Thunderkick Casinos — Games, Fairness and Where to Play
Thunderkick is a video slot studio founded in 2012 by former NetEnt developers, according to iGaming Express, and it has kept a narrow focus ever since: it builds only video slots, no table games, live casino or crash titles. That narrowness is the point of this page — before chasing a specific title, it helps to know who tests the studio's games and how wide its RTP range actually runs.
Who Is Thunderkick
Thunderkick set out in 2012 as a small studio looking to shake things up, according to the company's own about page, and it is headquartered at Vasagatan 11, Plan 8, Stockholm, SE-111 20, Sweden, with a dedicated subsidiary, Thunderkick Malta Limited, operating out of 2 The Bastions Office, Emvin Cremona Street, Floriana FRN 1281, Malta. Jan Lunde serves as CEO and Commercial Director, and per the studio's own site, Thunderkick has grown to a team of more than 80 people split between Stockholm and Malta.
Across our catalogue of 511 slot studios ranked by how many casinos carry their games, Thunderkick sits in 15th position by that measure. For scale, Hacksaw appears in 121 casinos in our records and Jili in a single one, with Zerplaay Games (5), Big Time Gaming (96.44) and Spribe (104) sitting between those extremes — Thunderkick's distribution lands well above that midpoint but behind the small group of studios integrated almost everywhere.
Thunderkick Games and Signature Mechanics
Thunderkick's catalogue counts 96 video slots as of 2025-2026, and the studio has already announced its 100th release on its official site. Every game is developed and designed within the studio's own team rather than outsourced, per Thunderkick's about page, running on an in-house Remote Gaming Server and HTML5 engines built specifically for the brand. There are no table games, live dealer studios or crash games in the lineup — the entire portfolio is slots, distributed to operators both through direct B2B integration and via aggregator programmes, including participation in Relax Gaming's Powered By network.
What separates the portfolio from a generic slot library is less any single mechanic than the consistency of execution: bright, stylised animation and a recognisable visual identity carry across releases, alongside varied bonus structures built around reel modifiers and feature buys rather than a single repeated template.
Thunderkick RTP, Volatility and Fairness
Thunderkick's slots carry theoretical RTPs ranging from 93% to 98%, with an average around 96.1% for titles released before 2020 and a recorded high of 98.50% on 1429 Uncharted Seas. Releases from 2023 to 2025 have settled lower, in the 94.0-94.3% range, and the highest recorded maximum win in the portfolio sits at 30,000x the stake, on 12 Bolts of Thunder. RTP is a theoretical figure calculated over a long run of spins, not a promise for any single session, and volatility across the catalogue skews high — larger but less frequent wins are the trade-off, not a guarantee.
Fairness rests on independent testing rather than marketing claims. Thunderkick's games have been tested and certified for RNG fairness by QUINEL, one of the industry's established testing laboratories, according to SoftGamings' documentation of the studio. On the licensing side, the studio holds an MGA/B2B/248/2013 licence from the Malta Gaming Authority, issued in 2013, and Thunderkick AB and Thunderkick Malta Ltd are licensed and regulated in Great Britain by the Gambling Commission under account numbers 40165 and 41752. Additional permits cover Spelinspektionen in Sweden, ONJN in Romania since 2020, Spillemyndigheden in Denmark with a licence running to 2029, Alderney, Lithuania, Germany, the Netherlands and AGCO in Ontario.
Thunderkick's Danish licence with Spillemyndigheden runs through 2029, one of the longer confirmed validity windows among the studio's regional permits.
Where to Play Thunderkick Games
The casino list above this article draws on our own catalogue of ~319 operators that carry Thunderkick's slots, including Beef Casino, 20bet and Tsars. Across these hubs, there are 845 active bonuses on offer, with wagering requirements averaging 27x (minimum 1x), match bonuses up to 600%, and 307 of them including free spins. Rather than repeating that list, it is worth knowing what actually changes between operators once the provider is confirmed present.
- Casino licence — the regulator governing the operator, not the studio, decides local availability and dispute handling
- Region availability — Thunderkick titles are not switched on identically in every country a casino serves
- Demo access — some operators gate demo play behind registration, others allow it freely
- Payment method fit — a wallet like Neteller may clear faster on one operator than another even with the same provider catalogue
Operators broadly licensed and reviewed on this site, and mobile-optimised where relevant, are collected in the Licensed Casinos and Mobile Casinos hubs, which is a faster way to narrow the field than scanning individual reviews one by one.
Common Misconceptions About Thunderkick Slots
- "A slot is due for a win" — Thunderkick's RNG, tested by QUINEL, generates each spin independently; no past result changes the odds of the next one.
- "Higher RTP always means a smoother session" — RTP of 98.50% on a title such as 1429 Uncharted Seas describes the return over a long run of spins, not what a short session will pay out.
- "All Thunderkick slots play the same" — the portfolio's RTP spread runs from 93% to 98%, and volatility skews high across most titles, so risk profile still varies title by title.
- "A licensed studio means every casino offering its games is equally trustworthy" — Thunderkick's own MGA and UKGC licences cover the studio, not the operator distributing its games; each casino's own licence still needs checking separately.
How Thunderkick Casinos Differ
Once a casino carries Thunderkick's catalogue, the sharpest practical difference between operators is how many countries each one actually accepts players from — stated affirmatively as acceptance, not as a block list.
| Casino | Countries Accepted |
|---|---|
| Casoo | 249 |
| Tsars | 247 |
| Trickz | 245 |
| Thunderpick | 244 |
| GranaWin | 190 |
| Wisho | 20 |
| Casino | Currencies Accepted |
|---|---|
| Slotsgem | 50 |
| 20bet | 49 |
| Ivibet | 48 |
| SafeCasino | 48 |
| Flagman Online Casino | 11 |
| Wisho | 1 |
The gap is wide enough to matter: Casoo accepts players from 249 countries against Wisho's 20, so a player's own location, not just the presence of Thunderkick games, should decide which of these operators is even reachable.
Ownership is a separate filter worth naming. Per our records, of the 83 brands tracked in this selection, 10 run under the RoyalPartners programme and 5 under CatPartners — meaning several outwardly distinct casinos in this pool share one operator, one support structure and one dispute-handling policy behind the scenes.
Verdict on Thunderkick Casinos
"Thunderkick's value is in a tight, in-house catalogue tested by an independent lab — it suits players who prefer a focused slot library over breadth of game types."
Thunderkick fits players who want video slots specifically, are comfortable with high volatility and want a studio whose RNG testing and licensing are named rather than assumed. It is a narrower recommendation for anyone looking for live dealer tables or crash games in the same catalogue, since Thunderkick does not build either — that choice sits with the casino's other providers, not with this studio.
Gambling is entertainment, not a way to make money or fix finances. Set deposit and time limits, take regular breaks, and use self-exclusion tools if play stops feeling like fun. Licensed operators provide these tools — using them is a sign of control, not weakness. Learn more on Responsible Gambling →
