Big Thunder Slots is powered by Jumpman and was launched in 2018. It’s themed on a runaway mine train and has recently switched from the usual Mega Reel welcome offer to a version of the Matchup Bonus Wheel which offers the opportunity to win a bonus of up to 10x your deposit on not just your first deposit, but on each of your first THREE deposits.
The new offer does mean that a little bit of the theming has been dropped – the spins that could be won on the old Mega Reel offer were all on the Pragmatic Play slot Gold Rush – but who cares given that the new offer is so clearly better!
On a large screen, Big Thunder Slots looks slightly different to most Jumpman sites as the main navigation is at the side, but this is really just a cosmetic variation and on mobile, it looks the same as all the others. The games are organised into categories in the usual Jumpman way (slightly peculiar as the Casino area contains Playtech slots and you need to look in the Table Games area to find casino games, including live casino) and there’s also a search box to help you locate the game you want. New games are added at least once a week and they appear at the top of the Newest area so are very easy to find and try out.
On the whole the selection of games is excellent (as it is at all Jumpman sites), with a great combination of evergreen classics and new releases. Big Thunder Slots also has more than 30 progressive jackpot slots, mostly by Eyecon with a few other thrown in (they can’t be played with bonus, though). These are regular progressives and there aren’t any must-drop jackpots at Jumpman (plenty of games by Red Tiger but they are non jackpot versions). Like all Jumpman slot sites, Big Thunder Slots also has some bingo rooms by Pragmatic Play (exactly the same bingo rooms as you’d find at a Jumpman bingo site, in fact).
The promotions page at Big Thunder Slots is dominated by various versions of the Mega Reel that can be claimed when you deposit. Jumpman also usually have a monthly prize draw and participate in game provider promotions including Drops & Wins by Pragmatic Play.
Then there’s the Trophies page, where you can complete more than 200 achievements and level up each time you collect 5 trophies, enabling you to claim a spin of the Trophy Mega Reel (you’ll need to make a deposit before you can spin). This bit of gamification is absolutely central to why so many players enjoy playing at Jumpman sites.
An attractively designed Jumpman site, then, with one of the best welcome offers Jumpman have yet come up with.
