Thunderkick slots on mobile

Thunderkick slots on mobile: what to expect

Thunderkick makes video slots with offbeat themes: exploding Mexican skulls, pink elephants, birds sitting on telephone wires. You play them on your phone through the lobby of a UK-licensed casino app or mobile site, not through a Thunderkick app, because studios supply games to operators rather than to players directly.

The studio has kept its catalogue tight, at about 110 games on reference listings, and none of them are based on films, TV shows or other licensed brands. That gives the library a consistent personality. For a wider view of how studios compare, start at our slot providers hub.

Like other modern online slots, Thunderkick games load in the casino app’s game window, so they play on iPhone and Android alike.

Who is Thunderkick? An independent Swedish slot studio

Thunderkick was founded in 2012 and is headquartered in Stockholm. It is independent rather than part of a large listed group, which sets it apart from studios such as NetEnt (owned by Evolution) or Quickspin (owned by Playtech).

Its licensed companies are Thunderkick AB and Thunderkick Malta Ltd. In Great Britain it appears on the Gambling Commission register under two account numbers, 40165 and 41752. Thunderkick is also a Powered By partner of Relax Gaming, one of the partner programmes Relax runs alongside Silver Bullet.

Is Thunderkick licensed in the UK? How to check

Yes. Studios that supply games to British players need a Gambling Commission licence of their own, and Thunderkick’s accounts can be looked up on the Commission’s public register of businesses (opens in a new tab). The casino app you play in needs its own operating licence too.

1. Open the Gambling Commission public register in your phone’s browser.
2. Search the businesses list by name (Thunderkick) or by account number, 40165 or 41752.
3. Open the entry and check the status shows the licence as active.
4. Separately, check the casino app’s licence number, usually shown in the app’s footer or terms, against the same register.
5. If either check fails, don’t deposit; our guide on spotting an unlicensed casino app explains the warning signs.

A UK licence is what brings the stake limits, design rules and complaint routes described below. Our answer to how do I know a casino app is licensed? goes into more depth.

Thunderkick games from low to high volatility

Thunderkick’s RTPs are tightly grouped, so the bigger difference between its games is volatility: how bumpy the ride is. Ordering the games this way makes it easier to pick one that matches your budget.

Low volatility, as in the first Esqueleto Explosivo, means smaller wins arrive more often and the top prize is modest. Pink Elephants 2 sits at the other end, with a higher ceiling and longer gaps between meaningful wins. Neither changes the long-run cost much, because the RTPs are within a fraction of a point of each other.

How Thunderkick’s exploding and dropping reels work

The studio’s signature idea is that a win removes symbols and lets new ones fall in, with a multiplier that grows as the chain continues. Each game puts its own twist on it.

Esqueleto Explosivo: chain multipliers with no bonus round

Winning skulls explode and new ones drop from above. Each explosion in a row pushes a win multiplier higher, up to 32x, and the wild blows up neighbouring symbols when it lands. There is no separate bonus spins round, which is unusual and keeps the game’s rhythm the same throughout.

Esqueleto Explosivo 2: the Mucho Multiplier

The sequel moves to 99 pay ways. Drop wins and the Explosivo Wild both raise the Mucho Multiplier shown beneath the reels, and three or more scatters trigger bonus spins that carry the Mucho Multiplier and can be retriggered.

Birds On A Wire: falling birds and the Inwinity Spin

Winning birds leave the reels and the birds perched above drop into the gaps, with each further win in the same spin paid at a higher multiplier. A black rooster is the wild. Bonus symbols award 10 bonus spins, with two more for each extra bonus symbol up to 34, and the round ends with an Inwinity Spin that keeps going until a win lands.

Midas Golden Touch takes a different route, with sticky re-spins that hold winning symbols while the other reels spin again. The multiplier glossary entry explains how multipliers change a payout.

What Thunderkick max wins mean at your stake

A max win is quoted as a multiple of your stake, so it scales with what you bet. This table turns the published caps into pounds. These are the most a single spin or feature can pay under the game rules, and reaching them is extremely rare.

The cost side of the same games

The expected cost is total staked × (100% − RTP). On £50 of stakes, Esqueleto Explosivo at 96.0% has an expected loss of £50 × 4% = £2.00, and Pink Elephants 2 at 96.13% has £50 × 3.87% = £1.94. The averages are almost identical; what differs is how widely a single session can swing. Our page on RTP on mobile explains why short sessions rarely match the average.

Playing Thunderkick slots on iPhone and Android

Thunderkick games open inside the casino app’s game window, so the app’s own requirements decide which phones are supported. Check the minimum iOS or Android version on the store listing before you install. Our guide to installing a casino app on Android and the iPhone download guide walk through it.

Pink Elephants 2 shows 24 symbols at once on its 6x4 grid, compared with 15 on a 5x3 game, so it can feel busier on a small phone; rotating to landscape, if the casino’s client allows it, gives the reels more room.

Because the reels are rendered on the device, a slot session uses little data compared with streamed live tables. If your signal drops mid-spin, the result is settled by the game server; our page on what happens if your app crashes explains how.

Thunderkick and Relax Gaming’s Powered By network

Thunderkick’s link with Relax Gaming is a distribution partnership, not an ownership one. Relax, founded in 2010 and licensed by the Gambling Commission under account 37462, runs the Silver Bullet and Powered By partner programmes for other studios.

For players, the practical effect is reach: a casino that integrates Relax content may have an easier route to Thunderkick titles. It doesn’t mean every Relax-connected app carries them, so search the lobby. If you enjoy Thunderkick’s cascading style, studios with their own distinctive mechanics, such as ELK Studios and Nolimit City are worth comparing.

UK rules that shape Thunderkick slots in apps

British players get the same Thunderkick games with UK-specific limits applied by the casino and the game client.

The Commission’s responsible product design standard (opens in a new tab) sets out the speed and autoplay rules, and GOV.UK’s announcement of the £2 maximum stake for under-25s (opens in a new tab) explains the younger players’ limit. Feature buy-ins are not offered to British players, following a Gambling Commission warning in January 2020. See our autoplay ban page for more.

Where to play Thunderkick-style slots with a welcome offer

No partner offer is tied to a Thunderkick game, and we can’t confirm which partner lobbies carry the studio, so check the app’s game lobby. The three offers below are slot offers with no wagering on what the spins pay, and all are for new customers aged 18+, with terms applying.

• PlayOJO: make a first deposit of £10 or more as a new UK customer (Northern Ireland excluded) and get 80 free spins on Big Bass Bonanza at 10p each. There’s no wagering, so winnings come as cash; the offer can’t be combined with others and is claimed only through the designated offer link.
• Coral Casino: between 1 October 2026 and 1 February 2027, bet £10 or more on slots after depositing to get 100 free spins at 10p on selected games. Accept them within 48 hours and use them within 7 days; winnings carry no wagering. Neteller, PayPal, Paysafe, Skrill, prepaid card and certain debit card deposits are excluded.
• Ladbrokes Casino: spend £10 or more on slots after depositing and get 50 free spins each day for the first 10 days, up to 500 in total, at 10p on selected games. Claim each day’s spins before 23:59 and use them within 7 days, with no wagering. Deposits by prepaid card, PayPal, Paysafe, Neteller, Skrill or Moneybookers don’t qualify.

LC International Limited runs both Coral and Ladbrokes, so holding new accounts at both may not be possible. Our best casino apps for slots page compares the wider slot lobbies.

18+. Every casino game has a built-in house edge, so over time you should expect to lose what you stake. Set a budget before you play and stop when it’s gone: safer gambling tools and support. Free, confidential help: National Gambling Helpline 0808 8020 133.
