Game Types
When you join Big Thunder Slots, you’ll be able to enjoy a fantastic games library which features more than 3,000 titles. As you’d expect from an online casino, there are plenty of online slots, but you’ll also discover the most popular table games like roulette and blackjack, alongside live dealer games, jackpot slots and bingo.
The layout of the games lobby is decent, with a selection of different categories you can browse through. The games menu also lets you pick a specific game type to view, and most of these types include further subcategories. Additionally, Big Thunder Slots has a search bar, which allows you to easily look up your favourite games.
All of the games in the casino are provided by top software developers, including:
The majority of the games at Big Thunder Slots are online slots, which you might have guessed from the name of the site. There are well over 2,000 games to discover, including popular UK classics and modern releases. The slots page offers a variety of subcategories such as Gone Fishing, Cosmic Adventure, Tales of Egypt, Mystical & Magical and Megaways.
In addition, there’s a separate subcategory for jackpot slots, with over 60 games to try out. These progressive jackpot slots offer big potential wins to lucky players, although you’ll have to open the game to see the current size of the jackpot.
Table Games
Table games are a staple of any casino, offering classic gameplay and a variety of ways to play. At Big Thunder Slots, you can see the full collection of these games in the Casino section of the main lobby menu. The range of different blackjack and roulette titles is good, but unfortunately there aren’t any other games like baccarat or poker.
Live Dealer
The live dealer section, like the casino section, only features blackjack and roulette. The main difference is that live dealers now control the action. There are lots of different versions of each game, with unique rules and bonuses to consider. However, it would have been nice to see some live baccarat and poker too.
