Thunder King Slot Review

It’s based on Ancient Greece, which will definitely not be anything new to any of our players, although that has its upside too as we’ve been able to put together plenty of great online alternatives. We’ll cover them in more detail later in the feature, although they’re in place so that players in blocked Aristocrat countries don’t need to miss out on any of the fun. You’re in luck if you’re in an area where the games are available though, as there is already an online version of Thunder King and it’s loaded up and ready to go at our recommended Aristocrat partner casinos. If you’ve never had the pleasure of playing the game before, then read on for all of the details on what it has to offer in terms of visuals, gameplay and bonus rounds.

Thunder King Theme

While you may be expecting dark clouds to set off the graphics on Thunder King, the skies are surprisingly clear. Fortunately, that means that he’s probably in a good mood and will help you on your way to some good wins. The symbols in use on the game are actually among the most attractive that we’ve seen on an Aristocrat game, which are often happy to stick with functional rather than artistic. The sounds are also up to scratch for a great combination of animations and audio, so this is one of the most atmospheric Aristocrat slots that you could ever hope to play which is saying something and fits very well with the concept of the Thunder King.

Gameplay and Prizes

While the graphics and sounds were more than sufficient to draw in plenty of land based slots fans, online players have a wider range of choices and are often more concerned with the gameplay. We fall into that camp too, and it was great to see that Aristocrat matched up to the atmosphere with some of their more traditional options and winning opportunities. That said, Thunder King is slightly more extensive in the options department as the online version allows players to cover up to thirty win lines with a maximum bet of $150. The lines and coins are completely adjustable though so you can play with a single line if you prefer, or anything else in between.

Features and Bonuses

The features on Aristocrat slots are almost always where the big money is to be found and that’s definitely the case on Thunder King. The enhanced win lines are nice, but the developer often makes the overall symbol values lower to compensate, ensuring that players are always on the lookout for scatters. In this case, Mount Olympus is the symbol to keep an eye out for and it’s definitely a case of the more the merrier. For example, three scatters will award ten spins, while four bumps that up to fifteen. One on each reel makes for twenty free spins and then some truly exciting action gets underway, courtesy of the Thunder King himself. The first time he appears, he’ll fire lightning at the reels with a shot at turning them wild. He’ll always hit one, but could even hit all five. On his next appearance, he’ll turn one symbol wild at random and then hold it in place for the next spin as part of the Tornado Bonus. Finally, when he pops up once again he’ll keep things simple by dishing out a cash prize based on your coin bet. All in all, he’s one of the hardest working characters in slots and always a welcome sight!

If you want to check out Thunder King for yourself without having to head to the casino then you’re in luck, so long as you reside in a country where Aristocrat online slots are available. You’ll find this game and many more at our recommended Aristocrat casinos. If not then there are two choices. You can still find Thunder King in many casinos across Australia, New Zealand and Asia – but that means travelling! You’ll get better treatment and quicker games by playing our Thunder King alternatives, which are featured on our dedicated page here at Gamblib, with each game available for no deposit play and accessible online at some of the world’s top online casinos.
