Slot Summary

Thor's hammer supplies the theme and the mechanical logic for Mjolnir, a refreshed JDB elimination slot where completed wins clear space for more symbols. Lightning Wild guarantees a win when it appears, while Thunder Strike adds further wilds. The free-spins round raises its bonus multiplier after each elimination, giving the cascading sequence greater importance than the conventional 243-ways format alone suggests.
MechanicsCascades raise the free-spins multiplier to 8x

How It Plays

Combinations form across 243 ways, then winning symbols disappear. New symbols occupy the available positions, so one paid result can lead directly into another.

The base loop gains interruptions from Lightning Wild and Thunder Strike. One guarantees a winning result, while the other places additional wilds into the active symbol field.

Theme & Atmosphere

Mjolnir draws on Norse mythology, placing Thor and his famous hammer at the center of its Fantasy and Viking subject matter.

Thunder and lightning connect the Medieval presentation to play rather than serving as decoration alone, since both accompany named wild effects and symbol elimination.

Features & Win Potential

Avalanche and Cascading describe the same central sequence: winning symbols clear, replacements arrive, and the round continues whenever another valid combination forms.

The Wild Symbol has two distinct interventions. Lightning Wild guarantees a win, while Thunder Strike contributes additional wilds after the symbols have settled.

Bonus & Free Spins

Free Spins retain the elimination system but attach a rising Free Spins Multiplier, increasing its value whenever another elimination occurs during the same sequence.

The Bonus Game therefore rewards consecutive Cascading results differently from the base round, with the multiplier able to reach 8x before that sequence closes.
