Thunderkick slots range from the fixed paylines of 1429 Uncharted Seas to Fruit Warp, where there are no paylines at all. Esqueleto Explosivo, Pink Elephants and Midas Golden Touch each have their own slot series, too. Here we compare a selection of those games, explain the published RTP figures and bring together demos and UK casino options.
UK casino sites to play Thunderkick
The reviews below compare casinos in the UK where you can play Thunderkick games. A Thunderkick logo in a lobby does not mean the casino carries every release: look for the full game title before choosing an account for it.

Thunderkick slots: free demos and mobile play
The demos use virtual credits. There are no real-money stakes or cash prizes. 18+.

For new players, demo play makes unfamiliar slot formats easier to follow: you can see the gameplay behind a feature description. You can play for free and open the paytable to compare what the rules say with what appears on screen. Our wider free demo slots directory also lets you browse other developers.
Try opening the paytable on your phone. If the text is too small or the stake buttons feel cramped, that matters more than how the reels look. A demo win tells you nothing about your next paid spin. Availability also varies by country and casino.
Five Thunderkick slots and their bonus features
Esqueleto Explosivo 2 – Reborn
Exploding wilds drive the action in Esqueleto Explosivo 2 – Reborn. The Explosivo Wilds remove symbols, while Dropping Symbols and Mucho Multipliers are part of the game’s feature set. The skeletal mariachi theme carries over into a slot with five reels and 99 payways.
The main bonus game awards free spins. Thunderkick’s global page also advertises Feature Buy; the UK restriction on buying direct access to a bonus is covered in the questions below.
Pink Elephants 2 – Reborn
Pink Elephants 2 – Reborn opens out to six reels and 4,096 connecting payways. A Mystery Scatter is involved in unlocking the bonus, which combines free spins with symbol transformations and retriggers.
Thunderkick rates this edition as high volatility. The 4,096 ways to win refer to connecting combinations across the reels; the FAQ below explains why that is different from win frequency.
Midas Golden Touch – Reborn
The gold-covered palace in Midas Golden Touch – Reborn contains a more compact setup: five reels and 15 paylines. Multiplier wilds and a bonus with sticky wins are its main features.
Fruit Warp
Fruit Warp takes the payline count out of the comparison altogether. Thunderkick lists paylines as “not applicable” and describes a Fruit Mode activated by five or more fruits, with a dynamic multiplier.
1429 Uncharted Seas
1429 Uncharted Seas uses five reels and 25 paylines, with expanding wilds and free spins. The maritime theme comes with a low-volatility rating on Thunderkick’s own game page.
Its published 98.6% RTP is the highest among these five examples. The table below puts that figure beside the other games’ returns and volatility ratings.
About Thunderkick
Thunderkick began in Stockholm in 2012. The Swedish studio remains independent and keeps the design and development of its online slot games in-house.
Thunderkick creates the software; the casino where you play manages your account. Our guide to casino game providers explains how studios, operators and the platforms connecting them fit together.
Thunderkick’s UK Gambling Commission licences
There are two relevant British register entries. Thunderkick AB holds active remote gambling software licence 040165-R-320747-006, under account 40165. Thunderkick Malta Limited, account 41752, holds active remote casino licence 041752-R-321094-007.
These entries identify Thunderkick’s licensed businesses. For the site holding your balance, check the casino operator and its web address separately in the register.
Thunderkick RTP, volatility and max win
Thunderkick publishes the following figures on the official game pages linked above. They refer to the named editions; check the information inside the game you actually open at a casino.
| Game edition | Published RTP | Published volatility |
|---|---|---|
| Esqueleto Explosivo 2 – Reborn | 96.13% | Medium |
| Pink Elephants 2 – Reborn | 96.13% | High |
| Midas Golden Touch – Reborn | 96.17% | High |
| Fruit Warp | 97.00% | Medium |
| 1429 Uncharted Seas | 98.60% | Low |
Two games here share a 96.13% RTP but have different volatility ratings. RTP describes the theoretical return across a very large amount of play; volatility concerns the spread of results. Neither figure tells you what the next spin will pay or when free spins will arrive.
For slots like Midas and Pink Elephants, look up the max win in that edition’s paytable. It usually appears as a multiple of your stake and sets the payout ceiling for the slot game. That headline win potential gives no indication of your chance of reaching it.
Set a spending limit based on what you can afford to lose, rather than on a return percentage. Mr Win’s responsible gambling guide covers limits, breaks and support.
Finding Thunderkick slots at online casinos
Typing “Midas” into a casino search is only a starting point. Midas Golden Touch – Reborn and Midas Golden Touch 3 are separate releases, so the full name on the game tile is the useful detail.
A casino’s free-spins offer is also separate from a slot’s built-in free-spins round. An offer naming Pink Elephants 2 may not cover Pink Elephants 2 – Reborn. A welcome offer for new customers may limit play to selected games. Check whether winnings from free spins are paid as cash or bonus funds, what wagering requirement and maximum stake apply, and when the spins expire. A larger bonus amount is not enough to compare two offers without those conditions.

Thunderkick questions
Is Thunderkick part of NetEnt or Evolution?
Thunderkick describes itself as an independent studio based in Stockholm. It is a separate developer; a casino listing Thunderkick alongside NetEnt is showing games from different studios.
Why is Feature Buy missing from a UK version?
Some global Thunderkick pages advertise a paid shortcut into the bonus. The Gambling Commission’s warning records that operators removed feature buy-ins following its intervention. A feature on the international product page is therefore not a promise that it will appear at a UK casino.
Does 4,096 ways mean Pink Elephants 2 – Reborn pays more often?
The ways count alone cannot tell you how often a game pays. It describes the combinations available under its rules. The frequency and size of wins depend on the game’s maths, so it is not a reliable basis for comparing it with a 15-payline slot.
