Thunderkick Thunderkick

Overview

Thunderkick is a slot development studio founded in 2012 in Stockholm, Sweden, by developers who came from NetEnt. It operates independently with no parent company or outside investors, and more than 80 employees build every game in-house. It makes only slots, with no table games.

Thunderkick’s philosophy is “quality over quantity.” Unlike other providers that pour out more than ten games a month, it releases only about one a month, putting care into its distinctive art style, humor, and music. It describes itself as making “awesome content that no one can simply pass by.” It has released more than 85 slots so far.

License

It holds licenses from the UK Gambling Commission (UKGC), Malta Gaming Authority (MGA), the Swedish Gambling Authority (Spelinspektionen), and Romania’s ONJN, and its random number generator (RNG) is certified by QUINEL.

Esqueleto Explosivo Series

Thunderkick’s most successful series, themed around Mexico’s “Day of the Dead.” Its signature feature is a structure where skull symbols burst and chain wins keep rolling.

Mucho Multiplier

This is the signature feature of the series. Every time you win in the base game, the multiplier doubles (1→2→4→8…). In the third game, this multiplier grew as high as 1,024x.

Explosivo Wild

In the third game, a regular wild or an “Explosive Wild” is left where a skull bursts. Explosive Wilds clear the surrounding 3×3 area at once, keeping the chain going. In the free spins, triggered by 3 scatters, you get an extra spin every time you collect 3 Explosive Wilds.

Pink Elephants Series

A psychedelic-themed series that began in November 2017. With its dreamy art style and music, it’s considered the work that best shows Thunderkick’s personality.

Pink Elephants Trinity, the third game, released on November 12, 2025, has a max win of 14,000x. In the base game, a “Mystery Lightning” can strike at any time and scatter up to 5 peanut scatters, and collecting 144 peanuts reaches the final bonus stage, “Pink Triangle Apex.” The bonus is split into 6 stages, and during the bonus a seventh reel appears in the middle, expanding the game up to 16,384 ways. There are 4 ante bet options that can raise your chance of entering the bonus by up to 144x.

Other signature slots

Recent games often include expanding wilds, sticky wilds, and bonus buy.

Founding and Operations

Thunderkick is a studio founded in 2012 by developers from NetEnt with the idea of “innovation and quality first.” It operates independently with no outside investors or parent company, and makes only slots. Everything from planning to art to math is done in-house, and it keeps a slow pace of about one release a month.

Signature game stats

“1429 Uncharted Seas” has an RTP of 98.5%, often cited as one of the highest theoretical return rates among online slots. In exchange, its max win is a low 670x, so it’s a game for playing a long time rather than chasing one big hit. It’s a good example of how RTP, max win, and volatility are linked.

Features of Thunderkick games

If fellow Swedish provider Quickspin leans toward a fairy-tale style and Nolimit City toward dark black humor, Thunderkick stands out for its bright, quirky personality.
