Accessing Online Slots at King Casino

With hundreds of online slot games to choose from here on King Casino, it’s about finding a slots title that fits your preferences the best. Whether that’s the style of theme you are looking for, the number of reels or bonuses, we got it all covered!

For those who have never played online slot games before, we advise that you take the opportunity of testing out various slot games via the demo mode available on our online casino. By doing this, you can get a good feel for the game from a visual aspect without depositing any real cash. For a specific selection of games, we also offer in-depth game descriptions produced by professionals within the industry; these outline everything you need to know in regards to the game itself and how to play it.

It doesn’t take a gambling fanatic to realise how far the slot machine has come, it’s an original simplistic appearance that merely consisted of reels, and a button was what made the game so popular in the first place, but now with the added aspects such as in-game features and bonuses, it has made slot games that bit more worth playing. Slots may not hold the structured way to winning like that of table games, but it’s unpredictability and variation sure beats many on that front.

How to Play Online Slots

Playing online slots is easy, as long as you join the right site for you. There is not some specific set of skills required for playing slots, but it will be good if you have some personal traits, such as persistence, patience and an ability to make quick decisions. At King Casino, the first decision you will have to make is whether you are going to claim our bonus spins. This carries specific wagering requirements, which, if you think you can meet – they are definitely a bonus asset. Your bankroll will be safe as long as you stick with these. Below, we detail the different types of online slots that we offer, so you get an idea of what to expect and how to play them!

Classic Slot Machines

After you finish your free spins on Starburst and Book of Dead, it is entirely up to you to which of our 600+ slots online you will play. These differ in terms of theme, minimum and maximum bets, symbols, bonuses, graphics and music. From our long list, you will be able to find one that fits exactly your taste. If you decide to play a classic fruit or slot machine, you will catch up to the gameplay pretty easily; these have 3×3 reels structure and no bonuses. Matching a minimum of 3 symbols will grant you a prize, which increases the more same symbols you match.

5×5 Reel Slots & 25 paylines

Most of our newer video slots, though, tend to have over 25 paylines and 5×5 reel structure. Some even have coins betting instead of real money betting. We would advise you to start by betting on a single payline to see how the game rolls before you move on to add more. You can read our reviews or the information page to learn about the bonus rounds and symbols, or you can let the online slot surprise you!

Jackpot Slots

Another popular category with punters is the jackpot one. Although normal slots tend to pay 500x your bet at times, jackpot slots go even further than that. Types of jackpot slots include the minor, major and grand, which are adjustable to your betting amount. Progressive jackpot slots are also available at King, which have a prize that constantly rises until a player wins it.

Other Slot Types

If you get familiar with all of the above categories and want to try something different, then you can turn to games that follow alternative reel & payline structures. Megaways, Megaclusters, Infinity Reels, Scatter Slots, Sticky Surprise slot games and more types of games are available on King. Try them to see what all the fuzz is about.

For the best online slots, look no further than King Casino. We have everything you need for an epic gaming experience that you can enjoy and play from the comfort of your own home.

Picking the best slot machine to play online is not easy, so we have briefly touched upon a few of the more popular ones in today’s online slot world!

#1 Book of Dead 

Why not try one of the top slots at King Casino? And with one awesome bonus feature, it’s as straightforward as slots come. The bonus feature with the Book of Dead is in the form of a bonus spins feature. This brilliant bonus can really help you get big gains, and it utilises a new symbol feature. It has a high RTP of 96 per cent. To trigger your bonus spins, a symbol is randomly chosen and becomes a special expanding symbol.

There are loads more slots to enjoy at King Casino, and sign-up has never been easier. Just log in and get your spin on no matter where you are, no matter what device you’re on. Happy slot gaming!

#2 Asgardian Stones Slot

A bold choice of online slots, Asgardian Stones has a lot to offer and is one of NetEnt’s best online slots. The story is fun, based on Norse mythology, and the theme is really elevated as the game looks brilliant. In terms of features, this choice of video slots can boast the avalanche feature, so players can get multiple wins from every spin. Available to play at this brilliant online casino

There’s also a special symbol in the form of the colossal symbol, which activates the colossal crush feature – whereby the special symbol crushes rows of symbol and increases the multiplier. The multiplier increases from 1 up to 4x, but the main attraction is the bonus wheel feature, where you can win cash prizes and up to 25 bonus spins. There’s no need to worry either, as all our slots are licensed and regulated.

As for jackpot slots, we offer some of the best you can find out there, and you can play to go for gold with bonus spins even with these slot games. Find the iconic title Rainbow Riches for the chance to take home some epic gold prizes, and we have plenty of other slots which offer amazing gameplay and bonus spins rounds which give players great value. We’re certain you won’t have more fun with our huge range of slots elsewhere, and King Casino prides itself on upholding the gold standard of slots. If you want to game with the best slots, check out our range today to find a choice to play that’s right up your street.

