- Scatter (wood symbol Yggdrasil): appears only on reels 2, 3, and 4. 3 Scatters activate 10 free spins.
- Free spins: during the bonus round on the reels, more WildEnergy symbols appear, which significantly increases the chances of chains of respins and big wins.
- Golden Bet: optional feature (for an additional fee), guaranteeing at least one Wild appears on each spin.
- Buy Bonus: the ability to purchase free spins directly (not available in all jurisdictions).
Risk-game is absent.
