Thunder Slots General Site Information

This 2018 Slots Casino is already proving to be a big hit with online slot enthusiasts around the world. Currently, they are operated by the team at Jumpman Gaming. With licenses from The Alderney Gambling Control Commission who regulate for players around the world. In addition to the UK Gambling Commission who they are regulated by for players inside of the UK. Both of these licensing bodies regulate strictly to ensure player welfare is a priority by the brands they work with and this is shown clearly as this brand have a clear care for their customers. Big Thunder Slots are of course predominantly a provider of Online Slots, the clue being in the name. However, they also have alternative online gambling games including: Jackpots, Bingo, Roulette, Blackjack and more that you can visit at Slotsmummy.

The design of this site is big and bold just like its name, with a focus on a powerful purple colour scheme through-out. Whilst the design may be simple it’s effective in its purpose, catching your eye and providing an uncomplicated gaming platform. Thanks to its simplicity and use of improved navigation through menu bars and such features you’ll have no issues finding your way to the best slot games found at this site. With the navigation bar sliding out from the side giving you instant access to the all games section, promotions area, contact page and more. This navigation bar is also minimizable which is very helpful in a lot of situations.

Navigation isn’t the only simple thing on this new slots site online, they’ve kept this same simplistic ideology in almost everything they do. Including their sign-up process, where you’re only required to answer the essential questions. Provide your photo ID to verify account for withdrawals and you’ll be all set for hours on hours of playing top uk slot games online.

Mega Reel – Top Slot Bonus

This brand has some very rewarding promotional offers available at their casino site. In our personal opinion, we believe their welcome bonus is one of the best. Because it actually adds some entertainment value to it too rather than just giving you an instant standardised reward. As in their welcome offer you have to spin the Mega Reel for the chance to win some prizes. The reward you won’t know until it lands on it, which is all the fun and excitement of this offer! The jackpot prize on this slot bonus is the 500 free spins on Starburst which you can see here and also Fluffy Favourites. Although there are other prizes you could also land on including:

  • 20 Free Spins on Fluffy Favourites or Starburst.
  • 10 Free Spins on Fluffy Favourites or Starburst.
  • £10 Amazon Voucher.

Rewarding new customers is all well and good but if you’re thinking about taking up this casino seriously and becoming a regular you might want to know how you can be rewarded. Well, first of all for every £100 you deposit you get the chance at earning a spin on the Turbo Reel. This operates identical to the Mega Reel with 500 free spins being the big prize to hunt after. However, the smaller prizes have all been boosted to a whopping 50 free spins. Additionally, regulars can make the most of the VIP Scheme, getting rewarded for how much you deposit per month. Different tiers of VIP get more rewards including cashback, bonus spins & a birthday bonus.

Great Slot Game Softwares

Since this online slot site is run by Jumpman Gaming, it’s highly possible you’ve played other sites ran by this same operator such as Wizard Slots. Or maybe even read a few of our slot reviews on some of their other brands. If you have you’ll be aware of how strong their games portfolio is, in our opinion, it’s their best asset and of course, this is one of the most important factors in a good slots casino. Some of their most popular slot game titles include:

All of these 5 star slot site games are a huge hit not just with their own players but also globally. These games have received heaps of praise and awards, so it’s good that you can find not only a huge collection of several hundred slots but also the majority of them being top performers. This likely being due to the fact this brand works closely with major gaming Developers. Some of the big names include the like of Microgaming, Pragmatic Play, NetEntertainment & BetSoft casino games.

Banking & Security

As with all of our online slot website reviews, we ensure they’re all fully safe and secure to use before we release them at SlotsMummy. This one is no different, they’ve followed all the regulations and enforced strong security features. To cite a few of their key security aspects, this is things such as numerous firewalls and SSL software.

When it comes to the important process of making deposits and withdrawals at this slot site, the process is smooth. The payments are processed as fast as possible, with many payment transactions being instant. They include all the most frequently used payment types, some of which include:


When we compared their customer services to the general industry standard, we found Big Thunder Slots were at about the average standard. In essence, they do things well, but it could be improved. The first place to look is the FAQ section, this is filled with numerous issues and resolutions, so this could provide the fastest fix to an issue if you find it in here.

On the other hand, there’s a lot of instances where you need to contact their team then you can directly. With one of two ways, the first being by email, this is of course not the fastest means of getting assistance. But, generally, they will reply within one working day, usually the matter of hours. They also have a live chat feature which provides a most instant form of assistance. With real members of support providing instant replies to customers. One thing they are missing is a telephone contact number, this would provide another option for customers. This may be used by this operator in the future we hope.

The Verdict

To summarise and finally conclude this new slot site review, we’d like to say this is a top brand to play at in our opinion. There are so few faults and so much to enjoy with this one. Their games collection is second to none, a true joy to play, with so many top-rated slots. We’d highly recommend you go try this new slot website out and see for yourself.
