New Slot Reviews

We enjoy reviewing slots for The team here have been playing slots since they were available online (that's over 20 years ago and back then our go-to casino was often Captain Cooks Casino!) However, keeping up with the number of new slots coming into the market is often a difficult task. This is because there are now over 100 slot game companies to watch that consistently deliver brilliant new slots every single month. Most software developers produce at least 1-2 new slots per month, although many leading developers like Netent, Play 'N Go, Big Time Gaming and Elk Studios tend to surpass that number very easily. Furthermore (and something really good to see) is that it has also become a trend for established developers to 'partner up' with smaller independent studios. This not allows the smaller studios to reach a broader audience but also the larger studios to release games that are truly unique and innovative and different to what they usually do.

We get around this "there are too many new slots to play" occupational dilemma by picking the best new online slots and forgetting about those that aren't up to the task. As a team, we check what new slots are coming up in the calendar and then often have a good 'once over' look at them because that's all it takes. By now, we know we can spot a good slot from a disappointment. What's more, because we're utterly spoiled for choice with new slots, we tend to skip games that are mere "recycled" versions of earlier games and ones which aren't ground breaking enough for 2021. Because, at the end of the day, we're searching for the best games online because we want to make it easy for you to find the newest slots at the best casino sites. 

How We Review New Slots

The review team at has been reviewing slots since 2003. Not just for this website, but for many other leading gambling review websites and publications. Our team has been involved with the iGaming industry for over 2 decades, giving them a great foundation of knowing online slots, casinos and gambling sites - inside and out. We know exactly how the mathematics and mechanics behind slot games work and we have a keen attention to detail in our reviews. Our online slot reviews aim to offer an informative, accurate and impartial guide to each game. Our reviews will help you make an informed decision as to whether you want to play the slot or not. Here's a checklist of what we're looking at when we review new slots:

  • Slot Introduction: We set the review up with a bit of information about the game: what to expect in terms of theme and audio and any interesting facts we uncover that we think you may like and enjoy reading about.
  • Slot Details: Those important details like paylines, stakes range, slot variance, RTP %, maximum win potential and jackpots go here. It's important to understand how a slot works and how it's designed to play out, so we try to cover as much ground here.
  • Game Features: What features will you encounter when playing the game? We try to give a good overview and synopsis of each feature (such as free spins, pick and click features) and how they can help you win.
  • Accessibility: How mobile/tablet friendly is the game? Does it play out well on the smaller screen?
  • Review Summary: A round-up of our experience playing the game for real money and also some footnotes to help you decide whether the game is worth playing or not. We also try to compare to other slots that are similar too.
  • Best Slot Sites To Play The Game At: We then list the top slot sites that have the game in their portfolios. Casinos in this list will not only have the game to play but offer new customers a fair and high-value welcome bonus and if possible, free spins package.

Why Play New Slots?

Most of us have our "go-to" slots that we play regularly. They could be games you win on the most or those you feel lucky on or those you just enjoy playing because it boasts entertaining in-game features. But playing brand new online slots is highly recommended as you might discover your new favourite slot packed full of features that you have never encountered before. There are so many slot providers out there; the competition for players to play their new games is fervent. Naturally, this leads to games developers, continually searching for novel innovations, concepts, and bonus features to attract and wow players over and over! This is why people searching for new slots has grown tenfold over the past couple of years.

How To Choose A New Slot Game

When exploring new slot games to play, there are a few basic elements you may want to check out first. Making sure that these are crossed off your list will lead to an overall better gambling experience and, for those slightly worried about trying something new where the real money is involved. Here are the essentials to look for in any new slot game that may take away any worries you might have:

1. Check the Games Bonus Features

New slots often boast a wide range of bonus features to appeal to more players. We recommend looking for the most exciting in-game features, or features that appeal to you the most. Many people look for slots with free spins features, others like pick and click features or progressive jackpots to get the most from playing online slots. What's more, don't overlook some newer slot features which level up your gameplay, such as expanding reels, avalanche reels, colossal reels and the trending Megaways feature. If there was ever a feature that adds a certain drama to gameplay, it'll be a toss-up between Megaways and a pick and click feature!

