Last Updated: 01/08/2023

On this page, you'll find:

Whether you’ve ever played online slots before or not, you probably know how fun they are. They have imaginative themes and interesting bonus features that cannot be found in land-based casinos. The popularity of online slots is increasing, so new online slots are being launched every week. That’s why we’ve dedicated this page to share with you the newest slots in the industry.

At SlotsWise, you’re going to find reviews for all the latest and upcoming slots. We try to test them as soon as they’re announced, sometimes even before they’re available to the players.

We test the gameplay, variance, RTP, graphics, bonus features, betting options, and more. Then, we include this information in our reviews so you can learn more about a slot you’re interested in playing and can make a decision whether the game is worth trying out or not. If there is some information that is not available to us at the moment, we include it in our reviews later when the provider publishes it.

We are constantly on the lookout for new online slots so you can be up to date with all slot trends on the market. New online slots 2023 have great themes and innovative bonus features. What’s more important, they’re mobile optimised so you can play at home or while you are on the go! How great is that?

With thousands of popular slots to choose from and exciting new games being released very often, the number of online slots keeps getting bigger and bigger. So, whether you’re an experienced slot player or a newcomer to the slot industry, check out the newest online slots and see if there’s something for your taste!


New Online Slots Coming in September 2023

Keep an eye out for the following new online slots UK that will be released in September 2023:

How We Rate The New Online Slots

Our team of experts at SlotsWise makes sure that we recommend the best new slots on our site. For that reason, when reviewing a new online slot game, we stick to high standards and check if the game meets the following criteria:


Slot Features

First of all, we launch the game and start spinning its reels to test the basic slot features. This includes the minimum and maximum bets that you can place. Every player has a different budget that can spend on slots, so it’s important that the game’s betting range is suitable for the player’s budget.

Next, we check the paytable, to find both high-paying and low-paying symbols, as well as to read the gameplay (how to activate bonus features, how to land winning combinations, etc.). Finally, it’s very important for us to see how many active paylines the game has, so we can share that information with you in our slot reviews.


Bonus Features

From complex games to simple three-reel slots, bonus features can bring a whole new world to your gameplay. One of the most loved features among the players is the free spins feature, as well as other bonus rounds activated by wilds, scatters, and multipliers.

For that reason, we always check if the new online slots 2023 come with particular bonus features. If there are some features, we make sure to test them and see how frequently they can be triggered. We explain this in detail, so you can easily learn how to activate a bonus feature even before you start playing the game. Plus, we always check if the game includes some jackpot or a mini-game inside it that adds to the whole gaming experience.


Reel Layout

Online slots come in all shapes and sizes. When online slots were invented, there were only the most basic three-reel slots available at online casinos. Nowadays, software developers are more creative and they’re making all types of reel layouts, such as five-reel and grid slots. Moreover, new online slots 2023 have gone way beyond the fixed three or five reels.

Now, there are many slots that work in crazy ways to boost the player’s winnings, so you can find, for example, cascading reels. There are also many ‘Megaways’ slots available where the reels change on each spin. Interesting, right? New online slots UK can be very innovative. That’s why we always check the reel layout of a slot game and make sure to share that information with you.


Design and Graphics

New online slot games come in a variety of themes that enable you highly diverse gaming experience. At one point, you can spin the reels in Ancient Egypt and in the next you’re in a pirate ship going for an adventure and discovering a whole new world. There are literally slot themes for everyone.

Today, we have plenty of different slot themes including fruit slots, 777 slots, space slots, music slots, sports slots, fantasy slots, animal slots, Egyptian slots, fairytale slots, mystery slots, Megaways, history slots, and more! Every new online slot brings you to a completely different place thanks to its design and graphics, as well as sounds that make the game more realistic.



Apart from the features and designs, there is an important metric that determines how the slot is going to payout. It’s the RTP which stands for Return to Player and is always displayed as a percentage. The RTP describes the amount a slot pays back to the players over a large number of spins. The RTP percentage that comes with a particular slot is the result of a calculation based on the result of thousands to millions of spins on the game.

It’s not a guarantee of what you can win from the game, but just an idea of the amount you can expect to win over time. For example, if you play a slot with 95% RTP, it means that the game will give back £95 for every £100 that goes into it. Many players take RTP into consideration when choosing the next slot to play, so our reviews always include this information so you can know what to expect.



The variance, also known as volatility, basically tells you how frequently you can land winning combinations and what will be the size of your winnings. New online slots UK are classed as having low, medium, or high variance. For example, if you play a slot that doesn’t land wins very often but has the potential for bigger prizes, that means that you’re playing a game with a high variance.

On the other hand, low variance slots will pay out smaller prizes on a regular basis. The medium variance slots are the most common type of slots found at online casinos because they’re a great balance between the two extremes. That’s why we always test the new slot games to see how often they pay out and we make sure to include this information in our slot reviews.


Mobile Compatibility

If you want to play a slot game on the go, then you need to make sure that the game you’ve chosen is mobile-friendly. Nowadays, almost all new online slots are developed with HTML5 technology which enables them to be accessible on mobile devices, via mobile browsers, so this shouldn’t be a problem.

During our testing, we always check how the game works on different mobile devices and operating systems to see if there’s something missing compared to the desktop version. It’s important for the game to play fast and smoothly on any device.


