Big Thunder Slots

Big Thunder Slots is a big and bold Jumpman Gaming casino. It goes heavy on the slots and advertises big welcome bonuses and even bigger jackpots. The purple and black colour scheme is pretty much the extent of this casino’s “theme”, but as noted with sites like Viking Bingo, it’s better to keep it simple than try and fail to do something unique.

Welcome Bonuses

This first-deposit welcome deal is for new players and offers up to £200 in bonus funds when you deposit at least £10. The maximum bonus you can receive is £200.

To cash out, a 10x wagering requirement applies to the bonus, and any bonus winnings can only be converted to withdrawable funds up to the value of your lifetime deposits, capped at £250.

Loyalty Offers

Jumpman Gaming knows a thing or two about loyalty promotions, and you’ll find the same varied selection here at Big Thunder Slots.

These bonuses are ever-changing, so make sure you check the promotions page to see what’s active at the time that you play. It’s always worth doing this before you deposit, ensuring you don’t miss out on anything.

As soon as you join the site, you’ll be added to the loyalty scheme. This scheme works a little differently from the ones you’ll find at sites like PokerStars Casino. Rather than giving you points that you swap for spins or cashback, you win trophies by completing challenges.

These challenges include playing certain games, making wagers, or accessing the site on your mobile. It makes them more accessible than schemes that just require you to wager huge sums, but of course, they are still better suited to higher spenders.

Slot Games and Bingo

From Megaways to progressive jackpots and from classic slots to 3D creations, Big Thunder Slots doesn’t disappoint in the slot department. You’d expect as much from a Jumpman Gaming casino.

It also excels when it comes to bingo games. I wouldn’t put it on the same level as Foxy Bingo, which offers far more variety and a more vibrant community, but there’s still a lot happening here.

It has several different variations of bingo spread across a dozen or so games. These games cost just a few pence to play on average and every now and then there is a major jackpot to win.

One of the benefits of the Jumpman network is that even small sites and new sites can tap into a vast player base, ensuring that bingo rooms are always full.

Deposits and Withdrawals

Two of the biggest issues I have with Jumpman Gaming sites revolve around the banking options:

  • The £2.50 withdrawal fee
  • The slow withdrawals

Neither of these things should exist in a modern casino. To be honest, I would have been annoyed if I had encountered them 10 years ago.

I don’t recall ever playing at a site that charged so much for a withdrawal that wasn’t made using a credit card. I’m fairly certain that I was once paid via a cheque during my early days of gambling, and I don’t even think I was charged for that.

The slow withdrawals are more forgivable, but still, when your competitors are offering instant cashouts, you shouldn’t be taking 2/3 days.

Verdict: Big Thunder Slots Review

Big Thunder Slots is a basic but well-made casino. It features hundreds of top slots, dozens of massive jackpots, and a large welcome bonus that will appeal to all types of players. It also benefits from being part of the Jumpman Gaming network when it comes to its loyalty bonuses and bingo rooms.

As frustrating as the slow withdrawals are and as inexcusable as the withdrawal fee is, it’s hard not to like Big Thunder Slots. So, if you can get over these things, you’ll find an excellent casino that’s well worth a look.
