Thunderkick
Thunderkick is a Swedish slot studio that Irish players will recognise from the game logos in a casino lobby rather than as a casino brand in its own right. Founded in Stockholm in 2012, it built a name by releasing fewer games than most rivals and putting more thought into each one. You will find its slots at the casinos listed on this page, running on the same account and payment systems those sites already use.

Who Thunderkick are
Thunderkick is an independent studio, not part of one of the large gambling groups. Like NetEnt, it grew out of the Stockholm slot scene, though it has always stayed smaller and more selective. That independence shows in the games. Rather than churn out dozens of near-identical titles, the studio tends to release a handful a year and give each its own art direction and maths. It runs its own remote gaming server and its own game engine, so the whole thing, from the animation to the way a bonus round pays, is built in house.
If you have played online slots in Ireland for any length of time, you have probably met their work already. Esqueleto Explosivo, with its singing Day of the Dead skulls, is the one most people name first. Pink Elephants, the Beat the Beast series, Midas Golden Touch, 1429 Uncharted Seas and Arcader are Thunderkick titles too. There is a recognisable house style: clean interfaces, a bit of humour, and a willingness to try a mechanic that does not turn up in every other game.
The games and how they play
Thunderkick makes video slots and little else. No live dealer tables, no bingo, no sportsbook. If you see those on a site that also carries Thunderkick, they have come from other suppliers sharing the same lobby.
The slots are built in HTML5, so they run straight in the browser on a phone, tablet or laptop with nothing to download. Android and iOS both work fine through the mobile browser. Return to player figures usually sit around 94 to 97 percent, though the exact number can differ between operators because some markets allow more than one RTP version of a game. Check the figure in the game’s own information screen before you play, since that is the only place it is guaranteed to match the version you are on.
Volatility is where Thunderkick has a bit of a reputation. A good few of their slots run medium to high, which means quieter spells between wins and more of the payout tied up in the bonus features, often free spins rounds with multipliers stacked on top. That suits some players and frustrates others, and it is the single thing worth knowing about the studio before you sit down with one of their games.
Tested and certified, not licensed to you
Every Thunderkick slot uses a random number generator to decide outcomes, and independent test houses check that generator along with the game maths. The checks confirm that each spin is independent of the last and that long term payouts match the stated RTP. Thunderkick itself holds supplier approvals in established jurisdictions, including the Malta Gaming Authority and the UK Gambling Commission.
Those are supplier approvals, though, not a licence that covers you as a player. The licence that matters for your protection belongs to the casino you actually deposit with, and that is where the Irish picture is changing.
The Irish regulatory reality
For years there was no dedicated Irish licence for online casinos. Sites accepting Irish players did so from offshore, most often under a Malta licence, and Irish law had not really caught up with online play. That is now being replaced.
The Gambling Regulation Act 2024 set up the Gambling Regulatory Authority of Ireland, the GRAI, which is standing up in stages. Remote betting licences went live from July 2026, with remote casino licences expected to follow later in the rollout across 2026 and into 2027. The Authority is also building a National Gambling Exclusion Register, an Irish equivalent of the UK’s self exclusion scheme that every licensed operator will have to join, along with a ban on credit card gambling and a watershed on advertising.
For a player, the short version is this. Right now most casinos carrying Thunderkick still operate under offshore licences while the Irish regime beds in. Over the next couple of years you should see Irish licensed sites, Irish self exclusion and Irish complaint routes become the norm. That is a real step up on the offshore setup, and it is worth favouring operators that are moving early towards GRAI standards.
Paying in euro
Deposits are in euro at Irish facing casinos. Debit cards remain the common method, though it is worth knowing that some Irish banks decline gambling transactions on a card, which catches people out. E-wallets are the usual fallback, and open banking style bank transfers are becoming more common and tend to clear quickly. Credit cards for gambling are on the way out under the new rules, so do not count on them.
The verdict for Ireland
Thunderkick is a small studio doing distinctive work, and its games are a genuine reason to like a lobby rather than a name to skip past. For Irish players the games themselves are the easy part. The thing to watch is the licence behind the casino you choose, because the Irish market is mid transition and the protections are still landing. Pick a well run site from the casinos listed on this page, check the RTP in the game screen, and treat the high volatility titles with the caution they deserve.
Is Thunderkick legal to play in Ireland?
Yes. Thunderkick supplies slots to casinos that accept Irish players. Historically those sites operated under offshore licences, most often from Malta. Ireland's new Gambling Regulatory Authority (GRAI) began issuing remote licences in 2026, with remote casino licences following as the regime is rolled out, so Irish licensed sites carrying these games are on the way.
Which Thunderkick slots are the best known?
Esqueleto Explosivo is the title most Irish players recognise first, thanks to its exploding Day of the Dead skulls. Pink Elephants, the Beat the Beast series, Midas Golden Touch, 1429 Uncharted Seas and Arcader are other well known Thunderkick games.
Are Thunderkick slots high volatility?
A good number of them are medium to high volatility, which means longer gaps between wins and more of the payout tied up in bonus features. Return to player figures usually sit around 94 to 97 percent, and you can confirm the exact RTP in each game's information screen.
Is Thunderkick licensed by the GRAI in Ireland?
Thunderkick holds supplier approvals from regulators such as the Malta Gaming Authority and the UK Gambling Commission. B2B game supplier licensing under Ireland's GRAI is expected later in the rollout, into 2027 and beyond, so for now the licence that protects an Irish player is the one held by the casino itself.
How do I deposit in euro to play Thunderkick games in Ireland?
Irish facing casinos take deposits in euro by debit card, e-wallet or bank transfer, and open banking payments are becoming more common. Note that some Irish banks decline gambling card payments, so an e-wallet is a useful backup. Credit card gambling is being phased out under the new Irish rules.
