Eternal Duel Slot (Hacksaw Gaming)

The Eternal Duel slot comes with 5 reels, 5 rows and 19 fixed paylines. Landing 3 or more matching symbols on adjacent reels, starting on the leftmost reel and across any of the 19 paylines will constitute a winning combination. Just the highest win per payline will be awarded.

As with other Hacksaw slots, the minimum bet per spin is 10p: the maximum is £5 in the UK (or £2 if you’re under 25). Use the up and down arrows to change your bet. Located outside the UK? You can use Turbo/Super Turbo modes and Autoplay (both prohibited in the UK).

The Eternal Duel RTP rate is 96.42%, which is higher than the slot/Hacksaw average. You may come across 94.24% and 92.39% RTP versions so check the Paytable.

Medium to high volatility, a winning combination will land every 1 in 3.26 spins as the hit frequency rate is 30.61%. Lastly, Eternal Duel comes with 15,000 x bet max wins: this can be won in the base game and various bonus features.

With a Greek mythology theme, the Eternal Duel slot is about 2 brothers, 2 realms and 1 destiny. In this godly battle, Zeus (god of sky, thunder, lightning and justice and the king of the Olympian gods) and Hades (god of the Underworld) take on the DuelReels.

The first thing that sprung to mind was Pragmatic Play’s Zeus vs Hades – Gods of War. This rendition from Hacksaw benefits from stunning graphics where you’ll see the 2 realms collide: With Zeus floating majestically, Hades is equally ready for battle. The visuals are realistic and beautifully crafted.

This is complimented by the emotive soundtrack that sounds like it was produced by Hans Zimmer. All in all, it’s one of the most beautifully-designed games I’ve come across (over 15,000!).

On the reels, you’ll come across low-value A, K, Q, J and 10 royals (all paying up to 1 x your total bet). The higher-value symbols include goblets, skulls, Cerberus (3-headed dog), Hades and Zeus: both Hades and Zeus are the best-paying symbols, awarding 15 x your total bet for 5 in combination.

Eternal Duel comes with a Wild symbol that substitutes for all paying symbols: 5 wilds across a payline will pay 20 x your total bet. Other special symbols include non-paying Dead symbols, a VS symbol and an FS Scatter.

Eternal Duel Mobile

Eternal Duel can be played on desktop, mobile and tablet devices. Using HTML5 technology, you will play in Portrait Mode when playing on an iOS or Android smartphone. To experience this game’s beauty, I recommend a PC or laptop. It’s mesmerising.

The Eternal Duel slot focuses on the DuelReels mechanic as well as 3 free spins modes with Reel Multipliers, Wilds that take on Reel Multiplier values and guaranteed special symbols for enhancing winning potential.

DuelReels

When a VS symbol lands on the reels, the VS symbol expands into a DuelReel is part of a winning combination (once expanded). Covering the whole reel, a Duel between Zeus and Hades is initiated. Each DuelReel has a multiplier from 2x to 100x with the winning duellist applying his multiplier on that DuelReel and all wins connected to it. If more than 1 DuelReel is part of the same winning combination, their winning multipliers are added together and then applied.

FS DuelReels

When 3 or more FS Scatters land on the reels, each FS Scatter expands into an FS DuelReel. Each FS DuelReel has 2 free spin values (2-10) that duel against each other. The winning free spin value of each FS DuelReel will be added together to determine how many free spins you get.

When you trigger a feature, there is a chance that a FS DuelReel will contain an Upgrade: this upgrades you to the next feature.

• 3 FS DuelReels + 1 Upgrade = Zeus Fury free spins
• 3 FS DuelReels + 2 Upgrades = Eternal Destruction free spins
• 4 FS DuelReels + 1 Upgrade = Eternal Destruction free spins

Free Spins features

Eternal Duel comes with 3 free spins features, with upgraded mechanics from the base game. Below are all the details:

Hades Havoc

Triggered by 3 FS DuelReels symbols, you get 6 free spins. A Reel Multiplier will appear at the top and bottom of each reel. Each Reel Multiplier begins with a random Additive Multiplier value of 2x to 50x. When DuelReels are triggered, the dueling multipliers come from the top and bottom Reel Multipliers on the reel where the VS symbols landed.

