The Play

A female player places chips on number 27 in a game of European roulette.

Whether online or in-person, roulette starts with players placing their bets on the layout. They can stake on particular numbers and groups of numbers.

The croupier (dealer) spins the wheel and flings a small ball. The ball’s final position determines the winning color, number, or group.  


Roulette’s popularity is primarily due to the many betting options it offers. Still, standard roulette rules for various types of bets apply to any modern roulette version, including online roulette.

Outside Bets

The roulette wheel’s outer section offers gamblers better odds of winning than the inside.

The chance that a ball will hit the outside section (red/black, even/odd, or low/high) is 47.37%. Outside bets typically have even-money (1:1) roulette payouts. 

For instance, a $100 bet with even-money odds could give you a $100 payout if the number hits, making your total payout $200.

$100 x 1 = $100 (profit or winning)

Original bet + Profit = Total Payout

$100 + $100 = $200

Inside Bets

You place these bets on particular numbers and combinations of numbers on the betting table's inner section. Betting on inside numbers is riskier because they have a low chance of winning. Still, these inside bets could yield a more considerable payout.  

The Worst Bet

Different sources consistently mention that straight up bets and five-number bets are some of the worst. 

Straight up bet involves the numbers 1 to 36 plus the zeroes (the single zero and double zeroes in the American roulette version). This means a 1-in-37 chance of predicting the winning number in American roulette. You should avoid this bet due to your low chance of winning. 

The five-number bet (top line bet) might have the worst roulette odds, with 13.2% odds and a meager 6:1 payout. 

Despite what the sources say, ultimately, the worst bet is the one where you’re most likely to lose money.

What Is The Best Bet Roulette Bet?

European roulette’s odds are better than American roulette since the European roulette wheel has a single zero pocket instead of two. Consequently, stakes placed on European roulette can be the best betting opportunities for players.

Roulette Game Strategy

The trick to winning roulette games and minimizing losing bets is to select the best odds

One option is to place even-money bets and single-number or straight-up bets, like: 

  • Red or black

  • High or low

  • Even or odd

Though these roulette bets have lower odds and lower payouts, the risk of losing them is low, too. Other factors to consider when betting on roulette: 

House Odds

Roulette has many variants and, consequently, different house edge percentages. House edge (juice) refers to the casino’s margin or what the casino expects to profit from every game. 

It’s important to use a gambling platform like, which prioritizes the bettor experience by offering promotions like reduced house edge.


Many people, particularly mathematicians, have devised betting systems they think can beat the roulette wheel. Overall, these systems revolve around even-money bets.

For instance, French mathematician Paul Pierre Levy’s Martingale strategy is founded on the idea that, in case of a loss, you should immediately double the size of the next bet until you eventually even out with a win.

It’s best to use the Martingale strategy for outside bets, including:

  • Red or black

  • Odd or even 

  • High or low

Another strategy is the progressive betting tactic, where you adjust your stake amount depending on whether your last bet was won or lost. 

Roulette Odds And Payouts

In roulette, as in any other gambling game, the odds tell players their potential payout or how much money they can win.

Types of Roulette And Table Layout

A standard roulette wheel has a spinning disk surrounded by pockets. Wheel sizes and prices vary depending on the features.

The game begins when the dealer rolls a ball, and it lands on one of the numbered spaces (pockets). The players must guess the ball’s final position.

Each pocket is numbered 1 to 36 in an alternate red and black pattern. 

Zero (0) is the only green spot on a conventional roulette wheel. It’s also the number that spells the difference between European and American roulette wheels. 

The European wheel features a single zero pocket, while the American version has a double-zero slot (00).  

Before the croupier spins the wheel, players place chips on the mat to bet which number will "hit."

American Roulette Wheel

American roulette is among the most widely played roulette games. Since the wheel has an additional double-zero pocket, it’s harder to win than the European version. 

European Roulette Wheel

European roulette, just like French roulette, provides better odds than American roulette. The wheel only has a single zero pocket, making European roulette easier to win than its American counterpart.


Roulette’s gameplay is generally the same, whether online or in casinos. But the items for online roulette are not the same as physical roulette equipment. Digital roulette includes the following:
