There’s little doubt that online slots remain as one of the most popular casino games. They’re fun, come with various themes included in them, incorporate special features and have the potential to provide some really nice pay-outs as well. What’s not to love about that?

Not only that, but there are different varieties of online slots that are available for players to access as well. Therefore, they do cater to a range of casino gamers as well.

Classic Slots

If you ever hear the term ‘classic slots’ being used, then the likelihood is that it’s referring to those slots that were traditionally found in land-based establishments and arcades.

These often come with three reels included in them and most of the time, have no more than five paylines for you to bet on. In brick-and-mortar establishments, they would often have a lever to pull in order to set the reels off spinning, too.

While that lever doesn’t appear in online classic slots, everything else associated with them does. So, you’ll see a much more basic online slots with these.

Video Slots

In comparison to classic slots, the video slots exist as the more modern variations of the games. These frequently come with five or more reels to spin and tend to incorporate much more in terms of special features and betting customisation options.

Not only that, but they usually incorporate high-quality graphics, and today, they exist as the primary output of software developers where slots are concerned.

Jackpot Slots

For those players who like to give themselves more of a chance at winning a huge amount, jackpot games are the way to go. Over the years, jackpot slots have changed, with many now incorporating two, three, four, five and more jackpots for players to be in with a chance of winning.

Progressive jackpot slots are also in existence, with the jackpot totals increasing every time someone places a bet on the slot. It’s also more often the case that jackpot slots operate in the same vein as video slots, but with larger winnings available.

The Major Millions casino fruit slot offers this amazing progressive jackpot which players can win by lining up five of the logo symbols across the middle win line.

The theme of the major millions game is based on a charismatic armed forces major and is presented with a stunning style of cartoon animated effects.

The range of fruit slots online all utilize a different selection of effects to deliver their themes to players. The more advanced fruit slots online offer a fantastic selection of visual and sound effects which players will love as they are very engaging and attractive.

How Do You Win Money on Online Slots?

It would be simple enough to just say that you place a bet, spin the reels and wait for the outcome with regard to how to win. And yes, this is generally how a slot machine works, regardless of whether videos slots, jackpots or classic slots. Yet, there are certain other things which we think you should also take into consideration – especially when it comes to playing the best online slots.

We’re not saying that these will ensure that do win money on your chosen slots. Instead, we’re saying that when you play slots, you should take a look at how good they are in terms of the following inbuilt features. And this doesn’t just relate to online gaming, but to land-based casinos as well. So, here are some things to look out for in a bid to get yourself closer to winning when playing online slots.

Always check the RTP Rate

Not many people who access casino sites or enter land-based casinos will be too well-informed on the RTP rate of games. Instead, it’s more common to just see a great theme and access the slot game. And while it’s great to always play the best online slots with an appealing theme behind them, you need to have a little bit more information regarding its potential rewards. That’s where the RTP rate comes into effect.

The return to player (RTP) rate of an online slot will always be a clear indicator of how much you can expect to get back from playing a specific game. This is given as a percentage amount, although keep in mind that this amount is calculated over a long-term period of playing. So, if the return to player rate is noted as being 93%, then you can expect to get around this amount of your bets back over thousands of spins.

The average RTP rate of the best online slots today is around 96%, so if you can find an online slot with more than this, the odds are slightly more in your favour. Fortunately, some of the best slots to play online come with very high RTP rates of around 98% and even up to 99% in some cases. Check this out before you go ahead with playing a slot game, as it’s some relevant information to remember.

Look at the Volatility Level of the game

Does the game you’re playing have a high volatiliy rate or a low one? This is another question that many players don’t ask themselves before accessing an online slot game. Yet, if you’re looking to access the best online slots for you, it’s necessary. Why? Because the higher volatility slots will provide bigger payouts, but on a less-frequent basis. The opposite is true of the low volatility games.

So, you really need to decide what kind of slot games you want to play based upon their volatility, too. Generally speaking, it wouldn’t be so good to access a highly volatile game when you have a balance of around €20 to bet with. After all, if you’re going to be placing lower wagers on these real money games, then you’ll only receive wins every so often. Granted, these will be slightly larger than what would be the standard from slots, but you can’t sustain gameplay on such slot machines with that kind of bankroll.

Keep a Cool Head 

This isn’t the be all and end all, but it’s a good piece of advice to take with you into slot gaming. The best online slots will be entertaining, incorporate wonderful bonus features, allow you to engage in free spins and provide you with exceptional bet ranges. Yet, this is all for nought if you’re going to get angry and upset whenever you suffer one or two losses. The idea when accessing online slots is that you keep a cool head and that you have fun spinning their reels. That’s why online casino sites provide such a wide range of these games, in general.

However, gamers are known for placing bets and then seeing a few losing rounds occur one after the other before falling into despair. A slot should be played with the mindset that you’re not going to win everything you bet. And if you find yourself getting upset and angry at those moments, you’re likely to gamble away all your funds without garnering much back from the games. Remember – higher volatility level games are much more likely to have several losing spins after the other than lower volatility slots.

