How does a Roulette Calculator work?

Roulette game calculators have gained a very high online presence due to recent uses by gamblers both experienced and beginners to make it easier for them to calculate odds. The calculator aims to help the player make a more predictable and decisive playing style to suit their bankroll size. The calculator keeps track of the spins, colours played, even and odd numbers, and the frequency in which all options appear on the online roulette table in order to achieve the highest roulette odds probability at the online casino.

Pick a bet from the menu or click the icon on the table.

This helps to maximize the amount of time to play roulette table and to keep composure even during a winning or a losing streak. The calculator works by determining the most suitable base unit based on the bankroll size for the payout odds. The bankroll size is the total amount roulette players are willing to use in a single session. The base unit is a fixed amount that will be constantly wagered for every ball spin allowing us to determine the best online roulette odds.

To use the calculator, a player simply inputs the bankroll size in the required section and clicks to calculate the different odds. The calculator provides the safe unit (highest odds), the recommended unit (true odds), and a high-risk (lowest odds) unit which are all percentages of the bankroll size the player can wager. If the bankroll size is £500 then, a safe unit will be 1% of the amount thus £5, a recommended unit will be 2% which is £10 and a high-risk unit will be 4% thus £20. Many recommend not using more than 5% of the bankroll size.

These unit sizes determine how much of the bankroll size you will use and how long the bankroll will last based on the roulette probability calculator. Beginners and learners are more inclined to use safe betting units to find a strategy that works best for their playing style. The high-risk option is good for high rollers and more experienced players with strategies and more experienced playing styles looking for a higher roulette payout.

How are the Odds of the Roulette Wheel Calculated?

The roulette game is one of chance and luck. Similar to other casino games, the odds of losing are always higher than the odds of winning. For example, if you place a wager on number 20, the odds to get that correct is 1 out of 36 other numbers, so 1 to 36. Similarly for any other single number bets. This could be calculated as a percentage. The probability to win is calculated by dividing the number of ways to win by all outcomes.

This is then equal to the number of ways to win divided by the total of the number of ways to win and the number of ways to lose. For the same example on number 20, there is only one way to win and 36 ways to lose, so it becomes; 1/(1+36)=0.027x 100= 2.7% chance of winning. On a split bet, the chances might be a little higher as there are two numbers.

This shows the odds might increase with the inclusion of more numbers. For example, a roulette bet on the first dozen or the third column includes a significantly higher amount of numbers, 12 numbers. The odds against winnings however are the reverse of that, for the number bet of 20, it would be 36 to 1(36/1). Gambling, however, is a business and the casino should be profitable at the end of the day, thus beating the house might be harder than it seems.

Safe Betting Units

hi

This refers to the minimum amount a bettor is willing to wage on every single spin. The bet amount is mostly 1% of the bankroll size. A safe initial bet will usually give the player the longest time in the table even on a losing streak and is usually longer depending on the number of wins involved.

This wager requires discipline as is expected in all gambling games, especially in winning streaks. Three or four wins in a row might make you want to increase the base amount, thus being disciplined and following your strategy is important. It brings a more relaxed and conservative way of playing online roulette.

With a bankroll size of £1000, the safe unit is £10 which will provide this as the base amount on each spin. It is a more cautious approach to wagering and is great for beginners to learn and work on a strategy for their playing style.

A prominent advantage of this method is that it allows for the least amount to play and the longest duration of playtime. This is good for online casinos as they allow for very minimum wage requirements that might suit this playing style.

The disadvantage of safe bets however comes in land-based casinos that have a higher minimum wager requirement which might require a larger bankroll size. This could however be higher than most are willing to lose.

Recommended Betting Units

This defines the middle ground on betting and wager units. It refers to about 2% of the bankroll size. In our case, it corresponds to £20 of our £1000 bankroll size. Recommended units bring an optimized playing time and an adrenaline rush with each ball spin. It is optimized for just enough to control the urge to make higher risks and lower risks.

With it not being a very large amount of your preferred size, it allows for faster decision-making and efficiency with minimal losses in case of a losing streak and also substantially greater wins than a safer bet would generally bring. Generally, it tends to lead to a calmer playing method with less time and more value in each decision and win.

The advantage of using this particular unit is that the longer you can manage the adrenaline rush and keep calm in winning streaks while perfecting your strategy, the more you discover playing styles that are suitable for each bankroll size.

It however has considerably higher losses and less time than a safe unit wager with each consecutive ball spin or losing streak.

High-Risk Betting Units

There is a quote in gambling that “You should not wager more than you are willing to lose.’’ Temptation plays a larger role in luck games than most would credit. In a winning streak, the urge to increase the size of your hand increases with each ball spin, and regret later follows. High-risk units are the largest and safest wager amounts according to roulette calculators. In our bankroll size, £40 represents 4% of the £1000 bankroll amount.

This is high-risk high-reward territory. It is meant for bettors who would put it all on the line for greater returns on their wager. However, if it hurts or makes you angry every time the ball lands in the other pocket, then it is probably not for you and you should consider lower amounts.

This waging unit provides the shortest time on the table and commands the utmost decisiveness in selecting a wager. The rewards might be greater but so are the losses. In the case of a losing streak, five consecutive losses will have you £200 down on your bankroll size, the opposite is true for five consecutive wins you will be up £200. Care should be taken on placing any wagers in high-risk units.

