Gameplay and Features
The Eternal Duel online slot includes the innovative Duel symbols that transform into Wild DuelReels™, the strategic FS symbols that manage free spins and bonus upgrades, and a generous multiplier system that significantly amplifies payouts. All of these are neatly explained below:
- Duel Symbols: Landing Duel symbols triggers a showdown between two distinct values. These symbols expand and become Wild DuelReels™, revealing two unique multipliers. The winning multiplier is then applied to any active win, boosting immediate payout potential within the game.
- FS Symbols: When FS symbols appear, they initiate a duel between different spin amounts. All winning spin values are accumulated for the total spins awarded. These symbols also offer possible upgrades that can elevate the bonus game to either Bonus 2 or the highly anticipated Hidden Epic Bonus™.
- Bonus Games: Eternal Duel features two distinct godly bonus games, complemented by the elusive Hidden Epic Bonus™. These rounds are primarily triggered by landing three or more FS Scatter symbols, providing concentrated opportunities for increased payouts through advanced mechanics and higher multiplier potential.
Eternal Duel’s x15,000 maximum payout is achievable within the bonus games when Wild DuelReels™ deliver considerable multipliers. These combine with the accumulation of spins from FS symbols and potential upgrades to Bonus 2 or Epic, facilitating sustained high-value win potential.