Free Play

Due to the increased number of online slots and the competition among them, slot providers release free play or demo versions of the games. Therefore, players who are starting their online slots adventure or want to test out a slot game before playing it for real money can try these free play versions. Free play slots give players an idea of what they can expect from the real-money versions.

All features and elements of the real-money versions are available in the free play except for the fact that you can’t win real-money prizes. 


New Slots Vs. Popular Slots

Can't decide between playing a popular slot game or a new online slot? It can be difficult to find the right online slot, so here are some key points of both new and popular online slots.


New Online Slots

  • New bonus features that you’ll need to learn;
  • Available on mobile devices so you can play them from anywhere;
  • High-quality designs and graphics, accompanied by different themes;
  • Some online casinos might offer a bonus to the new slot.

Popular Slots

  • There aren’t innovative bonus features, some of them don’t even have one;
  • You know the game inside and out;
  • Many online casinos offer bonuses to the most popular slots;
  • You always know exactly what you’ll get.

Popular Slot Providers

Slot providers make the new online slots come true. They create high-quality and innovative slots that meet players’ expectations. Just like slots, the number of slot providers is huge and they are competing with each other to provide the best new slots on the market. As a result, we have plenty of top-notch slot providers that can be found at many online casinos.


Best Online Casinos With The Latest Slots

Luckily for you, we have the list of top-rated online casinos that are updated with new slot titles on a daily basis. Feel free to check them out and make your pick.

All of the online casinos that we recommend at SlotsWise are reliable and trustworthy, and here you can read our process of reviewing them.

Good luck spinning the reels of the most innovative and wonderful new online slots!


Supporters of Responsible Gambling

We take pride in helping our readers find the most trustworthy and reliable online casinos. All of the casino sites recommended at SlotsWise offer a safe and secure gaming environment to their players. All casinos on SlotsWise are regulated by the UK Gambling Commission, so no matter which online casino you choose, you can rest assured that you are in safe hands. 

Although we don’t allow anyone to actually play games on this site, we do work with a list of partners that accept and allow real money gambling online. It’s always important to remember that Gambling in any form should really just be for fun.

The moment you stop enjoying it is the moment you need to stop playing. We are conscious of the fact that anyone who reads one of our reviews and then wants to try out the latest online slots, may deposit with one of our partners, and with that in mind, you must be mindful of the signs that gambling can cause problems.

If you need help and or advice in stopping your online gambling activities you can always visit GamCare, a site that will provide any assistance you need to stop and prevent you from returning to into online gambling. We also want to make sure that we keep children safe from being exposed to even free gambling, and with that in mind, although we write reviews we will not host free play slots on our site.


Do Casinos Rig their slots?

No - online casinos have very little impact on how their slots actually perform. The slot provider sets the RTP value and controls the backend and results of the slots you use. The casino doesn't get to dictate what the winnings for individual slots look like. On the other hand, some casinos do offer their own proprietary games (i.e. they develop them in-house and don't licence them from Netent, Microgaming etc.). In this case, the operator will set the RTP value and control the backend, but their regulated status should mean that the results cannot be rigged.

Can you find cheats or hacks for slots online?

No - all online slots are completely random and should be treated as an enjoyable experience, not as a game used for skill. All online slots use random number generated outcomes, and their is an extremely detailed and advanced algorithm that sits behind them. This means that there is no way to cheat an online slot.

Where Can I Play Online Slots?

There are a large number of online casinos in the UK where you can play slots online. We prefer not to have the game available on our website because we would like to operate as a site that allows people to decide if they want to interact with a game at an approved casino. Without proper age verification anyone can access free play games and we don’t want to make online slot games readily available to those under the age of 18. If you would like to choose an online slot, we hand pick those that we trust to carry out the right age verification protocol, pay users quickly and have affordable and high quality bonus deals.

Where Can I find the Latest Slots?

If you are looking for the latest slots then look no further than here. We update our slot database daily, so you will find between 3-5 new reviews for recently released online slots. After you have looked through the latest slot review and think you might want to try it, then you can click through to one of the partners we have listed on the side. So take a look at the “Latest Games” tab above and see what you think might be enjoyable.

Which Slots have the Biggest Payouts

This is quite a broad question, but we do have a list of the slots we have written reviews about with the highest potential payouts available online - you can see that list here - the highest payout slot we have reviewed on site is from “Dead or Alive 2” with a whopping 100,000x possibility.

Are Online Slots Random and Fair?

Yes completely - there is no way for external sources to affect the outcome of online slots - the are all completely random, sometimes you can win big, and sometimes you can lose a lot. Although the RTP for slots is mostly the same, it is worth checking to see if there is one with a slightly higher than average RTP.

Can you play on your phone?

Yes you can - generally speaking most online slots these days are all produced with mobile gaming functionality. Even slots developed 20 years ago have now been updated so that they work on Mobile. There are only a few exceptions: Those that have been developed using flash capability instead of HTML5 (of which there are only a few like “Wonky Wabbits”) will not render properly on iPhones, and they will require flash enabled on other mobile devices.

Are bonus codes exclusive to Slotswise?

We hand pick the best bonuses we think we can find for our users. In some cases these bonus offers will be tailored specifically to us, which means that you won’t be able to find a better offer for that casino on another site.
