Thunderbolt Casino Review

With the online gambling industry in South Africa really taking off, players have plenty of options to choose from when it comes to online casinos. While this can make the search for the perfect site a bit more difficult, we always believe it is best to have options rather than to be limited to just a handful of sites. The operators which are good will always manage to stand out and so is the case with Thunderbolt Online Casino.

As the detailed 2021 review will show, this real money casino online left a good impression on our experts and while it focuses on players from South Africa, it is still very welcoming to international customers who want to enjoy the collection of games. As long as you donít mind playing in ZAR, Thunderbolt Casino is a good choice for everyone but especially for fans of video slots. South African Rand being the only currency may take some time getting used but for those logging in from ZA, it is a perfect option that keeps things nice and elegant.

There arenít really that many country restrictions as Thunderbolt seems to have a very good reach and even accepts players from the US.

When first accessing the online casino, the website will welcome you with a simple theme that has some modern touches to make it look good but not too crowded. The black background and the different shades of blue for the interface not only make the main page clean but also easy to browse through the sections for promotions, games, banking and more. It will also not take long to see that the featured titles are games from Real Time Gaming.

Having launched in 2014, Thunderbolt Casino already has a couple of years of experience under its belt and has shown that it is reliable with the help of quick withdrawals and secure banking. If problems do appear, the player support team is always ready to make them go away and answer all questions.

Security and Fair Play

Although often overlooked, online security is a major factor that must be taken into consideration when joining a new casino and depositing real money. In the same category we find that fair gaming is just as important so our experts here at CardsChat always pay the utmost attention to security and fair play.

When reviewing Thunderbolt Casino, the findings showed that the website uses key encryption technology to protect all sensitive information users share when creating accounts and making deposits. Information about the main license used by the casino online is not displayed on the website and that is a bit odd. After a bit more research, we find that Thunderbolt Casino is licensed by the Curacao eGaming Commission, one of the biggest jurisdictions for online casinos in the world.

It is included on the CDS network to allow users to easily file disputes if there are any issues but the casino is not certified by eCOGRA and the website does not provide a secure connection at all times when browsing.

Despite the room for improvement, the security at Thunderbolt is very good and the online casino takes all the needed measures to ensure flawless safety for its clients. The featured banking methods are well-known in South Africa and beyond the market.

As for fair gaming, RTG is a huge casino software developer and its games are constantly being verified by independent companies to make sure they are random in every outcome. No online casino is given access to the mechanics of the games and the way these options work cannot be modified in any way.


RealTime Gaming is widely available in the online gambling industry and it is often the only software provider at large online casinos. While some websites can add games from other developers for a richer collection, the RTG portfolio is more than enough to keep the action going on its own. It mostly has video slots, with the popular Real-Series getting a lot of attention from fans due to detailed themes, features and various progressive jackpots.

All of this and more is available at Thunderbolt Casino and a good part of the game collection is presented right on the website, with options to start playing without having to download anything first. An account is needed to play, even for the demo versions, and there are more titles through the downloadable app which can be installed on Windows computers.

In addition to slots, the software offers specialty games like craps and roulette, table games like blackjack and baccarat, video poker and more. We would have loved to see some live dealer games in the collection but we are fully aware of the lack of such options from RTG. Also, there arenít that many versions for the table games.

Players can opt for the preferred way of accessing the online casino for real money from the three available platforms, all of which are safe and secure.