2. Look at Themes That You Fancy

There’s a whole world of themes to pick from when it comes to slots. From Ancient Egypt, Halloween, Christmas, Ancient Greek to the Mayan Jungle, the list is endless. A good theme should attract you into the game, not deflect you from your play.

3. What are the Slots Max./Min. Bets?

Knowing a games minimum and maximum bets is pretty crucial because it will determine compatibility to suit your bankroll and budget. Most online slots range from 10p and 20p up to £100 and £200 per spin (and sometimes more). Always check the game's minimum and maximum bet levels so you can set your budget accordingly.

4. Do You Want A Slot With A Hefty Jackpot?

Many slots players love to play progressive jackpot slots. There are tons available, often with local and progressive jackpots. Newer progressive slots include daily "must fall" jackpots which are prizes guaranteed to drop every 24 hours. If you enjoy slots with jackpots, then you'll need to find the right games and also check their jackpot amounts to time it right. There's no real way of knowing when a jackpot will drop, but checking a game's jackpot before you start will help. For example, if you play Mega Moolah and the jackpot has just been won, the chances are it won't be won again any time soon because large progressive jackpots need time to build up their prize pools again. Choose a jackpot slot that hasn't been won for some time - and of course the slot with the biggest jackpot.

5. Look at RTP %'s (Return To Play Percentages) 

This is what you want to be looking at too: a slots RTP %. A Return to Player (RTP) is a convenient percentage indicator that shows the average amount won back by players over a prolonged period. The higher the RTP % is, the bigger the chance you have of winning some funds back. Some slots have a fixed RTP % but some slots increase in % the more you play them. All licensed UK slot sites publish their game RTP's on their website (usually in the footer) so it's easy to find the best-paying games. We've gone one step further and listed the highest RTP % slots here

6. Check Volatility / Variance

Many people don't check other important facts about a slot before they start, and one such thing is a games variance/volatility. It's always a good idea to take the variance and volatility of a game into account when looking for new slots to play. The higher the volatility, the bigger the payouts will but, and here's the twist -the wins will come less frequently. On the flip side of that, a low volatility game will pay out a lot more and more often, but the prizes will be smaller. All our slot reviews list the variance of each game to help you pick out a compatible type of game.

7. Mobile Slots Checklist

Most new slot games are compatible with all mobile devices, except for some older games. It's important to be able to play as and when you want to, which is why many game developers put a lot of effort into making their mobile slots the best. New slots have no excuse - they need to be compatible or they won't stand the test of time.

As mentioned, there are over 100 different casino game providers each furnishing us with plenty of popular, classic, and of course - a barrage of new slots to try out! The number of slot providers is huge and they are each competing to provide the best new slots on the market. As a result, online casinos can offer more than 1,500 slots from these providers. Below, we've added the most popular slot providers that you're likely to encounter at new slot sites. We've given you a little snippet on each of them so you can discover a little bit more about these companies, where they're based and what makes them tick.


Netent is the pioneer of new online slots. Often regarded as the best casino games developer in the world, Netent has been leading the market for over 2 decades. Netent launches new slots every month, often showcasing collaborations with Hollywood and well-known brands to bring you high quality branded slot games. Netent also does a great job of creating new slot game features, such as colossal reels, mini slot machine features, stacked wilds, mystery reels and free spins.


Microgaming is one of the oldest online slots developers and is probably one of the most successful too. Microgaming started in 1994, and has since then, created hundreds of Microgaming slots that are adored by slots players around the world. Microgaming is also a trusted casino game brand among many online casino operators. Microgaming launches new slots every month to acclaim and also operates the Mega Moolah jackpot slots too - a progressive jackpot that's featured in the Guinness Book of Record for paying our the single biggest jackpot win online (twice over). Other popular Microgaming slots include Thunderstruck II, Game of Thrones, Immortal Romance, Lara Croft: Temples and Tombs, Sisters of Oz Jackpots, Blazing Diamonds Wowpot, Jurassic Park, Temple of Medusa and Divine Diamonds.

