Fairplay Roulette: Rules, Wheel Types and Probability

Fairplay Roulette is best understood as a rules-and-probability topic: a wheel, a ball, numbered pockets, and a settlement table determine what each selection means. This guide explains the standard game format without presenting an operator relationship, licence, or access route. The branding in the heading is supplied for this page; it should not be read as a claim that a named service is official or licensed.

What roulette is

Roulette is a wheel game in which a croupier spins a ball around a rotating wheel. After the call that no more selections may be made, the ball falls into one pocket. A result is the pocket itself, such as 17 or 0; colour and number groups are derived from that result. The wheel outcome is random for each spin, so a run of red results does not make black “due”. [MGM’s neutral game guide][S1] describes the same separation between inside selections, outside selections, and random spins.

A useful distinction is selection versus payout. A straight selection names one number and normally returns 35 to 1 in the standard table. A red-or-black selection covers a larger group and normally returns 1 to 1. The return is not the chance: a higher quoted return corresponds to a narrower set of winning pockets, while a broad selection wins more often but pays less.

Wheel formats and pocket counts

European roulette

A European wheel has 37 pockets: numbers 1 through 36 and one zero. A straight selection on one number therefore has a one-in-37 chance of landing on that number. The zero is a pocket, not an odd, even, red, black, high, or low number. On the usual even-money table, a red-or-black selection covers 18 pockets, giving 18/37 probability before any other table rule is considered.

American roulette

An American wheel has 38 pockets: 1 through 36, zero, and double zero. A straight selection has a one-in-38 chance. Double zero is not included in ordinary red/black, odd/even, or high/low groups. A common American layout also has a five-number top-line selection covering 0, 00, 1, 2, and 3, normally quoted at 6 to 1. Exact menus can vary by jurisdiction or house rules, so the displayed rule sheet controls.

A worked probability comparison

Consider a hypothetical one-unit straight selection, used only to show arithmetic. On a European wheel, the chance of the named number is 1 ÷ 37 = 2.7027%, and the chance of missing is 36 ÷ 37 = 97.2973%. On an American wheel, those figures are 1 ÷ 38 = 2.6316% and 37 ÷ 38 = 97.3684%. The nominal 35-to-1 payout is the same in this standard example, but the extra pocket changes the probability. No sequence-based method removes that structural difference.

Common selections and settlement terms

Roulette terminology is easier to read when the table is grouped by coverage:

• Inside selections: straight (one number), split (two adjacent numbers), street (three), corner (four), and six line (six). The standard published returns are 35 to 1, 17 to 1, 11 to 1, 8 to 1, and 5 to 1 respectively.
• Outside selections: red or black, odd or even, high (19–36) or low (1–18), dozens, and columns. Standard returns are 1 to 1 for the even-money groups and 2 to 1 for a dozen or column.
• Zero treatment: zero and double zero are separate pockets. They do not count as odd/even or red/black in the standard layout. Some tables apply special rules to particular even-money selections; those rules must be read rather than assumed.

“35 to 1” usually means a net win of 35 units plus the original one-unit stake returned, if the table uses conventional terminology. A one-unit selection that wins would therefore produce 36 units in total, while a loss would forfeit the one unit. This defines payout language, not an outcome promise.

Variations and uncertainty

The main variation is the wheel: single-zero European, double-zero American, and less common layouts with different pockets or rules. A table can also alter the treatment of zero, the set of available selections, minimum or maximum limits, or the wording used for returns. Live, electronic, and automated formats may differ in presentation, but presentation does not by itself prove a different probability model. Record pocket count, eligible selections, payout schedule, zero rule, and any stated randomisation method.

A mathematical expectation can clarify why payout tables matter. For a one-unit straight selection with a 35-to-1 net return, the hypothetical expected net result on a European wheel is (1/37 × 35) − (36/37 × 1) = −2/37, about −0.0541 unit per unit selected. On an American wheel it is (1/38 × 35) − (37/38 × 1) = −2/38, about −0.0526. These are long-run averages for the stated model, not predictions for a short series and not a guarantee of loss on any individual spin.

Frequently asked questions

Is European roulette the same as American roulette?

No. European roulette normally has 37 pockets and one zero; American roulette normally has 38 pockets because it adds double zero. That changes the probability of every number and group selection, even when the displayed payout is unchanged.

Does a previous colour affect the next spin?

No, assuming a properly functioning random wheel and the stated rules. Each spin is a new event. A sequence can look unusual without creating a compensating obligation on the next result.

What should be checked before comparing two rule sheets?

Check pocket count, zero or double-zero treatment, eligible selections, quoted returns, special zero rules, and any jurisdiction-specific playing conditions. Missing items make the comparison incomplete.

Can roulette rules explain a cricket forecast?

No. Roulette rules describe a wheel event and settlement table. Cricket analysis uses match data and Laws-based context. They can be discussed on the same educational page, but their evidence, timescales, and sources should remain separate.
