Secret Slots is one of the most renowned UK online casino sites. The site was launched back in 2014, but with the rebranding in 2017 it looks quite fresh and modern. The team behind the site have plenty of experience and are in charge of a number of successful and popular online casino and bingo sites.

Secret slots has a remote gaming license from the UK Gambling Commission and the Government of Gibraltar.

Secret Slots has a somewhat basic website. It’s very much focused on slot games with some scratch cards available too. The site itself holds over 500 slots, this is also the message on the homepage banner. It then displays some recommended slot games before presenting more slot categories.

The signup process was nice and easy. It was broken down into four-steps with all the basic information required as well as an occupation. Once I completed the sign-up, I was taken to a landing page that promoted the welcome offer. I decided against claiming the welcome offer this time.

The site's layout maintains simplicity with all menus in view, making it easy to journey around the site. I did find that at times the site load times were lacking. It almost felt like this website was built for mobile devices before a desktop computer.

Overall rating:


Secret Slots features two alternative welcome bonuses for new depositing UK players. Both bonuses have their own unique bonus codes:

  • Exclusive bonus on Bojoko: Deposit £5, get 150% bonus + 15 Free Spins. Bonus code: HOT.
  • Deposit £5, get up to £15 Bonus + 15 Free Spins Bonus code: HOT

Here's how it works:

  1. Sign up and verify your account
  2. Use the bonus code
  3. Make a qualifying deposit
  4. Enjoy your bonus

As a new player, I had the option to claim a first deposit offer of 25 Free Spins when I deposit £10 or more. This is a very simple and straightforward welcome offer that would appeal to any casino player.

However, the maximum win cap on this welcome offer is a mere £2.50 and that is credited as a bonus with a whopping 40X wagering requirement attached. In other words, the bonus win is not being cashed out.

I would have liked to see little to no wagering requirements on a bonus this small. I’ve not come across a welcome offer that’s been so heavily protected by terms and conditions, despite only being worth £2.50.

First deposit bonus code

Secret Slots's first deposit bonus code is HOT.

Significant terms and conditions

  • New UK players only. 18+
  • Min Deposit is £5
  • 150% Bonus up to £15 Slot Bonus + 15 Free Spins
  • Use bonus code: HOT
  • Deposit balance is withdrawable at any time
  • No Max Cash Withdrawal limit

Full terms and bonus terms apply.

Extra and no deposit spins

There are two different free spin packages for new players. Depending on how much you want to deposit, you can either grab:

  • 15 Free spins with £5 deposit, or
  • 25 free spins with a £10 deposit

Free Spins expire after 7 days.

VIP / Special promotions

The first deposit offer is just the beginning, players can benefit from a range of other offers. There are two loyalty exclusive offers. The first includes up to 50 extra spins awarded daily, again with no wagering requirements, whereas the Daily Classic offer gives you a chance to win spins, cash prizes, as well as other bonuses.

Plenty of more surprises await at Secret Slots if you manage to become a VIP member, including a plethora of premium bonuses and various tailor-made offers.

Once you visit the site you’ll realise that this is the place to be if you’re looking to play top online slots. If you are unsure which game to play, you can always check which games have been hot – i.e. where there have been a lot of pay-outs.

There are more than 500 slots, and while it is not easy to single out just a few of them, these are some of the most renowned titles:

  • Fluffy Favourites
  • Wild Wild West
  • Stampede
  • Cash Stax
  • Guns ‘N’ Roses
  • Cleopatra
  • Rainbow Riches Reels of Gold

All games that are available at Secret Slots have been tested by eCOGRA, the world’s leading online casino software testing agency and their certificate ensures that all provided games are fair and random.

Secret Slots splits their games up by ‘Hot Games’, new, scratch and slots. There is also a search bar to find specific slots. I would have liked to see a jackpots section since I know they host a few jackpot games. Some slots have a ‘Recommended’ banner on them and are heavily promoted on the page. You can hit a heart icon which will list the games in your favourites section which I liked.

With over 500 slots to pick from, I had plenty of choices. They host games from some of the industry’s best slot providers, so there are some great titles to pick from. After a short browse, I had a spin on the Wish Upon a Jackpot slot and Bonanza which were one of the recommended games. Unfortunately, I did not hit any significant wins. The gameplay was good but seemed more appropriate on mobile with a touch icon rather than a button CTA to spin the reels.

I was pleasantly surprised to see how well-presented the mobile site was. It certainly felt more natural playing on the mobile site rather than the desktop site. It maintains a simple display with all slots within easy reach. There are not many menu options which made it nice and easy when playing on mobile. It wasn’t cluttered or too in your face either.

The presentation of the games makes it easy to scroll through and select a game that piques your interest. I found that they host a big number of mobile-friendly slots. I wouldn’t be surprised if all their games were mobile-friendly as it seemed to be a mobile-first casino in my eyes.

The gameplay on my iPhone was also excellent. I didn’t experience any lag and it was immersive and fun. I preferred the mobile experience on Secret Slots, although there is no dedicated mobile app at this time.

I had an issue with depositing so I had a legitimate reason to reach out to the Secret Slot support team. The only support option I could see was a Help chat button on every page. I looked for a dedicated contact page but I couldn’t locate one – there wasn’t even a footer menu on the site.

Once I had opened the live chat option I noticed how outdated the chat feature was. It felt like I was back on Windows 95. Ignoring the aesthetics of the chat feature, I was able to get on chat straight away to a customer service representative. Although I had to wait about ten minutes for them to find a solution to my problem, I did manage to resolve my issue.

After exploring the site some more I found that they do have a phone number and email address for support issues. I found these hidden within the document upload page.

It was effortless to upload my documents and have my account verified. The documents section was with my account page. There are instructions on the file type that should be uploaded but no mention of what documents should be uploaded. I went ahead and uploaded a copy of my passport which was enough to get my account verified.

The minimum amount that you can deposit to your Secret Slots account is £10 and there are several available banking options, including credit and debit cards and e-Wallets, but it is also possible to make a deposit by phone.

I experienced quite a few issues when trying to make my first deposit. First, the deposit page would not load. I was getting a ‘Session has expired’ error message. After a few attempts, I contacted support who suggested I try another browser. It worked on Google Chrome but not on Safari.

Once I opened the deposit page I noticed I could not see some of the field titles, nor the CTA to complete the deposit. It looked like the deposit page was built for mobile. I plugged in a larger screen so I could see the fields and complete my deposit. With all the delays involved, this is the hardest experience I’ve had trying to deposit to an online casino.

The one thing I did like about it was that it has a tick box option to tick if I wanted to claim a bonus.