#3 Bonanza Slot

Bonanza is one of the fascinating games you can play online, and that’s a fact. It has been released by Big Time Gaming developers, and it has a Megaways structure. This means that the symbols do not need to match in a particular order. Here, you just need to have the same symbol on every single row to score a win—the more symbols in total, the highest the payout.

GOLD is the word that you need to form using the 4x letters on the reels. Hitting these 4 letters will take you to the Bonanza bonus round, which is one of the most lucrative ones in the whole industry. You start off with free spins ranging from 5-25, which can increase during the bonus round. Each combination of symbols that you much increases your multiplier, without any cap. This means that the wins at Bonanza could even exceed jackpot levels.

#4 Twin Spin

Similar to the gameplay of Starburst, Twin Spin resembles classic fruit machines. However, the gameplay here is much smoother, the graphics are splendid and the payouts can be very high. With Twin Spin, punters have 243 different ways to win, with the Wild symbol increasing your chances further.

On the 5 reels available in Twin Spin video slots, players can also expect the Twin Reel feature – which can appear on any given round and increase their winning chances further. Bets here take place in the form of coins, with 1-10 levels available. The values of the coins can be altered to, allowing players to minimise or maximise their bets.

How to Win at Online Slots

Winning at online slots is not hard, but it can’t be achieved purely due to the use of a specific strategy. Believing the opposite would be naive, as all casino games require some luck and are always rigged towards the casino. However, there are a few things that you can to increase your chances to win at online slots:

Pick a Good Slot Site – this means that there is some bonus spins offer in place with low wagering requirements.

Pick a Slot with High RTP – brick and mortar slots had an RTP of 75%-85%, but nowadays, players can access many slot games with over 96% Return to Player percentage.

Pick a High Volatility Slot – this means that the slot game of your choice is paying often, even if that means that the payouts are a bit lower compared to low volatility slots.

Pick a Slot with Multiple Bonus – make sure to find a slot game that has at least 2x different bonuses. These do not include scatter and wild symbols, but bonus rounds, jackpots, multipliers, sticky wilds or all of these!

Stick to your bankroll – decide in advance how much you want to spend and stick to that amount. Even if you didn’t win today, it is likely that you will make some money the next time.

Make often withdrawals – when you have raised a good amount of cash, it is wise to transfer these out of your casino account. This way, the next time that you want to play, you will start with a normal bankroll amount and won’t overspend.

Sticking to the above points will massively increase your winning chances at online slots. We are open about our games, and we want to offer a healthy and fun experience to all the players, so take our word for it.

Slots Frequently Asked Questions (FAQs)

We have tried to break down some common misconceptions and also offer you our insights for the best online slots experience:

What Slot Machines have the Best Payout?

For the highest possible payouts, players should focus on jackpot slots – and in particular progressive jackpot slots. These are rarely paying out the maximum possible win, but when they do, it can be life-changing. If, on the other hand, you are looking for the slots that payout more often – you will need to find high volatility slots with an RTP of over 96%. Most slot games on King Casino have an RTP of 90%-97%. Stick with those, and you will land many payouts!

How Can I Increase my Chances of Winning on Slot Machines?

There is no winning strategy for slots online, as all legit online slots sites have an RNG in place. This means that each spin is randomised and completely irrelevant to the previous one. However, picking a slot with a high RTP and playing on a busy online casino could massively increase your winning chances on slots. Bonus features, bonus spins and casino welcome offers are also good additions that can increase your winning slot chances!

Finding the right Slot Online

With hundreds of slot games to choose from here on King Casino, it’s about finding a slot that fits your preferences the best. Whether that’s the style of theme you are looking for, the number of reels, the ways of winning or the bonuses and features that the slot offers. For those who have never played online casino slot games before, we advise that you take the opportunity of testing out various slot games via the demo mode available on all of our games.

By doing this, you can get a good feel for the game from a visual aspect without depositing any real cash. For a specific selection of games, we also offer in-depth game descriptions produced by professionals within the industry, these outline everything you need to know in regards to the game itself.

Are the Slot Machines Rigged?

If you choose to play our slots, King Casino guarantees none of them are rigged. You can find many slots under one roof, and while we have Ts and Cs in place, it’s with all your rights reserved, so there’s no need to worry. We imagine that a rumour of slots being rigged occurred early no in the slot boom when everyone was competing to be the greatest slot-maker around. You can find a range of our slots with amazing reviews and excellent RTPs, so you know they’re paying out.

Do Slots Require Strategy?

If you are looking to get the highest payout, bear in mind slots are mostly based on lucky wins rather than strategy – there are other casino games for the latter. Slots are among some of the most fun casino game options purely for this reason, and it’s always a surprise to lose – and win! Why not check out our huge range and see what you can find?
