The Abyssways engine inside 13th Trial Hercules Abyssways burns away the bottom row of symbols every free spin and rebuilds the grid from the top, and finding slots like 13th Trial Hercules Abyssways means matching that volatile push-pull rhythm where the board shrinks and grows around sticky symbols. Scourge of Rome, Rise of Olympus, and Pilgrim of Dead each carry a piece of that same DNA – dynamic grids, sticky or expanding symbols in the bonus, and session pacing that lives or dies inside the feature round.
Top picks for slots like 13th Trial Hercules Abyssways are: Scourge of Rome, Rise of Olympus, Pilgrim of Dead. Original provider: Play’n GO. RTP: 96.20% (varies by casino). Volatility: Medium-high.
Quick answer: 13th Trial Hercules Abyssways runs on Play’n GO’s Abyssways mechanic where the grid contracts and expands during free spins while sticky Hercules symbols accumulate, and these alternatives replicate that tension between destruction and accumulation.
- Scourge of Rome – identical Abyssways engine with a 40,000x ceiling and Roman military theme
- Rise of Olympus – Greek mythology on a 5×5 grid with character-driven modifiers and grid-clearing potential
- Pilgrim of Dead – sticky expanding symbols that lock for the entire free spins round at very high volatility
The mechanics behind 13th Trial Hercules Abyssways
The base game runs on a 6×4 grid with 4,096 ways to win. Wilds appear on reels 2 through 5, and when two or more land on the same spin, the Will of Zeus feature gives each one a chance to expand and cover the entire reel. That chance scales inversely with the number of wilds present – two wilds each get a 50% shot, three drop to 33%, four to 25%. It is a system that rewards moderate wild landings more than stacked ones, which is unusual.
Free spins are where the Abyssways mechanic takes over. Landing 3 to 6 scatters awards 10 to 25 spins. Every Hercules symbol that lands becomes sticky and pays from any position regardless of reel gaps. At the start of each spin, Hera’s Wrath burns random positions from the bottom row, shrinking the grid. After the spin resolves, a new full row drops in from the top, expanding it again – potentially up to 46,656 ways. The Pegasus symbol moves all sticky Hercules icons up one row before the contraction happens, keeping them alive longer. Wilds do not appear during the bonus, which means the entire round hinges on how many Hercules symbols accumulate before the grid collapses around them. That creates a session feel where tension escalates with every spin rather than resolving through a single big cascade.

Scourge of Rome
Similarity: This is the direct mechanical predecessor – Play’n GO built 13th Trial Hercules Abyssways on the exact same Abyssways engine, swapping Hannibal’s Roman campaign for Greek mythology. The base game uses the same 6×4 grid with 4,096 ways, the same expanding wild mechanic (called Wild Flip here instead of Will of Zeus), and the same free spins structure where sticky symbols accumulate while Abyssways burns the bottom row. Standout feature: The elephant symbols in Scourge of Rome work identically to Hercules symbols – they stick, they pay regardless of gaps, and the Warhorn pushes them upward just like Pegasus does. Best for: Players who want the identical session rhythm with a lower max win ceiling that some consider more realistic. Drawback: The 40,000x cap versus Hercules’ 60,000x means the theoretical ceiling is 33% lower, which matters if you are chasing the very top end of the win distribution.
Rise of Olympus
Similarity: The Greek mythology connection is the obvious link, but the mechanical overlap sits in how both slots use character-driven modifiers to rescue dead spins and build toward a grid-clearing climax. Rise of Olympus runs a 5×5 grid where Zeus, Hades, and Poseidon each trigger a different modifier on non-winning spins, and clearing the entire grid awards the Hand of God free spins. Standout feature: The rotating god system means the base game intervenes far more often than Hercules’ Will of Zeus, which only fires when multiple wilds land simultaneously. Sessions feel more active between bonuses. Best for: Players who find Hercules’ base game too passive and want more consistent action outside of free spins. Drawback: The 5,000x max win is a fraction of what Hercules offers, and the medium-high volatility translates to a noticeably tighter swing range.
Pilgrim of Dead
Similarity: Pilgrim of Dead shares the core free spins mechanic of sticky expanding symbols that persist for the entire bonus round, which is the exact rhythm that defines 13th Trial Hercules Abyssways. Three scatters trigger 10 free spins where a randomly selected symbol expands to fill entire reels when it appears. Unlike most book slots, these expanded symbols stay locked in place for the remainder of the round. Standout feature: The sticky element is what makes this different from standard Book of Dead-style expanding symbols – once your chosen symbol fills a reel, it does not disappear on the next spin. That creates the same accumulation-under-pressure feel as Hercules stacking sticky symbols while Abyssways erodes the grid. Best for: Very high volatility players who want the sticky symbol accumulation without the added complexity of a dynamic grid. Drawback: The 10,000x ceiling and 5-reel layout mean the absolute peak is lower and the expanding symbol only covers single reels rather than paying from any position across a 6-reel Abyssways grid.
