Eternal Duel bonus features

There are some entertaining bonus features in this Greek themed slot:

• DuelReels

  When a VS symbol lands as part of a winning combination, it expands to form a DuelReel, which turns wild and applies a multiplier to the connected win. The multiplier can range from x2 up to x100, and if multiple DuelReels appear in the same spin, their multipliers combine, affecting the total win.




• FS DuelReels

  Landing three or more scatter symbols triggers FS DuelReels, awarding a certain number of free spins per symbol, typically ranging between 2 and 10. These DuelReels can duel against one another to determine the final spin count. Also, some FS symbols can appear with an Upgrade icon, which can elevate the round to a higher-tier bonus.




• Hades Havoc

  Hades Havoc is triggered by three FS DuelReels and begins with at least six free spins. Each reel features top and bottom Reel Multipliers, ranging from x2 to x50, which are applied during DuelReels. Relic and Cyclops symbols landing on the reels increase these multipliers progressively - symbols in the top two rows affect the top multiplier, those in the bottom two rows affect the bottom multiplier, and symbols in the middle row affect both. Multipliers can reach a maximum of x999.

  Wilds count as x1 but benefit from the Reel Multipliers during wins.




• Zeus Fury

  Landing four FS DuelReels triggers Zeus Fury with a minimum of eight free spins. This round uses the same multiplier mechanics as Hades Havoc but adds multipliers to wild symbols depending on their row position: top values for the upper rows, bottom values for the lower rows, or both combined in the middle row. Each FS DuelReel that lands during this round adds 2-10 extra spins.




• Eternal Destruction

  The highest-tier bonus, Eternal Destruction, is triggered by five FS DuelReels and begins with at least ten free spins. In addition to the multipliers and extra spins from Zeus Fury, every spin is guaranteed to include at least one wild, one Relic or Cyclops symbol, and one DuelReel.

Eternal Duel Slot Summary

The base game provides small wins while setting up the main features, and DuelReels, FS DuelReels, the scatter symbol, wild symbols, and multipliers interact to build potential larger payouts.

Overall, the bonus rounds in Eternal Duel slot are layered, meaning that FS DuelReels can upgrade standard spins into Zeus Fury and then into Eternal Destruction, and each level retains the multipliers, wilds, and any accumulated extra spins from the previous stage.

Compared to other Hacksaw Gaming slots, like Wanted Dead or a Wild, Eternal Duel continues the trend of feature-led mechanics with progressive bonus rounds, but it introduces a multi-tiered upgrade path from FS DuelReels to Zeus Fury and Eternal Destruction - making it structurally more complex than single-feature slots.
