Big Thunder Slots is an epic name, but is the casino just as attention-grabbing? Are we dealing with a loud, thunderous crack that forces everyone to take notice, or a meek and mild rumble that you mistake for a dog fart?
Let’s find out.
The Welcome Bonus promises roaring thunder, the storm of the century. But it delivers a mild breeze in a teacup.
It promises a Welcome Package of up to £6,000, but it sounds better than it is. The bonus is offered as a 1,000% match across three deposits, each with a maximum of £2,000 and a minimum qualifying deposit of £10.
The problem is that the entire bonus has a maximum conversion equal to your lifetime deposits. The offer is only available to new players, so if you deposit £10 each time, that equates to a total of just £30 and means you can only convert £30 in bonus credits.
Technically, the bonus offers £300, but this conversion term decimates that amount and takes the shine off what would otherwise be an amazing offer.
The only benefit to having such a huge bonus is that it gives you more cash with which to meet the high wagering requirement of 65x. Just bear in mind that if you make it through those requirements with a large chunk of cash left over, you will likely lose most of it.
The Welcome Bonus might not live up to expectations, but the same can’t be said for the loyalty bonuses. These number over a dozen during any given month and include some of the best offers in the industry.
They are subject to change, but here’s a summary of the offers available at the time of writing, giving you an idea of what to expect:
- Massive Monthly Giveaway: A prize draw offering numerous luxury prizes to players whose names are drawn out of the hat.
- Real Cash Giveaway: Thousands of pounds worth of cash prizes can be won during any given month. Just deposit and wager to opt-in, and if your name is pulled out of the hat, you’ll be a winner!
- Trophy Rewards: Arguably the best promotion across the entire Jumpman Gaming network, this is basically a loyalty program that tasks you with completing challenges to earn trophies. These trophies help you to advance through the levels of a loyalty program, with lots of rewards to collect on your way to the top.
- Happy Hours: For four hours every Wednesday, players can win up to 500 Free Spins. These spins have the same terms as the Welcome Bonus.
- Winner Winner Chicken Dinner: Rewards a £50 Just Eat Voucher to the player who secures the highest single spin win. It’s a nice little promo, though it focuses on monetary value and not win ratio, so it usually goes to players who bet in the hundreds and have won over £40,000. In other words, they are the ones who care the least about free food. If you have just banked £40k, would you really care about a free pizza?
Slots and Other Games
Great slots, good Live Casino games, and surprisingly varied bingo rooms—that’s what’s on offer here. It’s everything you would expect from a Jumpman Gaming casino, and it all comes wrapped in a neat Jumpman package.
The member’s area is attractive, streamlined, and easy to navigate. The site also adds new slots, Live Casino games, and table games on a regular basis and if you prefer to play on mobile, it supports both Android and iOS platforms.
Keep your eyes peeled for the jackpot slots, as well as special jackpot bingo rooms, the latter of which usually land on Friday and Saturday and offer tens of thousands of pounds in prizes.
Depositing and Withdrawing
If you’re going to stick with a casino over the long haul, it’s important for it to have good loyalty bonuses, which Big Thunder Slots definitely has. But it’s just as important for it to process withdrawals quickly and make sure those withdrawals are easy and free.
That’s definitely not the case here.
All withdrawals incur a fixed fee of £2.50, and that’s true regardless of the method used. They also take much longer than they should and can drag on for between 1 and 5 working days.
PayPal is accepted, which is definitely a positive, but it’s neither free nor fast, so what’s the point?
Big Thunder Slots Review Summary
As with many Jumpman Gaming casinos, Big Thunder Slots is let down by its Welcome Bonus terms and its withdrawal process, but if you can ignore these issues and focus more on the great games and loyalty bonuses, there’s a lot to like.
It’s far from perfect, but most players are just looking for a new place to collect a few decent offers these days, and Big Thunder Slots definitely ticks that box.

Big Thunder Slots FAQ
Can I Play Big Thunder Slots in the UK?
The United Kingdom is one of the casino’s main target markets, which is why it operates under license from the Gambling Commission of Great Britain. It is also available in other countries; in which case the Alderney gaming license applies.
Is Big Thunder Slots Just a Casino?
Big Thunder Slots might have “Slots” in its name, but that’s definitely not all it has to offer. As noted in my review above, Big Thunder Slots also has a Live Casino and a dedicated bingo section.
What is Customer Support Like?
I have run several experiments on Jumpman Gaming’s customer support teams in the past and they never end well. At best, they are unhelpful, but most of the time they just ignore me. They will be there to help if you have a serious account issue, but if you have a simple question to ask, you’d be better off checking the FAQs, using Google, or just giving up entirely.
What Payment Options Are Accepted at Big Thunder Slots?
Big Thunder Slots accepts several different payment methods. The best of these is PayPal, as it’s the quickest and easiest. You can also use Pay By Mobile and PaysafeCard, as well as popular debit cards. If you’re using Pay By Mobile, bear in mind that you will be charged a fixed fee of £2.50 for deposits, along with the fixed £2.50 withdrawal fee.
