Slot machines online

slot machines online

Online slot machines are one of the main categories of entertainment presented on online casino sites.

They are software for playing in demo mode or for real money (at the player's choice).

They appeared in the late 1990s as an alternative to real slot machines installed in land-based casinos.

Slot machines for money is a category of gambling that attracts the attention of most of the audience of online casinos. More precisely, the majority of customers come to virtual gambling establishments precisely to play slots. These are simple programs with an attractive design, an interesting plot, and simple rules.

How to choose a slot machine online?

The choice of a slot machine is based on several principles:

slot machine

  1. Licensed status - before starting the game, check the online casino's license and check if it has a formal agreement with the program developer.
  2. Choose the best type of slot based on your personal preference. To achieve an acceptable result of the game, it is necessary to study and understand the rules regarding the formation of bets, the number of lines and the possibilities for multiplying the winnings.
  3. Appearance - if the first two points are observed, further choice can be based only on the visual component. In a licensed online casino, you can choose any slot to your liking, since there is a fixed return percentage for each of them. Its value is regularly tested by supervisory authorities.

This is not a mistake or a joke, all arguments about the advantages of certain slot machines are based only on attracting attention. Don't trust reviews that say otherwise. If the casino has a licensed status, regularly passes the necessary checks and cooperates with the provider on a legal basis, then any slot guarantees you a game according to the rules.

Varieties of slot machines online?

Slots are divided into the following categories depending on the gaming capabilities and set of functions:

Varieties of slot machines

  1. Linear - the winning is determined by the number of matches in each line, non-linear matches are not counted.
  2. Nonlinear - the amount of prize money for drawing a bet is determined by a combination of certain symbols on the screen, regardless of their location along the lines.
  3. With the multiplication of the winnings - the prize money obtained from the results of the rotation can be additionally multiplied by interrupting the cards or choosing one of several continuation options. In theory, the winnings can be multiplied indefinitely; in practice, the probability of a positive outcome decreases with each round.
  4. Without multiplying the winnings - most modern slots do not provide an opportunity to multiply at the player's choice. The increase in the amount is possible due to the presence of certain bonus symbols on the screen.
  5. Bonus - in addition to the usual symbols, there are special (bonus) symbols on the reel. Their appearance on the screen in a certain number (usually three or more) automatically starts a bonus round, in which the player gets the opportunity to win money without investing.
  6. Jackpots are a special category of slot machines in which there is a probability of getting a big prize under certain conditions. The jackpot bank is formed at the expense of a fixed percentage charged on each bet. The money set aside by the slot is received by the only winner who managed to fulfill the established requirements (most often - to completely pass the bonus round).

In terms of visual design, slot machines are divided into two main categories - classic (two-dimensional) and modern (three-dimensional). At the same time, 3D graphics are gradually replacing the "flat" slots familiar to experienced players like Crazy Monkey or Fruit Cocktail.

How do slot machines online work?

The principle of operation of slot machines is based on a random number generator, which gives out combinations in accordance with the laid down algorithm. The RTP is calculated depending on the settings set by the algorithm. It is a percentage of the amount of money that, on average, is returned to the player as winnings. Approximately according to it, you can estimate the chances of making a profit - the higher the RTP, the more likely a positive outcome of the game.

slot machines work

Online slot machines are regularly checked for RTP compliance with established standards. Moreover, reliable licensed casinos cannot in any way affect the percentage of return of the slot to the player. The licensed software they use provides for the placement of a generator, which is responsible for calculating the result, on the servers of providers, that is, game developers. By connecting to them, the casino gets the right to use the game shell, but does not get access to algorithm for calculating rates. RTP is calculated according to statistical indicators for a certain period of time and for decent establishments is 96-98%. This level of return ensures that the average player will win back $ 96-98 for every $ 100 invested.

Slot machines or video slots are programs installed on the servers of developers (providers). By entering into a formal agreement with the provider, the online casino gains access to their functionality, but does not have the ability to influence the results of the draws.

Visually, on the online casino website, slots are presented in the form of a screen that displays the rotation of a virtual reel. In most cases, the drum consists of five independently rotating wheels with symbols on them. As in the original slot machines, the result of the bet is determined depending on the combination of symbols dropped on the screen. Three or more matches in a row in one line lead to a win, the amount of which depends on the amount of the bet.

The size of the bet is determined by the player, but it cannot be less than a fixed minimum value. In addition, before starting or during the game, the user can set the number of lines involved in the game. The amount of each bet is divided by the number of played lines. The winning is calculated for each line separately. In case of simultaneous coincidence in several lines, the won money is summed up.

The slot program is controlled by a pseudo-random number generator (PRNG), which determines the result of each rotation (spin) displayed on the screen. PRNG is a hardware and software complex responsible for the formation of a numerical combination, which is converted on the screen into a sequence of characters. The fairness of the results of the game with the use of PRNG is determined by the fact that the appearance of each symbol on the screen has an equal probability.

The trick of the slots is that in order to win, you need to get a certain combination of symbols, that is, three or more in a row. In this case, in most cases, only those matches that start from the left edge of the line are taken into account.

