Slot Boss Casino Review (2026) - Exclusive Slots & Live Casino Tables

Slot Boss Casino launched in 2017 and now offers players 1,300+ casino games from leading software providers. 

The main highlights of this game's library are its extensive selection of progressive jackpot slots and growing range of exclusive titles.

In my in-depth review, I will leave no stone unturned to provide genuine expert insight.

Slot Boss Casino is operated by LeoVegas Group, a prolific operator who also run BetMGM, LeoVegas and Pink Casino.

This platform is licensed and regulated by the UK Gambling Commission (UKGC) - licence no. 39198.

Any new players at this casino can claim a casino bonus offering 50 free spins.

Slot Boss Casino Promo Code

You don't need a promo code to claim this bonus.

How It Works

• Deposit and wager a minimum of £10 on eligible casino games
• You will then receive 50 free spins for Big Bass Splash
• These free spins are valued at £0.10 each and will expire after 72 hours
• You must opt-in to receive this bonus

Wagering Requirements

This online casino UK offer has no wagering requirements.

Whatever you have left once you played through your free spins is yours to withdraw as real cash.

Is the Slot Bass Casino Bonus Worth It?

While this might not be the most generous casino bonus on the UK market, it is still worth claiming. 

Simply depositing and wagering £10 will entitle you to receive 50 no-wagering free spins on a premium slot game.

Key Benefits:

✔️ No Wagering - Whatever you win from the free spins is yours to keep as real money

✔️ Top Slot Free Spins - The free spins are for Big Bass Splash, one of the UK's most popular slots

Who Is This Bonus Best For?

✔️ This is a lower-value welcome offer aimed at slots players

I was disappointed by the lack of ongoing promotions for existing players at Slot Boss Casino. Beyond the initial welcome offer, there were no additional promotions available when I reviewed the site.

That said, the Gigantic Jackpots feature is a clear standout, with four progressive prizes available at all times. The Mega Jackpot, seeded at a minimum of £4.5 million, has the potential to deliver truly huge wins.

Unfortunately, the casino also does not currently offer a VIP program.

Users can choose between a wide range of payment methods at this casino - including bank transfer, Visa and Mastercard debit cards, PayPal and Apple Pay.

All of the withdrawals made on-site will need to be manually approved. 

Once approved, Apple Pay and PayPal withdrawals should be received within three hours, while bank transfer and debit card payments might take up to two business days.

Slot Boss is required all users complete a KYC process, as do all safe UK slot sites. 

Taking place during registration, new casino players will be asked for the following:

• Proof of ID - Passport or driving licence
• Proof of Address - Bank statement or utility bill from the last three months
• Proof of Funds - Bank statment, payslip, company accounts, tax returns

Slot Boss offers a strong library of more than 1,300 casino games.

Exclusive Slots

This casino offers a broad slots library of 1,000+ titles.

A real highlight is its growing range of exclusive games, including popular releases such as Flying Hippo, Red Hot Multipliers and Star Supreme.

Premium Progressive Jackpots

Alongside the Gigantic Jackpots feature covered earlier in this review, Slot Boss also provides a strong selection of premium progressive jackpot slots.

Its library includes 100+ progressive jackpots, featuring major jackpot networks like Jackpot King, King Millions, LotsaLoot, Mega Moolah and WowPot - all offering prizes that can climb into the millions.

Authentic Live Casino Tables

Provided by Evolution Gaming, OnAir Entertainment, Playtech and Pragmatic Play Live, this casino hosts 190+ live dealer tables.

Players can enjoy a classic mix of live blackjack, roulette, baccarat, poker and game show titles, alongside several exclusive live tables.

A standout feature is the casino’s focus on fresh live content, with featured games such as Mega Moolah Blackjack, Money Time and The Bingo Spot.

There is a Slot Boss mobile casino app that is available to download on both iOS and Android devices.

• App Store - 4.1* (50+ reviews)
• Google Play Store - 3.7* (240+ reviews)

While there are very few negative reviews across the app stores, most of the complaints come from players frustrated by a lack of wins rather than issues with the platform itself.

In my own testing, the app proved highly responsive, with smooth performance and excellent navigation throughout.
