Play Online Slots UK - Real Money Slot Games + New Slots


If you're looking for somewhere to play online slots, then look no further!

Online slots are a staple of online casinos, and Kong Casino is no exception! As a result, we strive to ensure our collection is stocked up with the industry's newest and best slot games.

Kong Casino offers over 1,500 online casino games, including slots, table games, instant win games, and bingo!

As per UK Gambling Commission (UKGC) regulations, all our slots here are real money slot games. This means you bet with real money and could potentially win real money. However, nothing is guaranteed, so please gamble responsibly and never bet money you aren't comfortable losing.

Best Online Slot Games

Kong Casino players deserve the best, so we strive to deliver it to them. 

However, this isn't as straightforward as one may think. The best uk casino slots can mean different things to different players; it all depends on what you're looking for. 

Some may say the best slots are the classics that have stood the test of time and are still popular. Others may say it is the slots with the highest Return To Player (RTP) rate, and others may say it's the ones that offer the highest potential payout.

Fortunately, we have all the bases covered. We have iconic slots that are as popular now as they were upon release. We have slots with RTP rates that sit way above the industry average, and we have plenty of slots offering impressive top prizes.

We'll share a couple of examples here. Beginning with some classic online slots:

  • Starburst: A 5x3 slot by developer NetEnt, Starburst was released in 2012 but is still one of the most popular slots today. Featuring 10 paylines that pay both ways, this slot also has an Expanding Wilds feature, a simple yet exciting bonus feature that may also trigger a respin. Stats-wise, it's a low volatility slot with an RTP rate of 96.09%.
  • Fluffy Favourites: Eyecon Gaming presented a challenge for players when releasing arguably their most successful slot, Fluffy Favourites. The high volatility and low RTP rate of 95% may not be particularly generous. However, 25 paylines and a Free Spins feature, where all potential wins are subject to a 3x multiplier, help to make up for this and could explain its sustained popularity.

Here are slots with some impressive RTP values:

  • Zeus Lightning Power Reels: Red Tiger Gaming delved into Greek mythology for this 7x6 behemoth of a slot. As the King of the Gods, whenever a Zeus Super Symbol lands on the reels, he uses lightning to expand the same symbol on a random number of reels. There's also a Free Spins feature and the potential to win up to 4,500x your stake. Most importantly, this slot has an RTP rate of 97.73%.
  • Blood Suckers: This vampire-hunting slot may be quite simple in design, but this low volatility slot has a Free Spins feature with tripled payouts for the duration of the round. It's played on 5 reels and 25 paylines, but the highlight is its incredibly high RTP rate of 98%.

Finally, here are some slots that offer astounding maximum wins:

  • Peking Luck: This 3-reel slot has a Chinese opera theme, which is not common among online slots. However, this isn't all that makes this slot stand out; Peking Luck also has a maximum win of up to 180,000x your stake! This is on top of a Free Spins feature and multipliers, making this a slot that can't be missed.
  • Rome: The Golden Age: Another slot from NetEnt, it's played on 5 reels set out in a diamond formation, where the first and last reels are the smallest and the middle reel is the largest. It has a Golden Frame feature that could cover the reels with wild symbols and a Free Spins feature with progressive multipliers. This high volatility slot has a maximum potential win of 100,000x your wager!

So, regardless of how you define the best online slots, we have something that should fit the bill.

Most Popular Casino Slots To Play

To make sure we are giving our players the best, we make sure we have the hottest slots, the slots everyone is playing. After all, there has to be a reason everyone is playing them!