The problem for gamblers is that many online casinos use pirated software, counterfeit licenses or use secondary versions of them. In such cases, only specialists can determine the honesty of the slot machines posted on the site. In a short period of time, a random number generator can produce many directly opposite results, it can drive all bets into a minus, or it can produce fabulous profits. Calculate RTP correctly slot machines online for money is possible only at a distance of several tens of thousands of spins.

The way out is simple - you should play only in those online casinos that guarantee high quality of service and originality of the software used. In addition, the best establishments can document these guarantees. Therefore, you should carefully check the gaming club for the legality of its actions. To do this, you need to familiarize yourself with the information about the license and its validity period, check the security testing certificates for monetary transactions, familiarize yourself with the data on encryption of personal user information. You will find the best online slot machines for money only in those clubs that openly provide such information on the official websites.

If you do not want to understand the documentation and check the originality of its origin, you can trust the opinion of experts. The main thing in this case is to choose the correct source of information. We recommend all visitors to our site to familiarize themselves with the unique rating, which was developed by the resource's own expert team. In the proposed list you will find all the brand names that are important for comfortable and safe gambling, as well as descriptions of the welcome bonuses relying on new customers.

Can you really win money by playing online slots?

The answer to this question lies on the surface. Since the algorithm for determining the drawn combination of symbols uses a random number generator, the result of each bet is actually unpredictable. But to guarantee the maintenance of interest among players, as well as to protect their interests, the developers introduced an additional indicator - RTP.

RTP is a parameter that determines the percentage of money, on average, returned to players on a given online slot machine. Taking into account the fact that casino owners expect to make a profit, this coefficient cannot be equal to 100%. But it will not work to lower it to the minimum level either - organizations that issue licenses for online casinos are watching this. In most licensed gambling establishments, this percentage is set in the range from 95% to 98%. This ensures fair distribution of funds among the participants in the game. Thus, 95-98% of the funds invested in the machine take part in the drawing. But in what proportions they are distributed between the players - his Majesty decides the case.

Slots bonuses

It is worth writing about bonuses and prize rewards separately, since they attract players to certain slot machines. If there are no bonus draws in the slot, and only winnings are taken into account when symbols match along the lines, such a device quickly becomes boring due to the monotony of the scenarios being played.

Slot machine bonuses are divided into three categories, which can be present either separately or all together, as part of one game:

Special symbols

Rescue sectors on the virtual reel, which give a chance of increased winning or even allow you to count on a big jackpot. Depending on the generation of slots and the manufacturer, symbols with the words Bonus, Scatter, Wild can be used as bonuses.

The Bonus symbol implies the launch of a special round with a free prize draw. Most often, the bonus game is triggered when three or more such sectors appear on the playing field, regardless of their location and distribution along the lines. The image on the symbol can be anything, but in most cases it is directly related to the theme of the slot. A memorable example of a Bonus symbol is the monkeys from Crazy Monkey or safes from Resident.

Scatter помогает образовывать образовывать выигрышные комбинации символов безотносительно их расположения на экране. В буквальном смысле «вразброс», что и означает перевод этого слова с английского. Кроме того, два и более выпавших скаттера приносят игроку фриспины, которые он может разыграть с дополнительными преференциями в виде статичных бонусных кнопок или увеличенного количества игровых линий. Призовая игра запускается при трёх одновременно выпавших на одном экране скаттерах.

Wild, that is, "wild", allows you to pull out the lost combinations or complement the winning ones with one more match in a row. Three identical and wild after them are equal to four identical. At the same time, the features of using wild symbols can be radically different for different slots. In some, they fall out quite often and contribute to an increase in interest in the game, in others they rarely fall into the same line with coincidences. In addition, some slot machines provide a large win for a match of three or more wild symbols in a row, and in some such matches are not counted at all.

Progressive jackpots

A separate category of slot machines is programmed in such a way as to periodically give out very large winnings, which, by analogy with lottery draws, are called jackpots. Most of them belong to the category of progressive, which differ in the way the prize pool is formed.

Progressive jackpot is a type of reward that is played in slot machines. The amount of the prize money is formed by deducting a certain percentage (in most cases - from 1% to 5%) from the amount of each bet lost on this slot. The accumulations formed in this way are displayed on the slot screen and updated in real time. For some slots, the accumulation of the amount of prize money occurs in a different way - due to the fact that, in parallel with the main bet, the player places a side bet (with a fixed amount), which gives a chance to win the entire jackpot accumulated so far.

Let's consider the order of drawing progressive jackpots using the example of software from one of the world's leading providers, NetEnt. In the Mega Fortune slot, players have the opportunity to win one of three jackpot options with different probability and different amount of reward:

  • Rapid - 1% of the amount of all bets involved in the drawing;
  • Major - 1.1% of the same bank;
  • Mega - 5.39% of the same;

At the top of the slot, you can always see the amount of the prize that is awarded to each of the winners in three categories. You can win the jackpot only while participating in a special bonus game, which is included in the slot program. Therefore, each bonus drop in slot machines of this type is doubly appreciated, as it can bring a fabulous enrichment. To win, you need to collect a combination from all levels during the spin of the bonus reel, which will lead to its center.

