Slot Machines: Peculiarities, Types, Selection Criteria

Slot machines have made a long way from hardware complexes in real establishments to slots in online casinos (online casinos ranking). Now visually it is an interface of 3-5 drums (some developers, however, have already created six-drum slots, but these are few), starting to rotate after pressing the Spin button. Winnings are formed taking into account combinations and bonus levels composed after the stop. Thus, almost always in a slot there are special characters and combos, collecting which, you open the opportunity to earn extra (casinos bonuses). The bet rate is determined by the online casino.

Types of slot machines

There are 3 main types of slot machines on the internet: classic slots, video slots and progressive slots:

  • Classic slots are visual analogues of standard physical machines based on mechanics. Classic symbols are used (card suits, bar dishes, flora and fauna). They have a minimum number of paylines (collectable combinations) and drums (usually three).
  • Video slots are modern digitized machines with plot lines, original themes and interesting animation. Technically, they are similar to the classic online slots, but more elaborate, and therefore more interesting to play. Functionality here is limited only by fantasy and budget of the developer.
  • Progressive slots are those that support the function of progressive jackpot, when the winnings increase in mathematical progression based on the success of your actions, and can grow by 10, 50 or even 100 times, if you’re lucky enough. After all, the prize pool is formed from the spins of not one person, but all players in a specific time period.

How to choose a slot machine

The first thing to pay attention to when choosing a slot machine is its return rate. This is an indicator of the expected return of investment, obtained from the conducted testing. Ideally, testing should be carried out by an independent competent entity: this is what GLI (Gaming Laboratories International) is now considered in the gambling industry. And even if the casino does not provide results, you can see them on the resource of the entity itself. From this point follows the second important feature of the right machine: the authenticity of the software (software developers). It is important that it was an official game, not one copied from the developer. Provider should also be known and enjoy a good reputation. After all, it depends on him how profitable will be the game conditions.

Main slot machines developers

The market for game software developers is changing. If a few years ago the top dogs were considered to be Microgaming, Playtech, Betsoft, NetEnt, Playson, Novomatic and a number of other names, today most of them have become secondary, and the market was divided among «the old guards» and such companies as Mercur Gaming, 1 x 2 Gaming, Red Tiger, Thunderkick, AGT, Rabcat, Cayetano and others. At the same time, Ezugi still holds the lead in games with live dealers. Even the list of popular developers includes more than 70 titles. Little-known ones are many times more. To list, and even more so to characterize all of them within this material is not possible. The choice of products is so huge that each establishment can to choose something among the collections to suit its format and taste.

Game peculiarities in demo mode

The demo mode is no different from the regular game mode visually: the same interface, the same features and bonuses. However, do not forget that its purpose is to attract the client. This means that the profitability (recover) here will be definitely higher than in the game for real money. Therefore, you shouldn’t assess the winnings of the machine basing only on earnings in the demo version.

What casinos should you play slots in

In order not to go broke, we advise to adhere to the following criteria for selecting online casinos:

  • The availability of an officially recognized license. Ideally it should be a reference to the registry of the regulator, where the establishment or the document itself is listed (again, posted on the page of the regulator). Licenses can be quite different, though: Malta (MGA), UK (United Kingdom Gambling Commission) and Gibraltar (Gibraltar Betting and Gaming Association) have the highest authority as they strictly control the financial flows of the licensees, follow the established requirements of user verification and respond promptly to any complaints. Curacao Internet Gambling Association, on the other hand, due to the fact that it has been observed in the issuance of master licenses to unreliable providers that, in turn, sell the authorization to conduct gambling activities to scammers, is questionable.
  • The open results of testing the software that demonstrate not so much the real return of the machines (this is pretty relative) as the fact that the products are licensed, and not copied from the original developers. The availability of original content does not always mean that the entire collection is legal: often only a third of it is bought from developers, and the remaining mass is taken for a modest fee from plagiarists. Compare the number of these items in the lists of the library and tests, if you want to play the original slots.
  • Selecting manufacturers: Microgaming alone in the list of providers should alert you. After all, it is the most «popular» game software developer among all kinds of cheaters. We are not saying that the service provider himself is cheating customers, but there is a huge number of copies of its games online, which are used by dishonest resources. Meanwhile, the presence of at least 10 names says, firstly, about the status of the Internet club and, secondly, about the execution of a number of security requirements.
  • Mentions in the official media, not only on the partner (paid) resources, show the legality and allow you to learn about possible controversies with non-payment of winnings.
  • The size of the minimum deposit: the higher it is, the more risks there are. If there is a positive assessment result on the first four points, it certainly does not matter so much, but if there are doubts about the integrity of the provider of gaming services, it is worth to be insured and start with a small amount.

Casino license number

For example, here are a few names that we consider reliable. First, 888Casino. The casino opened in 1997 and was licensed by Gibraltar and the UK. It offers a collection of 400+ products from dozens of providers and its own software. The site presents a public test RTP GLI (average return rate – 96.39%).

Secondly, Betsafe. This one exists since 2006, the minimum first payment here is only 10 euros. At the same time, you have access to more than 1,000 entertainments of almost 20 developers plus the company’s own developments. It operates under three licenses: MGA, AGCC, UKGC, and works with 600 thousand gamblers from 100 countries.

Types of casino slots

Thirdly, Energy Casino. This is a comparatively young operator (since 2012), which is, however, popular with European gamblers, primarily due to a good policy of relations with users. It provides a choice of over 600 games from 10 developers. Regulated by MGA and UK. Of course, the list of trusted resources is not limited to the above, but will give a clearer idea of the selection criteria.

How to cheat a slot machine

There is no ideal strategy to ensure that you bleed the machine dry every time you play it. However, there are some recommendations that increase the chances of success:

  • Play on small limits. In this case you will not waste the deposit and will be able to control your earnings.
  • Change the slot after 5-7 losses or winnings in a row. There is a certain regularity, periods of victories and failures, once in which it is important to stop in time: in the first case, so as not to lose later (the winnings are followed by a sharp downfall), in the second: in order not to nullify the balance immediately.
  • Do not use strategies such as Martingale’s and Fibonacci’s: all providers have long ago put in their software systems of their recognition and successful counteraction. Also, if the casino discovers a player is cheating like this, he simply gets blocked right away.
  • Do not activate bonuses. As soon as you are «given» free spins or cashback, you are a hostage of the system that requires to play the promotional funds back, increasing the balance 30-60 times. While you are doing this, the loss is deducted from your personal, not the bonus balance, and the winnings are saved only for the duration of the promotion. If you don’t have time to play, everything will burn down, except your money (if by that moment there still is such thing).

A conclusion

We’d rather call slot machines an entertainment than a reliable way to earn money. Modern games compete in animation and sometimes resemble full-length cartoons, and the mechanics themselves are so spectacular that you feel involved in the process, forgetting about everything. The developers are numerous, and it allows you to choose the plot, styling and functionality to your taste. There are no winning strategies and algorithms, as opposed to the same poker or blackjack, so we advise you not to chase a phantom dream, but to set a comfortable game limit (how much you are willing to spend, say, a day, week or month) and have fun. In order to make money you should choose another variety of online gambling. The main thing is to find the right casino.
