Thunderkick is a leading iGaming developer who creates high-end online real money slots. Known for their innovative approach, Thunderkick slots are famous for their rich designs and unique gameplay elements. Thanks to its commitment to top-notch productions, each new game they create are worth checking out.

The Thunderkick story began in 2012 when a group of NetEnt developers branched out on their own. While the provider is still relatively new in online slot software, the quality of the company’s games means it has risen through the ranks. These days, you can find Thunderkick slots at hundreds of online slot sites.

Customers and slot site operators understand the excellent mechanics, design quality, and unique concepts of Thunderkick slots. Their products have won several game awards in many important award ceremonies across multiple categories.

Hailing from Sweden and headquartered in Stockholm and Malta, Thunderkick is a reputable iGaming software developer. It falls under the regulatory watch of the Malta Gaming Authority (MGA) and the UK Gambling Commission (UKGC) through valid licenses with both.

Since launching in 2012, Thunderkick has become known for its unique feel and slick visuals, which stand out among thousands of online slot games available to players. With such excellent production quality across the portfolio, selecting the best of the bunch is difficult. But we gave it a try, and below are the tried-and-tested fan favorites you can try at our recommended Thunderkick slot sites.

Online casinos with Thunderkick slots regularly provide the top casino bonuses for new and existing customers. This helps them stand out and retain customers in a very competitive market. You will often find that your first deposit is matched with free bets while other Thunderkick casinos give away a free spins bonus. Some even provide no deposit bonuses, where you are given free credit without having to fund your account. You will need to complete any wagering requirements before you can withdraw your bonus funds. Most casino bonuses can be used on Thunderkick games, but you should always check the terms and conditions to make sure.

Thunderkick is a relatively small software provider that focuses on quality over quantity. For that reason, you will never find an online casino that solely features Thunderkick games. These are some of the other leading suppliers that you will find featured at the leading Thunderkick casinos:

NetEnt

NetEnt is another online casino games provider that was founded in Sweden. It moved most of its operations to Malta, where Thunderkick also has a base. However, NetEnt is much more giant and more established than Thunderkick. It was founded in 1996, long before Thunderkick was conceived, and it has produced hundreds of iconic games over the years – most notably Starburst and Gonzo’s Quest. Leading live casino gaming provider Evolution Gaming purchased NetEnt for $2.1 billion in 2020, so it is now part of a vast conglomerate. In contrast, Thunderkick is more of a small, independent slot producer.

Microgaming

Microgaming is another industry behemoth. It is situated on the Isle of Man. Microgaming is even older than NetEnt, founded in 1994, and it claims to have developed the first online casino software. Like Thunderkick, it is a private company, but it is significantly larger. It has released several famous online slots, including Game of Thrones, Break Da Bank, Thunderstruck, and Jurassic Park. Still, it is perhaps best known for its record-breaking progressive jackpot game, Mega Moolah, which regularly pays out eight-figure sums. Thunderkick has not yet waded into progressive jackpots.

ELK Studios

ELK Studios is yet another Swedish software provider. It has followed a similar trajectory to Thunderkick, founded in 2013, focusing on quality over quantity. It has not produced as many games as Thunderkick but has also gained plaudits for its fantastic artwork and excellent games. It also sticks to slots, so you will not find table games from ELK Studios.

Play’n GO

Play’n GO is one of the world’s most prolific producers of online slots. It stands in contrast to Thunderkick and ELK Studios by opting for quantity, as it releases a new game each week. Some have proved to be massive hits, such as Book of Dead and Fire Joker, but others quickly fade away. Play’n GO also produces virtual table games, which sets it apart from Thunderkick. It is also headquartered in Sweden, which is a real heartland for casino game creation, but it is a lot bigger than Thunderkick and was founded seven years earlier.

We aim to connect you with the best games at top slot sites. That includes playing for real money or for free. While we are the first to admit that real money slots are what most people look for, there are plenty of benefits to be gained from playing for free. Below are the main reasons to play a free game demo when visiting the top Thunderkick slot sites on this page:

• Test a game: Thunderkick has an extensive portfolio of top games, but you may prefer some slots to others. One of the best ways to know is to evaluate games by playing in free-play (demo mode). You can find out if you enjoy a slot's theme, features, and gameplay dynamics before betting with your own money.
• Practice betting strategy: There is no way to guarantee wins when spinning the reels of online slots. Similarly, no betting system will help. However, understanding the betting dynamics of a slot game can help you maximize your bankroll. Playing for free lets you become familiar with the paytable and math model on a slot before digging into your budget.
• Play without registering: Many online slot sites will allow customers to play Thunderkick slot demos without signing up. Free games are the answer to enjoying online slots without handing over your personal and financial information.
• Play for fun: Sometimes, it is nice to remember that playing games online is fun. You can kick back, relax, and enjoy the game when you play free slots. Remove the risk of playing for real money and get the gameplay experience.

Our dedicated team of professional casino players conducts an in-depth review of every single software provider represented at online casinos.

Thunderkick is a licensed and reputable developer of online slots and iGaming software. The company holds a valid license with the Malta Gaming Authority (MGA) and UK Gambling Commission (UKGC). These bodies are some of the strictest and most trustworthy online gambling regulators and hold developers like Thunderkick to exacting requirements.

While a license does not guarantee reputability, it does highlight a provider has met standards of operation and works within legal guidelines. To further enhance its credibility, Thunderkick allows QUINEL to assess all of its games. QUINEL is a leading independent testing laboratory that ensures Thunderkick slots are fair for all customers.

Therefore, every slot you play from the provider is decided randomly. Random number generators (RNGs) ensure the developer does not influence a spin. Similarly, whether the player wins or loses is down to pure chance, thanks to this technology.