Online slot machines are full of flashing lights, entertaining themes and inbuilt sounds that make everything come together perfectly in most cases. Just don’t allow this to overwhelm you and push you toward making wagers that you’re uncomfortable with placing. Be calm, cool and collected.

Playing Online Slots with an exclusive Casino Bonus

Online casinos may not be the only locations where slot games can be found, but they are the only places that provide casino bonuses for you to utilise alongside.

These give you the opportunity to benefit from additional funds or even free spins on your favourite slots.

Bonus funds can be provided in two ways – first of all, they can be given as no deposit rewards or as a perk on top of a deposit. These funds can often be used on any game within the lobby, although slots are often the go-to game for many people where bonuses are concerned.

Bonus funds can be given to newcomers and regular players as well. So, you may see promotions that are written in the vein of, “Deposit at least €20 and receive a 100% bonus up to €100”.

With regard to free spins, these focus solely on slot games, as they’re unable to be used on anything else. Free spins basically describe what they are in their title – free spins of the game’s reels.

Again, these can sometimes be given as a reward without you needing to make a deposit at an online casino, or they can be offered once you transfer money into your account. Therefore, it may be possible for you to find rewards like, “Deposit €20 and receive 50 free spins on Book of Dead”, for example. Furthermore, bonuses and free spins can often be provided in a promotion together.spinia promotional banner image

Exciting bonuses for New Players

It’s a common practice of many online casinos to welcome their newly registered players with exciting bonus rewards and promotional offers. This way, you’re more compelled to play their video slots and so on. This is why you’ll often find such sites giving away bonus funds and free spins on top of your first deposit. Otherwise known as a welcome bonus, this sees new players make their first deposit (and sometimes second, third, fourth and so on), and as long as they make the minimum qualifying transaction, the rewards will be added to the casino account, too.

In fact, some of the best online casinos provide the greatest bonus rewards as well. It’s not uncommon for the welcome bonus to be advertised on full display via the casino’s homepage. This way, it captures your eye from the get-go. A casino needs players to register and deposit and start playing games to ensure that it at least has some activity occurring and its own revenue at the same time. Yet, some of the best slot gameplay can come from utilising a bonus.

So, if you make your first deposit at your chosen platform as one of its new players, be sure to check into the qualifying deposit in order to receive the bonus rewards. Frequently, online casinos will give away both bonus funds and free spins within these rewards. It’s important that you read up on the terms and conditions relating to a welcome bonus, though. These dictate certain rules to you surrounding the reception of such and how you are able to make a withdrawal once you have received it.

What does Bonus Wagering Requirements means?

As part of the terms and conditions noted previously, online casinos should also inform you of the wagering requirement related to the bonus received. New players may not be aware of what this is in general, so we’ll give you a bit of an insight. When you receive a bonus reward from a gaming site, the best online casinos will also make it very clear what the playthrough requirement is. This describes the number of times that the bonus funds you have received need to be wagered on games at the platform.

So, if you see wagering requirements in the terms and conditions that exist as 30x the bonus amount (and sometimes it will be applied to the deposited amount as well), then you know that this is the sum of bets you must place. So, let’s utilise a bit of an example to further decribe this. Let’s say that you deposit €50 for a 100% bonus up to €100. Naturally, 100% on top of €50 is another €50, meaning that you’ll start your real money gaming with €100 in total. Using the wagering requirement figure from previously, you would need to place bets equating to €50 x 30 on casino games. This means that your wagering requirement would be €1,500 altogether. You can play slots to be able to cover this, as most of the time, these contribute 100% of your wagers towards such.

In the case of the wagering requirement being applied to your deposited funds as well, you’ll need to complete wagering of €50 + €50 x 30 = €3,000. The best online slots sites will provide you with attainable wagering requirements for their bonus offers, so this is something else to consider when looking for a new casino site to sign up to and play at.

Some most popular Software Providers

The online world is lucky in the sense that it has so many developers creating slot games. Of course, some of these are much more popular than others for various reasons. This could be due to their graphics, the inbuilt features of the slot games, the betting options available within, the innovative side or even the themes used in such.

Some of the most popular software providers include Netent, Amatic Industries, Play’n Go, Microgaming and Betsoft.

The Best Online Slots 2020

While there’s a huge number of slots available to play online, some of the very best online slots on hand include the following titles:

book of dead logoBook of Dead

Also known by its full title of Rich Wilde and the Book of Dead, this slot game is perhaps the most famous one from the Novomatic brand. It utilises a setup of five reels and three rows, whilst also incorporating 10 paylines.

Many players consider this as one of the best online slots ever made.

The theme running through it is one of Ancient Egypt and incorporates a scattered wilds symbol that can lead to a free spins round.

Book of Ra Deluxe

Another Novomatic game released, Book of Ra Deluxe also features a five-reel, 10-payline setup. It operates as a sequel to the original Book of Ra release, and it has many of the same features as the Book of Dead slot.

Essentially, it follows an explorer through the lands of Ancient Egypt. Again, the book symbol operates as the scatter and wild in this best online slot, which is also able to trigger free spins.

This slot is perhaps the most well-known from Netent, which could be primarily thanks to the simplicity of it. The graphics, as always, are of the best quality from this developer, and the reels feature stacked wilds in the form of stars on its central three reels.

