The best online slots

The best online slots
A gaming machine is an automatically functioning gaming device that starts a game of chance after a bet, the outcome of which depends on the chance and actions of the player. That is, the best online slots are combinations of great luck and little skill. Most of the games are based on the parallel launch of several reels with the same rows of symbols. The player starts spinning the reels. After a short time, the reels stop. If three or more symbols, then displayed on different reels, match, a win is achieved. Most slot machines operate with three to six reels.

The variations of the game can be very different. But, the best online casino slots are initially based on a very simple and uniform system: there are a fixed number of reels, on which a fixed number of different symbols are distributed. Each time you spin the reels, a combination of symbols appears that determines whether you win or lose. There are an incredible number of slot machines and everyone knows it. 
Many players ask themselves the question: which are the best online slot sites? And anyone familiar with those machines knows that this is actually just a hypothetical question, because the quality of the machines is not easy to measure. Also, not everyone uses a computer today, preferring an iPhone, iPad, Android or tablet. This makes it more or less impossible to find the answer to this question, but of course it makes sense to sort it out anyway, because it increases the chance of finding the best online slot that suits you the most. 
Internet gaming has breathed new life into slot machines. Now players have a chance to win big with their mobile phones at home or on the go, and there are even more ways to win. Classic arcade online slots to play usually have only three reels and one payline. On the other hand, some of them may offer 243 or more opportunities to win real money on five reels, and the extra odds of winning with bonus features are not even counted.

Probably the most interesting thing about the best online slot games is that there are so many different types of them. In virtual casinos, you have the choice among new video slots with gripping stories and gorgeous animations, classic fruit machines or jackpot games with huge wins.

Criteria of choice

The range of the best online slot sites is wide. They often differ in terms of game catalog, bonuses, VIP programs and other features. You yourself know best what is important to you when choosing a casino. But some important criteria include:

Bonus offers

With good welcome offer, you can get extra credit and free spins. Often these additional spins are provided as a gift on your first deposit, but existing customers can also get free spins for onward deposits as well.


The best slot sites for real winning, of course, can offer you a big choice of different gameplays, as well as of different software providers and betting limits, so you don't get bored quickly.

Mobile interface

It has become natural to optimize Internet pages for smartphones and tablets. You often can previously check whether there is an application to download and whether it is compatible with all mobile devices.

Payment methods

In order to start playing right away, when choosing a casino, fast and safe deposit and withdrawal methods are important. The best online slot machines sites offer time-tested methods of payment by credit card or bank transfer. Meanwhile, so-called e-wallets, such as Neteller and Skrill, have also become popular. Identity verification must also be done prior to payment.

Unique features

The experience with the best online slot sites can be improved not only through the features of the gameplay. Some new casinos often offer their customers an app and a Touch ID login. Sometimes you can also make a deposit while playing.

Industry reputation

Good customer service and a great welcome bonus do not equal reputation. That is why it is important to collect the opinions of customers and experts. Partnerships with software developers also play an important role.

Security and support

Top slots websites have secure encryption to keep your data and payment transactions as safe as possible. The customer support team also needs to be quick to respond, work on finding solutions and, if possible, able to speak your language.

Software providers

Top casino software developers provide quality and variety of games. Names like NetEnt, Microgaming, BetSoft, Yggdrasil, Red Tiger, NextGen or Play'n GO offer huge game catalogs and many different types of real money games with a fair chance of winning.

Licenses and regulations

The best online slot sites must, of course, have a valid license from a reliable supervisory authority and comply with the prescribed rules.

Luck needs a system

If you decide to try your luck on the reels, or if you are simply fascinated by the mechanisms underlying the game, you will ask yourself if this is really just an accident of winning. First of all, remember, that there is no perfect system for achieving success in gambling. The game systems that the best online popular slot machines are built on are too complicated for that. Depending on the brand and variant, the mechanisms that determine the well-being and grief of the player can be very different.
However, it can be very interesting to look behind the scenes of modern slots and learn how do they generally work, how do their winning systems work and, of course, how can this basic knowledge be used to increase the chances of winning and having fun?

Random thing

Basically, when playing the best slots, the principle of randomness operates. We are talking about mathematical probabilities and when which symbol will appear on the reel. However, players should be aware that their chances of winning are not entirely arbitrary. If you assume that each reel starts individually at the start of each game and stops randomly again, you will make a mistake in most cases. However, this assumption would be necessary in order to actually be able to proceed from classical mathematical probabilities when determining the odds of winning.

In fact, the best online video slots are based on a system that accurately determines the frequency of winning combinations and the percentage of wins associated with them. This is done using a probability algorithm that can be very different. At the beginning of the game it is already clear which combination will come out at the end. 
We can also say that all slot machines work according to a certain principle: the greater the paid profit, the less the probability of getting the desired combination. Each machine is programmed in such a way that it only pays out a certain percentage of the amount deposited by the player. This percentage is called the payout ratio and ranges from 60 to 98 percent, depending on the gaming system and provider. This usually means:
  • 60 percent for the slot machines;
  • 90 percent for the slots in casinos and gambling houses;
  • 98 percent for online casino slots.
So, if you want to win large sums, you must invest large sums first. With a small bet, only small and medium profits are possible. Each slot machine to play online has a probability system that determines how many games the user has the opportunity to take advantage of. Here again the already mentioned basic rule comes into play: the greater the paid profit, the less probability of getting the desired combination. For the top online popular casino slots, this means very practical: if it out wins often, they are usually not big at all.

