Thunderkick Launches Bjorn with an 8×8 Battle Grid
Thunderkick's Bjorn is live with an 8x8 cluster grid, avalanches, Loot and Abilities, a 5,000x max win and a 94.22% RTP.

Thunderkick released Bjorn on October 9, 2026, and announced it as live the same day. The slot sets a Norse guardian against waves of Draugr and Trolls on an 8×8 grid, with cluster pays that start at 5 matching symbols.
Wins come from avalanches, and three systems build the hero’s strength as a fight goes on: Loot, Abilities and a Global Multiplier. The demo’s rules screen adds a Hero Hunt that starts when no winning clusters remain, sending the hero after every Draugr on the board. Thunderkick describes a Bonus Game with free spins and retriggers.
The numbers Thunderkick lists are an RTP of 94.22%, Very High volatility and a max win of 5,000x. That RTP is lower than the 96% many new releases quote, which is worth checking against the version at your casino. Reviews mention a Bet+ ante option, but Thunderkick’s page doesn’t give its prices.
The setting is a Norse dark fantasy: a warrior chosen by the gods defends an ancient power, and the middle of the board is left empty as a platform for him to stand on.
