This manual will be handy for both rookies and experienced gamblers. It contains a large array of useful information on how to identify top-rated slots sites and start playing on them. We will also tell you about the essence and characteristics of online slots, and how to pick them. Enjoy it! 

What are Online Slots 

Online slots occupy a large part of the portfolio of any gambling portal. This should not be surprising, because, according to statistical studies, such titles bring the casino about 70% of revenue. They have many advantages, the most important of which is the simplicity of the rules. Therefore, even newbies can quickly figure out all the nuances and start spinning the reels. 

There are two main categories of online slots: classic and modern video slots. They differ in graphics, the absence/presence of bonus features, the number of reels and pay lines, etc. Usually bonus features are accessible in modern slots, whereas classic ones are more suitable for old-school players and rookies. 

The heart of online slot machines is a Random Number Generator (RNG). This special algorithm determines the outcome of each round. It is impossible to hack it, and the correctness of the RNG is checked by independent testing agencies. At the moment when you press the button that launches the spinning of the reels, the result has already been determined, and you have to wait for the appearance of the final symbols forming the combination. 

Variety of Online Slot Machines 

In addition to the main variations of online slots, there are also other filters for categorization. There are quite a lot of them, and those that we will talk about below deserve special attention. One of them (high roller slots) is focused on certain punters, while the other two will suit gamblers with any bankroll size. 

Instant Play Slots 

In fact, this category includes most of the online slots presented in compilations of gambling operators from different parts of the globe. Instant Play means that the player does not need to pump games to his or her PC, laptop, tablet or smartphone to enjoy them. Each title is launched in the lobby utilizing a browser, which not only saves space in the gadget’s storage, but also excludes downloading from the number of steps separating punter from the start of the game. 

Here are some samples of instant play slots: 

  • Arabian Tales (Rival Gaming);
  • Ghost Rider (Playtech);
  • Starburst (NetEnt). 

High Roller Slots 

These titles, as can be understood by the name of the category, are aimed at punters with a large bankroll. If you have a limited budget, then enjoy them only in training mode. Otherwise, you will quickly spend all your money. 

The essence of high roller slots is that the min bet limit has been increased in comparison with the usual amusements of this genre. Participants of such games are offered targeted bonuses and VIP service. In addition, the RTP may be higher than in low-limit slots. 

Here are our recommendations: 

  • Buffalo Gold (Aristocrat);
  • Narcos (NetEnt);
  • Frankie Dettori’s Magic Seven (Playtech). 

Progressive Jackpots 

Most gamblers register at an online casino to try to win the jackpot. Slots can be fixed (the max amount available for winning is determined in advance) and progressive jackpots. In the second case, participants can count on the fact that they will be able to get a fantastic sum, and provide themselves and their family with money for the rest of their lives. 

Playing slots with progressive jackpots does not differ from the gameplay of ordinary titles. You place bets, spin the reels and believe in your luck. With each bet that all participants make, a small percentage is deducted to the prize pool. This allows the jackpot to grow until it is won. For example, in 2018, 18,915,872,81 EUR were won in the Mega Moolah slot! 

If you believe in your luck, try these progressive jackpot games: 

  • Mega Moolah (Microgaming);
  • Mega Fortune (NetEnt);
  • Major Millions (Microgaming). 

How to Pick Top Slots Sites 

If you are interested in playing secure and fair online slots, then you need to find a suitable site for these purposes. There are several important rules for picking a platform that we advise you to apply. This will help you avoid the possibility of becoming a victim of scammers. Pay attention to these aspects: 

  • Licensing. Online casinos must have an active international license from the best regulators, say, Malta Gaming Authority and Curacao Gaming Commission;
  • Reputation. Study the information about the brand in the public field. In particular, punter reviews and publications of journalists will help you with this;
  • Safety. The site must be defended by antiviruses, firewalls and SSL data encryption technologies;
  • Incentives. See what bonuses the gambling operator proposes, and are there any promotions among them for fans of online slot machines;
  • Amusements. Open the lobby and peruse the range of online slots, as well as check the availability of training mode;
  • Remittances. Proceed to the banking area of the site, or ask the support agents for information about which payment gateways can be utilized for incoming and outgoing transactions. Find out about the limits, the speed of funds transfer, as well as the absence or availability of fee;
  • Mobile-friendliness. If you like to play on your smartphone, then find out if a mobile modification of the online casino site is available or maybe it have a native apps;
  • Support. One of the most important aspects is the availability of the firm’s support agents. You should know through which channels you can contact them, and at what time they provide assistance (preferably they work 24/7). 

Now you know what to look for when picking the best slots sites. If you need samples, then study whether these operators are suitable for you: Las Atlantis, Lucky Tiger, Rich Palms Casino, and Shazam. 

Slots Bonuses 

Our readers will be pleased to know that gambling portals have special incentives aimed at punters who like to enjoy online slots. Below we will tell you more about such casino promotions. 

Free Spins 

Free spins is the main incentive aimed at fans of online slot machines. It is a set of a certain number of free attempts to spin the reels. There are several ways to get free spins: 

  • Often they go in addition to extra funds in the Welcome bonus;
  • They are available in the form of reload bonuses;
  • They are included in the list of benefits of VIP/Loyalty programs;
  • Free spins can be purchased in slots with the Bonus Buy feature;
  • A set of free spins can be given as a no deposit bonus. 

Also, online casinos can give the player benefits as an apology for a mistake on their part. Say, for a delay in the payment of winnings or technical failures during gameplay. 

