Promotions And Bonuses

Welcome Bonus

Like most other online casinos, Slot Boss Casino is offering new customers a welcome bonus as a reward for registering and depositing into their casino account. Users can claim a 100% deposit bonus of up to £50 with a minimum £10 deposit. According to the terms and conditions, you must wager the bonus 40x before anything can be withdrawn within 30 days. In addition, users who claim the bonus can only wager a maximum of £5 until the wagering has been completed.

£10 Free

In addition to the above welcome bonus, the casino also rewards new customers a Slot Boss £10 free no deposit bonus for registering and successfully adding a credit or debit card. According to the terms and conditions, however, the Slot Boss £10 free bonus must be wagered 99x before it can be withdrawn and you can only wager £5 at a time when clearing the wagering requirements. Lastly, the cash bonus expires after seven days and has a £50 withdrawal limit which means winnings over this amount will be lost.

Promo Code

Although many modern casinos now require you to enter a promo code to successfully claim a bonus or promotion, Slot Boss does not. This is because all bonuses at the casino are automatically credited to your account, which means you’re not required to enter a Slot Boss promo code.

Other Promotions

Slot Boss also runs other promotions, allowing you to win five free spins on Reel King Mega by depositing £5 and wagering it on Reel King Mega. The spins expire after three days and can only be used on Reel King Mega. Unfortunately, Slot Boss does not offer any additional bonuses.

Payment Options


Now, one of the main disadvantages of registering at Slot Boss Casino is the lack of deposit methods available to customers. At the time of writing, you can only use debit and credit cards to deposit money into your account. While the payments are credited to your account quickly and there are no fees associated, many have called on Slot Boss to add additional payment options to their casino since the current methods are lacking.

Speaking to a customer agent, we were informed that Slot Boss is looking into adding more payment options in the future. Sadly, the customer support agent couldn’t give us any more information.


You can use the above methods to withdraw money. Generally speaking, withdrawals at Slot Boss are held in a pending state for two business days before they’re sent to you, after this it can take between three to five business days for you to receive your money. Also, Slot Boss does not charge you for requesting a withdrawal, which is great.

Account Verification

After registering at Slot Boss Casino, you’ll be required to verify your account. To do this, you’ll be required to send documents to [email protected] where the customer support team will review the documents provided and approve your account. The documents Slot Boss may request can include:

  • ID: Driving license, passport or birth certificate
  • Address: A recent utility bill, payslip, council tax letter, UK driver’s license, bank statement or HMRC letter
  • Payment: Scans of the front and back of your credit or debit cards or a copy of a recent bank statement

It’s important that the documents you send to the online casino are clear and readable and the scans or picture must show the entire document. Once you’re verified, you’ll be able to deposit, withdraw and play as much as you’d like.

Customer Support

Slot Boss Casino offers great customer support, but it can be somewhat challenging reaching them. The online casino provides you with two ways to contact the support team, either by emailing them through a form on the website where you must select a topic, enter your email address, subject and then the problem. Alternatively, you can launch the Slot Boss live chat service by clicking the ‘Chat’ button in the lower right-hand corner of the screen.

Live Chat: Our Experience

When we launched the Slot Boss live chat service, we were instantly greeted by a customer support agent. We found that the agent was incredibly helpful and friendly and made sure to answer all of our questions quickly, which was great. They even discussed the lack of payment options with us and gave us some helpful information. Overall, our experience with the Slot Boss live chat service was great and we recommend you try and use it if you encounter a problem.


One of the reasons this online casino is so popular is due to its mobile-friendliness. You can download the Slot Boss app for smartphones on the Google Play Store, but it is currently not available on the Apple App Store which means Apple users will need to play in-browser, but more on that later.

The Slot Boss app works just like the desktop website, allowing you to deposit and withdraw money, claim bonuses and contact the customer support team. However, the main difference between the pair is that you can play through the Slot Boss app whenever and wherever you want rather than being stuck in one spot. This is perfect for people who are always on-the-go and rarely find time to sit at one place.

However, downloading the app will take up storage on your smartphone’s device which could otherwise have been used for something else. 

Meanwhile, Apple users will need to play in-browser to access the online casino when they want. This is done by launching your smartphone’s mobile browser, loading up the online casino and then registering or logging in. Once you’ve done that, you’re free to use the casino website as you normally would.

The one issue you need to be aware of is that older games developed with Flash are generally incompatible with most smartphone devices. This means these older games can only be played on desktop computers or laptops. 

Sister Sites

Slot Boss Casino is owned by LeoVegas, a firm which owns several other online casino websites. This means that the Slot Boss sister sites are, LeoVegas Casino, Castle Jackpot, Pink Casino, Bingo Stars, MCasino, Slot Mob, UK Casino, Bet UK and many more.

If you enjoy playing here we suggest you try out Slot Boss sister sites LeoVegas, Pink Casino and Castle Jackpot, all of which offer a great collection of games as well as several generous promotions and bonuses.


Slot Boss is a great online casino that offers a wide range of casino games and promotions. While some may be disappointed with the casino’s limited payment options, its high wagering requirements and lack of table games, there’s still enough content here to keep you busy for a long time. In addition, we believe Slot Boss is the perfect casino site for new users as the website is easy to navigate and use.

Despite this, we do hope that the online casino expands its payment options over the next few months to provide customers with more freedom to deposit and withdraw how they like. If you’ve read our Slot Boss review and believe the online casino is a great match, why not register today and give it a try?
