Is there a chance to win at an online casino
There is an element of chance in most gambling activities. The chances of winning at slots, roulette, baccarat, and craps depend on luck. Only in blackjack and poker experience and skills help to make more educated decisions that affect the outcome. In other games, the laws of chance are at work. In them it is impossible to predict the outcome, and the peculiarities of the rules guarantee the casino profit on a long distance.
However, in a single game, it is possible to multiply the bankroll. But you should visit the casino for fun, not for making money. And you have to pay for it. Big wins are a nice, but rare bonus. No strategy does not guarantee victory.
Basic math in online casinos
This concept takes the gambling site to the plus side. Understanding probabilities, mathematical expectation and variance allows for a more informed approach to betting.
Probability and mathematical expectation for casinos
There are 2 indicators in gambling: Return to Player and House Edge. What they mean:
- RTP.The percentage of bets that the machine returns to players.
- HE.Percentage of bets that the casino takes back to itself.
Both indicators work on a distance. Calculate them for one gaming session is impossible. In slots, it approaches the stated average values after hundreds of millions of spins. For example, if the RTP of the apparatus is 96%, then after a time from the put 1 million rubles to customers will return 960 thousand.
Payouts are of a random nature. One user with a bet of 100 rubles can get a win of x10 000. Another user with an investment of 100,000 RUB will go into a minus
Payouts are random. One user with a bet of 100 rubles can get a win of x10 000. Another user with an investment of 100,000 RUB will go into a minus.
Every day customers make thousands of bets. Some win, others lose their money. But after a while from such a machine, the casino still receives 4% of income from all bets.
This happens thanks to math. For an example, the classic roulette is suitable. It has 37 sectors (18 red and black each), as well as one zero. The chance of winning at the casino on a bet on a particular number is 37:1. However, the payout is only 35:1. In this difference lies the income of the establishment. Calculate the advantage of the casino in roulette is not difficult by formula.
Butuѕе Edge = probability of losing x bet – probability of winning x payout
Butuse Edge = probability of losing x bet – probability of winning x payout.
When calculating it is necessary to take information about odds from the table. With a direct bet of 1 ruble, the casino advantage will be: House Edge = 36/37 x 1 – 1/37 x 35 = 36/37 – 35/37 = 0.027.
To find out the casino’s income in percent, the value must be multiplied by 100. In European roulette without additional rules (La Partage and En Prison), the benefit on the distance is 2.7%. In the American version, this figure is even higher because of the second sector with zero. He increases the advantage to 5.26%. The point is the payout amounts – they are lower than the player’s risk.
In slots, calculating the probability will not work. They work with complex software algorithms. In some apparatuses there are thousands of possible paid combinations. They can fall out several times in a row or not hit dozens of spins.
The mathematical expectation shows the average result for a long game. It is always in favor of the casino.
What is variance
It is the deviation from the mathematical expectation. The term is more often used in mathematics to describe the variability of data. For gambling, volatility is more appropriate. It is an indicator of unpredictability and scatter of payouts. There are 3 types of volatility:
- High.These games have a high potential for big wins. But they do not happen often. Therefore, high volatility machines require a large bankroll.
- Low.Players receive payouts more often, but of small size. Their maximum multipliers are usually lower. These machines are less risky and suitable for users with a small bankroll.
- Medium.The same frequency of large and small payouts.
In some games, volatility also varies depending on the betting strategy. Roulette is again suitable for this example.
Betting on specific numbers has high volatility. Due to the low probability, payouts are infrequent, but the multiplier odds are large. Equal odds such as red/black and even/odd cover 18 numbers. The probability of winning at a casino in European roulette on these bets is over 48%. Therefore, payouts on them are more frequent, but the odds are only 1:1. This is an indicator of low volatility.
Events in the casino
In gambling, bets are made on various outcomes – the victory of the banker in baccarat, Pass Line in craps, straight in blackjack, etc. In other machines, users wait for the paid combination. These events are used to determine the outcome – win or lose.
Independent
The outcome of the current game does not affect the next one. It does not depend on the result of the previous game. For example, it is the roll of the dice in craps, the spin of the roulette wheel or the spin of the reels in slots. The result of one event does not affect the other outcome. The absence of a combination in the current spin does not increase the probability of its falling out in the next. The player can not influence this.
Dependent
In these, one outcome changes the probability of another. In the past, casinos used few decks in blackjack. Players learned to watch the cards that came out and determine when the right cards were dealt. This information allowed them to calculate when it was best to fold and when it was best to raise.
One of the most memorable situations in the history of gambling – the success of students at the Massachusetts Institute of Technology. Thanks to card counting, they took 13 years from the casino millions of dollars. This took place in the 80-90’s in the last century.
However, establishments are fighting these methods and are improving. In blackjack, increasing the number of decks in the shooz, trimming and shuffling cards make it impossible to count them.