Play 'N Go

Play ‘N GO is a Swedish founded company with headquarters in Stockholm and Malta. Play 'N Go was one of the first game producers to get mobile slots completely right from the get-go. Over the last decade, Play 'N Go has grown to be one of the most appreciated and popular slot developers in the gaming industry. Play 'N Go consistently deliver amazing new slots as well as having successfully found a way for casinos to use their innovative "back office" to help make players user experiences more interactive and engaging.

Elk Studios

Swedish-based company ELK Studios was late to the party, only establishing in 2013, however, since then, they have successfully managed to carve out quite a name for themselves. Their ethos has always been to focus on a small collection of high-quality slots, rather than churning out loads of poor slot games. Some high-profile Play 'N Go Slots include Bompers, Ivanhoe, Electric Sam, Taco Brothers, DJ Wild and Ho Ho Tower.


Thunderkick has been creating unique and individual slot games since 2021. Thunderkick Games is based in Stockholm but has offices in the iGaming Mecca of Malta. The production quality across this library is extremely high, and like Elk Studios, Thunderkick prefers to have a "quality of quantity" approach. Furthermore, Thunderkick slots are well known for offering higher than average RTP % than its peers, which is a factor to consider when looking for new slots online. Notable Thunderkick slots include Esqueleto Explosivo (highly recommended), Toki Time, Flux, Frog Grog, The Rift, Spectra, Turning Totems, Luchadora and Pink Elephants. Whilst new slots aren't released every month from this vendor, we can't blame them as the quality of their slots is extremely high.


Playtech is one of the largest online gaming software companies in the world. Playtech began building its impressive portfolio back in 1999 (around the same time as Microgaming) and besides its numerous other popular casino table games and live dealer game studios, Playtech boasts more than two hundred online slots. Notable slots include Ugga Bugga, Sweet Party, The Flintstones, Dr Love More, Jackpot Giant (Progressive Jackpot) Hot As Hades, Beachlife, Gladiator, Cowboys and Aliens, Baywatch, American Dad, A Night Out and Ace Ventura. Playtech doesn't launch new slots as regularly as some, but what they do turn out usually is high quality, has a large payout and often is a branded game well worth waiting for.

IGT Slots

IGT slots are casino games made by International Gaming Technology (IGT), which is owned by gaming giant Scientific Games Corporation (SGI). Slots made by IGT are generally the most popular slots in Las Vegas casinos, as well as Reno and Atlantic City. However, their most popular online slots tend to be Cleopatra Slot (which is the most popular IGT slot in the UK) Wheel of Fortune on Tour (which is a top slot with a very high RTP %), Pixies of the Forest, Siberian Storm, Golden Goddess, Da Vinci Diamonds, Wolf Run and Black Widow. New slots are released regularly, with most reputable slot sites wanting to offer them as soon as they can get their hands on them.


Founded over ten years ago in Stockholm, Sweden, NoLimit City has recruited a highly skilled workforce who are committed to the gaming industry and its players. No Limit City wanted to take the industry to the next level by offering casino operators and their punters an unrivalled experience - and that's exactly what they're doing. Premium new online slots are launched every month, with a superfluous design and cutting edge features. Furthermore, Nolimit City ensures that its payout percentages are always above average too. You'll find that most of their games have RTPs of 96% or more, with the highest being Kitchen Drama Sushi Mania (96.77%) and Tesla Jolt (96.61%). Popular new slots include Fire in The Hole, Tombstone, Hot 4 Cash, Manhattan Wild, Pixies Vs Pirates and East Coast Vs. West Coast.
