Thunderkick is a Stockholm studio founded in 2012, operating independently with a deliberately small catalogue.

What they do:. A distinctive visual style and unconventional reel structures that avoid standard five-by-three layouts. Releases are infrequent but consistent in quality.

The ones that get played. Esqueleto Explosivo, Pink Elephants and Midas Golden Touch.

The upshot: Thunderkick games generally sit in the medium volatility band with straightforward mechanics, which makes them a practical choice for bonus wagering.
