The Wheel Variants That Change the Rules

Roulette rules depend first on the wheel in use. European, American and French roulette may share the familiar spinning wheel and ball, but their pockets and zero-related rules are not interchangeable. That distinction matters before any bet is assessed: the wheel determines which outcomes are possible, while the variant’s rules determine whether a zero affects a qualifying wager differently.

European roulette: one zero

A European wheel contains 37 pockets: numbered pockets from 1 to 36 and a single zero. The zero is the feature that separates it from a wheel with an extra zero pocket. It is not an ordinary red or black number, nor does it belong to the even or odd outcomes. Its presence affects the calculation of the game’s house edge, which is 2.70%.

The pocket arrangement around the wheel is also distinct from the betting layout printed on the table. The wheel presents numbers in a fixed sequence around its rim; the table groups numbers into rows and columns for placing bets. Those are two different arrangements of the same numbered outcomes. This difference becomes relevant when a game names bets by neighbouring wheel positions rather than by table groupings, but the central point here is simpler: the wheel variant identifies the set of possible results.

A single-zero European wheel is a useful reference point for comparing the other formats. Its pocket count is lower than that of American roulette, and it does not have the French rules that can alter the settlement of some bets when zero appears. The wheel alone therefore tells part of the story, not all of it.

American roulette: an additional zero

American roulette has 38 pockets. Alongside the single zero found on a European wheel, it includes a double zero. That extra pocket changes the possible outcomes and raises the house edge to 5.26%.

The double zero is not a second label for the ordinary zero. It is a separate pocket on the wheel, so the two zero outcomes must be treated as distinct results. A description of a game as American roulette therefore signals a double-zero wheel, unless the table’s stated rules specify otherwise. Assuming that every roulette wheel has the European arrangement would lead to the wrong understanding of what can land.

The added pocket also means that European and American roulette cannot be treated as identical games with different graphics. The outcomes available on the wheel differ, and that difference is reflected in the house edge. The figures are properties of the respective standard formats, not a prediction of what any individual spin or playing session will produce.

Some versions of American roulette may attach a special settlement rule to even-money bets when a zero appears, but that is not part of the standard definition of the American wheel. The wheel’s double-zero structure and any additional table rule should be kept separate: one describes the possible pockets, the other describes how a particular bet may be handled.

French roulette: the single-zero wheel with extra rules

French roulette uses a single-zero wheel, like European roulette, but adds rules associated with the French format. La Partage and En Prison are the key examples. They concern eligible even-money outside bets when zero lands; they do not change the wheel’s pocket count. La Partage is exclusive to French roulette.

That distinction prevents a common mix-up. European and French roulette can look alike at the wheel level because both have one zero, yet their rules need not produce the same settlement for a qualifying bet. The French variant is identified not by an extra pocket, but by the special treatment available under its rules. Whether either rule applies is a table condition, so the game’s label and displayed rules both matter.

The names of these rules describe different ways an eligible bet can be handled after zero. La Partage returns part of the stake, while En Prison holds the bet for a subsequent spin. Their precise operation belongs with settlement rules, rather than with the wheel’s physical layout. For the purpose of identifying the variant, the important point is that the French wheel retains the single-zero structure while adding rule options that are not a feature of standard European roulette.

What the variant tells the player

The first check is the number and identity of the zero pockets. A single-zero wheel points to the European or French family; a wheel with both zero and double zero is American roulette. The next check is whether the game lists French rules such as La Partage or En Prison. A single zero by itself does not establish that those rules apply.

These distinctions are the foundation of basic roulette rules: the variant establishes the possible wheel results and any special zero treatment before a bet is considered. Similar-looking interfaces do not make the formats equivalent. The pocket count, zero arrangement and stated rules determine which game is being played—and which calculations apply later.

New Zealand’s Online Casino Framework and the Cost of Bonuses

New Zealand’s online casino framework is changing during 2026. The Online Casino Gambling Act 2026 took effect on 1 May 2026, creating the country’s first domestic licensing system for online casino gambling. The Department of Internal Affairs (DIA) is the primary gambling regulator and oversees this framework. The Gambling Commission handles casino licensing applications, decides whether to grant them, issues online casino licences and approves changes to licence conditions. These are separate functions: the DIA oversees regulation, while the Commission determines licensing matters.

