Introduction
Step inside a chilly snow-covered Scandinavian scene and join your Viking companion as you attempt to decipher ancient runes and uncover hidden treasures. So grab your cold weather clothes and let’s dive right in…
Theme, Graphics & Soundtrack
True Lab free slots are renowned for offering high-quality playing experiences, and Viking Runes is certainly no exception to that. You will immediately find yourself standing in front of a hammer-wielding Viking guarding stacks of runes. As well as standing in an intimidating pose, he’s breathing heavily thanks to some excellent animations. Be warned that he also grunts when winning clusters land.
The straightforward beat-heavy soundtrack reflects the theme well, and the stone-clunking effects that play when the reels are in motion further enhance the in-play ambiance. The smaller table to the right of the reels will display your last six winning combinations, which is a great extra touch - particularly when the paytable is as extensive as it is here.
