Thunderkick releases around seven slot games per year, averaging one every two months.  The next game due for release is Raven's Eye on June 19th.
This is significantly less than other slot providers, however, Thunderkick has fewer resources than powerhouses like NetEnt and Microgaming.
Although you have to wait a little longer for new games, they're certainly worth it when they finally arrive. It's clear that Thunderkick prioritises quality over quantity and doesn't launch any products that fall below its high-standards.