The new system is being introduced in stages. Providers that were already serving New Zealand customers before 1 May 2026 may continue operating during the transition, subject to the Act’s transitional provisions. That permission runs until 1 December 2026. Providers that have not applied for a licence must stop conducting online casino gambling in New Zealand by that date. The full licensed regime is not expected to be operational until 2027, and unlicensed operation is expected to become an offence around mid-2027. Providers without a licence may face enforcement action and fines of up to NZ$5 million.

The transition should not be confused with the earlier position. The Gambling Act 2003 does not permit online casinos to be based in New Zealand. Before the 2026 Act, offshore online casino gambling had no New Zealand licensing or supervisory framework, and customers wagering with offshore websites had no domestic government recourse. The new law establishes a route to domestic licensing; it does not make every online casino available to New Zealand customers licensed. During the transition, licensed operators must use stricter age and identity checks.

A bonus is a set of conditions, not a cash balance

A casino bonus can increase the displayed balance without increasing the amount immediately available to withdraw. Its value depends on the conditions attached to it: eligibility, wagering requirements, expiry, which games contribute, and withdrawal restrictions. A headline offer does not show the final withdrawable amount unless those terms are included in the calculation.

For bonus money, the required wagering is 50 times the bonus amount within 30 days. If the bonus is NZ$20, for instance, the wagering requirement is NZ$1,000 before the bonus-related condition is met. That total is wagering turnover, not a sum paid back to the account. The funds are exposed to losses while the requirement is being completed, so the face value of a bonus is not equivalent to cash.

Free spins have a separate condition: winnings from them must be wagered 50 times within 7 days. The requirement applies to the winnings, rather than being a promise that the full amount will remain available after play. Expiry matters as well. If a requirement is not completed within its stated period, the offer’s terms determine what happens to the bonus or related winnings.

A withdrawal request has a direct consequence: it voids all active or pending bonuses. This means requesting payment before completing a bonus condition can remove the bonus and any associated value covered by its terms. The relevant comparison is therefore not simply the advertised bonus against a deposit. It is the amount that remains withdrawable after wagering, expiry and withdrawal rules are applied.

Game contribution can further affect the calculation. If a game contributes only part of each wager towards a requirement, the amount played may not equal the amount credited against it. The terms should be read for the specific offer, including which games count and how much they contribute. A short expiry combined with limited game contribution can make a nominal bonus harder to convert into withdrawable funds.

For New Zealand players comparing online casino terms in 2026, the regulatory status and the bonus calculation are distinct checks. A provider’s position under the transition concerns whether it may operate; bonus terms determine what happens to promotional funds. Neither makes bonus money equivalent to a cash balance. The final amount available for withdrawal depends on the stated conditions and whether they have been met before a withdrawal request is made.

How the Roulette Table and Called Bets Work

A roulette table presents two different ways of organising the same game. The betting layout is the numbered grid printed on the cloth; the wheel arranges those numbers around a circular track. They serve different purposes. The cloth shows where a wager is placed and what group it covers, while the wheel determines the order of pockets for called bets.

Most wagers are placed on the cloth. A chip placed on a number covers that number; a chip placed on a line or marked area covers a group defined by the layout. These are layout bets. Their names describe the position of the chip on the betting grid, not a run of neighbouring pockets around the wheel. That distinction matters because the grid and the wheel are arranged differently.

A straight-up bet is placed on a single number. A split covers two adjoining numbers, with the chip positioned on their dividing line. A street covers a horizontal row, while a corner covers a cluster meeting at one point. A line bet covers neighbouring rows. These terms identify the geometry of the printed layout. The physical placement is the instruction: a chip centred on a number is not the same wager as one set on a boundary.

The layout also groups numbers into broader sections, including columns, dozens, red or black, and odd or even. Those areas can make selection easier to read, but they remain cloth-defined groups. They do not indicate that the selected numbers sit next to one another on the wheel. A set can be close together on the grid and scattered around the circular track.

Called bets reverse the point of reference. They are organised around number positions on the wheel, not around the rows and columns printed on the table. A caller may name a wheel sector or a named group of pockets, and the dealer then places the relevant chips on the layout. The resulting chips can occupy several separate points on the cloth. Their separation does not make the call inconsistent: the group is contiguous or defined by its relationship on the wheel, rather than by its appearance on the grid.

Some familiar names for these calls include Voisins du Zéro, Tiers du Cylindre and Orphelins. The names refer to wheel-based groupings, so they should not be read as ordinary layout labels. A called bet is not a special pocket, nor does its name describe a single location on the cloth. It is a request to cover a specified set of wheel positions using the corresponding placements on the table.

