What we recommend instead
Big Thunder Slots Verdict
Like the other brands on the Jumpman Slots network, Big Thunder Slots does an average job of catering to online casino players whose expectations aren’t overly high. But, if you’re looking for a casino that offers reasonable wagering requirements, a steady supply of fresh promotions, excellent VIP rewards, and a broad selection of game types, Big Thunder Slots is unlikely to turn your head.
Design & Usability
A rather oversized advert for the welcome offer takes up much of the homepage, and the “Join Now” buttons (N.B., there are two of them) are also ridiculously large.
Rather than using images of a thunder and lightning storm as you might expect, Big Thunder Slots uses a background of rocky mountains and piles of gold coins.
The menu is a little hard to spot at first, but you’ll eventually spot it at the left-hand-side. Click on the three white bars, and you’ll get the option to view the following four pages: Trophies, All Games, Promotions, and Contact Us.
Further down the homepage, there are sections which show the accepted payment methods, the latest winners, and reasons to join the site. Underneath, there’s a random grid of game thumbnails followed by a brief introduction to the casino.
Software & Gameplay
The owner and operator of Big Thunder Slots (N.B., Jumpman Gaming) provide the software that the site runs on, and visually, it’s quite basic although it’s relatively user-friendly. While it’s nowhere near as polished as the likes of Playtech and NetEnt software, errors and downtime are rare. One improvement that we’d like to see made is the option to play games full-screen.
Safety & Security
The UK Gambling Commission and the Alderney Gambling Commission jointly licence and regulate Big Thunder Slots. There’s also an ample amount of information regarding safety and security, which confirms that the site is protected via SSL and an independently certified RNG is used to provide fair game outcomes.
Payments & Withdrawals
While it’s great to see Paypal offered, we’d like to see more banking options added as the only other choices current are Visa, MasterCard, Paysafecard, and Pay by Phone.
You can cash-out £10 or more per transaction, but if you wish to make a withdrawal, it must be for at least £30. Withdrawal requests are processed after 24 hours, and you can only request two withdrawals every 24 hours.
If the FAQs section doesn’t help you solve your own query, you can contact the support team via email or live chat. Sadly, live chat is only available midweek between 9.30 AM and 6 PM, which are off-peak hours for most online casino players.
Bonuses & Promotions
Big Thunder Slots offers six main promotions, all of which are long-term and are also offered by the other brands on the Jumpman Slots network.
The welcome offer gives you one spin on the Mega Reel when you make your first deposit of at least £10, and if you’re lucky, you’ll win up to five hundred free spins or an Amazon voucher, but according to the terms and conditions, “winning a prize is not guaranteed”. The wagering requirements for the welcome bonus are also higher-than-average at 65x.
The remaining deals include the Turbo Reel (an enhanced version of the Mega Reel) which you get a free spin on whenever you top-up your account with a qualifying deposit, double cashback for newbies, the chance to win free spins through the weekly Happy Hours promotion, and a Sunday Pizza Club offer where you could win a Pizza Express e-voucher.
No information is given about how to play on mobiles, but having carried out further research, we’ve found that you can log-in and enjoy all of Big Thunder Slots’ games via your device’s internet browser.
Variety & Originality
Big Thunder Slots boasts a games collection that is more than two hundred strong. The vast majority of titles are online slots that are manufactured by software companies such as NYX, Elk Studios, Pariplay, NetEnt, and Eyecon. They include Rainbow Riches, Fluffy Too, Fruitful Siesta, White Rabbit, Bonanza, Great Rhino, Diamond Strike, Gonzo’s Quest, and Chilli Heat.
Although the casino games and video poker games are few and far between, and not easy to locate in the lobby, you can nonetheless enjoy the likes of Jacks or Better, Blackjack, European Roulette, and Joker Wild Double Up.
Loyalty & Rewards
Every player at Big Thunder Slots is automatically enrolled in the VIP scheme, and as you play games with real cash and make deposits, you start to work your way through the four VIP levels. The perks of the scheme include birthday bonuses, weekly cashback, and Mega Reel free spins.