Here are a handful of the most popular online slots that we offer:

  • Rainbow Riches Pick' N' Mix: An Irish-themed slot played on 5 reels, 3 rows and 20 paylines. This slot also has an incredible maximum win of up to 50,000x your total bet, not to mention 5 potentially rewarding bonus features, so the low RTP rate of 95% and slightly high volatility in Rainbow Riches Pick' N' Mix can be forgiven.
  • Big Bass Bonanza: A fishing-themed slot packed with bonus features, including a Free Spins feature and multipliers. Big Bass Bonanza is a medium to high volatility slot with a lot going for it. It is played on 5 reels and 10 paylines. The wild symbol is also part of a Collect feature and plays a role in potentially re-triggering the Free Spins feature.
  • Dynamite Riches Megaways: This Megaways slot is played on 6 reels, with each reel holding up to 7 symbols, allowing the slot to have up to 117,649 ways to win. That's a lot of opportunities for a winning combination! There's also a selection of other bonus features, such as Mega Wilds, Multipliers, and a Free Spins feature. This medium volatility slot has a RTP of 95.75% and a maximum win of up to 7,000x your stake.
  • Eye of Horus: This ancient Egypt-themed slot from Blueprint Gaming is played on 5 reels and 10 paylines, has a respectable RTP of 96.31%, and an impressive maximum win of up to 50,000x your wager. Eye of Horus also has 2 decent bonus features; a Free Games feature and an Expanding Wild symbol.
  • Wild Wild Riches: Another Irish-themed slot; this one is from Pragmatic Play and is played on 5 reels with up to 576 ways to win. Wild Wild Riches is a high volatility slot with a Free Spins feature and a Money Collect feature that could see you win one of the 3 available jackpots!

These are just a few of the popular slots in our collection. We also have Blue Wizard, Aloha! Cluster Pays, 9 Masks of Fire, and more! Browse our selection to see for yourself.

Play Slot Machines Online For Real Money

All of the online casino games we offer, including online slots, are played with, and for, real money.  

Due to regulations put in place by the UKGC, demo play/free play cannot be offered in online casinos operating in the UK. As such, all of our online slots are real money slots; this means you bet with your own real money and could potentially win real money.

So rest assured, any of the games you choose to play here at Kong Casino are played for real money. However, remember there are no guarantees. So please gamble responsibly, don't chase your losses and don't bet money you aren't comfortable losing.


How To Play Online Slots?

To play an online slot, you have to find an online casino and register an account. Then, make a deposit and select a slot game to begin playing!

Once you've found a slot you wish to play, you should begin by opening the paytable to read all the information provided. This will provide details on the game's rules, the values of different winning combinations, and if there are any bonus features, as well as how they work. 

Once satisfied, you can go ahead and place your bet; this is usually adjusted by using arrows or +/- icons. Then, when you're ready, click Spin and wait to see the outcome.

Are Online Casino Slots Truly Random?

Online slots use a Random Number Generator (RNG) to determine the outcome. It works by generating millions of number sequences each second by putting a seed value through a complex algorithm. The sequence generated corresponds to an outcome on the reels, a combination of symbols. 

When you click Spin on an online slot, the sequence generated in that instant is used and provides the outcome you see on the reels. The sequences are completely random and cannot be predicted.

In addition to this, each Spin is an independent event. Previous spins have no bearing on the outcome. So, a slot has just as much chance of paying out the maximum win twice in a row as it does of not paying out the top prize for a month or longer.

What Is RTP (Return To Player) In Slots?

Return To Player (RTP) is the slot's theoretical payout percentage. What this means is it is the rate at which the slot should pay out over time. 

It is given in the form of a percentage, and it is the theoretical amount of the money taken in by a slot that can be paid out to players. So, for example, a slot with an RTP of 96% will, in theory, pay out £96 for every £100 it takes in. However, there is no telling which players this will be paid out to, nor how much of it they will receive. 

The RTP is calculated over a vast number of simulated spins by the developer. So, in a short gaming session, it may not be reflected. You may receive more, or you may receive less. It is merely an indication of how the slot may pay out in the long term.

Can You Win Real Money On Slot Games Online?

Yes, the UKGC no longer allows demo/free play, so all online slot games available in the UK have to be played with real money. Therefore, you could potentially win real money.