The practical sequence is therefore straightforward. First, the bet is identified by its basis: a layout group or a wheel-based call. Then the chips are positioned on the cloth to represent that choice. For a called bet, the dealer translates the named wheel grouping into the appropriate layout placements. The cloth remains the betting interface even when the selection itself comes from the wheel.

This separation also explains why a table’s visual pattern can mislead. A cluster of chips may look like a connected shape on the grid, but that does not establish that the selected pockets are adjacent around the wheel. Conversely, a wheel sector may require chips placed at dispersed points on the cloth. The placement records the wager; the wheel relationship defines the called group.

Before a spin, the useful check is whether the intended selection has been represented correctly on the layout. For an individual number or a standard layout group, the chip position communicates the choice directly. For a called bet, the name and its wheel-based definition matter; the chip pattern may not resemble the sector it covers. Confusing those two systems can leave a wager on a different group from the one intended.

Roulette Odds: House Edge and Return Percentages

House edge and payout percentage describe the same long-run relationship from opposite sides. The house edge is the portion of stakes the game is mathematically set to retain over time; the payout percentage is the corresponding share returned to players. Neither figure predicts the result of an individual spin or determines what a particular session will return.

On standard European Roulette, the single-zero wheel gives the game a house edge of 2.70%. The corresponding theoretical payout is 97.30%. These figures are two expressions of the same calculation, not separate advantages that can be added together. A return percentage is not a promise that a player will receive that share back during a short session: actual results can fall above or below it.

A specialist review reports payout figures of 97.30% for European Roulette and 94.70% for American Roulette. The first aligns with the single-zero game’s stated edge. The second is relevant as a comparison, but the wheel and its effect are treated separately in the discussion of double-zero roulette. Published payout figures should therefore be read alongside the roulette format and the rule conditions attached to a table, rather than as a universal rate for every game carrying the roulette name.

French Roulette uses the same single-zero layout as European Roulette, but its special rules alter the cost of eligible bets when zero appears. Where La Partage or En Prison applies, the house edge on the relevant even-money bets falls to 1.35%. That is half the standard single-zero edge. The difference comes from the treatment of qualifying stakes after zero, not from a different pocket layout or a better result on every spin.

The 1.35% figure is conditional: it applies when the French rule is available and the bet qualifies. It should not be treated as the edge for every wager on a French table. Bets outside the eligible category do not receive that reduction, so a general label such as “French Roulette” is not enough to establish the cost of every bet. The table’s stated rule and the type of wager both matter to the calculation.

For eligible even-money bets, French Roulette offers the lower stated house edge among these formats because La Partage and En Prison soften the effect of zero. The practical settlement of those rules is a separate matter; mathematically, the key point is that the reduction is limited to qualifying bets and depends on the rule being in force. Without that condition, the standard single-zero comparison remains 2.70%.

A useful comparison keeps three items distinct: the game’s wheel format, the house edge applicable to the wager, and any payout percentage quoted by a review or operator. The European figures of 2.70% edge and 97.30% return correspond. The French figure of 1.35% applies to eligible even-money bets under the specified zero rules. These are theoretical measures of game cost, not a forecast of a player’s final balance.

Double-Zero Roulette and the American Wheel

American roulette uses a wheel with 38 pockets: numbered pockets from 1 to 36, plus a single-zero pocket marked 0 and a double-zero pocket marked 00. The two zeroes are separate outcomes. A bet on 0 is not a bet on 00, and neither pocket should be treated as a substitute for the other when reading a result.

The layout matters because the wheel, not the betting grid, determines which pocket the ball lands in. The table gives places to set bets; the wheel’s pockets determine the winning result. In a double-zero game, both zero pockets are part of the wheel’s outcome set. A rule that refers to zero may also specify double zero, so the wording matters.

The basic sequence is straightforward: bets are placed before the spin, the ball lands in a pocket, and the result is settled according to the marked outcome and the table’s stated terms. The presence of 00 does not create a second kind of spin or a separate settlement procedure by itself. It adds another pocket to the set of possible results. The exact treatment of a bet when either zero appears depends on the rules attached to that table.

A half-stake return on even-money bets is not an automatic feature of American roulette. A specialist review reports that some Atlantic City tables return half the stake on those bets when either 0 or 00 lands. That is a limited table rule, not a general rule for every American wheel. The review’s statement should not be read as evidence that this condition is available at all Atlantic City tables, or at every online version labelled American roulette. The stated table terms remain decisive.

