Software and Range of Games


Our review starts with games offering at this site. Players will of course notice that the casino is geared towards online slots. The clue is in the name. In fact, other types of games are almost completely ignored. This makes the site suitable mainly for playing slots and nothing else.

Online Slots

The majority of the casino’s online slots come from Microgaming and NetEnt. This means that most games won’t be new to regular slots players. At the same time, it’s good news as these games are incredibly high quality. New players should certainly check out popular slots like Starburst, Gonzo’s Quest and Immortal Romance.

There are more interesting slots from smaller providers. Devlopers include Barcrest (who created the massively popular Rainbow Riches series), Nyx Interactive and Yggdrasil Gaming. New slots are added often, plus most can be played on mobile. The wide selection of slots is one of the most impressive features of the casino.

Progressive Jackpot Slots

Progressive slots fans can choose from 44 titles, a large amount for any online casino. Players will flock to Mega Moolah, which always promises a large progressive jackpot. It has been known to reach £13m before. Other progressive slots to try here are Caravan to Cairo, Ozwin’s Jackpots and Stampede. Progressive jackpot games have their own dedicated section at this site. This makes it easy to browse through the different titles on offer.

Table Games

Looking for table games at Big Thunder Slots? Unfortunately, there are only four of them to play. Two blackjack and two roulette titles don’t make for a great table collection. Excluding baccarat is an oversight here. There’s no craps or casino poker either.

Live Casino Games

Live casino games are also excluded from this site. This is one of the more disappointing aspects of our Big Thunder Slots review. For live games, players will have check out one of the other casino sites we’ve reviewed.


As the site is powered by Jumpman Gaming, it’s in the hands of bingo experts. There are 10 bingo rooms to choose from at Big Thunder Slots. This gives players a chance to take a break from slots and try something different. Bingo rooms have varying prizes, with some prize pools in excess of £1m. Buy a ticket for just 1p, or the most expensive ticket for 50p. There are also two free rooms which offer real cash prizes. This is perfect for playing without risking any real money. The bingo section is a terrific addition to this online casino.

Bonuses and Promotions


Bonuses and promotions are key to a successful online casino. Luckily, there are plenty of bonuses for everyone at Big Thunder Slots.

Welcome Bonus

The welcome bonus here is similar to others you’ll encounter on Jumpman Gaming sites. It’s a bit of a gamble. Rather than getting a certain bonus upon signup, take a spin of the Mega Reel. This could reveal 500 free spins on Starburst, or even an Amazon voucher. On the other hand, it might be nothing. This risk means players could get no reward for placing their first deposit.

Winning free spins has a slight disadvantage at this casino. The wagering requirement is 65x, which is huge. This means being able to withdraw winnings from this bonus will be difficult. Even if the requirement is met, the maximum earning from this bonus is just £250. This bonus would be much better if the terms and conditions were more relaxed.

Loyalty Rewards and Promotions

A top loyalty scheme adds another level of play to a casino. This is exactly what players will find at Big Thunder Slots. Everyone starts as a Newbie and has four tiers to climb – the highest being Legend. Get cashback on all tiers except Newbie, plus receive free spins and a birthday bonus. One point is earned for every £1 deposited. This loyalty scheme will keep players dedicated and willing to climb the ranks.

Newbies Cashback Bonus

For the first month only, Newbies in the loyalty scheme will earn 1%. This drops back down to zero after the first month ends. However, reaching higher tiers during the first month will get your cashback doubled! This bonus is ideal for players to start profiting off the loyalty scheme.

Turbo Reel

The Turbo Reel is a fantastic bonus for high rollers. Depositing larger amounts, of £100 or more, could unlock this special wheel. Spin the wheel to discover the prize. It’s similar to the way the welcome bonus works. The smallest prize is 50 slots spins, while the biggest is a massive 500 spins.


