Bonus Features Deep Dive
1. Tumbling Reels & The Soulforge Meter
- Tumbling Reels: Standard cluster-pay mechanic.
- The Soulforge Meter: This is the core progression system. Each symbol in a winning cluster charges the meter.
- At 25%: 1-2 random symbols are transformed into a matching high-paying symbol.
- At 50%: A Valkyrie Wild is added to a random position on the grid.
- At 100% - Einherjar's Charge: Triggers a massive cascade where all Low-Paying symbols are removed, and the grid is flooded with new symbols, guaranteeing a win.
2. Ragnarok Free Spins
- Trigger: Land 4, 5, 6, or 7 Bifröst scatters to award 7, 8, 10, or 12 free spins.
Special Rules - The Soulforge Meter is active but has no stages; it now fuels a global multiplier that starts at 1x and increases with every tumble.
- All Valkyrie Wilds that land become Immortal (sticky) for the remainder of the round.
- The Soulforge Meter filling now adds +1 extra free spin instead of triggering its stages.
3. Odin's Gaze Random Feature
- This can occur on any spin. Odin's ravens, Huginn and Muninn, fly across the grid, selecting two different low-paying symbol types and transforming all instances of them into a single, randomly chosen high-paying symbol.