A re-spin is triggered when stacked wilds form on a reel, and wins can be formed from left to right and right to left throughout.

Gonzo’s QuestGonzos quest logo

If you’ve heard of the tales of El Dorado, well, you’ll get to go in search of those lands with Gonzo in this Netent slot. Utilising wonderful features, such as the avalanche reels, the increasing multiplier and a free falls round, this is definitely a game that will stay with you from the moment that you first play it.


Dead or Alivedead or alive logo

In Dead or Alive, you’ll get to visit the Wild West and place bets on nine paylines across a five-reel, three-row setup. While only incorporating a couple of intriguing special features, these are present in the shape of the wild symbol and the scatter.

Sticky wilds are present during free spins, which is triggered by three or more of the pistol symbols coming into view anywhere.

Most commonly seen bonus features in slots online

Within many online slot games, additional special features are included to add to the overall entertainment value of them. These are much more prevalent in video slots and jackpot slots, but some of the more commonly seen features in games include:


Wild symbols are probably the most commonly seen inclusion in online slots overall. A single symbol will usually be singled out to operate as the wild, and whenever this one appears, it has the ability to substitute for all other standard symbols on the reels. Therefore, the wild is quite helpful when it comes to forming winning combinations.


Scatter symbols are included in slot games and can appear in any location but still reward you with a pay-out. Therefore, you don’t need to get three symbols on a payline. Instead, you can benefit from spinning three of them into view anywhere and still get a reward for it.

Free Spins

What’s always great to find in online slots is a free spins round. Basically, this allows you to spin the reels of the game without utilising any of your own funds for doing so. These also tie-in with the scatter symbols mentioned previously, as often, it takes three or more of the scatters to activate a free spins round.

What’s more, the free spins can at times introduce additional special features for throughout the round.

Bonus Round

Bonus rounds are also present within online slots at times. These can come in various formats, including pick and click (which simply require you to click on any of the items on screen and receive a reward for such), wheel of fortune (requiring you to spin the wheel and receive a pay-out for such) or theme-specific rounds.

Jackpot Games

Within jackpot slots, there will sometimes be a specific bonus round dedicated to the jackpot(s) on offer. So, if you’re not required to form a specific win in order to win one of the jackpots, then a bonus round is likely to be in operation for it instead.

These can include the aforementioned wheel of fortune taking you from one wheel to another in the hopes of winning a jackpot through such or even theme-specific rounds.

Gamble Rounds

The last common feature to be found in some online slots is a gamble round. These will usually always activate after you form a winning combination across the reels. Should you decide to play the gamble round, you stand the chance of doubling or even quadrupling the win amount from the triggering round.

Gamble rounds can come in various formats, but one of the most frequent is a card game. This simply requires you to guess the colour of a face-down playing card between red and black to double the win or guess its card suit in order to quadruple the win.

Things to Consider When Registering to Play Slots On Line

To be able to access real money slot games, and in the process some of the best slot games too, you’ll need to be registered at at least one online casino. Naturally, we don’t recommend that you simply register for an account at the first casino you find. That would be a bit of lunacy. Instead, a casino should meet all your requirements as a player. And this doesn’t simply mean that you should find one with a good bonus offer, either. Games make up part of what makes a good gaming site, licensing is important, the site design is something else that should stand out, and so much more. So, we’re going to take a look at a few of the things to look out for when accessing a casino site.

Licensing and Regulation

One of the most important parts of a casino site is that it holds at least one high-quality gambling licence. For new players, this is especially important to keep in mind. As a new player, you may be considered a little bit more vulnerable, so make sure that you understand if a casino is licensed or not before signing up. The online slot machines may be of a huge temptation to you, but without a gambling licence, a casino can do as it pleases with your funds and your safety could be compromised.

Some of the more secure gambling licences include those from the United Kingdom Gambling Commission, the Malta Gaming Authority, Alderney Gambling Control Commission and Gibraltar Regulatory Authority. It’s also relative to note that a casino operating online should feature an all rights reserved note, meaning that it is licensed and that the owner gives its permission for registered users to access the casino games, including slots.

General Design and Lobby

The basic design of the casino should provide an easy platform to navigate around from start to finish. Games should be easy to locate, the lobby should be well-designed and there should be categories for you to browse around the best slots and other casino games. There’s no point in registering for a gaming site that doesn’t cater to players in terms of design and functionality.

Range of Slots and Games

As gamers, we like to have a diverse range of titles to access, right? Well, be it new players or regular gamers, there needs to be something for everyone at the best casinos. So, check the lobby out to find which developers provide their slots, what types of slots are available to access, how many of the slot games come with added bonus rounds and such. After all, you’re going to be one of the players there, and it’s important that you get the most from your spins. This doesn’t just mean that you should experience win after win, but an exciting and entertaining session of slot gameplay.

Of course, see how diverse the slot games themselves are within the lobby. If the real money slots exist solely in the form of classic slot titles, then it can’t be said that the slot machine range is wide, can it? We want to see video slot titles, progressive jackpot slot games, video slots and more. This is a feature that makes up the best online casino site.
