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 searching 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 mobile slot site via mobile devices. The Big Thunder Slots platform offers a mobile-friendly site that works perfectly well on mobile phones. 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 want to 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 want to find many secure and easy payment methods available to you, such as Pay by Phone for slot sites, Neteller and PayPal. 

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

  • Visa Debit 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 and a £10 withdrawal restriction limit. 

New customers should know that to claim the exciting welcome bonus successfully, they will not be able to use specific 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 similarities to Big Thunder Slots. These are referred to as sister sites. 

Here we have listed some of Big Thunder Slots sister sites: Express Wins slots, Elf Slots and Simba Slots.

Who Owns Big Thunder Slots

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

Big Thunder Slots is a relatively new platform operated by Jumpman Gaming but is far from being the only one. Jumpman Gaming has a selection of casino sites that 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, and 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 encounter 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 to 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 up to 48 hours. 

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

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

Final Thoughts About Big Thunder Slots

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

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

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

Another very impressive area is the available gaming options. Big Thunder Slots is packed full of games that vary from many types, whether you are looking for slots, megaways, progressive jackpots, casino games or table games.
