Thunderkick

Thunderkick is a Stockholm-based game studio specializing in proprietary video slots for regulated online casino markets. The company has built a reputation for maintaining full creative and technical control over its production pipeline, operating independently across multiple European jurisdictions.

About

Company Background

Thunderkick AB, founded in 2012 by former NetEnt developers, was established with a focused ambition: to design and distribute slot games built entirely in-house. The company develops its own Remote Gaming Server (RGS), game engines, and distribution tools without outsourcing or sublicensing third-party content. This end-to-end control over production has allowed Thunderkick to maintain a consistent output while preserving its development autonomy.

Headquartered in Stockholm, the company also operates a licensed subsidiary in Malta, facilitating access to multiple regulated markets within the EU. Thunderkick employs approximately 80 staff members across both locations and remains privately held, and maintains a deliberately low public profile.

Product Offering

Thunderkick focuses exclusively on one product category: video slots. The studio does not produce table games, live casino titles, or sportsbook solutions. All games are developed in HTML5 and optimized for both desktop and mobile devices.

The studio releases a limited number of games each year, following a selective publishing strategy rather than volume-based output. All titles are proprietary—Thunderkick does not reskin existing games, license external IPs, or build white-label solutions. Instead, the company prioritizes creative independence and technical consistency.

As of 2025, the studio has released over 60 slot titles, each certified and localized for use in multiple languages and currencies.

Market Presence

Thunderkick holds B2B supplier licenses from:

  • The UK Gambling Commission (UKGC)

  • The Malta Gaming Authority (MGA)

Its games are also certified for use in various regulated markets, including Sweden, Germany, Romania, the Netherlands, and select non-European jurisdictions through distribution partnerships.

Thunderkick distributes its content through both direct integrations with licensed operators and via aggregation platforms. Notably, the company joined Relax Gaming’s Powered By program, significantly expanding its reach across global markets.

Its slots are currently available at a wide range of international online casinos, particularly those operating under European regulatory frameworks. The studio does not offer consumer-facing products, branded lobbies, or B2C platforms. Its model is focused entirely on B2B content supply.

While Europe remains its primary market, Thunderkick has also entered Canada and Latin America through selected aggregator channels and localized configurations.