At Big Thunder Slots, earn trophies by completing challenges or playing certain games. It’s like playing games in order to play games! Trophy collecting is a way to add even more excitement to the casino. Win trophies to advance through levels – every new level means an extra Mega Reel spin.

200 Club

Anyone who wins 200 trophies will unlock the 200 Club bonus. This isn’t a common bonus like free spins though. Instead it sees the lucky player being emailed an Amazon gift voucher. This is automatic upon reaching 200 trophies, so there’s no need to claim the prize.

Happy Hours

Happy Hours allow players to win free spins simply by signing in. They take place from 3pm until 7pm every Wednesday. Visit the casino between these hours to win anything up to 500 free spins. It’s certainly worth paying a midweek visit to this site.

Winner Winner Chicken Dinner

Finally, there’s the simplest of all bonuses at this site. Throughout each month, the casino records the highest single spin wins on slot machines. The player with the highest win gets a £50 Just Eat voucher at the end of the month. This is another automated bonus – look out for an email if you’ve won.



Deposit money at Big Thunder Slots using a credit/debit card, PayPal or paysafecard. Another less common option is paying via a mobile phone bill. The casino does not however support Neteller or Skrill deposits, which is unusual. The minimum deposit is just £10, plus there are almost no fees for depositing. There is a fee to the payment provider when depositing using a mobile phone bill. Any deposits are credited to a player’s account within seconds.

Players must use the same banking method for withdrawals and deposits. If this is impossible (such as mobile phone bills), another method can be nominated. Players need to have ID at hand when requesting a payout for the first time. Withdrawals have a 72 hour pending period, which means this site doesn’t offer fast payouts. There are however there are no withdrawal fees. Like deposits at this casino, the minimum withdrawal in a single transaction is £10.

Security and Fair Play


Big Thunder Slots is licenced by the UK Gambling Commission, which is a very trustworthy body. It’s safe to play here, with an authority keeping an eye on fair treatment of players. It is also a licenced by the Alderney Gambling Control Board. Although not as well known, it further proves that this casino takes safety seriously.

As for the games, there is an SQS certificate for this site. This means games have all been tested and confirmed as completely fair. This helps players feel confident when spinning the reels for the first time. As with all good sites, SSL encryption is also used. Thanks to this, unauthorised third parties can’t get their hands on player information.

When it comes to customer support, live chat is ideal. This method is very convenient for members. If you’re not yet a member, email is the only contact option. No phone support is offered at all. Contacting the site via their Facebook page is the only other option available. The FAQ section isn’t comprehensive either. This can be annoying if you’re looking for further information before committing to sign up. You’ll have to get in touch via email, which can feel more longwinded.

Mobile Casino


In our Big Thunder Slots mobile review, it was a seamless transition to playing on mobile. This is the case regardless of the device used – Android, iPhone and iPad. To play, simply navigate to the site on any mobile browser. A perfectly optimised mobile casino site awaits.

On the mobile website, there are hundreds of different online slots. Almost the exact same offering as desktop is on display. Mobile players won’t miss out on prizes, bonuses or promotions either. The only slight problem with mobile is the lack of a Big Thunder Slots app. This isn’t a huge issue, as the quality mobile website is more than adequate. Lots of casinos are launching apps in 2022, so it could be in the pipeline.



Our comprehensive Big Thunder Slots casino review has made it clear that this casino is for slots players. Anyone who loves spinning the reels will find hundreds of titles on desktop and mobile. Those who want to enjoy table or live dealer games won’t be overly impressed. We were disappointed to see that these are almost completely neglected.

Banking here is pretty straightforward and had no surprises. There can be no doubting the fact that this is a safe and secure casino site. All players at Big Thunder Slots will be able to claim plenty of bonuses. The range is exciting and includes a potentially massive welcome bonus. However, the wagering requirement for many of the bonuses is rather high. This online casino displays fantastic qualities in most of our scoring categories, but there are aspects to work on. For slots fans – go ahead and join without hesitation!
