Big Thunder Slots Bonuses
One of the key factors in joining a new site is that you receive additional free value for making a deposit. In terms of this particular site, you won’t be offered the conventional 100% bonus that is pretty standard on casino sites, and they will provide you with something a little more exciting and innovative.
After completing the registration process and creating a unique username, you can make a deposit. Any deposit greater than £10 will open up the exclusive Multiplier Wheel feature for a chance to win up to 10x your deposit amount. The maximum bonus you can claim is £2,000, and three spins are up for grabs across your first three deposits, giving you a potential reward of £6,000!
This bonus has wagering requirements and maximum wins; therefore, please read all the terms and conditions carefully before making a deposit.
Bonus Wagering
Any winnings from the welcome bonus must be wagered 65x. The maximum bonus conversion is equal to lifetime deposits of up to £250.
Jackpots & Promotions
Offers and promotions are subject to change. Please verify the timeliness and accuracy of any information shown below on the official website.
- Spin the Wheel – Depending on your re-deposit frequency and amount, they will allow you to spin the wheel again. This is the same wheel you spun when you made your first deposit; therefore, you know the innovative prizes available.
- Slots Tournaments — From time to time, you will notice that slot tournaments are launched for players to partake in. If they win, they will get a special prize, which could include a lot of money!
- Free Spins — Play with up to 150 free spins when you spin the reel daily!
Deposits & Withdrawals
The table displays the complete list of supported payment methods at Big Thunder Slots, along with their respective limits and payout speeds.
| Deposit Method | Min Deposit | Min Withdrawal | Est Withdrawal Time |
|---|---|---|---|
| Visa Card | £10 | £10 | 4-7 days |
| Mastercard | £10 | £10 | 4-7 days |
| PayPal | £10 | £10 | 4-7 days |
| Skrill | £10 | £10 | 4-7 days |

The minimum amount you may deposit in any transaction is £10. You can add funds using Mastercard debit, Visa debit, Neteller, Skrill, Paysafecard, PayPal, and Pay By Mobile. Deposits of £10 or £20 via Pay By Mobile incur a £2.50 fee.
All withdrawals are subject to a £2.50 transaction fee. Withdrawals will enter a pending period of 72 hours after request, with funds being credited to your account in 1-5 days.
Before withdrawing funds, you will be asked to provide a photo ID and a recent utility bill or bank statement. These are standard checks to verify your age and to prevent money laundering.
Mobile Slots App
Unfortunately, Jumpman Gaming has not invested in mobile apps for their slots sites, and they are missing a trick here, as this is something that the majority of their competitors have in place now. You can still log on to the site, typically from your mobile device, and play as usual. The website is fully responsive and functions optimally on all devices.
Promotion Codes
There is only one regular code to remember at Big Thunder Slots: PRO. This can be used along with a minimum £20 deposit every week and offers the chance to win 50-500 free spins on some of the best slot games of all time.
You will find other bonus codes issued occasionally to boost your re-deposit. These will be issued via several channels, which include:
- Mailers – You may receive a mailer through your door that gives you information on a specific bonus code that you can use (or other promotional information).
- Email – The most common method for the site to contact you with a code is via email. Sometimes, your email company will not allow these types of emails to come into your inbox and, as such, will divert them to the spam or junk folder. Ensure you allow any emails from Big Thunder Slots to reach your inbox.
- Text—If you have left your mobile telephone number with the site and allowed marketing preferences, they may text you a specific code to use.
Bingo & Slot Games
Big Thunder Slots has a decent selection of bingo game titles for customers to experience. Their bingo software runs on Pragmatic Play, which is a decent platform. Furthermore, there is a wide array of slot game providers, including NetEnt, Playtech, and Eyecon.
Game choices include the following:
- Hundreds of slots that are refreshed and updated constantly
- Jackpot slot games with a potentially massive amount of money to be won
- Access to legendary and popular titles, such as Starburst and Fluffy Favourites
- Four variations of bingo, including the Heavy Weight rooms
- Casino games and table games such as Blackjack and Roulette
- Scratch card games and other instant wins

User Experience
I have to admit, I wasn’t sure what to expect when I first arrived at Big Thunder Slots. However, I was quickly impressed by the mix of games available. Whilst it doesn’t specialise in any single category, the combination of bingo, slots, live dealer, and table games means there is something for everyone. Each game brought its own appeal, and I found myself eager to explore the wide variety on offer. The site itself is also easy to navigate, making it simple to jump between sections and discover new favourites.
What really set Big Thunder Slots apart from its competitors was the numerous promotions available. Most of them are focused on slots, but they do a great job of rewarding regular play and adding extra value to the overall experience.
All in all, Big Thunder exceeded my expectations from a slots site, and I’d happily recommend it to anyone after a lively and well-rounded online gaming platform.

Review Summary
Big Thunder Slots Reviewed: Our Verdict!
Big Thunder is a pretty snazzy and rewarding slot site for Jumpman brands. We love how easy the website is to use, how rewarding the welcome offer can potentially be, and the selection of games is undoubtedly top-notch. Aesthetically, the website is nice to look at, and from a usability perspective, it is very easy and functional to use. Obvious drawbacks include the welcome offer’s wagering and maximum win cap. The network has improved recently, with more promotions to keep you returning for more. If you are looking for a fresh new slot site to try out, this one is worth a look.
