European Roulette Wheel

The numbers on a single-zero (European) Roulette wheel and their associated properties: colour, betting categories and the traditional sectors of the wheel. Each row represents one of the 37 numbers (0–36).

Usage

Roulette

Format

A data frame with 37 rows and 7 variables:

num

integer, the number in the pocket (0–36).

col

factor, colour of the pocket: red, black or green.

parity

factor, even or odd.

highlow

factor, low (1–18) or high (19–36).

dozens

factor, dozen on the table: 1 (1–12), 2 (13–24), 3 (25–36).

column

factor, column on the table: 1, 2 or 3, counted from the one containing 1.

pocketrange

factor, sector of the wheel: jeu zero, voisins du zero, tiers du cylindre or orphelins.

Source

The standard layout of a single-zero Roulette wheel.

Details

The dataset can be used for teaching probability and categorical data analysis, as well as for simulating Roulette betting strategies.

The rows are ordered as the pockets follow each other on the wheel, starting at zero, and not by num. The sectors in pocketrange are therefore contiguous blocks of rows.

Zero takes part in none of the even/odd, high/low, dozen and column bets, so these variables are NA for zero. Note that this follows the rules of the game and not arithmetic, where zero would count as even.

The seven numbers of the jeu zero are part of the voisins du zero in the usual reading of the terms. As every number appears exactly once here, they are reported as a separate level and voisins du zero covers the remaining ten numbers of that sector.

Accents are dropped in the factor levels (voisins du zero for voisins du zéro).