  • Thunderbolt Casino Download Version - This is the recommended version for players who plan on accessing the online casino often since once the downloadable app is installed, everything is just a double click away. Setting up does take more time but the finished product has more games since not all of RTG titles are available in Instant Play. A short guide for Getting Started is presented on the site to help out new customers. The downloadable version is designed for Windows computers and laptops but can be made to work on Mac with the help of other programs.
  • Thunderbolt Casino Flash Version - Most players nowadays actually prefer to enjoy online casino games from the websites of their favorite brands. This helps save time and still has most of the gaming options available. It is enough to sign in on the site and then browse the lobby to get going. The best advantage is that it can be used on any computer and works with most of the major internet browsers.
  • Thunderbolt Casino Mobile Version - Thunderbolt Casino is keeping with the times and has a nice mobile platform for 2021 that has tens of the top games. This is available on Apple iOS, Android and other devices. Instant mobile access is provided when accessing the casino online from the mobile browser. This can also be done by scanning the Thunderbolt QR code. A downloadable mobile app can be obtained for free from the website to make sure that everything will run smoothly from smartphones and tablets. The freedom of always being able to bet real money on casino games is always exciting and the only drawback to Thunderbolt mobile casino is that there arenít that many games available. Compared to the 200+ list on desktop, mobile players will get about 37 titles to enjoy and only a couple of them are not slots. Big games like Aztecs Treasure, Caesars Empire and T Rex are included in the mobile offering at Thunderbolt Casino.
Welcome Bonus

If you donít have an account already with Thunderbolt Casino, joining comes with its own set of perks that we didnít touch on so far. The biggest of them is the R10,000 welcome bonus package that is available for the first three deposits. Not only will this offer a large amount of money for free with each payment, but it will also finish with a no deposit bonus to complete the package just perfectly.

For international players, the entire welcome offer is worth about $700. And it is not just about the maximum amounts that make the bonuses great, but also the percentages they offer.

  • 1st Deposit: 100% up to R2,500 for using the coupon code FLASHMATCH1 (USD equivalent: approximately $175)
  • 2nd Deposit: 125% up to R2,500 on deposits of at least R100 for using the code FLASHMATCH2 (USD equivalent: approximately $175)
  • 3rd Deposit: 150% up to R2,500 on deposits of least R250 for using the code FLASHMATCH3 (USD equivalent: approximately $175)
  • No Deposit Bonus: R2,500 for free after claiming the three deposit bonuses and using the code ULTIMATEFLASH (USD equivalent: approximately $175)

Each bonus coupon has a wagering requirement of 30 times for the sum of the deposit and the bonus. These requirements must be fulfilled in order to be able to withdraw the money from the account and the games that count in this regard are slots, scratch cards, keno, 7 Stud Poker, European Slot Poker, Pai Gow Poker and bingo.

While it is an industry standard to have wagering requirements for bonuses, the ones at Thunderbolt Casino are a bit high since they combine both the bonus and the deposit amounts. It can be difficult to wager so much money without losing it all so it is recommended to go for smaller payments that are easier to handle. And the bonus is clearly aimed at playing slots so this too must be taken into account to avoid any surprises later on.


Thunderbolt Casino only focuses on offering a handful of banking methods and while these are all very popular, more options would have been appreciated. The featured methods cover cards from Visa and MasterCard, along with Skrill and NETELLER to easily satisfy that majority of customers. Since these payment options are well known in South Africa and around the world, users should have no issues making deposits and withdrawals. There are also a few more options accepted.

Focusing more on cashing out, almost all of the methods can be used to withdraw, with the only exception being MasterCard. Depending on the chosen option, the minimum amounts can differ a bit.

Withdrawal Method Minimum Amount Processing Time
VISA ZAR 500 48 - 72 hours
Skrill ZAR 300 48 - 72 hours
SiD ZAR 1,000 48 - 72 hours
EasyEFT ZAR 1,000 48 - 72 hours
EcoPayz ZAR 500 48 - 72 hours
NETELLER ZAR 500 48 - 72 hours

Withdrawals are capped at R25,000 per customer per week and as mentioned before, the only available currency at Thunderbolt Casino is South African Rand. Overall, the processing times for withdrawals are pretty good and deposits are always instant.

Game Selection


Due to only having one provider, the selection of games at Thunderbolt Casino is not as impressive as the ones offered by other leading brands. There are more than 200 titles in total and these are mostly slots. Players should certainly be entertained for a long time given the long list of spinning reels and the options look pretty good. RTG has a Real Series of slots that is included at the casino online and a good part of its games have progressive jackpots that are awarded randomly after starting at $1,000. There are also some bigger progressives that are worth millions of ZAR, with titles like Shopping Spree II, Spirit of the Inca and Aztec's Millions really impressing in this regard. The big jackpots are presented as part of a scrolling banner on the main page.

