Roulette is a famous casino game in Vegas, perhaps the most famous, that we have the French to thank for its existence on American shores. The game is played on a “roulette wheel” features a wheel (below) where players put their bets on the ball falling on a single number. Players who play the game Roulette have the option to place bets on either a single number (or multiple numbers), or the colors (red or black), whether the number is odd or even, or if the numbers are high (19–36) or low (1–18).

To determine who is the winner the dealer, often called a croupier, spins a wheel in one direction, then spins a ball in the opposite direction around a tilted circular track running around the outer edge of the wheel. Within about 30 seconds, the ball slows down and falls into one of 38 colored and numbered pockets on the wheel. The winnings are then paid to anyone who has placed a bet on one of the numbers or colors. Here’s what it looks like.

This would be a winning bet on “Green 0.” The common mantra in vegas is to, when first arriving in Las Vegas, place a bet on “Red or Black” to see how the weekend (or however long the trip is) is going to play out. However, notice the ball in this image landed on green to elucidate this point: the odds of Roulette are always less than 50/50 for this very reason. Often considered “the best odds in vegas” a bet on Red or Black is near 50/50 but not EXACTLY 50/50 in order to give Vegas the necessary edge required to justify the game.

In American Roulette, there are TWO green pockets, one labeled 0 and the other labeled 00. This is going to be extremely important later, but important to note now. Before we move any further, note that you have all the information you need to know that there is no way to game the system into positive odds.

Roulette Wheels Can Be Different

Regardless of where you play the game, number ranges in Roulette are from 1 to 10 and 19 to 28, odd numbers are red and even are black. In ranges from 11 to 18 and 29 to 36, odd numbers are black and even are red.

Single-Zero Wheel Numbers

Roulette features single-zero wheel numbers, double-zero wheel numbers and triple-zero roulette numbers. We’ll start with Single-Zero Wheel numbers and list them in a clean format so they can be seen/copied/re-used in group chats all around the world.

Triple-Zero Wheel


However, we’ll stick with the traditional, Roulette Wheel you’re likely to see in Vegas. We know it can be intimidating to walkup to the Roulette wheel (especially for the first time!) so we’ll cover how to place the bet (and what not to do) shortly.

The “Best” Odds In Vegas

It has become common place for tourists from elsewhere to come to Vegas with a plan to put an inordinate amount of money on red or black. This is because the odds of drawing “red or black” seems like it’s 50/50 and so it’s inviting to many tourists unfamiliar with the gambling scene. If you’re not following, in addition to single digit numbers players can put their money on a specific color: red, black or green.

The board is divided “almost” 50/50 into red and black numbers. However, and this is where they get you, there is a green number “0”–and in American Roulette there are TWO green numbers “0” and “00.” This is where Vegas is able to create their advantage. This is precisely where the house odds come in. If you’re playing non-American Roulette the green spaces drop the odds from 50/50 to 47.4%. If you’re in a Las Vegas casino playing American Roulette, the odds are even worse: 46.37%.

Odds of Hitting Individual Number In Roulette

Though there are fascinating stories of gambling glory being achieved during a Vegas trip with spin of a roulette wheel, if you’re betting on an individual number things probably aren’t going very well for you. The odds of hitting an individual number are 37 to 1, but the house only pays out 35 to 1. Now that house edge could be worse (see literally any other article) but, at the end of the day, the odds remain 37 to 1 and only pays out 35 to 1. So if you bet $100 and miraculous hit a number on the nose, you would be paid $350 (you ‘should’ get $370 if the payout represented the odds of hitting a number exactly).
