Thunderkick casinos are online casinos that carry slots from Thunderkick, an independent studio founded in Stockholm in 2012. Thunderkick is known for unusual art, short game names and a mix of gentle and very swingy slots, from 1429 Uncharted Seas (98.6% RTP) to Pink Elephants (high volatility, up to 8,200x). This page explains who the studio is, which licences it holds, the RTP, volatility and maximum win of seven notable games from Thunderkick’s own game pages, and how to check the version a casino runs.
We checked all figures on thunderkick.com on 8 October 2026. We did not find Thunderkick on the public pages of the partner casinos we list elsewhere, so this page has no casino list. We would rather send you to the studio’s facts than to a casino that may not carry its games.
Who Thunderkick is today
Thunderkick was founded in Stockholm in 2012 and describes itself as independent and privately held. It operates through two companies: Thunderkick AB in Sweden and Thunderkick Malta Ltd. Both are licensed and regulated in Great Britain by the Gambling Commission, under account numbers 40165 and 41752. The footer of its site also shows the Malta Gaming Authority, Spelinspektionen (Sweden’s regulator) and the AGCO in Ontario.

What Thunderkick is known for
Thunderkick’s games look different from most slots. The studio uses playful, often humorous art and themes such as a skeleton mariachi band on the Day of the Dead (Esqueleto Explosivo), Mexican wrestling (Luchadora) and a pink dream world (Pink Elephants). Many of its classic games are low volatility with modest top wins, which suits long, relaxed sessions. More recent releases, starting with Pink Elephants and the Esqueleto Explosivo sequels, push the maximum win and volatility much higher.
The studio is also known for 1429 Uncharted Seas, one of the highest-RTP slots from a regulated studio at 98.6% on its game page. High RTP plus low volatility makes it a frequent recommendation for players who want their budget to last, though bonus terms sometimes exclude it for that reason.
Notable Thunderkick games: RTP, volatility and max exposure
The table shows the figures printed on each game’s page at thunderkick.com. Thunderkick calls the maximum win “max exposure”: the largest possible win in a round, as a multiple of the stake.
| Game | RTP (Thunderkick) | Volatility | Max exposure | Main feature |
|---|---|---|---|---|
| 1429 Uncharted Seas | 98.6% | Low | 670x | Expanding wild, free spins, 25 lines |
| Esqueleto Explosivo | 96.0% | Low | 700x | Dropping symbols, Mucho Multipliers, Explosivo Wild, 17 lines |
| Esqueleto Explosivo 2 | 96.13% | Medium | 5,000x | 99 pay ways, Explosivo Wilds, Mucho Multipliers, feature buy |
| Pink Elephants | 96.1% | High | 8,200x | Mystery scatter; free spins with symbol transformation |
| Luchadora | 96.2% | Medium | 1,995x | Wrestler Wilds, Underdog, Lucha Smackdown, free spins |
| The Turning Totems | 96.1% | Low | 998.6x | Thunder Reels, Sleeping Wilds, respin, bonus game |
| Magicious | 96.0% | Low | 1,400x | Expanding wild with respin, wins both ways, 10 lines |
1429 Uncharted Seas
An ocean-exploration slot with an expanding wild and a free-spins bonus on 25 paylines. Thunderkick lists 98.6% RTP, low volatility and a 670x maximum. It is a game for long sessions with small, frequent wins rather than a chance at a large prize.
Esqueleto Explosivo and its sequels
The original Esqueleto Explosivo (96.0%, low volatility, 700x) uses Explosivo Wilds that blow up symbols, dropping symbols and Mucho Multipliers that rise as wins continue. Esqueleto Explosivo 2 raises the stakes: medium volatility and a 5,000x max exposure at 96.13%. Later games in the series go higher again, and some carry lower RTP settings, so check each one separately.
Pink Elephants
The swingiest game in our table. Thunderkick lists 96.1% RTP, high volatility and an 8,200x max exposure. A mystery scatter and a free-spins bonus with symbol transformation and retriggers do most of the work.
Luchadora, The Turning Totems and Magicious
These three were featured on the old version of this page and are still on Thunderkick’s site. Luchadora (96.2%, medium, 1,995x) is a Mexican wrestling slot with Wrestler Wilds, an Underdog feature, Lucha Smackdown and free spins. The Turning Totems (96.1%, low, 998.6x) has Thunder Reels, Sleeping Wilds and a respin. Magicious (96.0%, low, 1,400x) is a magic-show slot with an expanding wild and respin on ten lines that pay both ways.
How to check a Thunderkick game’s RTP at a casino
- Open the game at the casino and open the paytable or information menu.
- Find the RTP line in the rules. Compare it with the figure on Thunderkick’s own game page (our table).
- If the numbers differ, the casino runs a different configuration, or the game is a newer version with its own maths.
- Check the volatility and max exposure in the same place, because they decide how a session feels more than a small RTP gap does.
- Do not play at a casino that hides the RTP.
A worked example shows why RTP matters on long sessions. Over 2,000 spins at EUR 0.20 (EUR 400 staked), 1429 Uncharted Seas at 98.6% has a theoretical cost of EUR 5.60, while a 96.0% game such as Esqueleto Explosivo costs EUR 16.00 in theory. Neither figure predicts your result; both show the price of play over time.
Choosing a Thunderkick slot for your session
| If you want | Try | Why (Thunderkick figures) |
|---|---|---|
| Your budget to last | 1429 Uncharted Seas | 98.6% RTP, low volatility, 670x cap |
| A light, classic feel | Esqueleto Explosivo, Magicious, The Turning Totems | Low volatility, 96.0% to 96.1% |
| Something in between | Luchadora, Esqueleto Explosivo 2 | Medium volatility, up to 1,995x and 5,000x |
| A shot at a big win | Pink Elephants | High volatility, up to 8,200x |
Low-volatility games pay small amounts often, so they suit small stakes and long sessions. High-volatility games can go hundreds of spins without a notable win; if you play Pink Elephants, lower the stake so your budget covers enough spins, and keep a firm loss limit.
Thunderkick bonuses
When you find Thunderkick games at a casino, read the bonus terms before using bonus money on them. High-RTP, low-volatility games such as 1429 Uncharted Seas are often excluded from wagering or counted at a reduced rate, because they make wagering easier to complete. Free spins on a Thunderkick game, where offered, should state the value per spin and any cap on winnings. Our guides to welcome bonuses and free spins bonuses explain the common terms.
Thunderkick security and fairness
Thunderkick games are certified for each regulated market where they are supplied, under its UK Gambling Commission licences and its other approvals. Certification checks that results are random and that the game returns what its rules say. It does not vouch for the casino. Before you deposit, check the casino’s own licence on its regulator’s register; our safe casinos guide shows how.
