Casino Bonuses and Promotions

Now that you know a little bit more about what kind of casino Slot Boss is, let’s take a look at one of the most important aspects of an online casino - their bonuses and promotions. After all, one of the benefits of playing at an online casino is the rewards you get for signing up and being a loyal customer! 
The only promotion available at Slot Boss is their welcome bonus. New players can receive a matched deposit bonus up to the value of £150, plus 50 free spins on the popular Big Bass Splash slot when they sign up and make a deposit. This bonus is available to all new users, and all you have to do to claim it is create an account and make a deposit of over £10. 
While the welcome bonus is a generous one, there aren’t any other bonuses or promotions available at Slot Boss. The closest they come is a £10 million Gigantic Jackpots promotion, where players can opt-in and play any of the slots with a Gigantic Jackpot badge for their chance to win huge prizes. However, we expect casinos to offer more in terms of deposit bonuses and free spins to their existing players, so we hope to see more from them in the future. 

Loyalty Programs 

Unfortunately, Slot Boss does not offer a loyalty program to its users at this time. However, the Promotions page is regularly updated, so check back regularly to ensure that you’re getting the best promotions from Slot Boss Casino. 

Tips & Recommendations 

If you want to maximise the online casino bonuses available at Slot Boss Casino, make sure you follow these helpful tips. 

  • Use The Full Bonus - Slot Boss Casino is offering players a matched deposit bonus up to the value of £150, but the minimum required deposit is only £10. If you want to make the most of your welcome bonus, make sure you deposit the full £150 to receive £150 in bonus funds. 
  • Plan Your Bonus - The expiry date for your bonus funds is only 7 days from when you receive them, and any bonus funds that have not met the wagering requirements within that time will expire. So, make sure you leave yourself plenty of time to play before claiming your bonus. 
  • Check The Ts&Cs - The terms and conditions will outline the wagering requirements you need to meet to be able to withdraw your bonus funds. They also outline other rules associated with the bonus, so always read them before signing up and claiming the bonus. 

SlotBoss Registration & Banking

Now, we’re sure that you’re eager to claim the welcome bonus at Slot Boss Casino, but before you do, you need to create an account and make your first deposit! Let’s take a look at how you do just that.  

Create an Account 

Creating an account at Slot Boss Casino is easy to do, thanks to the simplified sign-up process. All you have to do is fill in a couple of forms, and you’ll be set up with your very own Slot Boss account.

After creating your account, you’ll need to fund it if you want to claim the generous welcome offer. While the number of payment options available at Slot Boss is rather limited, they include the most popular payment methods, so you should have no issues making a deposit. 
One of the major selling points of Slot Boss Casino is that there are no minimum withdrawal limits, so no matter how much you have in your account, you can withdraw it.

Tips & Recommendations

To make sure you have a smooth sign-up and depositing experience, follow these helpful tips. 

  • Use Real Info When Signing Up - It’s important that you use your real information when signing up for SlotBoss Casino. If you create your account using false information, the casino will close your account, and any funds in that account may be seized. 
  • Withdraw With PayPal - PayPal offers by far the quickest withdrawals of any of the payment methods available at Slot Boss Casino. Therefore, if you want to get your money as soon as possible, we’d recommend always withdrawing with PayPal. 
  • Try Games For Free - Many online casinos allow players to try their games for free without having to make a deposit. You won’t be able to win real money, but you’ll be able to get an understanding of how the games work without any risk.  

Slot Boss Games

Now that you’ve gone through the boring part of opening your account and making your first deposit, it’s time to start having some fun! Slot Boss has thousands of casino games to enjoy, and despite what you may think from the name, they offer more than just slots. They have a great selection of live casino games and table games on offer, so let’s take a closer look at the games you can enjoy at Slot Boss Casino. 

Online Casino Games 

While the site may be called “Slot Boss,” they offer much more than just online slots. They have a number of high-quality casino games to enjoy, so no matter what you enjoy playing, you’ll find your game at Slot Boss Casino. 

  • Online Slots - You’d expect that a site named “Slot Boss” would have a number of quality slot games - and that’s exactly what you get here. There are over 600 online slot games to play, including popular titles such as Fishin’ Frenzy, Starburst, and Cleopatra.
  • Live Casino Games - If you’re a fan of table games, you’ll be thrilled with the number of live casino options available at Slot Boss. They offer a range of games, from classic games such as online blackjack and online roulette, as well as modern game shows such as Extra Chili Epic Spins and Crazy Time Live.
  • Table Games - If you prefer playing table games at your own pace, you’ll want to check out the range of animated games available at Slot Boss. They have all of the classic games you’d expect to see, as well as some modern games such as Football Studio and Mega Ball. 

Playing for Fun or Real Money 

One of the things you must decide after signing up for an online casino is whether you’re going to play for fun or for real money. Almost all online casinos offer play money options, but many players choose to play for real money instead. If you’re not sure which one’s right for you, take a look at the explanations below. 

