Roulette Odds Calculator

Historical Background

Roulette is a classic casino game that has been around since the 18th century, originating in France. The game’s name means “little wheel” in French, and it involves players betting on the outcome of a ball spinning around a wheel. The wheel is divided into numbered pockets (1–36, with a 0 in European Roulette, and an additional 00 in American Roulette). Players bet on individual numbers, groups of numbers, or color combinations, making it a blend of luck and strategy.

Calculation Formula

The probability of winning a roulette bet depends on the type of bet. The basic formula for calculating winning probability for any bet type is:

\[ \text{Winning Probability} = \frac{\text{Number of Winning Outcomes}}{\text{Total Number of Outcomes}} \]

In European Roulette, there are 37 outcomes (1–36 and 0). In American Roulette, there are 38 outcomes (1–36, 0, and 00). For example, a straight bet on a single number has 1 possible winning outcome out of 37, so:

\[ \text{Probability of a Straight Bet} = \frac{1}{37} \times 100 = 2.7\% \]

To calculate the payout, multiply the bet amount by the specific bet’s payout ratio. For a straight bet (payout 35:1):

\[ \text{Potential Payout} = \text{Bet Amount} \times 35 \]

Example Calculation

Suppose you place a $100 straight bet on a single number. The probability of winning is:

\[ \frac{1}{37} \times 100 = 2.7\% \]

If you win, the payout will be:

\[ 100 \times 35 = 3500 \text{ dollars} \]
