Thunderkick, where to begin? This is definitely one of the most interesting casino game developers out there. Their slots come with all different RTP and volatility levels and a variety of themes.

We decided to navigate through Thunderkick’s collection of slots as they have some great games with high RTP but also a few ones with really low RTP that you should avoid.

At the beginning of this article, you will find our picks for the best Thunderkick slots. These are the slots with the highest RTPs, payouts and most entertaining features. Further down the page is an overview of recommended sites where you can play these slots as well as a list of Thunderkick’s newest slots.


In the list below, we have ranked the best Thunderkick slot games for 2024. The slots are listed in descending order, with the highest rated game first.

The main factors when we rank online slot games are RTP, payouts, features and overall enjoyment. Therefore, graphics, gameplay and slot features also play a role in the ratings.


best Thunderkick slot games - 1429 Uncharted Seas

RTP: 98.60%
Maximum win: 1,250x your bet
Min/Max bet: £0.10 – £100
Release date: April 15, 2014
Overall score: 5/5

1429 Uncharted Seas is our favourite Thunderkick slot. The main factor behind the high rating is the game’s extremely high RTP of 98.60%. In fact, in our best RTP slots guide, 1429 Uncharted Seas ranks in the top 10 – and that is when slots from all game providers are taken into account.

In addition to its high RTP, this video slot also has a good payout potential of up to 1,250 times your original bet.

1429 Uncharted Seas comes with an explorer theme. Despite being a somewhat older game, the graphics remain good. The only downside is that the game lacks some modern slot features like multipliers and respins, but if that doesn’t bother you, we can highly recommend this online slot.

Toki Time Thunderkick

RTP: 97.11%
Maximum win: 1,130x your bet
Min/Max bet: £0.10 – £100
Release date: April 21, 2014
Overall score: 5/5

Toki Time is another slot machine with a very high RTP. Compared to 1429 Uncharted Seas, this online slot has a slightly lower RTP and maximum payout, which is why it “only” ranks in second place.

You can win up to 1,130 times your stake when playing Toki Time.

The slot offers an Anime theme and has five reels and three rows. There are 11 paylines in Toki Time, which can be seen as both good and bad. For beginners it is an advantage as the slot is very easy to play, but for more experienced players it can quickly become boring. However, the game has features like wild symbols, scatter symbols, multipliers, bonus games, respins and free spins that compensate for this.

Thunderkick slot games - Riders of the Storm

RTP: 96.15%
Maximum win: 26,426x your bet
Min/Max bet: £0.10 – £100

Overall score: 5/5

The most versatile slot on the list. In Riders of the Storm, you get to choose your own volatility, making it a great slot machine for many different types of players. It is a particularly good choice for players looking for big payouts as the game has several high-paying features and a top prize of 26,426x the stake.

Also, it has most of the modern slot features you would expect, including free spins, respins and a bonus game to mention a few. One of the few things that could be improved here is the RTP, although 96.15% is still respectable.

Esqueleto Explosivo slot - top Thunderkick online slots

RTP: 97.60%
Maximum win: 700x your bet
Min/Max bet: £0.20 – £100
Release date: October 26, 2015
Overall score: 4/5

Esqueleto Explosivo is a slot with a unique theme. Whilst playing, you can expect small but frequent wins (one in every three spins on average). This is because Esqueleto Explosivo is a low volatility slot. However, if you bet the maximum, you can still win up to £70,000.

Another standout feature of the game is its high RTP of 97.60%, which is well above average.

It should be mentioned that the slot has no bonus game, but it has other fun features like respins and sticky wilds instead.

Baron Bloodmore and the Crimson Castle slot

RTP: 96.07%
Maximum win: 25,000x your bet
Min/Max bet: £0.10 – £100
Release date: May 19, 2021
Overall score: 4/5

Played across five reels and three rows, Baron Bloodmore and the Crimson Castle stands out thanks to its massive payout potential. You can win up to 25,000x your bet in a single spin, making it the second highest paying slot on the list behind Riders of the Storm.

On top of its payout potential, it also has a lot of fun features including free spins, respins, multipliers, mystery symbols and a bonus game. The only reason Baron Bloodmore does not rank higher is because of its RTP. While 96.07% is around the online slot average, it is still the lowest on this list.

Esqueleto Explosivo 2 - Thunderkick games

RTP: 96.13%
Maximum win: 5,000x your bet
Min/Max bet: £0.10 – £100
Release date: January 22, 2020
Overall score: 4/5

The original Esqueleto Explosivo became such a big success that Thunderkick decided to create a sequel. In Esqueleto Explosivo 2, you will find that the theme of the slot is the same, but other things such as game features, volatility, RTP and payouts are very different.

For starters, the RTP is lower in this game, 96.13%, which is around average. However, the potential maximum payouts are way bigger. You can win up to 5,000 times your stake if you get lucky.

In terms of volatility, Esqueleto Explosivo 2 is a high variance slot, compared to its predecessor which has low volatility.

Finally, several features of the game are different. This game has 99 paylines instead of 17, and you will not find a respins feature.

You can play Thunderkick slots at a decent number of online casinos in the UK. They are not the most popular game provider, so not every online casino will have their slots. Still, they have produced a couple of player favourites like 1429 Uncharted Seas and Pink Elephants, so a large portion of the casinos will make sure to host their games to cater for these players.

Below, you will find some of the best Thunderkick slot sites. These are reputable and well-known sites operating with a UK license and with a large selection of slots from Thunderkick.

Thunderkick is an active studio that develops new online slots every year. On average, they tend to release somewhere between three and six slots each year, so there is almost always something new to play. Some of their latest releases include Xterminate, Beat the Beast: Dragon’s Wrath and 12 Bolts of Thunder.

In the list below, you can find the latest Thunderkick slots that we have reviewed. Our favourite is Dionysus Golden Feast, which comes with a 96.16% RTP, a 7,500 max payout and four different bonus features.

Thunderkick is an independent casino game studio primarily known for its slot games. They are not the biggest game studio out there, but not the smallest either. They started their operations in Sweden back in 2012, and since then they have produced a bit more than 60 online slots.

Instead of focusing on quantity like some developers do, Thunderkick sticks to fewer games with better quality. Most of their slots come with unique themes, features and gameplay.

Their games are available in all three volatility levels – low, medium and high, making them suitable for most player types.

In terms of payouts, you can usually win between 1,000x and 10,000x your bet depending on the slot you play. While this is not as much as slots from developers like Push Gaming and NoLimit City, it is still a respectable figure around the industry average.

When it comes to RTP, Thunderkick slots are all over the place, so this is where you have to do your research before playing. The Thunderkick slot with the lowest RTP is Rex The Hunt at 92.16%, which is unacceptable as it is way below the industry average of 96%. Meanwhile, the Thunderkick slot with the highest RTP is 1429 Uncharted Seas at 98.60%, which is outstanding and one of the best in the industry.

In addition, they have produced a couple more slots with an RTP above 97% (Esqueleto Explosivo and Toki Time). Having multiple slots with such a high RTP is not very common, so this is certainly one of the areas where Thunderkick shines.

Overall, we mainly recommend Thunderkick to players who want to play classic style video slots with a modern touch. Most of their slots come equipped with popular features like free spins, respins, wilds, scatters and multiple bonus games. Moreover, as we mentioned earlier, the graphics are second to none, even for their older games.

We can also recommend Thunderkick to beginners and casual players as their slots are fairly straightforward and easy to play.

To wrap up, Thunderkick has some hidden gems in their slot selection, but also a couple of clunkers. You just have to be a little more picky about which of their slots you play. If you stick to their best slots, you can get really high RTP rates.