Description of the law of large numbers
As the number of playing sessions increases, their average result will tend to the mathematical expectation. For example, the probability of heads or tails is 50/50. But this does not mean that after four coin flips, both sides will come up 2 times each. A player can flip tails 3 times and eagles only 1. But as the number of flips increases, the result will approach a 50/50 ratio. This is the law of large numbers.
However, in casinos there are no games with the same probability of results. Roulette has an unpaired number of sectors – 18 red and 18 black. Another one falls on the green zero. Because of it, the odds of winning at the casino are not 50%, but 48.65% (18/37 x 100). This is what benefits the establishment. The law of large numbers is valid in the distance. After thousands or millions of bets, the results will be close to the mathematical expectation and the return rate stated by the provider.
What is the law of two thirds
It is applicable to roulette. The law assumes that after 37 spins of the wheel will fall out only 2/3 of all numbers. That is:
- About 9 of them the user will see 2 times.
- About 3 numbers will be seen three times.
On the remaining 1/3 of the sectors the ball will not hit once. The goal is to guess which number will fall out again. According to calculations, the ball will stop for the second time in one of the sectors at about 8 rotations. But that’s the theory. The randomness of the results makes it impossible to predict them.
Principles of slots
In land-based and online casinos there are many categories of gambling. But the most popular are slots. Customers run them because of the easy rules, low limits on minimum bets, bright graphics and animation. But even more players are attracted by high multipliers. Coefficients can be x1000 and more. There are no such big payouts in card and table disciplines. Gameplay in slots is also simple:
- The player starts the machine and adjusts the bet amount.
- Selects the number of lines, if they are not fixed.
- Presses the button to spin the reels.
- Waits for the results after the completion of the spin.
The user receives the winnings when a payable combination appears. In the standard mechanics, a minimum of 3 identical symbols must go in a row from left to right. Combinations are counted only on active lines. You can see them, as well as multipliers for different symbols in the pay table. But there are other mechanics as well. For example, with cluster payouts, in which the winnings are awarded not by lines, but for the number of identical icons.
The results are determined by a random number generator. The program uses complex algorithms to ensure a random outcome. There are 2 types of RNG:
- Hardware.The device generates random numbers based on chaotic physical factors – noise level in the hall, etc. They cannot be predicted and cannot affect performance.
- Pseudo-random.Usually used in online casinos. Before release, slots are certified in independent laboratories. They check many characteristics, including the authenticity of the GSC. The program uses mathematical algorithms to determine the results.
When the spin button is pressed, the HCS produces an unpredictable sequence of millions of digits. Each of them is given a certain combination of symbols. Drum spins are shown on the screen to the player for interactivity. Gradual appearance of symbols adds excitement and the feeling that the outcome is not yet known.
There are several models of machines in land-based halls. They are divided by the type of case and seating:
- Upright.With a vertical monitor at eye level. Such machines have mechanical buttons.
- Slant-top.With electronic control and a monitor at an incline.
Appearance of the apparatus does not affect gameplay and chances to win in the casino. The principle of their work is the same. Regardless of the manufacturer, they must be certified. The settings of RTP and other characteristics are carried out at the development stage. The casino staff does not have access to the machines. They are sealed, and any interference in its operation is illegal. For repair, maintenance and other settings, employees from the provider’s side are necessarily involved.
What is a jackpot
It is accrued when a rare combination falls out or a certain event occurs. In slots, the jackpot is often played in the Hold and Win bonus game. To get it, you need to collect symbols on all reels. The types of jackpot include:
- Fixed.The amount is determined in advance.
- Progressive.grows with each bet. A certain percentage of them goes to the accumulation of the jackpot. The amount increases until one of the customers takes the main winnings. Then the jackpot is reset and grows again. These slots are usually set to a low RTP for faster accumulation.
- Mystery.This is a random jackpot. It is paid randomly to any player (regardless of combination, bet and other conditions).
Different jackpot rules are found in the machines. Information can be found in the payout table, game rules or in the help section.
How casino earns
The machines are developed by official manufacturers. Casino representatives place them in land-based halls. Online venues act as intermediaries between players and providers. They add slots to their sites. In this case, the administration of platforms do not have access to the settings of machines. They are downloaded from the servers of developers.
Operators earn on the difference between the invested amount and client winnings. RTP must be not lower than the minimum percentages approved by the legislation
Operators earn on the difference between the invested amount and the winnings of clients. RTP must not be lower than the minimum percentages approved by the legislation.
They vary from country to country, but on average they are 90%. If 1000 people put 10 thousand rubles in a slot with an RTP of 95%, then after hundreds of millions of spins the machine will return 9.5 million rubles. Thus at a distance casino is guaranteed a profit of 500 thousand rubles.
