Eternal Duel has two wilds, scatter symbols, three bonus rounds, and a handful of buy-a-bonus mechanics. There’s a lot to consider, and it can be confusing at first, so I’ll be as straightforward as I can. Here’s what you need to know:

Eternal Duel is a fresh slot release to feature the VS Reel mechanics from Hacksaw Gaming. If you’ve followed their titles thus far, you’ll no doubt be familiar with this original engine, made famous in Wanted Dead or a Wild, Duel at Dawn, and Phoenix DuelReels. Of course, this time, it’s not sheriffs or outlaws duking it out – it’s deities.

Hacksaw Gaming’s Eternal Duel features DuelReels gameplay, something I’ve already seen and experienced in a handful of their previous releases. As in those games, this medium-risk release doesn’t really come alive until its bonus mechanics kick into gear. Once the Greek mythology-inspired game’s two chief deities, Hades and Zeus, start lacing up their gloves, the multipliers start to fly, and the game gets a new lease of life.
If you’ve played a DuelReels slot before, you’ll know all about that. If not, don’t worry. I’m going to walk you through the ins and outs of it all, but if you want a ringside seat to this duel, nip over to KingPrize, Crown Coins, Rolla, or any of our top, recommended SweepsKings casinos supporting Hacksaw games. In the meantime, let’s get started with a few pros and cons:
Pros
- Three free spin bonuses
- Decent wins are possible with the DuelReels mechanic
- Interesting take on a popular theme
- The RTP rate is on par with what we’d expect
- SC betting caps are modest
Cons
- Buy-a-bonus modes are overly costly
- Delivery rate isn’t great in buy-a-bonus modes

About Eternal Duel: Game Overview
Hacksaw Gaming’s Eternal Duel is a 5-reel, 19-line slot with a modest 96.42% RTP rate, medium-high volatility, and the popular DuelReels mechanic that introduces both chaos and random multipliers into gameplay.
Eternal Duel may be a DuelReels game, but it has more in common with Hand of Anubis or Stormborn in terms of theme. It tells the tale of Zeus and Hades’ rivalry. Two brothers – one ruling the Overworld, and the other, the Underworld. In true DuelReels fashion, the screen is divided into two, with Zeus’ domain up top, and Hades’ dominion located below.
As the game plays out, these two deities dish it out, providing wilds and multipliers across three thrilling bouts, with plenty of skirmishes in between.
Eternal Duel Slot Information
You might as well forget about the lowest-paying symbols in this game. The 10s, Jacks, Queens, Kings, and Aces all yield the same prizes – no joke. Three-of-a-kind, 10s are worth just as much as a trio of aces, which is stringy.
The more thematic elements in play include symbols representing golden chalices, skulls, and Cerberus, and they’re worth up to 10x. Zeus and Hades can dish out wins worth up to 15x apiece, while the conventional wild symbol is the best-paying symbol in this slot game.
So, how much can you win and what will it set you back? Bets can flex from 0.10 up to 50.00 here, which is quite modest. Prizes can hit a 15,000x max win. If you’re wondering how, it’s because there’s an abundance of multipliers to be had.
Eternal Duel Slot Features
Wild Symbols and Scatters
There is a pair of wild symbols. The first, a “W” icon, is the basic wild, substituting for standard paying symbols. The second is the VS symbol, and it is a wild multiplier. Scatters appear as FS symbols and can trigger one of the game’s trio of free game features.
DuelReels Mechanic
Triggered by the VS multiplier wild, this mechanic sees the symbol expand to cover an entire reel, but only if it can potentially result in a win. Once expanded, Hades and Zeus start to get it on. Each has a random multiplier (2x up to 100x) applied to it. One will inevitably be victorious in this little skirmish, applying their multiplier to the entire reel.
It’s worth noting that when I landed DuelReels on multiple reels (which was rare), I found that the multipliers are added together for a substantially larger reward.
Free Spins Modes
Eternal Duel comes with three free spin bonuses, and which one you land depends on how many FS scatters you land on a single spin. Three unlocks Level 1: Hades’ Havoc, while four or five scatters unlock Level 2: Zeus’ Fury, and Level 3: Eternal Destruction, respectively.
During any bonus, boxes appear above the top and bottom of the reels. These can contain multipliers or wilds based on the bonus game you trigger. A few new symbols will also pop up.
Relics can add between 1x and 50x multipliers to the top or bottom of the reels they land on. Cyclops can multiply existing reel values by 2x to 10x. Both symbols can also appear as Epic symbols. When this happens, they’ll boost the values on all reels simultaneously instead of just one. As great as this is, it’s just the start of your good fortune.
Hades’ Havoc
The first epic fight between Zeus and Hades takes place in the Underworld, which is triggered via three FS scatters. Here, you’ll get 6 free spins, with multipliers ranging from 2x up to 59x progressively increased by Relics or Cyclops symbols, as detailed above. It’s possible to land additional spins with new FS symbols.
Zeus’ Fury
Four FS scatters unlock this second contest, taking place in the Overworld. Here, Lightning Strikes can turn regular wilds into multipliers, a benefit they didn’t have in the base game. You’ll get 8 spins to kick things off. Apart from the fact that wilds can now land on the reels and inherit multipliers from the reels above or below them, the rest of the multiplier mechanics are the same as the Hades’ Havoc round.
Eternal Destruction
The ultimate feature is something Hacksaw calls a “Hidden Bonus”. It isn’t really – that’s nonsense. You just need five FS scatters to trigger it, which, admittedly, is a tall order. Once triggered, the Eternal Destruction round sees both gods clash one final time, with guaranteed wilds, Relics, Cyclops, and expanding VS symbol-triggered duels (with the necessary multipliers attached) available on every one of your 10 spins.
Feature Spins and Direct Buy Options
Hacksaw Gaming’s buy-a-bonus mechanic, the Feature Spins and Direct Buy purchasing options are present in the game, and I found them alive and well at KingPrize. It’s costly, too. The Bonus Hunt Feature Spins option costs 5x, and sees you 5 times more likely to trigger one of the three bonuses.
The Godly Feature Spins mode guarantees at least one VS symbol on each spin. You also have three Direct Buy options. You can trigger Hades’ Havoc, Zeus’ Fury, and Eternal Destruction directly for the unreasonable stipends of 80x, 300x, and 600x (or higher, depending on where you play).
Game Specs: RTP & Volatility
I found Eternal Duel to have an industry-standard RTP rate of 96.4%. In short, 0.96 SC of every 1 SC you play is put into a pot for all players to win, so sweepstakes casinos aren’t taking much from you. As the game also has medium-high volatility, don’t expect regular wins.
200 Spins Test of Eternal Duel
I decided to test this game at KingPrize, where the surplus of bonuses makes it a doddle to play Eternal Duel for free. You can find it at most sweepstakes casinos with Hacksaw games, though.
I gave it the usual 200-spin test to see if it measures up to other DuelReels games I’ve tried. It easily does.
My balance began at 75,000 GC, and my biggest win was 2,710.00 GC, ending with a balance of around 50,000 GC. Eternal Duel was kinder to me when playing with SC. Starting with 25 SC, I ended the day on 42 SC. It’s not a life-changing win, but when it mattered, the game delivered.