The Reel Multipliers progressively increase when Relic and Cyclops symbols land on the reels. Symbols land on the top 2 rows affect the top Reel Multipliers with symbols landing on the bottom 2 rows affecting the bottom Reel Multipliers. Symbols appearing on the middle reel will affect both Reel Multipliers. Relic and Cyclops symbols activate from left to right, top to bottom:

• Relic symbols add their value to the top, bottom or both Reel Multipliers
• Epic Relic symbols add their value (1-50x) to all Reel Multipliers on the top, bottom or both
• Cyclops symbols multiply the top, bottom or both Reel Multipliers
• Epic Cyclops symbols multiply (2-10x) all top, bottom or both Reel Multipliers by their value.

With Relic and Cyclops symbols activating before DuelReels, Reel Multipliers can reach up to 999x.

When an FS DuelReels symbol lands, you’ll be rewarded with 2-10 extra free spins and the possibility of upgrading to the Zeus Fury feature (with 1 upgrade). If you land FS DuelReels with 2 upgrades, you’ll play the Eternal Destruction feature.

Zeus Fury

8 free spins awarded when you land 4 FS DuelReels symbols. It keeps the mechanics from the Hades Havoc feature. Additionally, Wild symbols receive a multiplier value from the Reel Multiplier on that reel:

• landing in the top 2 rows awards the top Reel Multiplier
• landing in the 2 bottom rows awards the bottom Reel Multiplier
• landing on the middle row awards the combined values of both Reel Multipliers

With Wilds counting as 1x, the multiplier value is applied to a win if Wild Multipliers are part of it. Multiple Wild Multipliers part of a win will see their values added together (from left to right).

If you land FS DuelReels symbols, you will get 2-10 extra free spins and a possible upgrade, to the Etenral Destruction feature.

Eternal Destruction

The Eternal Destruction feature is triggered by landing 5 FS DuelReels during a base game spin. With 10 free spins awarded, it keeps the mechanics of the Zeus Fury feature. Additionally, at least 1 Wild, 1 Relic or Cyclops and 1 DuelReel is guaranteed on each free spin. You cannot win extra free spins though.

Rating: 4/5

Eternal Duel is beautifully-designed slot that showcases the DuelReels mechanic in all its glory for up to 15,000 x bet max wins.

For starters, I must say the Eternal Duel slot is one of the best-looking games I’ve ever come across. Mesmerising and beautifully designed, the soundtrack as good as you’re going to get from a god-inspired slot game. 

The gameplay focuses on the DuelReels mechanic, which has been used plenty of times before by Hacksaw Gaming in games such as Duel at Dawn, Wanted Dead or a Wild and Bullets and Bounty. Multiple DuelReels is where the big win potential comes from no doubt.

With the 3 free spins features, you benefit from Reel Multipliers. Look out for Relic and Cyclops symbols as their values add or multiply Reel Multipliers. With the Epic versions, values apply to all Reel Multipliers. Remember that Reel Multipliers can reach 999x. To build up Reel Multipliers more effectively, you need symbols to land on the middle row.

In the Zeus Fury free spins, Wild symbols gain the multiplier value from the Reel Multiplier on that reel, depending on where it lands. The Eternal Destruction feature guarantees Wilds, Relic or Cyclops and DuelReel symbols for huge winning potential.

With 15,000 x bet max wins, Eternal Duel is an epic slot game where Zeus and Hades fight to the death. I love the graphics and soundtrack as well as the duelling nature throughout the base game and free spins modes: another top game from Hacksaw Gaming.

If you want slots with Zeus, Hades and other Greek gods, my guide to the best Greek mythology slots includes deities such as Medusa, Midas and Poseidon. Top games include Playtech’s Age of the Gods, Novomatic’s Lord of the Ocean and Light & Wonder’s Medusa Megaways.