They bring more returns in winning streaks and increase bankroll size significantly which is advantageous at the right moments, and with good management could make you earn more. However, your bankroll size could disappear as fast with 4% wagers on each ball spin in a losing streak. This means less time at the table and more regrets on wagers that have been placed. High risk is not for everyone and requires more careful strategies because of the greater amounts involved in wagering.

Determining the Best Betting Units

Different options will work well for different strategies and different bankroll sizes. Determining which works well for you is reliant on the experience you get on the table, the strategy, and the bankroll size you approach the game with. The idea of the best base unit is based on which percentage of your bankroll size you are comfortable with potentially losing on each spin.

If losing higher amounts makes you cringe then lowering this amount to the one you are comfortable with may be the way to go. Most will lose faith and increase their hand in a losing streak to regain their losses. It does not always work out and could lead to larger losses on the bankroll size. Getting the best base unit will depend on your strategy and the bankroll size you do not mind playing with and not going beyond the limit you set for yourself.

The best base unit could be the maximum amount you are willing to wager with the minimum risk to your bankroll size. Getting to this amount will depend on practice and shifting the values up and down until you get to where you are most comfortable.

Roulette calculators are not always right and the answer is not always definitive. Experiment with larger and small values in different scenarios to come up with the best strategy. Based on the odds of winning and losing, your base unit should offer security to your bankroll size for the maximum amount of time on the table. It is a game of luck, and there are no guarantees.

4 Ways to Increase Your Winning Odds

Learn Roulette Table Rules

Roulette is not different from any casino game with rules. The ball will always land on one number, but there is no way of predicting which specific number. Thus knowing some of the ways to take advantage of that mystery could increase the chances of winning.

The player can bet on a single number that offers the largest win while selecting the most amount of numbers, 18, which offers a lesser win value. Taking advantage of the different types could increase the chances of not losing your bankroll size.

Be aware of Odds and Bet Outcome Probability

Odds are expressed as a pair of numbers, which is the ratio of all the ways to win against all the ways to lose. The odds of winning a straight-up bet on our number 20 would be 1/36. Casinos however list the winning bets in reverse order thus 36/1.

Probability is different from odds. These are the chances of the outcome of an event happening. For a split bet, there are only two chances of actually winning on the table. Therefore 2/(2+35)=0.054 x 100 = 5.40%. In a double zero game that drops to a 5.26% probability of winning. Probability shows that the more numbers you can bet on, the higher the chance of actually getting one right.

Choose the Best Roulette Variant

There are 6 different variations of the roulette game. American Roulette is most common as it offers better odds and a low house edge. This version includes the double-zero pocket and the number arrangement between that and the zero is different. The European Roulette wheel does not include a double-zero pocket and has less house edge than American Roulette.

Double ball Roulette games are a variant of the European table, with an extra white ball, it is less common in casinos. Multi Wheel Roulette is another, not with two white balls but eight wheels, which might seem weird but is easier to understand and is mostly online.

Rapid Roulette is a favourite version as payouts are quicker and there is less interaction with other players or the dealer. Mini Roulette is last but not least. It involves a smaller wheel of 13 numbers. In regular roulette, you lose all if your bet does not cover zero, in mini roulette the bet only loses half.

Use a Roullete Strategy

In betting, not many strategies would work against the house. Understanding however which would cause the least risk to your wager amount could be all the difference. In online casinos, it is easier to lower house edge with variants like imprisonment and surrender. Predicting where the ball can land on the physical wheel is difficult, but somewhat manageable. Online roulette however is more random with the use of random number generators which are used extensively.

This means any number can turn up at any time leaving no room for patterns to form. Familiarity with odds and which combination has a higher chance of success could mean more for your strategy than waiting for patterns in the numbers. Having an idea of the odds and probability together with your wagering base unit and bankroll size could help you plan out your strategy and ways to improve your wager quality.

Roulette Betting Calculator Summary

attention-orange

A roulette calculator can be an important part of your preparation for a session. For beginners, it will help determine your unit sizes and show you options for the amount of risk. That is however the most it can do for any player. The rest is up to chance and strategy. Knowledge of the game and experience over time will reduce the influence of a calculator. You can use the knowledge gained on other forms of roulette i.e. Lightning Roulette.

The more you get a sense of which wagering unit is comfortable for each bankroll size you have, the less and less the calculator is required. It may help build discipline at the beginning but the experience is the best teacher. With no ability to increase your chances of winning whatsoever in a real game, it is probably not useful in the long run.

Roulette Probability Calculator FAQ

Casino.online FAQ

What are the odds of a zero and a double-zero?

The odds of getting a single zero or double zero are 37/1. In European roulette, it is 36/1. Zero is typically not even or odd and they are on their row with a different colour from other numbers, green.

What is the House edge of American and European Roulette?

The American roulette wheel typically has more numbers with the addition of a double zero. This increases the house edge to 5.26 which is -1x37/38 +35x1/38= -0.0526. European Roulette has a lower house edge compared to American roulette at 2.70% with a maximum of 37 values.

Does Roulette Calculator bring an advantage?

The calculator offers little to no advantage to more experienced players who can manage their units and bankroll sizes.  However, for beginners, it assists in measuring wagering units to give a sense of what might work and what might be too little.