Scales of Dead
Similarity: Scales of Dead sits at the volatile end of the Dead series and pairs the standard expanding symbol bonus with Sandstorm multipliers that ramp up during free spins. The connection to Hercules is the escalating tension inside the feature round – both slots start slow and build pressure toward the back end of the bonus where the biggest hits concentrate. Standout feature: The Sandstorm multiplier mechanic adds a layer that the standard Dead series entries lack. Each retrigger pushes the multiplier higher, which means extended rounds carry exponentially more value. This is the closest equivalent to the way Hercules stacks sticky symbols over a long bonus. Best for: Players who want the expanding symbol mechanic from the Dead series with a steeper reward curve that concentrates value in deep runs. Drawback: Without the Abyssways grid manipulation, the session feels more conventional during the base game. The escalating tension only appears once free spins trigger, and the base game is a standard 5-reel setup with no modifier system.
Cat Wilde and the Doom of Dead
Similarity: Doom of Dead expands the Dead series formula by letting players choose which symbol expands during free spins, and it introduces a second level where an additional symbol can also be selected on retrigger. That layered selection mechanic echoes the way Hercules builds complexity inside a single bonus round – both slots reward patience and extended features rather than single-hit bursts. Standout feature: The multi-level expanding symbol selection means retriggers carry genuine strategic value. Getting a second expanding symbol on top of the first creates a stacked reel scenario that is hard to find elsewhere in the Dead series. Best for: Players who want more control over which symbols drive the bonus. Hercules assigns the sticky symbol automatically, but Doom of Dead lets the game assign the expanding symbol based on what’s been landing. Drawback: The 96.29% default RTP is marginally higher than Hercules, but the 10,000x ceiling and 5-reel layout constrain the top end. The base game also lacks any modifier system, making it quieter between features than Hercules’ Will of Zeus.

When 13th Trial Hercules Abyssways isn’t clicking
If the base game feels too passive between features and you want more consistent intervention, Rise of Olympus fires character modifiers on non-winning spins and keeps the grid alive without needing multiple wilds to land simultaneously. If you like the Abyssways grid manipulation but find the 60,000x ceiling creates unrealistic expectations, Scourge of Rome runs the exact same engine with a 40,000x cap that some players consider more achievable. At £20 / €20 / $20 stake, a 60,000x max win on Hercules would return £1,200,000 / €1,200,000 / $1,200,000 – Scourge of Rome caps that at £800,000 / €800,000 / $800,000 on the same stake. If the dynamic grid is not essential but you want sticky expanding symbols that persist through the entire bonus, Pilgrim of Dead strips back the complexity and delivers the accumulation mechanic on a cleaner 5-reel frame at very high volatility.
FAQs
What slot is most similar to 13th Trial Hercules Abyssways?
Scourge of Rome is the closest match. Play’n GO built Hercules on the same Abyssways engine, and every core mechanic – expanding wilds in the base game, sticky symbols in free spins, bottom-row destruction, the upward-push rescue feature – transfers directly. The only meaningful differences are the 60,000x versus 40,000x max win and the Greek versus Roman theme.
Are there slots with higher RTP than 13th Trial Hercules Abyssways?
Within Play’n GO’s catalogue, Rise of Olympus sits at 96.50% and Rise of Merlin at 96.58%, both above Hercules’ 96.20% default. Book of 99 reaches 99% RTP for players focused purely on theoretical return. The critical caveat is that Play’n GO uses five RTP tiers, so the actual rate at your casino could be anywhere from 84.20% to 96.20% – always confirm in the in-game paytable before committing to a session.
What Play’n GO slots are like 13th Trial Hercules Abyssways?
Scourge of Rome shares the identical Abyssways mechanic. The broader Dead series – Pilgrim of Dead, Scales of Dead, Cat Wilde and the Doom of Dead – all use expanding symbols in free spins with varying levels of persistence and multiplier layering. Rise of Olympus matches the Greek mythology angle with a different grid format and character-driven modifiers.
Can I play slots like 13th Trial Hercules Abyssways for free?
Demo mode availability depends on the casino and your jurisdiction. Most Play’n GO titles offer free play through casinos that carry the provider’s portfolio, though some regions require age verification before accessing demo versions. Check whether your preferred casino provides demo access for the specific title before committing real funds.
Closest mechanical match: Scourge of Rome. The Abyssways engine, sticky symbol behaviour, and free spins structure are identical – the only variables are the max win ceiling and the visual theme. Best overall alternative: Pilgrim of Dead. It captures the sticky expanding symbol accumulation that defines Hercules’ bonus round, strips away the grid complexity, and delivers it at very high volatility on a proven 5-reel frame. For players who want the Greek mythology atmosphere without the Abyssways mechanic, Rise of Olympus keeps the thematic connection and adds far more base game activity through its rotating character modifier system. Whichever direction you choose, check the in-game paytable for the RTP tier at your casino before starting a longer session.
