Eternal Duel Demo & Review

Eternal Duel review

Eternal Duel pits two divine brothers against each other on DuelReels. VS symbols that would join a win expand to cover their reel, and the winning duelist's multiplier applies to the whole reel. FS DuelReels work the same way, but for free spins: each one duels two spin values, and the winners are added to set your bonus length.

Bonus upgrades can also trigger here, moving you up to Zeus Fury or Eternal Destruction, depending on how many FS reels and upgrades land. The maximum is 15,000x. The FS duel adds something new to a familiar mechanic.