Payout and RTP

This is directly related to the deposit bonus and jackpot. If you play a 90% payout slot machine, it shouldn't be a bad thing if everything else is good and can compensate for it. The bottom line is that you can win more with a worse payout if the bonus offer is better. Basically, of course, you should prefer the slot that has the highest chances of winning.
The best paying online video slots have become incredibly complex. Unless you are a mathematician, you can never fully understand them. The RTP value only says how much is returned to the player on average. But, sometimes the payout exceeds 100%, namely when a large progressive jackpot is expected. Of course, it is unlikely to be hacked. So in the vast majority of cases, it looks like the RTP with no jackpot is 80%. A lot of people make the mistake of sticking to RTP, not paying attention to volatility at all. A high RTP can only be achieved with very high but unlikely payouts. In other words, in most cases and sessions, you won't get any of this. After that, you can play for weeks without making profit.
The best slots games have a payout that optimizes pleasure in the short to medium term, when you can make small to medium profits – ideally at least one per session. In this case, it leads to large "fluctuations". But isn't that what the casino players like? Just imagine getting 0.98 for every dollar per spin. Wouldn’t it be so boring? Therefore, good odds of winning do not necessarily guarantee high profits. The best slots with extremely high odds of winning include:
  • Aladdin's Lamp by Amaya with 98%;
  • Blood Suckers by NetEnt with 98%;
  • Devil’s Delight by NetEnt with 97.6%; 
  • Guns N' Roses by NetEnt with 96.98%.
In fact, it must be said that the quality of a slot machine does not depend on the software. An unknown vendor could produce a better slot machine than the big players like NetEnt, Microgaming, Playtech, Boss Media, etc. It doesn't really matter. But big manufacturers offer a lot more games to choose from. The most important thing is winning money and this mainly depends on a large deposit bonus and a jackpot. If the jackpot is progressive, you can win really big amounts with low stakes. This is exactly the strategy that many players pursue.

What should a beginner choose?

In order to make a right choice, it is necessary to define the criteria for evaluation. For example, you can compare based on the quality of the graphics, the number of prizes, the variety of games, or the probability of winning the jackpot.

The best slots can be classified objectively based on certain characteristics. It is difficult to compare slots and machines with extensive lists of bonus features as the features of these games are different.

The safest and most popular platforms

The best slots games are among the absolute bestsellers. In most cases, a simple registration is sufficient to enter the game. Disclosure of personal information is kept to a minimum for data protection reasons. However, age legitimation is absolutely essential as gambling is only allowed when you are above 18 and the slot machines are probably the most addicting form of gambling. But you can always try different variants with small stakes first.
It is not easy to name the best betting sites for slots. There are big wins in progressive slots. But if you prefer the lowest possible risk to lose, you would better choose a slot machine with a low volatility and a high payout rate. Smartphones and tablets are the most popular devices among online gamblers nowadays. Therefore, the best gambling sites tend to make their offerings available for mobile devices. The number of slot machines in the mobile version is practically the same as in the desktop version, so you will be able to play your favorite games on the go.

How to play for real money?

Once you find some of the best online slot sites, playing for real money is just a few steps away. First, register with the casino and make your first deposit. As a rule, for this you will get some bonuses and free spins. Then there are hundreds of different rated slots waiting for you, but in principle they always work the same and are easy to understand. When making a bet, you need to pay attention to several things:
  1. Installed coin value: Coin value usually indicates how much money you bet on each payline.
  2. Number of paylines: The more paylines you choose, the better your chances of winning are. They are usually multiplied by the coin value to show the total bet per spin. 
  3. Start: Press the Start button and spin the reels. If you want to play several rounds in a row, you can also set the number of automatic spins. The rate remains the same for all rounds.
  4. Bonus features: Depending on the game, there are more chances of winning with additional symbols and mini-games. Wild symbols provide, for example, the completion of winning combinations. When bonus rounds are triggered, there is the possibility of additional winnings without having to place another bet.
  5. Stay on budget: Keep track of your balance as you play. Playing with more paylines increases your chances of winning, but also carries a higher risk of losing. All reputable online gambling providers allow you to set limits.
  6. Practice before placing real money bets: Although there is the option to play for fun, you can only win by placing real money bets. Therefore, it is worth giving the games a try to familiarize yourself with the features first. 

Registration rewards and promotions

Free spins or welcome bonuses are one of the most popular promotions you can come across when looking for the best online slot sites. This offer is advertised by almost all of the gambling platforms and is essentially a good introduction to the provider. Bonus promotions earn players either an initial bonus money balance or a free spins balance for a specific slot machine. In both cases, the online casino bonus is a serious offer because you can start playing without using your own money. 
Top slot machines sites must, of course, meet numerous requirements in order to be attractive. What matters here is the existing license, the safety of information, the payment methods offered, a good selection of software suppliers, the number of games available, transparent customer support, ideally available around the clock, and a good F.A.Q. page. And last but not least, the website itself must be user-friendly, modern, and well-designed.