This distinction also separates the feature from French roulette. La Partage is exclusive to French roulette; it is not the name for a half-stake return attached to American roulette. A similar-looking result does not make the rules interchangeable. The table may offer a specific zero-related condition, but its scope needs to be read as written: which bets it covers and whether it names 0, 00, or both.

For anyone comparing games, the useful check is the rules panel for the exact table rather than the game title alone. “American roulette” identifies the double-zero format, but does not promise a half-stake return. If no such condition is stated, the presence of two zero pockets should not be mistaken for protection on an even-money bet. Every real-money bet can lose, and no roulette label changes that basic exposure. Stakes should remain within money that can be lost without affecting essential expenses.

Even-Money Bets When Zero Lands

An even-money outside bet is treated differently if the ball lands on zero and the table applies La Partage or En Prison. These rules affect only eligible even-money outside bets; they do not change the settlement of other wagers. The table’s stated rule matters: zero does not automatically trigger either procedure wherever roulette is played.

La Partage: half the stake returned

With La Partage, zero causes the dealer to return half the stake on an eligible even-money bet. The other half is collected. The wager is settled at that point; it does not remain active for another spin.

For instance, a stake on red that meets zero under La Partage is neither paid as a winning bet nor collected in full. Half comes back, and half is lost. The same treatment applies to other eligible even-money outside bets, such as black, odd, even, high or low, provided the table applies the rule.

La Partage is exclusive to French roulette. A French table offering this rule can therefore settle a zero result differently from a table without it. The reduction in loss applies to that particular eligible bet when zero lands; it does not mean every bet receives half its stake back, or that a losing result on a later spin is protected.

En Prison: the stake stays in play

En Prison handles zero by carrying an eligible even-money outside bet forward rather than returning part of the stake immediately. The bet is held for the following spin, so the original stake has not yet been settled.

If that next spin is a win for the imprisoned bet, the original stake is returned, but no additional winnings are paid. If the next spin is a loss, the stake is collected. The result is therefore not a normal win at even-money odds: a successful follow-up returns the amount committed, rather than adding a profit.

The distinction is practical. Under La Partage, the zero result produces an immediate partial return and a partial loss. Under En Prison, the stake remains unresolved until the next spin, when it is either returned or collected according to the outcome. A bet carried forward should not be counted as available funds while its settlement is pending.

Both procedures are narrow exceptions to the ordinary handling of a losing even-money bet. They apply only when zero lands and only to the specified class of outside wagers. They do not extend to straight-up number bets or other bet types simply because those wagers were placed on the same spin.

Table wording should be checked before a bet is placed: the presence of a French-style wheel does not, by itself, establish which zero rule is in force. La Partage and En Prison have different settlement consequences, and the difference is material to the amount returned and the time at which the stake is resolved.

Roulette remains random, and every real-money bet can lose. Neither rule removes that risk; La Partage limits the loss on an eligible zero result, while En Prison leaves the stake exposed to the next spin. Stakes should remain within amounts that can be lost without affecting essential spending.

Mini Roulette’s Smaller Wheel, Different Edge

Mini Roulette compresses the game into a wheel with 13 pockets. That smaller field can look like a simpler route to a result, but pocket count alone does not establish better value. The relevant comparison is the cost built into the game: Mini Roulette carries a house edge of 7.89% under its standard rules.

La Partage changes that figure to 3.85%. The reduction applies where the rule is offered and concerns eligible even-money outside bets when zero lands; it does not turn every wager on the table into a lower-edge bet. The rule changes how a specific class of bet is settled, not the underlying pocket count.

The figures show why “fewer pockets” is not a useful measure of value by itself. Mini Roulette’s standard edge is higher than its edge when La Partage applies, but the lower figure depends on both the rule and the bet being eligible. A table labelled Mini Roulette should therefore be assessed by its stated settlement terms as well as its wheel format. The name does not disclose whether La Partage is included.

This distinction matters when comparing roulette game rules. A reduced wheel can still carry a less favourable edge, while a special zero rule can lower the cost for a limited set of wagers. Neither fact should be treated as a blanket improvement to every bet available.

For a clear comparison, the table information needs to establish whether La Partage applies and which bets qualify. Without that condition, the standard 7.89% edge is the relevant figure; with it, the stated edge for eligible play is 3.85%. The difference is material, but it is conditional rather than automatic. A smaller wheel is a format description, not a promise of better returns.

