payout schedule determine the expected return per spin. A betting system redistributes stake amounts across spins but does not change the payout ratios or the wheel composition.
- Independence of spins: each spin is an independent random event (there is no memory in a fair wheel), so prior outcomes do not change the probability distribution for the next spin.
- Bankroll and limit constraints: progressions that increase stakes after losses can exhaust a player’s bankroll or hit table maximums, preventing the theoretical recovery that such systems assume. In practice, these limits impose real constraints that can increase the probability of large losses, not eliminate the house advantage.
A straightforward way to think about it is to compare two approaches that use the same total stake across a series of spins: because the same payout ratios and probabilities apply to each underlying bet, the expected net outcome across the series is the same. Betting systems can alter variance (the pattern of wins and losses) but they do not convert an expected negative value into a positive one.

What to check before playing any roulette table
Before staking real money, check the following to understand how a specific table will treat your wagers:
- Table rules: presence of la partage or en prison, minimum/maximum bets, and whether specific bet types are restricted.
- Payout schedule: ensure the table lists numeric payouts for each bet type.
- Licensing and jurisdiction: which regulator issued the operator licence and how that affects complaint routes.
- Live stream or RNG: whether the table is a live physical wheel or an RNG implementation; both can be fair, but validation and certification differ.
- Responsible‑gambling tools: availability of deposit limits, time‑out options and self‑exclusion; if you are in Great Britain, check GAMSTOP coverage.

UKGC, GAMSTOP and safer‑gambling support
Regulatory and support differences matter. GAMSTOP is a free UK‑based self‑exclusion scheme that applies to online gambling businesses licensed to operate in Great Britain; more information is available from GAMSTOP’s official site: About GAMSTOP. The UK Gambling Commission publishes a public register where you can confirm whether an operator holds a UK licence: UKGC public register.
If you are in Great Britain and are registered on GAMSTOP, attempting to access gambling via non‑GAMSTOP sites can expose you to providers outside the UK regulatory framework, which means different dispute, complaint and consumer‑protection mechanisms. The UKGC has also published analysis and research on unlicensed gambling markets; see their research for context: UKGC unlicensed‑market research.
If you are concerned about gambling behaviour, support organisations such as GambleAware provide help and signposting: GambleAware — get help. If you have self‑excluded, re‑entering gambling via sites that are outside your self‑exclusion reduces the effectiveness of that tool and is not recommended.
Frequently asked questions
What is the main difference between European, French and American roulette?
In brief: European and French roulette normally use a single zero; American roulette has an additional double zero (0 and 00). French roulette commonly offers special treatments for even‑money bets (la partage or en prison) which affect the handling of stakes when the ball lands on zero. These structural differences change the statistical frequency of winning outcomes for some bets and therefore the long‑run expectation, so table rules and wheel composition should be checked before playing.
Why does a double‑zero wheel change the long‑run house edge?
A double‑zero wheel increases the number of losing pockets relative to the number of winning pockets for bets that lose on zero outcomes. Because the payout ratios are typically unchanged (for example straight‑up remains 35:1), the additional losing pocket reduces the expected return to the player per spin. That effect is a consequence of wheel composition and payout schedule, not of how a player sizes wagers.
What do la partage and en prison mean?
La partage and en prison are rule options usually applied to qualifying even‑money bets. With la partage, an even‑money bet that loses because of a zero results in half the stake being returned and half being lost. With en prison, the stake is retained for the next spin (imprisoned); if the imprisoned bet wins on the next spin the stake is returned without additional winnings, and if it loses the stake is forfeited. These rules reduce the immediate loss arising from a zero on qualifying bets, but they apply only where explicitly offered.
Can a roulette betting system change the wheel’s mathematical edge?
No. Betting systems alter stake sizing and variance across sessions but do not change the underlying payout ratios or wheel probabilities. Because each spin is an independent random event and the payout schedule remains the same, the expected return per unit wagered does not change with betting progressions. Betting systems cannot turn an expected negative‑value game into a positive‑value one.
What should a GAMSTOP registrant do instead of seeking another gambling site?
If you are registered with GAMSTOP or have active self‑exclusion, the recommended action is to respect that exclusion and seek support rather than attempting to find alternative sites. Use support services such as GambleAware (GambleAware) for guidance, and consider contacting your GAMSTOP provider for assistance. Trying to bypass self‑exclusion by signing up elsewhere undermines the protections you put in place and can worsen gambling harm.