VIP Slots Programs 

VIP or Slots Loyalty Rewards are special programs where regular customers of gambling operators can become participants. They are not specifically targeted at slot lovers, but such players will be able to receive various benefits by taking part in them. 

VIP/Loyalty programs usually consist of several levels. Each user starts with a zero status. To level up and unlock the benefits associated with it, you need to play games for real money. Thanks to this, you gain points, which are required to obtain a new status. 

VIP Slots Programs participants can count on these benefits: 

  • Free Spins;
  • Extra funds;
  • Cashback;
  • VIP service;
  • Targeted bonuses;
  • Increased withdrawal speed;
  • Birthday gifts;
  • Real prizes (say, smartphones of the latest models). 

Slot Tournaments 

This is one of the most enjoyable and exciting activities on gambling portals. Operators often hold joint events with their partner slot providers. Only registered and authorized users can participate in them. The pool of qualifying games and the min stake size are determined for the competition. Participants play for cash, and for each bet that meets the conditions, they receive points. The more points, the higher their position in the leaderboard. At the end of the event, a certain number of players, say, the top 40 positions in the table, receive prizes. 

In the event conditions, the prize pool is usually prescribed, as well as the distribution of money and free spins between gamers. One of the cool examples of slot tournaments is Drops & Wins from the famous provider Pragmatic Play. The concept was launched in 2020, and has gained huge popularity. It is important to note that in addition to prizes for the leaderboard, its participants can count on daily rewards. 

How to Pick the Best Online Casino Slots 

Picking a trustworthy website for playing online slots is not enough. The second crucial step is choosing a title. Punters’ preferences may vary by theme, modernity/old-schoolness of the game or other aspects, but in any case, when selecting amusements, attention should be paid to the points that we will discuss below. 


Return to Player (RTP) is an indicator that determines the percentage of money returned to players at a distance. The higher it is, the more profitable it is for punters. We do not recommend playing slots whose RTP is below 90%. It is best to choose titles with indicators of 95-96% or higher. It is worth noting that in progressive jackpots, the Return to Player indicator may be lower than the standards we recommend. But, the size of the potential winnings does not stop gamers from playing such slots. 


Volatility determines the frequency and size of winnings in online slots. So, with low volatility, winning combinations appear more often, but the amounts are small. With an average indicator, the amounts are higher, but the winnings happen less often. Finally, with high volatility, winnings can be expected for a very long time, but their amount can amaze even seasoned punters. 

There are also medium-low and medium-high volatility, which are transitional stages between the types that we described above. 

Pay Table 

The pay table is presented in the options of online slot machines. Punters can peruse it by running the game in any mode — whether paid or free. The table contains handy data that will help you to figure out bonus functions, payout amounts for symbols, special symbol activations and other aspects. There is also information about the number of payment lines, RTP and volatility. 

RNG Verification 

No punter wants him or her to be cheated. That’s why you only need to play slots from well-known vendors, and only on legal sites. Games are placed on such platforms only after the correct operation of the RNG has been verified and confirmed. The verification is carried out by independent testing agencies. Here are the main organizations whose expertise is respected by gambling operators from all over the world: 

  • GLI;
  • eCOGRA;
  • iTechLabs. 

When studying top slots sites, pay attention to the presence of a verification certificate by these agencies. Otherwise, ask the support agents about whether the integrity of the game outcomes on the platform has been verified. 

Other Aspects 

If you wish and have free time, you can devote time to other details when picking an online slot. These include these aspects: 

  • Slot type (classic or modern);
  • Graphics;
  • Sound;
  • Theme (say, Ancient Egypt or the Wild West);
  • Number of reels;
  • Number of payment lines;
  • The opportunity to win a fixed or progressive jackpot;
  • Presence or absence of special symbols;
  • The opportunity to purchase a bonus;
  • Availability of special mechanics (for example, Megaways), etc. 

Remember that when picking, you can utilize the information on the official website of the game developer. In this case, you are guaranteed to get all the data you are looking for. 

Premium Slot Providers

Hundreds of providers are engaged in creating online slots, but not every one of them can be trusted. When picking a game, as we said above, it is crucial to pay attention to who developed it. It is advisable to give preference to iGaming content of those studios that have been working on the market for many years, have earned superb reputation in the industry and respect from players. Here are some samples: 

  • NetEnt. One of the titans of the industry known for its high-quality and innovative amusements;
  • Microgaming. Another leader of online gambling, which has a fantastic portfolio of games, and, in particular, proposes incredibly generous slots with progressive jackpots;
  • Pragmatic Play. For several years of work, this provider has rapidly burst into the elite of the industry. When developing games, it pays attention to high-quality graphics and unique features;
  • Play’n GO. Slots from this renowned vendor work perfectly on any pocket gadgets. They are characterized by cool gameplay and innovative features;
  • Yggdrasil. Titles from this slot provider are characterized by cool graphics and excellent features, including the use of interactive elements;
  • BetSoft. This top supplier focuses on creating slots with cool graphics and cinematic animations. Its games are available in various themes;
  • Playson. Slots of this renowned firm will appeal to different categories of gamblers, thanks to the diversity of themes, features and styles;
  • Red Tiger. This popular developer proposes both classic slots and modern video variations, full of bonus features and innovative features;
  • NoLimit City. A great example of a studio that has earned an excellent reputation for several years, thanks to high-quality content and unique themes of its slots;
  • Endorphina. Another premium developer whose games are represented in the portfolio of the top-rated slots sites. 

This does not mean that you need to play online slot machines only from vendors who have been working for a long time, and do not trust newcomers. But, if you are interested in games from fresh providers, then take a little time to peruse their biographies.