Minimum Bets: Check the Table Terms Before Betting

A roulette minimum is a condition attached to a particular table, not a figure that can safely be assumed across every game. The amount required to place a bet may differ between tables, including tables offering the same roulette format. The practical rule is to identify the minimum shown for the selected table before staking money.

The minimum determines whether a bet can be entered at all. A stake below that threshold will not qualify, while a stake that meets it satisfies only the entry condition; it says nothing about the chance of winning or the amount returned. Those are separate questions from the cost of placing a bet.

The displayed terms should also be read in context. A table may set conditions for the minimum stake, while the betting interface shows the amount selected for a particular wager. Those figures serve different purposes: one sets the entry threshold, the other records the intended stake. Confusing them can produce a rejected bet or a larger commitment than intended.

For online play, the table’s own information is the relevant reference point. A minimum seen on one game should not be carried over to another table, even when the games appear similar. The amount can be checked again whenever the table changes; assumptions based on a previous selection do not establish the terms of the next one.

Minimums matter most when setting a session budget. If the required stake does not fit the amount allocated for play, that table is outside the budget, regardless of its appearance or format. A lower minimum can allow smaller stakes, but it does not improve the game’s underlying terms or make a losing result less possible. Roulette outcomes remain random, and every real-money bet can lose.

The useful comparison is therefore straightforward: confirm the minimum for the chosen table, compare it with the intended stake and the amount set aside, and proceed only if both align. No roulette minimum makes a bet safe. Money that cannot be afforded as a loss should not be placed on the table.

Payout Percentages Across Roulette Formats

A payout percentage describes the theoretical share of stakes returned over extensive play, not the amount guaranteed back during a particular session. It is a comparison measure: an individual result can be far above or below it, and every real-money bet can lose.

For standard formats, the stated figures are 97.30% for European Roulette and 94.70% for American Roulette. These returns reflect the different wheel layouts and their effect on the game’s long-run cost. The percentage does not change the settlement of a particular winning bet; it summarises expected returns across repeated play.

A specialist review gives a payout range of 92.86% to 96.19% for 100/1 roulette. That range is specific to the format as reported in the review, rather than a universal figure for every game carrying the name. The gap between its lower and upper figures is material when comparing published return information. The game’s displayed rules and payout table remain the relevant terms for a particular version.

These figures should not be read as a forecast for a deposit, a session or a sequence of spins. A payout percentage is not a promise that the same share will be returned over a short period, nor does it set a ceiling on losses. Random outcomes can produce a result that differs sharply from the theoretical return.

The practical comparison is therefore limited but useful: the published percentages show how formats differ in their long-run return calculations, while the game rules determine how individual bets are settled. A higher stated return does not make a winning result certain, and a lower one does not specify when a loss will occur. The percentage is a measure of the game’s structure, not a personal outcome.

Roulette Strategy Cannot Change the Next Spin

Roulette rules and strategy determine how a bet is placed and what happens if it wins, but they cannot make a particular result more likely on the next spin. Each spin is independent: the sequence already recorded on the wheel does not alter the probabilities of future outcomes. A run of one colour, number or section is not evidence that the wheel is due to produce something else.

Betting systems change the pattern of stakes, not the mechanism producing the result. Increasing a stake after a loss can make a later win worth more, but it also means more money is exposed while the losses continue. Reducing a stake after a win does not protect the next bet from losing. No progression, staking schedule or selection based on previous results removes the house edge.

That distinction matters when a system is described as a way to recover losses. Recovery is conditional on having enough money to continue, on remaining within the table’s limits, and on a later winning result occurring before play stops. None of those conditions changes the probability of that result. A spreadsheet can organise the stakes; it cannot negotiate with the wheel.

The rules can still affect which eligible bets have the least unfavourable terms. French Roulette offers the best odds for even-money bets because La Partage and En Prison change how those bets are treated when zero lands. That is a rule-based difference, not a strategy that predicts outcomes or turns a losing proposition into a guaranteed return.

A sound decision is therefore about the amount at risk and the point at which play ends, not about finding a sequence that forces a result. Roulette outcomes are random, and every real-money bet can lose. Money set aside for essential expenses is not a bankroll, whatever staking plan is written beside it. The amount at risk should never exceed what can be afforded to lose. If the only way to continue is to raise stakes, borrow, or chase earlier losses, the decision has already moved beyond calculation.
