Slots Heaven was founded in 2013 by Gibraltar-based Onisac Casinos Ltd. – the team behind and part of the Mansion Group. With a name like Slots Heaven, you’d expect this casino to be packed with slots titles, and that’s exactly what you’ll find once you sign up for an account. As winners of Online Casino Operator of the Year 2018 at the International Gaming Awards, the Mansion Group have a track record spanning more than 10 years. But how does Slots Heaven fare against the top notch competition on the UK casino scene. Read our detailed Slotsheaven review to find out

Safety and Trustworthiness

The award winning Mansion Group was founded in 2003, serving its customers through a number of different online casino and sports betting brands. Football fans among us will instantly recognize the Mansionbet name, as one of the chief sponsors of Spurs, Crystal Palace and AFC Bournemouth – but that’s just a small part of what makes Slots Heaven a trusted, secure place to play.

Slots Heaven is licensed and regulated by the UK Gambling Commission to operate within the UK . In addition to its UKGC license it also holds a license by the Gibraltar Gaming Authority, providing a double layer of coverage. Reputation counts for a lot, and the Mansion group come with a good track record, but it’s always a good idea to confirm that a casino is operating under the watchful eyes of independent regulators, as is the case with this casino.

Slotsheaven guarantees security via a firewall and RSA 128-bit encryption technology whilst data rights and privacy are confirmed by adoption of the GDPR and its own privacy policy. Payments are processed via industry leading  payment gateways, adding their own layers of encryption and security technology. Between Slots Heaven’s own measures, and the security technology of best-in-class payment processors, it’s hard to see how their site could be any more secure.

Feedback on player forums can best be described as mixed. Most players reported positive experiences with regards to the overall playing experience and RTP, with negative comments reserved for the time taken for withdrawals and follow up customer support on this issue. This does seem to be a problem for all the brands across the Mansion group including, Mansion Casino and Mansionbet. Its not that you wont’ get your money back, rather the times expressed on their website don’t match the reality. Another issue, and one common to many Playtech licensees is the low max daily withdrawal of £10,00


Deposits & Withdrawals

Slots Heaven supports all the usual payment methods, on both the deposit and the withdrawal side – including PayPal, which is great for convenience. Pending time (i.e the time before the casino actually starts to process the payment) is up to 72 hours, which is high. Thereafter, payments according to the Slotsheaven website are made in a time frame of 1-2 days (Neteller) to 6-8 days (Credit Cards).



Slots Heaven welcome new players with a 100% deposit match up to £100, plus 200 free spins. Players qualify for the welcome bonus from a deposit of as little as £20, and subject to the terms and conditions, this can be a great start to your new account.

The wagering requirements on the deposit match stand at 40x, and players must meet this requirement before they are eligible to withdraw from the bonus. This might seem high, but it’s now around the standard for offers of this kind. A betting limit for slots of a maximum £5 per spin, and 10% of the bonus amount maximum for all other games, can make this more challenging to clear profitably.

The bonus spins are awarded in increments, with 40 free spins coming from deposit. The remainder come in lots of 20, allocated each day for 8 days, until the full allowance of 200 spins has been credited. The spins are only eligible for Age of the Gods, and any winnings from these spins are credited as bonus cash. Again, this bonus cash must be wagered 20x before you are eligible to withdraw.

Both parts of this bonus offer are open to new players only, and it goes without saying that you must be 18+ in order to play here, let alone claim the bonus. Wagering contribution rules also apply, but if you stick to slots and scratch cards, you’re contributing at 100%. Roulette and casino hold’em contribute at 25%, and most other games 20%. You can find full details of the contribution requirements, and all other relevant restrictions by consulting the terms and conditions of the bonus offer – always recommended before you sign up.

As bonus offers go, this seems fair. It’s not the easiest bonus in the world to clear with the 40x wagering, but the free spins make up for that at only 20x winnings. The £100 maximum is a nice limit to get started, although some casinos do offer more. It would be nice if the spins were a little more flexible, particularly as most new players want to try several different games, but it’s a still a fair bonus, and a decent enough welcome to playing at Slots Heaven.