Each bet has a probability of winning. If in the case of a coin the chances of falling out of the eagle or tails – 50/50, then in the machines laid advantage of the institution. No gambling entertainment does not have the same probability of opposite outcomes.
Regulators monitor the operation of machines to ensure fair play. Slots must meet a number of requirements:
- Availability of certificates from independent auditing agencies.
- Determination of results by a genuine GSC.
- Compliance of the actual RTP percentage with the percentage declared by the provider.
- Correct calculation of payouts and other functions.
- Availability of seals – for land-based machines.
When using scripted games and interfering with the device, the regulator fines the casino. For systematic violations, his license is revoked.
Chances of winning in casinos in different games
The results in roulette, baccarat, slots, lotteries are random. In poker and blackjack, the chances of winning in the casino can be increased by knowing the rules, mathematical principles and some strategies. But on the distance still wins the casino. Depending on the stakes and the type of gambling entertainment the probability of outcomes is different.
Slot machines
In slots there is a large range of RTP. Despite the randomness of the results, the casino’s advantage is embedded in the characteristics. The payoff in them is never equal to 100%. Usually, slots return to players 90-98% of all bets. This does not indicate that they are tweaked. At the moment of pressing the button to spin the reels, the combination is determined by a random number generator. However, the calculation takes place according to a certain algorithm, which lays down the guaranteed income of the establishment.
Different types of roulette
There are 3 classic versions – American, French and European. They differ in the number of sectors and rules. The advantage of the operator when betting on a particular number is presented in the table.
| Roulette type | Number of sectors | Zero | Casino benefit, % |
|---|---|---|---|
| French | 37 | One | 1,35 |
| European | 2,7 | ||
| American | 38 | Two | 5,26 |
French roulette has additional rules that increase the RTP compared to European roulette. They apply to equal odds bets and save all or part of the player’s money when the ball hits the zero sector.
Craps
The rules of the game are not complicated. The shooter rolls two six-sided dice. When betting on the Pass Line, the player:
- Wins on a score of 7 or 11.
- Loses on a roll of 2, 3 or 12.
The other number becomes a Point and starts the second round. To win, the Point must fall before 7. There is also a reverse bet – Don’t Pass Line.
The payout on them is carried out in the ratio of 1:1. But the benefit of the institution at such bets is only 1.41% and 1.36% respectively. The maximum casino advantage in craps is 16.67%. It is valid for a bet Any 7.
Card games
In these, the chances of winning at an online casino depend on the number of decks, rules, bet type and strategy. The table shows the range for popular card disciplines.
| Game | RTP |
|---|---|
| Video Poker | 95-99,54% |
| Blackjack | 98-99,5% |
| Baccarat | 85,64-98,94% |
Other games
There are other table disciplines in the casino’s assortment, as well as lotteries, arcade mini-games. For example, in keno RTP is 20-40%. For online machines, the payoff is indicated in the description of the slot rules or on the official website of the provider.
Effectiveness of strategies to increase the winning percentage in the casino
Hundreds of materials with various recommendations are available on the Internet. Some even promise “win-win” techniques. But there are no such systems. The editorial staff has collected the most popular strategies and described their effectiveness for casino games. They work well when betting on events with a 50/50 probability. However, in gambling there are no such outcomes. As close as possible to these values roulette with bets on equal odds.
Martingale
Assumes doubling the bet when losing. The essence of the strategy is that a successful outcome compensates for all previous expenses and brings on top of the amount equal to the initial investment. For example, the user has chosen even numbers in roulette. The scheme of the Martingale game is in the table.
| Bet, rubles | Result | Bankroll |
|---|---|---|
| 5 | Odds | -5 |
| 10 | -15 | |
| 20 | -35 | |
| 40 | -75 | |
| 80 | Chet | 5 |
The odds of winning in a casino when betting on events with a 50/50 probability in European and French roulette are 18/37. In the American version it is 18/38 (because of the two zeros). The table shows the situation with a successful fifth spin. The player risked losing 155 rubles to gain 5 rubles. If the series of unsuccessful spins will continue further, the client will reach the maximum limits of the table. Low profitability, exponential growth of bets and restrictions on them make Martingale ineffective.
Positive progression
After winning the sum is doubled. The strategy differs from Martingale in that after losing the bet is halved. This reduces the risk of stopping at the maximum limits and quickly spend the bankroll. But the profitability of the strategy with positive progression is even lower. The scheme for betting on even numbers is in the table.
| Amount | Result | Balance |
|---|---|---|
| 5 | Chet | 10 |
| 10 | 20 | |
| 20 | Odd | 0 |
| 10 | -10 | |
| 5 | -15 | |
| 2,5 | Chet | -10 |
| 5 | 0 |
Biarritz system
Based on the law of two thirds. The player is guided by the fact that for 36 spins some numbers will fall out more than once. It is necessary to follow the results and further bet on the appeared values or avoid the repeated ones.
