Understanding Roulette Odds and Probabilities

Roulette is majorly a game of chance. You can’t determine the movement of the Roulette ball once it starts rolling in the Roulette wheel. However, there is a concept that you can grasp to help you. It is called Roulette odds. With a knowledge of what the odds mean in Roulette, you’ll realize what bet options to go for and increase your chances of winning while playing.

Roulette odds, What does it do, and how can you calculate it? In this casino news, we’ll discuss everything about it and other factors, such as the house edge and payouts. 

Roulette Odds: Maximizing Your Winnings to Beat the House

Roulette odds help you determine the probability of winning a bet. And the chances for each bet differ from each Roulette variant. Your influence over the game is low compared to other casino games, such as 3 Card Poker, Blackjack, etc. For example, the likelihood of winning an even bet in American and European Roulette is 46.37% and 48.6%, respectively. The reason for the difference between both Roulette variants is that the American variant makes use of both single and double zeros. In contrast, the European variant uses only the single zero.

Another factor to take in place is the house edge: the percentage cut the casino has over every bet a player makes, as that is how casinos profit.

How to Calculate Roulette Odds and Payouts

Understanding how to calculate Roulette odds helps you know your winning chances. Therefore, giving you an edge over other players when placing a bet, whether if you play live or online at Slots Paradise. Here is an example

If you place a bet on three numbers, you divide 36 by the three numbers to get 12. Now deduct one from 12, and that gives 11. Therefore, the odds are 11:1.

Now that we have calculated the odds for a three-number bet, how can we calculate the payout? That also is very simple. The ratio in mathematics is the same as division, and since we have the odds in a ratio form of 8:1, we divide it and multiply the result by our bet amount.

You bet $10 and win; your payout will be $80.

Inside and Outside Bets

Roulette majorly comprises two types of bets, and the probabilities of winning each bet differ from the other. Let’s briefly go through the inside and outside bets available in Roulette.

Inside Bets 

The name inside bets was derived because these bets are found in the inner layout of the Roulette betting table. Generally, inside bets have a low chance of winning because of the big payout odds they carry. An example is the straight bet, where the player wages on only one out of 36 numbers and has a vast payout odd of 35 to 1. The house edge is also effective in these kinds of bets already. Below is the chart for inside bets:

  • Straight Bet 35 to 1
  • Split Bet 17 to 1
  • Street Bet 11 to 1
  • Corner Bet 8 to 1
  • Basket Bet 6 to 1
  • Double Street Bet 5 to 1

Outside Bets

Compared to the inside bets, outside bets are found in the outer section of the Roulette betting table, and they generally have a high chance of winning. However, the only comeback with outside bets is that the winnings are less than outside bets due to the increased odds. It is understandable because outside bets comprise half of the bets on the Roulette table. 

Below are the types of outside bets in Roulette and their payout odds.

  • Red or Black 1 to 1
  • Odd or Even 1 to 1
  • High or Low 1 to 1
  • Columns 2 to 1
  • Dozen 2 to 1