Game Selection

Slots Heaven declares themselves to be ‘the divine home of slots’ – a bold claim for any online casino, given the quality of the competition. True, they have a decent range of slots games available, with both regular and jackpot slots, offering prizes running into the millions. But for the time being, Slots Heaven only supports games from one developer, which limits the total number and range of slots games somewhat.

Slots Heaven is a Playtech casino, and you’ll find exclusively Playtech slots here. Playtech is a reliable partner and overall the games overall are of an ok quality, fast to load, and fun to play. It’s just that the Slots Heaven offering feels a little limited and somewhat tired, when casinos are combining games from multiple different software providers. As a comparison Slotsheaven offer just over 210 slots, whereas Videoslots which offers games from over 20 different companies has 1000+. As the self-proclaimed ‘the divine home of slots’, you’d expect a little more, and this is something Slots Heaven could look to develop in future. Stand out slots include: Age of the Gods, The Dark Knight, The Matrix and Plenty O’ Fortune offering a varied and engaging selection for avid slots fans.

Despite the name, Slots Heaven isn’t just a slots sites – this is a fully fledged online casino, with other classic casino games at your fingertips. There’s a good selection of table games here too, which go a little more in-depth than you’d find in some other online casinos. Aside from multiple variations of classics like roulette and blackjack, you’ll also find Sic Bo, Red Dog, Pai Gow Poker, and more. There’s even a dedicated video poker section, with some 15 titles to choose from.

There’s also a live casino here, where you can enjoy high quality streaming action in real-time. Choose from blackjack, roulette, baccarat, and casino hold’em, with a few variants of each of the games to keep you busy. Again though, the live games provider is Playtech whose live game streaming and table features does lag a little in comparison to Evolution Gaming.

Mobile App

Slots Heaven has mobile apps for both iOS and Android devices. The apps are well designed, allowing for easy navigation on any compatible device. The apps are free to download of course, and you can find direct download instructions for the Android app from the apps link on the Slots Heaven website. While the selection of games available is slimmer on mobile, it should enough for most players.

There’s also the option of playing in-browser, thanks to the native website for mobile. This renders perfectly on any smart device due to its responsive design, so you can enjoy the same caliber of experience whenever and however you choose to play.

It’s not just new customers that get the best of the bonuses – loyal players are rewarded, too. There aren’t tons of different promotions, but these are updated on a regular basis, and you can find out details for the latest offers under the Promotions tab from the main menu. Aside from the welcome package, you’ll find offers like Spin Special, which offers you 10 free spins for every £10 deposits during the set hours of 7-9pm each and every day. Or there’s Monthly Madness, where you can pick up 100 spins each month for White King, subject to terms and conditions, as always.

You’ll also find exclusive offers for VIPs, and players become VIPs by collecting loyalty points. This can earn you higher withdrawal limits, faster payments, personal bonuses and cash back deals, as well as certain other perks, depending on your loyalty level. It’s all part of rewarding players who make Slots Heaven their go-to site for playing slots and other casino games online.


Slotsheaven offers 24/7 support by phone, no live chat.. As mentioned though support does seem to be the achilles heel of the Mansion group.

Review Summary

As part of the Mansion Group, Slots Heaven already comes from a recognized operator albeit one with reported issues on withdrawal times. Still, overall Slots Heaven can still be classed as a reputable, trustworthy and secure place to play, and you can deposit and withdraw in confidence through the variety of supported payment methods.

The welcome bonus won’t blow your mind, but it’s a fair enough offer nonetheless, made better by the free spins. Its also backed up by ongoing promotions and a loyalty programme, which makes it worth your while to stick around.

Despite the casino’s mission to become the rightful home of online slots, one area where this is lacking is in the slots department. There are plenty of high quality games, including some incredible jackpot titles – it’s just that the lack of multiple different software providers limits your options. And a total slots number of 178 is frankly, quite poor compared to some of the newer breed of casinos like Casumo, Dunder etc

Weighing everything up, it’s fair to award Slots Heaven a 7 out of 10. What’s there in terms of games and bonuses is fine – with just a few more slots developers added to the collection, this is a site that could easily be in contention for an 8 out of 10.
