About Stormborn

Released on September 11, 2025, Stormborn is a Norse mythology slot from Hacksaw Gaming — according to specialist reviewers, it is "perhaps the finest Nordic-themed slot created by the studio." Format 5x4 / 14 paylines, RTP 96.27%, max 15,000x, high volatility.

The visual world depicts a frozen Scandinavian landscape, glowing Viking runes, Thor's hammer Mjolnir in the background, and an icy blue-electric gold palette. The signature mechanic is Thunder Respins, triggered by collecting coins — collected coins stay locked on the grid while the other reels respin.

5 distinct free spin modes are accessible via Bonus Choice (the player picks between the different modes), including the hidden Blessing of the Bifrost (5 scatters, epic mode). The Mjolnir hammer applies multipliers to symbols during the bonus rounds. Reduced RTP versions go as low as 86.23% — check in-game.
