In a continuation on our series on slot games with the highest maximum wins, Claudia Hartley looks at games from one of the most distinctive studios in the industry, unlocking the secrets of 10 games with seriously powerful payout potential.
Hailing from Sweden, Thunderkick is one of the most exciting and disruptive slot studios of recent years. Its inimitable style, eccentric themes, and clever gameplay are what separates Thunderkick from the pack.
Though they aren’t so well known for towering max wins, recently the numbers have been climbing! So, if you’re into innovative features, and bumper wins, all packaged in a quirky style, you should probably give this studio a try.
In online slots, max wins are expressed as a multiple of your bet. So a 10,000x max win means you can win up to £10,000 with a £1 bet.

More About Thunderkick's Highest Paying Slots
Here's a bit more about each of these slots, including the features that you need to trigger to start getting close to those big max wins.
12 Bolts of Thunder
- RTP: 96.15% | Variance: High | Top Win: 30,000x
- Reels: 5
- Rows: 4
- Paylines:Â 20
- Release Date: 31.01.24
12 Bolts of Thunder offers the highest max win of any Thunderkick slot (so far!) at 30,000x your bet. It has a pretty decent default RTP of 96.15% and terrifyingly high volatility.
Inspired by Thor, God of Thunder, your job is to collect as many of his famous hammers as possible. There’s a 5-reel, 20 payline set-up and the hammers can appear on the central three reels only. Hitting 4 hammers lands you 2x the bet, while hitting the maximum of 12 hammers lands you 1,000x.
The free spins round is where things have the potential to pay much better. If you land 3, 4, or 5 scatter symbols, you start with 6, 9, or 12 spins respectively. Each time you make a ‘hammer win’ you get another 3 spins and the Hammer Ladder increases a level. You can increase to a maximum of level 5, where it’s possible to hit that 30,000x max win.
Riders of the Storm
- RTP: 96.14% | Variance: High | Top Win: 26,426x
- Reels: 5
- Rows: 3
- Paylines: 243
- Release Date: 27.02.20
Set against a moody sky with ship’s lanterns to either side of the reels, Rider of the Storm practically throws you into a pirate’s worst nightmare, a storm at sea. With an RTP of 96.14% and a max win of 26,426x your bet, it’s a storm you’ll want to weather!
Interestingly, you get to choose your own volatility upon unlocking the free spins round. Before it begins, choose from the Mechanical Engineer (lower volatility), the Huntress (medium), and the Patriarch Captain is high-risk, high-reward. Each comes with a set number of spins 15, 10, and 6 respectively, as well as a set number of walking wilds 2, 3, or 5. For those who can’t decide, there’s the mystery option, giving you a random combination of spins and multipliers.
While it might be tempting to play it safe with the good old engineer, the max win can only be achieved with the captain!
Sword of Shoguns
- RTP: 96.4% | Variance: High | Top Win: 25,200x
- Reels: 6
- Rows: 7
- Paylines: 5,040
- Release Date: 23.06.23
Set against snow-capped mountains and red acer trees, Sword of Shoguns welcomes you to an Asian pagoda. The reels are adorned with traditional weapons, fans, armour, helmets, and the shogun himself. With an RTP of 96.15%, high volatility, and the chance to win up to 25,200x your bet, this slot isn’t for the faint-hearted.
It plays out in a similar way to the Book of Ra (and co.) but with some added extras. The sword symbol is both wild and scatter, triggering a free spins round when three or more appear.
In the round, you’ll get 5-12 spins and one pay symbol is chosen to expand across all reels when it lands. If luck’s on your side, retriggers add extra spins and transform additional symbols into expanders. With up to four expanding symbols possible at any one time, it often feels as though that max win is just around the corner.
Baron Bloodmore and the Crimson Castle
- RTP: 96.15% | Variance: High | Top Win: 25,000x
- Reels: 5
- Rows: 3
- Paylines: 25
- Release Date: 19.05.21
Ready to explore a gothic fantasy? Baron Bloodmore is set on ornate reels against a blood-red sky, that shifts to a purple palace for the free spins round. It has 25 fixed paylines, high volatility, and an RTP of 96.15%.
Mystery symbols (which reveal pay symbols or wilds) are massive 3x3 blocks that can land on the middle reels during the base game and do land every spin in the bonus round. You trigger the free spins round by landing 3, 4, or 5 winged skull scatters, earning you 10, 15 or 20 free spins respectively.
The Crimson Cash Bonus Game is the highlight, activated by three castle symbols. This feature locks bet multipliers (up to x50) on the reels, resetting spins with each new hit. Fill a specific 5-symbol pattern to double your total multiplier, and watch for spawn and copy symbols that promise even bigger payouts.
Xterminate
- RTP: 94.12% | Variance: High | Top Win: 25,000x
- Reels: 6
- Rows: 5
- Paylines: Scatter Pays
- Release Date: 27.03.24
Xterminate is set in cyberpunk chaos, a city has uprisen in the background, neon buzzes and gas masks fill the reels. With terrifyingly high volatility (there’s literally a warning about it) and an RTP of 94.12% this is not a slot for those on a tight budget. But that 25,000x max win remains a prize worth playing for.
Xterminate’s standout feature is its unique multiplier, combined with an avalanche feature. Each win in an avalanche multiplies your bet for potential big-chain reactions. After each avalanche, the multiplier resets.
