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 slot 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 slots 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.

Playing Online Slots with a 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


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.

Best Online Slots 2020

While there’s a huge number of online slots available to play, some of the very best slots online 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 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.
