Single zero
European roulette has one zero; American roulette adds a second zero pocket.
snake · European roulette
European roulette uses numbers 1–36 and one zero. snake explains the wheel, common bet groupings and the differences from French and American roulette so the variant name has practical meaning.
One wheel, several ways to describe a bet
The standard European wheel has 37 pockets: numbers 1–36 and a single zero. The zero matters because it is not an ordinary red or black number. An even-money label should not be mistaken for a fifty-fifty chance.
Inside bets cover individual numbers or small neighbouring groups on the layout. Outside bets cover broader sets such as a colour or a numbered range. Broader coverage and a higher payout are different concepts; neither removes the house advantage.
American roulette includes both 0 and 00. French roulette shares the single-zero wheel but can apply La Partage to even-money bets when zero occurs. Do not assume that rule applies to every European table.
A simple result example
If a valid straight-up selection covers 17, only a result of 17 matches that selection. A red selection instead depends on the result’s colour, while a zero result is outside red and black. This example illustrates coverage rather than a strategy.
A history panel records previous rounds. It does not make the next independent result due to reverse a streak. Increasing a stake after losses can quickly exhaust a finite budget and does not remove the underlying disadvantage.
Recognise the important distinctions
Taken together, these details distinguish the conditions and practical needs involved in european roulette.
Coverage
A number selection and a colour selection cover different sets of outcomes.
Special rules
French La Partage must be stated by the ruleset; it is not inferred from the wheel alone.

European roulette: questions answered
Is zero red or black?
No. It is a separate pocket and is not included in a red or black selection.
Does a long red streak make black due?
No. Previous independent results do not force the next colour.
Is La Partage universal?
No. The French ruleset described by the maker applies it to even-money bets on zero; check the actual table.
Does doubling after losses ensure recovery?
No. Budget and table limits can stop the sequence, and increasing stakes does not eliminate risk.