The bomb symbol certainly shakes things up, exploding to clear symbols and trigger avalanches when no wins appear. Charged wilds, substitute for any symbols and each have 1-3 lives. Overall, it’s a simple slot, but the powerful multiplier is what will keep you playing.
Lost City of Djin
- RTP: 96.07% | Variance: High | Top Win: 25,000x
- Reels: 5
- Rows: 3
- Paylines: 25
- Release Date: 09.05.22
Clearly inspired by Disney’s Aladdin, Lost City of Djinn is a vibrant, jewel-toned slot with a host of cheerful characters including a big, golden genie. It has high volatility, an RTP of 96.07%, and a 25,000x max win.
The aptly named Massive Mystery feature is a highlight. Here, 3x3 symbols land on the central reels, transforming into any pay symbol. The other two features are both free spins rounds - sort of. Land 3, 4, or 5, ‘free spin scatters’ to start the round with 10, 15, or 20 free spins. During this feature, you’re guaranteed a Massive Mystery every spin.
Land at least 3 ‘cash scatter’ symbols to start the Djinn Spins feature. The scatters lock in place, everything else vanishes, and for the rest of the round only upgrade, copy, or cash scatters land. Add in a pattern collect feature and this slot is positively packed with fascinating mechanics.
Bones and Bounty
- RTP: 96.16% | Variance: High | Top Win: 25,000x
- Reels: 6
- Rows: 4
- Paylines: 4,096
- Release Date: 18.10.23
With an RTP of 96.16%, high volatility, and a 25,000x max win, Bones and Bounty is only for the pirates, excuse me, players who have a strong nerve. With the shadow of a gigantic crab in the background and a ship’s monkey on the reels, it’s plenty piratey.
In the base game, the stacked respins wild symbol occupies from 2 to 4 positions and locks in place when it hits to trigger a respin. If one (or more) of these land during a respin then you get another and wins are calculated at the end.
Next is the cash bonus round. When 3 scatters fill the bonus meter, the round starts. The ‘new’ reels land blanks, cash coin symbols, persistent payers, and multiplier cash symbols. These move one space to the right after every spin and when they reach the leftmost ‘ghost reel’ they are multiplied by the reel multiplier value.
Carnival Queen
- RTP: 96.1% | Variance: Medium | Top Win: 22,700x
- Reels: 6
- Rows: 4
- Paylines: 4,096
- Release Date: 20.02.19
Set against a lively Mardi Gras scene with masked queens filling the reels, this high volatility slot packs a punch. With a max payout of 22,700x your stake, you’ll be pleased to hear that there are 4,096 ways to win.
The Avalanche feature has a powerful addition, a multiplier. Each winning cascade boosts the multiplier by 1, so big avalanches can cause big wins. However, the biggest wins come in the free spins round. Unlock this by landing 3 or more scatters, with the potential to bag more spins if you land any scatters during the round.
In free spins, the multiplier doesn’t reset on a losing spin, unlike in the base game. However, after a losing spin, a wild removes symbols in a cross pattern, creating new chances for a cascade.
Beat The Beast: Griffin’s Gold
- RTP: 96.14% | Variance: High | Top Win: 22,222x
- Reels: 5
- Rows: 3
- Paylines: 9
- Release Date: 11.11.20
Set in a Greek… Roman, some sort of Ancient temple, Beat the Beast invites you to take on the mighty Griffin and hopefully win. With a 22,222x max win, 96.14% RTP and a highly volatile maths model, you might have a challenge on your hands!
The base game is blissfully simple with 9 fixed paylines. The Griffin emblem is the key to the best bits. In the base game it’s a regular wild symbol, but it’s also a scatter, awarding 10 free spins, plus an instant payout of 2x, 20x or 200x, depending on whether you land 3, 4, or 5 at once.
The bonus round introduces a roaming wild which remains on the reels for the whole feature.. If it’s part of a win, its multiplier increases up to a maximum of 5x. If more than one is part of a win, their multipliers are multiplied together.
Midas Golden Touch 2
- RTP: 94.27% | Variance: High | Top Win: 15,000x
- Reels: 5
- Rows: 3
- Paylines: 15
- Release Date: 24.04.24
On the third iteration of this game it seems Thunderkick have finally nailed it. The max win is better for a start, but the RTP has taken a hit at 94.27%. It’s got medium volatility and is set in a stunning sandstone temple that almost glows gold with sunlight.
Wilds are pretty punchy in this game, giving multipliers whenever more than one of them is part of a win, up to a maximum of 32x. However, the free spins round is the big draw. Here, there’s a sticky respin feature, an epic wild symbol and a gift of Midas feature too. There’s a whole lot going on and plenty of potential for tiptoeing ever closer to that juicy max win.
Can You Really Win These Prizes on Thunderkick Slots?
Max win figures provided by game developers for their slots are verified by 3rd party testing houses. This is part of UK regulation and a condition of having a license from the UK regulator, the Gambling Commission. Thunderkick will have run billions of test spins on these games to verify the Return to Player, volatility and win potential. Technically the games can generate wins much higher than those published but slot developers set a limit. Once the win value from a spin exceeds that amount, the game round ends and the max win is paid out.
So it is true that these amounts can be won. However, you should keep in mind that the odds of it happening are extremely long, usually millions to 1. Whilst it does happen from time to time – check ‘slots big win videos’ on YouTube for proof – it is in fact a rare occurrence.
