This online casino software company started off intending to shake up the iGaming industry by creating content that’s different from what other developers have flooded the market with. Though the vision was huge, the company set out in a small studio somewhere in Stockholm, Sweden.
Backed by a team of professionals across different fields and a dedicated management, they have grown the brand to become a force to be reckoned with in terms of being an independent, boutique casino software developer. Over a period of thirteen years, a lot has changed about the company. It has grown from a modest team of ten to over 80 across different fields of online casino title makers. They’ve been able to extend the horizon to Malta, where they operate an office.
Thunderkick is a two-time recipient of the Videslots Awards, the first in 2017 and the second in 2019. That of 2017 was a dual award in favor of Frog Grog, getting recognized for the Best Low Volatility Game of the Year. The brand would receive the Best Mobile Game of the Year award in 2019 in favor of Flame Buster.
Before those recognitions, it had received the Best New Slots Provider award at the CasinoMeister Awards in 2018. A year before, it received the 2017 EGR B2B Awards for Innovation in RNG Casino Software. The last award was in 2021, when it went home with the Slot Provider of the Year award at the International Gaming Awards. It received a couple of nominations in the coming years, including Game Design & Art Direction at CasinoBeats Game Developer Awards in 2024.
At the core of the company’s philosophy is streamlining the online casino play process and making it easier for users to navigate. In light of current realities, most of the Thunderkick slots have been optimized to work on mobile devices. The company also prioritizes investments in creating HTML5-focused slots, allowing for these to be played on both mobile and desktop devices.
The strong mobile optimization efforts not only make the few titles in the library stand out, but also fetch Thunderkick Casinos industry recognition. From winning the Best Mobile Game of the Year in 2017 to being recognized as the Best in Innovation in Mobile in 2020, the company has stood out and stands tall in the iGaming industry.
This boutique online casino software provider ranks as one of the game developers with titles geared towards improving players' experience across the board.

Still in commitment to the goal of leading the industry with innovation, they have been able to introduce new mechanics different from what exists. On top of this are the high volatility free spins and cascading avalanche reels. It takes up with a different reel structure, one that's gridless. This removes the paylines and reels, especially on specific titles, one of which is Fruit Wrap. Players can also get double offers, such as cascading reels and multiplying wins in one fell swoop.