Playing for fun means that you’re only playing for the enjoyment of the game. There’s no chance to win real money playing these games, so no matter how many hands of blackjack you win or jackpots you hit, you won’t become any richer. However, there is no risk of losing real money when playing these games, which makes them perfect for beginners. We recommend playing for fun until you fully understand how the game works, then start playing for real money when you’re more comfortable. 

On the other hand, playing for real money means that every hand you play or spin you make affects you financially. Either you win, and you win real money, or you lose, and you lose real money. Playing these games comes with the real risk of losing money, and we at MansionCasino always encourage our readers to gamble responsibly. 

Software Providers 

Many savvy casino players know the importance of having a large selection of games, but we think it’s just as important for an online casino to offer games from a large selection of software providers. The more software providers a site has, the better the choice is for the player. 

Boss Slots offers games from over 20 of the best software providers in the industry, including NetEnt, Evolution, and iSoftBet. These companies are known for creating some of the best casino games on the market, and it's a testament to Slot Boss that the site can attract so many big-name software providers. No matter what game you play at Slot Boss Casino, you can be sure that it’s come from a top-quality software provider. 

Slot Boss Mobile App

If you’re a fan of gambling on the go, you’ll be pleased to hear that there are two ways of enjoying the games at Slot Boss, no matter where you are in the world. You can download the dedicated Slot Boss app from the Google Play Store or the Apple App Store, or you can play from your mobile device’s web browser. 

However, we’d recommend only playing from the mobile app, as that’s where most of the effort has gone. The casino app looks great and has been well-optimised for the smaller screen. All the text is readable, none of the images look distorted, and the app itself is really easy to navigate. It doesn’t take long to find your favourite game, and with just a couple of taps, you can start playing. 

On the other hand, the mobile site is not well-optimised at all. The text overlaps the images, some of the images spill out across the page, and overall it just looks very unpolished. Thankfully, the mobile app more than makes up for the lack of quality from the mobile site.

Slots Boss Safety, Security, Licensing, and Regulations

We at MansionCasino take security extremely seriously, and it is always our number one priority when creating these casino reviews. We will never recommend a site that is unsafe, and our team of experts thoroughly checks the security and licensing credentials of each site we review. Let’s take a closer look at what they found when they looked into Slot Boss Casino. 

  • Security - To ensure that your data and funds remain secure on its site, Slot Boss uses secure encryption technology for every connection to the site. You can check this yourself by seeing if the site address starts with HTTPS://, or if there is a padlock icon next to the web address. This secure connection means that only Slot Boss can see the data you send, which ensures that no hackers or malicious third parties can access it. 
  • Safety - Slot Boss is committed to player safety, offering a number of tools to help you stay in control of your gambling. These tools include deposit limits, wagering limits, reality checks, and much more. They even include links to a number of companies that can help people who are suffering from problem gambling. 
  • Licensing - Slot Boss Casino is fully licensed by the UK Gambling Commission. The UKGC is one of the most respected gambling authorities in the world, and the requirements to receive a license from it are some of the toughest you’ll come across. This means that you can be sure that Slot Boss is a safe and secure place to play. 


One of the reasons why it’s so important for an online casino to have a license from a recognised gambling authority is that it shows they’ve been audited by an independent company. These companies are staffed with casino experts who check the security, safety, and fairness of the casino to ensure it’s a safe place to play. As long as the site can meet the standards of the auditors, it will be given a licence. 

When a site receives a licence, they have to continue to show that they meet the required standards, and any casino that doesn’t meet the requirements will have its licence revoked. This means that any site with a license from a recognised gambling authority, such as the UKGC, can automatically be assumed a safe place to play.  

SlotBoss Customer Support 

Another important aspect of an online casino is its support system. After all, if something goes wrong while you’re playing one of their casino games or trying to make a deposit, you need to know that someone will be there to help. Slots Boss has two methods of contacting the customer support team, as well as an FAQ section that will answer many of the common questions you may have. 

The best way to get assistance is to speak to the live chat team. This team is available 24/7, and you can often be connected to a representative in just a couple of minutes. We found them to be extremely helpful whenever we had a query, with almost all of our questions or problems being resolved then and there. 

You can also send an email to the customer support team, but we’d only recommend choosing this option if your query isn’t urgent or if you need to submit documentation. The email team is also available 24/7, but it often takes a few hours to hear back from them after sending your email.

By far, the biggest draw of Slot Boss is its range of online casino games. With thousands of Boss slots at your fingertips, as well as a healthy range of live casino games and classic table games, you’ll never get bored playing at this site. As well as a great range of games, it also has a fantastic mobile app, a solid range of banking options, and great customer support. While the bonuses and promotions are a little lacking, we think this is a site that’s well worth checking out, so why not try it out for yourself?
