Single versus double zero
European and American outcome sets differ. Match the wheel name to its zero layout.
Roulette: wheels, numbers and zeros
European and American roulette use different wheels. Understand number selections, zeros and variant conditions.
The pocket where the ball rests
The pocket holding the ball determines the roulette number. The table layout provides selections for a number or groups of numbers. Wheel order differs from table order.
A European wheel has one to thirty-six and a single zero. An American wheel adds a double zero. This changes the set of possible outcomes.
Colour, parity and number groups cover several outcomes; a straight number covers one. Broader coverage does not eliminate risk. Keep the role of zero in view.
Differences that names can hide
Special presentation does not replace the need to read the exact variant’s rules.
French La Partage
Some French formats apply a half-loss rule to defined even-money bets on zero. Do not assume it applies to every roulette.
Dealer-led or automated
A physical wheel can operate without a dealer. The absence of a visible person alone does not establish another result method.
Seeing the wheel versus predicting a result
A casino wheel is the subject of the illustration. Understanding an actual round requires its complete action and recorded result. A still image is not evidence of a current outcome.
A result history can show a long colour sequence. That does not create a rule requiring the opposite colour next. History is not a future guarantee.
