13th Trial Hercules Abyssways: Slot Overview

Hercules, the powerhouse of Greek mythology, is best known for completing 12 brutally demanding labours as punishment after the tragic killing of his wife and children. To be fair to him, the crime was committed while he was driven insane by Hera, who resented Hercules as proof of Zeus’ unfaithfulness. What we’re looking at here is the idea of a 13th labour, something software provider Play’n GO teases in 13th Trial Hercules Abyssways, an online slot that treads very similar ground to the Hannibal Barca-inspired title Scourge of Rome.

Without claiming certainty, it’s easy to imagine 13th Trial Hercules Abyssways being set on or around Mt Olympus, the legendary home of the Olympian gods and their lavish palaces of gold and marble. The real Mt Olympus lies between Macedonia and Thessaly and stands as Greece’s tallest mountain. Make the climb yourself and you won’t see quite what Play’n GO has painted here—towering peaks crowned with grand structures and waterfalls spilling down the cliffs—creating a heavenly vibe that sounds nearly as impressive as it appears.

The challenge unfolds on a 6×4 gaming area using a ways-to-win mechanic, producing 4,096 possible winning combinations. During free spins, the reels can grow, meaning up to 46,656 ways to win can be reached in that stage. A touch calmer than Scourge, 13th Trial Hercules Abyssways is rated 7 out of 10, or medium-high volatile, and—typical for Play’n GO—comes with five RTP options, with 96.2% as the headline return. Bets run from 10c to $/€100 per paid spin.

Sharp-edged Greek-style 10-A card symbols return 1x-1.4x the bet for 6 of a kind. Higher-value icons include helms, vases, grapes, Zeus statues, Hera statues, and Hercules himself, paying 4x-12x the bet for 6 OAK. Wilds—both the 1×1 version and the expanded wild—replace any standard paying symbol, but they show up only in the base game.

13th Trial Hercules Abyssways: Slot Features

The Will of Zeus feature can occur in the base game, while free spins—when triggered naturally—include a reel growth/shrink mechanic called Hera’s Wrath – Abyssways, along with a Pegasus modifier.

Will of Zeus

The wild may land anywhere except the leftmost reel, and when two or more wilds appear, the Will of Zeus features triggers. In this feature, any wild that is part of a win has a chance of transforming into a full reel expanding wild. The odds depend on how many wilds are on the grid: with two wilds, each has a 50% chance; with three wilds, each has a 33% chance; and with four wilds, each has a 25% chance.

Free Spins

Hitting 3, 4, 5, or 6 scatters grants 10, 15, 20, or 25 free spins, respectively. In the free spins round, Hercules symbols are sticky. On top of that, they pay even if there are reel gaps between them, and Hercules wins can begin from any reel. At the start of every free spin, a random number of symbols at the bottom of the reels become burned, then once the spin ends, all burned symbols fall from the grid, shrinking the reel set. Between each free spin, a new full row of symbols is added to the top of the grid, expanding the reels again.

Pegasus symbols can land during free spins. When a Pegasus symbol appears, all Hercules symbols move one step upward before the burned positions drop away. If there are fewer than 3 Hercules symbols visible, Pegasus increases the count up to 3. Every scatter that lands during the feature adds +1 free spin up to a maximum of 50 free spins.

13th Trial Hercules Abyssways Slot Verdict

Saying 13th Trial Hercules Abyssways walks in Scourge of Rome’s footsteps isn’t an overstatement. The two games are extremely close in both flow and feature set, bringing the same strengths and weaknesses along with them. The base game is decent but can feel a little sluggish, although Will of Zeus can spice things up by upgrading wilds into something more impactful and potentially rewarding. In theory, as many as 4 expanding wilds can appear on a 4,096-way layout, so it might come together nicely. And, as with Scourge of Rome, the production values are strong—though Greek mythology, interesting as it is, shows up far more often in slots, making it less novel than a theme like the Carthaginian march into Italy.

Once free spins begin, the feature’s specific mechanics can make the bonus feel like a genuine emotional ride. One moment you’re celebrating if the setup clicks, the next you’re groaning as Abyssways burns chunks of the reels away. Hercules symbols do stick in free spins, yet they also shift downward as new rows are added at the top and burned symbols are removed. When Hercules symbols get burned, they drop off the bottom too, so they may not feel as reliably “sticky” as some players might hope. Building up a healthy number of Hercules symbols could end up being a labour in itself, and it doesn’t help that wilds never appear in free spins, meaning Will of Zeus and the full-reel expanding wilds are completely absent from the bonus.

If Scourge of Rome’s max win made you raise an eyebrow, then 13th Trial Hercules Abyssways’ huge 60,000x may have doubtful (or realistic) players shaking their heads again. Even so, it’s a massive target for those willing to chase it while enduring the swings 13th Trial Hercules Abyssways can dish out—though the overall formula hasn’t really moved forward, if at all, from what came before.