The online slots cover a lot of themes and they are very similar when it comes to the betting dashboard to make sure that players can easily set the size of the bet they want before spinning the reels. While most slots have five rollers, there are also a few classics with three reels on the list.

Popular RTG slots at Thunderbolt Casino which are highly recommended include Count Spectacular, Pay Dirt, Lucha Libre, Texan Tycoon, Bubble Bubble, Green Light and Ghost Ship.

Other Games

Fans of other types of casino games or just players who want to mix things up a bit will find that Thunderbolt Casino is not limited to just one category. Its Specialty games cover Craps, American Roulette, European Roulette and a few scratch cards. As for Table Games, the 11 titles include different versions of Blackjack, Tri Card Poker, Pontoon, Baccarat and Pai Gow Poker. Nine versions of Video Poker come with flashy themes and different special features to complete the list.

Playing these other games can be just as fun and exciting as the online slots since their graphics are modern to better create the environment and make it similar to that of a real land-based casino. Players can bet at their own pace and choose from a large betting range to fit their requirements and bankrolls.

Loyalty Rewards, Promotions, and Customer Support

While we covered the welcome bonus earlier in the online casino review, we did not overlook the fact that Thunderbolt Casino has plenty of other active promotions and rewards for its customers. The first bonuses are always nice for getting started but they donít have to stop once you settled in. In fact, the casino keeps the generous offers coming every month.

  • MyBonus is a special promotion where each player gets a personalized bonus. Only customers who have deposited at least five times are eligible for this offer and they receive an invitation by email that includes a special bonus code for the promotion. This can be in the form of deposit bonuses, free spins, top up bonuses or cashback.
  • Weekend Special makes every end of the week rewarding for those who plan on betting real money at Thunderbolt Casino. This promotion includes three bonuses for every weekend that not only offer free money but also throw in a large amount of free spins. The first bonus is of 100% up to R2,000, followed by a 125% bonus up to R2,500 plus 60 free spins and then another bonus of 125% up to R2,500 and 60 free spins.
  • 150% Thundering Thursday Bonus makes the coupon code BIGTHUNDER available every week for a bonus that goes up to R2,500 on the first deposit made on Thursday. This of course has the standard wagering requirements of 30x for the full amount.
  • 10 X 50% Every Month represents a monthly offer made out of ten bonuses of 50% each with the code FLASH10 for the maximum deposit of R2,000 every time.
  • 25% Cashback makes sure that you get a second shot at winning if your first attempt doesnít go very well and your balance is under R50. The bonus only has wagering requirements of 10x which can be met on slots and scratch cards.
  • Comp Points are probably the best way to get rewards in the long run as they are calculated based on the real money bets placed on the online casino games. At Thunderbolt, R10 wagered will generate one comp point and 100 points are worth R1. The option under the cashier allows users to redeem their cash whenever they want.

It is very easy to see that the casino online is fairly generous to its existing customers and it doesnít just stop after it gets them through the door with the help of the welcome bonus. There are tens of bonuses which can be claimed every month and on top of all of that, players can always rely on the reward program through comp points to get an extra income just for betting on the games.

Customer Support

Thunderbolt Casino has a very qualified customer support team that can be reached 24 days a week, 365 days a year. The service is only available in English by email and toll-free phone. As of now, the casino online does not have a working live chat feature. The FAQ section is very limited so it is best to just contact the support staff if there are any questions since the members will gladly help out.


This is another great casino geared towards South African players and accepts ZAR. The wide array of available slot games and the option to play online or through download means that you can find your favorite game and then carry it around with you wherever you go, as long as you have a reliable internet connection. The customer support is open 24/7, though it is only in one language: English. The casino is accredited as fair and it accepts a wider selection of payment methods than is common for South African casinos. All in all, it is an excellent place to spend your hard-earned money.
