# A Guide to Roulette Odds

The mathematical foundation of the game of roulette primarily involves the various probabilities of a particular bet turning out to be a winning one. By choosing the correct option, a player can significantly increase their chances of winning. However, with such a variety of betting options, one should calculate the likelihood of success and realistically assess the odds of winning. This is why experienced players know by heart the odds for each type of bet, which helps them accurately calculate their game strategy and navigate through bets. Therefore, before sitting down at the table, it's important to understand the intricacies of the game in order to know how great the chances are of winning in a particular variant of classic roulette. So, let’s deeply explain what are the odds on roulette.

## Methods of calculating Odds of success

The system of calculations is not as complex as it may seem at first glance, and with the desire, all necessary calculations can be performed mentally without using a calculator. To determine the best odds in roulette of winning in the game, one should divide the numbers covered by the bet by the total number of pockets on the wheel, and then multiply the result by 100. The obtained value will represent the percentage chance that the placed bets will turn out to be winners. For example, in the case of the European classic roulette, which has 37 numbers ranging from 0 to 36, the calculation is approximately as follows:

• For a straight bet, where a player places a bet on a single number, the initial value will be 1/37.
• Dividing these numbers results in 0.027.
• To get the percentage chance, this value should be multiplied by 100, i.e., 0.027 × 100 = 2.7%.

The calculations are somewhat different for a red/black bet, as this type of bet covers only 18 numbers. In this case, the equation looks like this: 18/37 × 100 = 48.64%.

It's important to note that this rule applies to the French and European versions of roulette, which have a single zero. In the American version, there is an additional double zero (00), resulting in 38 pockets on the roulette wheel. Therefore, the calculation formulas will be slightly different there.

Odds = Number of occupied field Number of overall fields x 100%

Number of overall fields = 36 for single zero roulette

Number of overall fields = 37 for single double zero
