Initial Thoughts

With some fantastic welcome bonuses and in-game bonus offers, the sheer variety of games offered at Big Thunder Slots will leave even the most experienced online slots player excited to log on and get spinning. At the time of writing, Big Thunder Slots offers over 450 online casino games, ranging from online slots, online casino games, bingo and many more! The welcome bonus offered is quite unique, as it is not automatically added to your online casino account. First, you must spin their Mega Reel to find out what your welcome bonus offer is. More information on this later on in the review. Whilst the super-fast gameplay and game choice are plus points for Big Thunder Slots, the welcome bonus offer could be confusing for some.


Part of the well-respected Jumpman Slots network, Big Thunder Slots uses this platform to ensure that all online slots offered are of the highest quality. For this reason alone, you know you’re going to get great casino gameplay with Big Thunder Slots. Jumpman Casino also operates many well-known online casino brands including Slots Animal, Simba Slots, Aztec Wins and more.

As a well-respected and well-known online casino brand, Big Thunder Slots offers some of the best gameplay we have seen on the market. Usually, we experience some clunky gameplay or glitches, even with the most well-known operators, but this was not the case here.

The Big Thunder Slots experience is designed to emulate a volcano or mountain, with the thunderclap theme running through various elements of the site. As the name would suggest, Big Thunder Slots is primarily focused on online slot games, however, you will also find online casino games, instant games and online bingo to name just a few. Our expert online casino review team have put Big Thunder Slots through its paces, to discover just how good this Jumpman Slots online casino site is.

Licensing & Security

Big Thunder Slots is fully licensed by the UK Gambling Commission (UKGC), meaning that you can play slots and casino games safe in the knowledge that your deposits are protected.

Big Thunder Slots Free Spins, Welcome Bonus & Promotions

Big Thunder Slots offers a unique way to play for bonus offers. In order to see what bonuses are available, you must spin the Mega Reel, which selects a random bonus amount to be added to your account. The best bonus offer is 500 free spins, but none of our reviewers was lucky enough to land on this when spinning the Mega Reel. Interestingly, spinning the Mega Reel does not always guarantee a bonus offer. Bonus offers are also sent to players via email but are only valid for 24 hours after the code is sent, making it vital to redeem the code quickly.

Big Thunder Slots Deposit & Withdrawal Options

The information offered on the Big Thunder Slots website is quite minimal when it comes to the banking options offered. At the time of writing, this is the information offered by Big Thunder Slots. The casino site accepts debit cards, PayPal, Paysafecard and Pay By Mobile payment methods.

The minimum withdrawal amount is £10 but each withdrawal under £30 carries a £2.50 administration fee, so this is worth keeping in mind when planning your withdrawals. The standard withdrawal processing time can be between 7-10 days, again worth keeping in mind when planning withdrawals.

Wagering Requirements

The wagering requirements are 65x the winnings from the Mega Reel. If you win from a bonus spin, then this will be classed as a ‘bonus fund’ at Big Thunder Slots. Winnings stored in the ‘bonus fund’ will be saved and stored until the wagering requirements are met, then a cash withdrawal can take place. You can make x2 withdrawals in any 24 hour period, but you are not allowed to make a withdrawal within 48 hours of the initial deposit being made by new players. Please note, that wagering requirements can differ between games, so it’s worth checking out the terms and conditions for each individual game.

Customer Support

Should you need some support when playing any of the online casino games at Big Thunder Slots, the customer service team are there to help you. Email or Facebook Message appears to be the best way to get in touch with their customer service team with around the clock availability.

Our Verdict


To sum up everything we’ve learned from our Big Thunder Slots research, this is an excellent casino for slots and bonus lovers. There is room for improvement, particularly in the area of customer support (one of our recommendations for superb customer service is Dream Vegas), however, this is a trusted and reliable brand with enough games to keep most players totally entertained.