The developers of slots have tried to saturate them with interesting and colorful bonus drawings. But remember that only registration in licensed online casinos guarantees you the game on the original software that is connected to the servers of the providers. Using the services of scammers, you deprive yourself of the chances of winning.

How to choose a top casino from several hundred names on the Internet? There are three options available to each user:

  1. On your own - this will require you to study the capabilities of each service, reviews of real players, select the ones you like most, register, top up your balance and play for several months. In this case, it is necessary to test all functions - from making a deposit to withdrawing funds. For each of the pre-selected online casinos. This will require a significant investment of time and financial investments, since all possible risks will have to be checked on our own experience.
  2. According to recommendations - you can rely on someone else's opinion, but only if it is expressed by a competent person. You can try this or that site on the advice of a friend or trust the opinion of a blogger-reviewer. But in the first case, you at least know the person personally and he has no reason to lie to you. The situation with bloggers and reviewers is much worse - their posts and videos most often pursue purely advertising goals, therefore, they are far from reality.
  3. By rating - the third method is the simplest and most reliable. The ratings, compiled on the basis of an expert assessment of online casinos, are the most realistic sources of information. This is due to the fact that they take into account all the factors important for the players, and the establishments are ranked based on the aggregate scores by dozens of parameters.

Especially for visitors to our site, we have compiled a unique rating - top 10 casinos that deserve increased attention from gamblers of any level. Beginners, seasoned, experienced and professionals - in these gaming clubs for everyone there are generous bonuses, extensive collections of games, a high level of RTP and loyalty from the administration. When compiling the rating, we tried to take into account the maximum possible number of significant factors, paying special attention to safety and financial guarantees.

The top casino from the experts of our site was compiled on the basis of a detailed analysis according to the following criteria:

  1. Duration of work - it is difficult to assess the prospects of a brand if it has not been on the market for at least one year. But a lot can be said about a company that has been present in the gambling business for 5-10 years or more. Therefore, only experienced and time-tested gaming clubs entered the top.
  2. Licensed status - any guarantees from an unlicensed casino can be equated with words. They have no documentary evidence, so trusting them with your own money is extremely dangerous. Lack of a license is a reason to end cooperation with any, even the most attractive-looking gambling establishment. Our list includes only those who have a legally issued and currently valid international license. This is the basis for conclusions about the reliability and honesty of the company.
  3. Bonus program - each casino uses bonuses to attract audience attention. But in most cases, high-profile promises and fabulous sums remain unattainable due to unaffordable wagering requirements. Example - for a $ 100 deposit, you are given 100 dollars in bonuses. But in order to turn the bonus funds into real money, you must wager them by spinning 50-60 times the size on a certain slot machine with a limit on the maximum amount of the bet and the maximum winnings on it. it unrealistic conditions that become known to most clients only after registration and balance replenishment. You will not find such people in our top, we made sure that the rating includes clubs with a profitable bonus program.
  4. Financial transactions - among the best are online casinos with the maximum number of game account currencies, cooperating with all known payment systems. If it is convenient for players to pay with bitcoins or MIR cards, then they must have such an opportunity. Otherwise, the institution does not claim to be in the top.
  5. unrealistic conditions that become known to most clients only after registration and balance replenishment. You will not find such people in our top, we made sure that the rating includes clubs with a profitable bonus program.
  6. Game Collections - To get into the top 10 casinos, companies need to meet the requirements of today's players in terms of completeness of content. The assortment should include at least 1000 slots (including popular classics and the latest novelties), card games, lotteries, video rooms for playing with live dealers, lotteries, casual games, keno and other types of entertaining content. Ideally, up to sports betting.
  7. Website design and usability - people come to casinos for entertainment, therefore, the design of resource pages and the ease of transition between them play an important role in the overall brand assessment. Themed, clear and easy-to-navigate sites receive top marks.
  8. Almost every active Internet user has mobile applications - smartphones and tablets. Therefore, casino owners are obliged to take care of the convenience of access for their customers by ordering the development of branded applications for Android and iOS and mobile versions for browsers. Their absence speaks of a devil-may-care attitude towards the audience.
  9. Loyalty is an important aspect for those seeking to win. I registered, replenished the balance, won a large amount, put money on withdrawal - I got an account ban under a far-fetched pretext. This sequence is often encountered by customers of online casinos with a dubious reputation.
  10. Support service - the quality and speed of answering customer questions must be at its best. This requirement is one of the minimum in relation to any company, but it is not always observed in the gambling business. The administration is obliged to take care of the maximum number of methods of communication with operators, polite staff and round-the-clock work.

Based on the results of the analytical work done by the experts of our site, a rating of the best casinos with online slot machines was compiled. When forming the top 10, we did not pursue advertising goals, the list is presented solely to acquaint site visitors with the best representatives of the gambling industry. Each position in the rating is a reputable gambling establishment that you can safely entrust your money to without fear of theft, fraud or software cheating.