There is no mathematical basis for this system. It takes into account many probabilities. But all this works in theory. In practice, the chances of hitting the ball in a certain sector do not depend on whether it was in the cell in previous rotations or not.
Favorite number
Primitive methodology. The player chooses a specific number and constantly bets on it. The payout of 35:1 should cover all costs. However, for 36 spins, there is a high probability that the ball will not hit a certain sector. Some numbers will be repeated. The chances that no number will fall twice in 36 spins tend to zero.
Imperfection of the wheel
Used in roulette. It is based on the assumption that the wheel may have defects and irregularities. Because of this, some numbers fall out more often than others. Players observe the results in a land-based establishment or analyze the history of results in live roulette with live dealers.
However, casinos minimize such situations. They maintain the wheel, especially the rotor. Manufacturers specifically create interchangeable spare parts with the ability to install them quickly. Development technologies are constantly improving. The use of quality wood species and their careful processing prolong the life of the equipment and reduce the risks of deformation.
Series of failures
The strategy consists in changing the bet by one unit – increasing after a loss and decreasing after a win. Unlike Martingale, the investment grows in arithmetic progression. Therefore, the system is more resistant to a series of failures and maximum table limits.
How winnings are paid out
After a winning combination in the machine does not fall out hundreds of coins. It is not uncommon to get TITO coupons instead.
They have the amount of winnings and a barcode on them. They can be cashed out through cash dispensers, similar to ATMs.
There are maximum limits for exchanging TITO coupons. Withdrawal of large sums is available only at the cash desk
There are maximum limits for TITO coupon exchange. Withdrawal of large amounts is available only at the cash desk.
In online casinos, payments are immediately credited to the main account. Exception – winnings from bonuses, which before withdrawal must be “unscrewed”. Withdrawal of money is made through popular payment systems. Withdrawal is possible to bank cards, electronic or cryptocurrency wallets. There are also minimum and maximum limits on transactions. Requests for payment are created in myAlpari gambling site.
Tips to increase the probability of winning at the casino
Customers can not affect the results in gambling entertainment. In poker and blackjack – only indirectly. But players can properly manage the bankroll and maximize the benefits of bonuses.
Loyalty programs
Casinos with a good reputation care about the comfort of guests. To attract customers, organizers arrange drawings of large sums, cars. Many land-based establishments have a loyalty program. When registering for a client, a card is issued. It accumulates bonuses for active play for money. Then they can be exchanged for free spins in slots, tickets to tournaments and other promotional offers.
Some players are complimented by the casino. For customers can pay for drinks or food, hotel stays and so on. The administration determines such bonuses individually
Some casino players receive compliments. For customers can pay for drinks or food, hotel accommodation and other. The administration determines such bonuses individually.
In online casinosbonusovechestva more. Promotions on the Internet are more accessible. In addition to the loyalty program, there are no-deposits for registration, interest or freespins on first deposits, cashback and other promotional offers. However, they have a disadvantage – wagering conditions. In this case, the wager often exceeds x30, which makes it difficult to fulfill the requirements.
Budget accounting
On gambling, it is necessary to allocate an amount that is not sorry to lose. Setting limits will allow you to stop betting in time and not spend more than planned. Limits should be thought through not only in the case of losing money, but also winnings, spending time in land-based establishments or online venues.
Other tips
There is a chance to win at casinos only with a license. They use official machines, in which the results are determined by the GCH.
Before playing for money, you should study the rules and decide on a betting strategy. This will help you make more informed decisions
Before playing for money, you should study the rules and decide on a betting strategy. This will help you make more informed decisions.
You should control your emotions and not try to win back losses. This can lead to ill-considered bets and even more expenses.
If you have a small bankroll, you should choose machines with low volatility. Customers also consider the winning percentage at online casinos when choosing a machine. Although RTP works on a long distance, indirectly the indicator helps to estimate the chances of winning.
Frequently Asked Questions
It is worthwhile to open the help with the rules and payout table after launching the game. In the absence of information, you can go to the official site of the provider to the page with a preview of the slot.
Yes. In slots, the payout in the main and bonus games may differ. Also, providers sometimes create machines with multiple RTP for different jurisdictions.
Such machines are not certified. They do not work in the GSC. Characteristics are configured so that the player has no chance of winning. The casino administration has access to the code to underestimate the RTP.
Their activities are controlled by regulators. In case of violations, the gambling site is issued large fines and can deprive the license. A bad reputation will reduce attendance. Legal casinos are not interested in deception, because at a distance they are still in the plus.
Depends on the laws of the country. In some jurisdictions, playing in casinos is allowed from the age of 18, in others – from the age of 21.
