The roulette wheels used in the casinos of Paris in the late 1790s had red for the single zero and black for the double zero. To avoid confusion, the color green was selected for the zeros in roulette wheels starting in the 1800s.

## Rules of play against a casino

Roulette players have a variety of betting options. “Inside” bets involve selecting either the exact number on which the ball will land, or a small group of numbers adjacent to each other on the layout. “Outside” bets, by contrast, allow players to select a larger group of numbers based on properties such as their color or parity (odd/even). The payout odds for each type of bet are based on its probability

## Types of bets

bets can be either *inside* or *outside*.

**Inside bets:**

Name | Description | Chip placement |
---|---|---|

Straight/single | Bet on a single number | Entirely within the square for the chosen number |

Split | Bet on two vertically/horizontally adjacent numbers (e.g. 14-17 or 8–9) | On the edge shared by the numbers |

Street | Bet on three consecutive numbers in a horizontal line (e.g. 7-8-9) | On the outer edge of the number at either end of the line |

Corner/square | Bet on four numbers that meet at one corner (e.g. 10-11-13-14) | On the common corner |

Six line/double street | Bet on six consecutive numbers that form two horizontal lines (e.g. 31-32-33-34-35-36) | On the outer corner shared by the two leftmost or the two rightmost numbers |

Trio/basket | A three-number bet that involves at least one zero: 0-1-2 (either layout); 0-2-3 (single-zero only); 0-00-2 and 00-2-3 (double-zero only) | On the corner shared by the three chosen numbers |

First four | Bet on 0-1-2-3 (single-zero layout only) | On the outer corner shared by 0-1 or 0-3 |

Top line | Bet on 0-00-1-2-3 (double-zero layout only) | On the outer corner shared by 0-1 or 00-3 |

**Outside bets:**

Outside bets typically have smaller payouts with better odds at winning. Except as noted, all of these bets lose if a zero comes up.

The roulette table is composed of two sections, the wheel itself and the betting layout, better known as the roulette layout. There are two styles of roulette tables. One has a single betting layout with the roulette wheel at one end, and the other has two layouts with the wheel in the centre. The wheel spins horizontally.

The game begins when one of the croupiers (dealers) in attendance calls for the players to make their bets, which they do by placing chips on the spaces of the layout on any number, group, or classification they hope will win.

The croupier usually starts the wheel spinning in a counterclockwise direction and then spins a small ivory or plastic ball onto the bowl’s back track in the opposite direction. Players may continue to place bets while the wheel and ball are in motion until the ball slows down and is about to drop off the back track, at which time one of the croupiers announces that no more bets may be made.

When the ball falls and comes to rest between any two metal partitions of the wheel, it marks the winning number (or a 0 or 00), the winning colour, and any other permitted bet that pertains to a winning number or symbol. The dealer immediately announces the winning number and its colour and places a special marker on the corresponding number on the layout. He first collects all losing bets, not disturbing the chips that are resting on winning spaces, and then pays off any winning bets.
