How to find the best Slot Games Online?

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 slot 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 about 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. Still, 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 their 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 no specific set of skills required for playing slots, but it will be good to 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 will claim our bonus spins. Our welcome offer carries specific wagering requirements, which, if you think you can meet – are 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!

Slot Machines

After you finish your bonus 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 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 easily catch up to the gameplay; 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. Our favourite classic slots are:

  • Fluffy Favourites
  • Shamans Dream Deluxe
  • Fire Joker
  • Rainbow Riches

Fruit Machines

The sibling to classic 3-reelers is the renowned traditional fruit machine. Although bars, sevens, and fruits were the first symbols that slot machine games carried – they persist in 2021. Software providers approach traditional fruit machines and turn them into state of the art online slots. A few amongst our favourite are:

  • Diamond Strike
  • Fruits & Jokers 100 lines
  • Fancy Fruits Respins of Amun Re
  • Da Vinci Diamonds
  • Reel King

Video Slots

Most of our newer video slots, though, tend to have over 25 paylines and a 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 slot 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! Some of the best video slots to date are:

  • Divine Fortune
  • Gonzo’s Quest
  • Book of Dead
  • Fishin Frenzy
  • Rainbow Riches Pick n Mix

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 types of progressive jackpots that you can encounter in our slots include Jackpot King, Fire Blaze Jackpots, Power Play Jackpots, fixed, daily, and monthly pots. There are different prizes as a chance to win the various slot games with jackpots, while some of the best are listed below:

  • Mega Moolah
  • Temple of Iris Jackpot
  • Mega Joker
  • Mega Fortune
  • Wolf Gold


Are you tired of all the classic slots and 5×5 reelers? Go with our MEGAWAYS slots that offer over 100,000 ways to win on every spin, with potential winnings of 50,000x the players’ bet. When playing ways to win or MEGAWAYS slots online, punters won’t have to set paylines; matching 3 symbols on adjacent reels is all it takes to land a win! The most popular MEGAWAYS slots, thanks to the Big Time Gaming engine, on King Casino are:

  • Piggy Riches Megaways
  • Fluffy Favourites Megaways
  • Dog House Megaways

What are the Best Online Slots to Play?

Finding the best slots online is challenging due to the extensive range of options; our promotions page is a great place to start; however, we have secured exclusive bonus spins for the best-rated UK gambling slots.

Considering slot players’ choices of the years and the RTP, volatility, bet levels, payouts, and graphics – we have listed the most popular slots in 2021.

Book of Dead Slots

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 help you get big gains, and it utilises a new symbol feature. It has a high RTP of 96 per cent. A symbol is randomly chosen to trigger your bonus spins and becomes a special expanding symbol.

Low volatility and inviting bet levels are apparent in Book of Dead, which contribute to its success. Play’n Go would not be where it is today without this title amongst their ranks.

Asgardian Stones Slot Game

A bold choice amongst online slots, Asgardian Stones has a lot to offer and is one of NetEnt’s best slots to date. The storyline is fun, based on Norse mythology, and the theme is elevated as the game looks brilliant. In terms of features, this choice of video slots can boast the avalanche feature so that 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. Play Asgardian Stones and more slots with over 97% RTP on King Casino today.

Bonanza MEGAWAYS UK Slot

Bonanza is one of the most fascinating games you can play online, and that’s a fact. Big Time Gaming developers have released it, and it was the first to offer 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 row to score a win—the more symbols in total, the highest the payout.

GOLD is the word you need to form using the 4x letters on the reels. Hitting these 4 letters will take you to the Bonanza bonus round, one of the most lucrative ones in the whole industry. You start with bonus spins ranging from 9-25, increasing 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. With a max win at 10,000x+, you should get spinning right away!

Twin Spin Game

Similar to the gameplay of Starburst, Twin Spin resembles classic fruit machines. However, the gameplay in this slot 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 coins, with 1-10 levels available. The values of the coins can be altered, allowing players to minimise or maximise their bets. Play it today

How to Win at Online Slots?

Winning at online slots is not hard, but it can’t be achieved purely due to 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. Licensed casinos are also a prerequisite, as these are the ones you can trust.
  • 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. Blood Suckers, for instance, carries a 98.2% RTP.
  • Pick a High Volatility Slot – this means that the slot game of your choice is paying high prizes, even if that means that the payouts are less frequent compared to low volatility slots.
  • Pick a Slot with Multiple Bonus – make sure to find a slot game with at least 2x different bonuses. These do not include scatter and wild symbols, but bonus rounds, jackpots, multipliers, sticky wilds or all of these! A bonus that combines multiplier and bonus spins is probably the most lucrative, as the one offered by Gladiator Jackpot slot by Playtech.
  • 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, you would likely make some money the next time. Also, remember not to bet over 1 – 3% of your total bankroll per spin; otherwise, you could lose within minutes.
  • 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 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 you can take our word for it.

What are the most popular questions about online slots? (FAQs)

We have tried to break down some common misconceptions related to slots and offer you our insights to only experience our casino in the best possible way.

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 the rewards are magnificent when they do.

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 likely 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!

How to find the best slots games in the UK?

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 about the game itself.

Are the Slot Machines Rigged?

If you choose to play our slots, King Casino guarantees none of them are rigged. Licensed through the MGA, all our casino games go through regular RNG checks. Our license proves that we offer fair and safe online slots, all operating as the software providers behind them devised to do.

Do Online Casino 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! Considering the return to player rate, volatility, jackpots, bonus features, and bet levels in online slots is the only way to get an idea of what to expect.
