The majority of the platform is coloured in blue with other parts leaning more towards purple. Not too much time has been spent on the aesthetic features of this site, but Big Thunder Slots are more focused on providing a high quality gaming experience.

Casino Games 

Unlike most Jumpman Gaming operated sites, Big Thunder Slots is one that does not offer any casino games. This includes the likes of traditional table games like roulette, blackjack and baccarat. 

Big Thunder Slots is solely focused on slot lovers, offering them close to 1,000 games to play and enjoy. 

Free Spins

As a new player, you have access to a rewarding offer that provides a free spin on the Mega Reel. Mega Reels are filled with various prizes that could reward customers with up to 500 free spins. To claim this offer, a minimum deposit of £10 is required.

Play on Mobile & Big Thunder Slots App  

Mobile phones are becoming more widely used when it comes to online gaming. Many gamers prefer to use their handheld device rather than desktops or PC’s, as they offer mobile gaming. Thanks to the improvement of mobile phone technology, many online platforms work and look just as well on mobile devices. 

Many online gaming platforms are going the extra mile to release a mobile app for their customers to download on their respective app stores. Downloads are usually free and take just a few moments to complete. Mobile apps allow customers to access platforms from the phone home screen without having to search for the site via their mobile browser. 

At this point in time, Big Thunder Slots does not offer a mobile app.

However, this does not mean that you can not access their site via mobile devices. The Big Thunder Slots platform offers a mobile friendly site which works perfectly well on mobile phones. Simply search for Big Thunder Slots on your mobile browser and select their site. From here, you can enjoy their games as long as you have a stable connection to the internet. 

Payment Methods & Depositing 

If you decide to register an account with Big Thunder Slots, it will not be long before you will be wanting to make a deposit into your account and hopefully, it won’t be long after that when you are withdrawing your winnings.

When this time comes, you will be wanting to find a bunch of secure and easy payment methods available to you. 

Below we have listed the selection of payment options available at Big Thunder Slots:

  • Visa Debit cards
  • Credit cards
  • Mastercard
  • Maestro
  • Paysafe Card
  • Pay by Phone
  • Paypal
  • Neteller
  • Skrill

Processing times will vary between the available banking methods. Bank transfers typically take anywhere between 2-5 business days to complete. While e-wallets and PayPal offer much quicker processing times that can be anywhere from instant to 48 hours. 

Big Thunder Slots has a £10 minimum deposit restriction in place, as well as a £10 withdrawal restriction limit too. 

New customers should know that in order to successfully claim the exciting welcome bonus they will not be able to use certain payment methods when making their 1st deposit. E-wallets banking methods like Neteller and Skrill are often not accepted when making deposits to claim welcome offers. We advise using debit cards. 

Sister Sites 

Since Jumpman Gaming operates many platforms, you can find several sites that share many similarities to that of Big Thunder Slots. These are referred to as sister sites. 

Below we have listed some of Big Thunder Slots sister sites:

  • Express Wins
  • Elf Slots
  • Simba Slots

Who Owns Big Thunder Slots

Jumpman Gaming Limited operates the Big Thunder Slots casino website. Jumpman Gaming is a very well-established software provider that operates from its headquarters in Guernsey. 

Big Thunder Slots is a relatively new platform that is operated by Jumpman Gaming but is far from being the only one. Jumpman Gaming has a selection of casino sites that they operate at a high level. 

Jumpman Gaming has years of experience behind them of being a well-trusted and secure company. Their cashier sections are operated by Comodo and GoDaddy. Jumpman Gaming is also certified by BeGambleAware and GameStop.


Being licensed by the correct regulatory bodies is one of the most important parts of any online casino site. The following regulatory bodies license Big Thunder Slots:

  • The Alderney Gambling Control Commission
  • United Kingdom Gambling Commission

Being governed by these regulatory bodies means Big Thunder Slots has to operate and meet the strict guidelines they set. 

Support Details

One thing that is certain, is customers encountering problems when using online gaming sites – no matter how good the site is. When this happens, you as customers will expect to find various ways in which you can contact customer support to seek solutions to these problems. However, this is an area of Big Thunder Slots that falls short. 

The people behind the scenes at Big Thunder Slots strongly advise their customers to use their provided FAQ’s page to answer the majority of their queries and this detailed FAQ’s page may indeed help you. 

If you can not find your answer on the FAQ’s page, then you have one alternative customer support method available to you, and that’s the support email address. Typically, response times are not great when contacting via email and can take anywhere up to 48 hours. 

The missing live chat and toll-free telephone number are by far the biggest problems we found.

The Big Thunder Slots contact details can be found on the sites help page. 


  • Huge variety of slot games. 
  • Progressive jackpot games available.
  • Solid selection of accepted payment methods.
  • High quality mobile experience
  • Rewarding VIP scheme/Loyalty programme – birthday bonuses.
  • Plenty of casino bonuses.
  • Games for players of all types. 


  • Poor customer support team
  • No dealer games.
  • Lacks options for traditional casino fans. 
  • No mobile app.

Final Thoughts About Big Thunder Slots

No matter how good a site is, you are bound to come across some parts that need improving and this is the case with Big Thunder Slots. Jumpman Gaming has done a great job for the most part of this site, but there are a few parts like the customer support options that could be improved. 

Multiple banking methods are available that offer secure and quick deposits and withdrawals. 

One area that we feel could do with some extra attention is the customer support options. In comparison with a lot of other competitors, Big Thunder Slots fails to offer all the usual avenues of customer support.

Another area which is very impressive is the available gaming options. Big Thunder Slots is packed full with games which vary from many types. Whether you are looking for slots, megaways, progressive jackpots, casino games and table games. 

If you fancy trying Big Thunder Slots for yourself, then head to their site today!
