If you’re looking for an online casino that does things a little differently, then SlotsMillion Casino could be just the ticket. Established in 2014, it offers a huge range of slots, an innovative bonus package, regular promotions and giveaways and even the chance to play in a Virtual Reality casino. Licensed in the UK and Malta, they are a trusted and reputable provider.

The catalogue of available slot games stretches to over 3,100 slots with many of them specially optimised for mobile play. There are titles from over 70 developers including industry heavy hitters NetEnt, Playtech, Nolimit City, Microgaming and Push Gaming as well as others like ELK Studios, Thunderkick and Yggdrasil.

With fast payouts, superb customer support and a unique Withdrawal Lock feature, first impressions are good. Let’s take a closer look below at what’s on offer in this Slotsmillion review.

Top 5 Facts

Welcome Bonus – 100% up to £20 + 100 Bonus Spins


The Slotsmillion welcome bonus consists of a 100% first deposit bonus up to £20 + 100 bonus spins. Deposit £10 to £20 first to get a 100% match bonus: i.e. deposit £20 to get a £20 bonus.

Once you deposit, you will get 40 bonus spins right away. You will then receive 30 bonus spins after 24 hours and then 48 hours. That’s a total of 100 bonus spins. Each bonus spin is worth 10p each and valid on some NetEnt slots. They include but are not limited to Starburst, Twin Spin, Aloha! Cluster Pays and Blood Suckers 2.

The bonus and bonus spins come with 48x wagering requirements. The bonus is valid for 7 days and the bonus spins are valid for 24 hours. You must also not use e-wallets when making your maiden deposit; a debit card is simple and recommended here.

To claim your welcome offer, follow these simple steps:

1 Sign up for a new account

Existing Customer Offers

Slots Million Casino treats its customers with plenty of offers and promotions. They give away 15,000 extra spins every Tuesday on a popular online slot and have a Happy Hour on Fridays. There’s also a Slunchbreak promotion where you get 20 extra spins for every deposit of £20 or more from Monday to Friday. Let’s take a closer look.

Summer Million promotion

In the Summer Million promotion, SlotsMillion gives away 15,000 extra spins every Tuesday. Running from 4pm to 6pm UK time every Tuesday evening, extra spin gifts are given away to players who have made 2 deposits in the last 30 days.

If you qualify, you need to visit the Summer Million page and open your chest to randomly win between 15 and 200 extra spins on the week’s selected slot game. With over 1 million extra spins given away, they are given out on a first come first served basis, so you need to be quick. The extra spins come with 48x wagering requirements.

Happy Hour promotion

Embrace that Friday feeling with their Happy Hour promotion. Only available to UK players, you can receive a bonus when you use your Slotsmillion login to access your account between 7pm and 11pm UK time. The possible casino bonuses are:

  • 20% up to £20

The Happy Hour Friday bonuses come with wagering requirements as standard. You can get free cash bonuses, deposit bonuses or extra spins bonuses.

Slunchbreak promotion

SlotsMillion Casino celebrates the best part of the time – lunchtimes. To get you through the working week, there are 20 extra spins for every deposit of £20 or more between 11am and 1pm UK time. Only available to UK players, the extra spins are on Pragmatic’s Chilli Heat Megaways slot with winnings coming with 48x wagering requirements.

Slotsmillion Loyalty Program

You won’t find a dedicated loyal program or VIP scheme on the SlotsMillion Casino website. The customer support team do offer loyalty bonuses to their players, though. As soon as you can benefit from a loyalty bonus, you will be contacted directly by email or text message. The offers include reload bonuses, extra cash bonuses and extra spins.

Site + Mobile


The SlotsMillion Casino site is very clearly laid out and is 1 of the best I’ve come across. With tabs dedicated to promotions, virtual reality, banking, Summer Million, responsible gaming and about us, it’s all about the Games lobby.

You will see sections dedicated to Classic Slots, New Slots, Video Slots, 3D Slots and Jackpot Slots. Most games can be found within the Video Slots section. Then you have Software that displays all the slot providers – like NetEnt, Play ‘n GO etc.

You’ll also find slots categorised by Theme (animals, mythology, movie and TV etc) and you can search by feature too by selecting this option from the navigation menu. If you have a special liking for Megaways slots, then just tick that box and you’ll be offered a selection of all the Megaways slots available.

If you use your SlotsMillion login to access your account, you can also choose favourites to put in a dedicated section, last played slots and My Extra Spins. The latter section shows you slots on which you have free spins available.

In summary, not many online casinos offer this much filtering which really helps if you know what you’re looking for. It really makes Slotsmillion Casino stand out from the competition.

Slotsmillion Mobile Casino

There is a Slotsmillion app available on iOS and Android at their respective app stores. Simply search for the brand name and it will appear. What we did notice is that it doesn’t appear at the top for us, so you may need to scroll a little to find it, but it is there.

You can also play SlotsMillion slots via your mobile browser. Just got to their website on your handheld device. Most of their slot games are available on smaller screens which makes it ideal to play on the go.



Where SlotsMillion Casino really comes into its own is in the range of games it offers. There’s a massive catalogue of over 3,100 online slots to choose from. If you like to play on the go, then you’ll be especially well catered for with a huge selection of specially optimised mobile games on offer.

There are titles from more than 60 developers. In fact, it’s easier to list which developers then don’t have than they do. The layout is nice and simple making it a breeze to find your preferred slot game(s). That selection includes but is not limited to:

Play’n GO NetEnt Skywind Big Time Gaming
Playtech Microgaming IGT Quickspin
Pragmatic Play 1x2gaming Ainsworth Bally
Barcrest Core Gaming ELK Fantasma
Gamevy Iron Dog Just for the Win Leander
Lightning Box NextGen Gaming Nolimit City Pear Fiction
Push Gaming Rabcat Realistic Red Tiger
