13th Trial Hercules Abyssways Slot Review
A domed temple sits on a rock ledge, cypress trees climb the cliff beside it, and a thin waterfall spills past its twin on the far side. This is 13th Trial Hercules Abyssways, and the ground under those temples is not to be trusted: the whole game is built to burn and rebuild its own reels. It’s a Play’n GO release running a 6×4 grid with 4,096 ways to win, 96.2% RTP, mid to high volatility and a 60,000x win ceiling. The studio has been down this abyss before in Legacy of Undead Dragon ABYSSWAYS, and the game joins a catalogue holding Book of Dead. Twelve labours earned Hercules his place among the gods; this thirteenth asks for one more.
Symbols, Ways and the Will of Zeus
Wins pay left to right for adjacent symbols, starting on the leftmost reel, and only the highest combination counts per symbol. When multiple ways land in one round, they’re all paid and added together. Feature and scatter wins join the tally at the end of the round.
On the 6×4 grid, matching symbols landing in sequence on adjacent reels can pay several ways at once, and that’s how 4,096 routes turn into a single spin’s total. Two figures from the myth front the paytable, flanked by its iconography and the usual card royals. Hercules is the only symbol that pays for two of a kind; everything below him needs three. Every value is a multiple of the total bet:
- Hercules: 0.5x for two, 1.5x for three, 3x for four, 6x for five, 12x for six
- Hera and Zeus: 0.8x, 1.6x, 3x and 6x for three to six
- Grapes, Vase and Helmet: 0.5x, 1x, 2x and 4x for three to six
- A and K: 0.3x, 0.6x, 0.8x and 1.4x for three to six
- Q, J and 10: 0.2x, 0.4x, 0.6x and 1x for three to six
Wilds land on reels two to five and substitute for everything except scatters. That’s the whole of the wild’s job in the base game, but there’s a twist attached: land two or more wilds in a single spin and the Will of Zeus kicks in, giving each wild that forms part of a win a chance to transform into a full-reel expanding wild.
The transformation odds depend on how many wilds landed, and the pattern is counterintuitive: the more wilds on screen, the lower each one’s individual chance. Two wilds give each a 50% chance, three give each 33%, and four give each 25%. Four wilds all transforming is the rarest outcome; two connecting cleanly is the likelier payday.
The expanding wild only applies to wilds that are already part of a winning payline. A wild sitting between two misses does nothing, no matter how many of its brothers landed alongside it. The feature rewards clusters, not volume. Wilds don’t appear at all during free spins, so Will of Zeus is a base-game event only.
As wilds land, Zeus’s thunder builds visually and the background shifts with it. It’s purely cosmetic, tracking nothing about when the feature next fires, but it gives the base game a bit of movement between wins.
Hera’s Wrath: Free Spins and the Abyss
Scatters pay nothing themselves; they trigger the round. Landing three, four, five or six of them awards spins in kind:
- 3 scatters: 10 free spins
- 4 scatters: 15 free spins
- 5 scatters: 20 free spins
- 6 scatters: 25 free spins
Each scatter that lands during the round adds one more spin, and the round can run all the way up to 50 free spins. Retriggers are the only way past the initial award, so a scatter-heavy round builds serious length.
Free spins run on different rules to everything above them. All Hercules symbols become sticky, lock in place and ignore reel gaps, paying anywhere on the free spins grid. Hercules stops needing adjacent reels and simply pays for being there, and every sticky one that survives keeps earning.
The round’s namesake, Hera’s Wrath, is where the abyss comes in. Each free spin runs the same three-step cycle:
- A random amount of symbols at the bottom of the reel set burn at the start of the spin
- All burned symbols fall away at the end of the spin, shrinking the reels
- A new full row is added on top between spins, growing the reels again
The reel set never sits still, and the payway count climbs with it, up to a possible 46,656 payways. The rhythm matters: burning rows threaten to swallow the board while fresh rows stack above, and the sticky Hercules symbols ride the middle of it.
Because the burning is random, the board’s size swings spin to spin. A heavy burn followed by a single added row leaves the grid smaller than it started; several light burns in a row let the rows stack and the payway count compounds quickly.
How long the round runs and how much of the board survives are two separate questions, and the answers rarely line up. Pegasus is the symbol that tilts them: it can land during the round to protect the herd, moving every Hercules symbol one step clear of the fire before the burned positions drop away.
Should fewer than three Hercules symbols be on screen when Pegasus arrives, it tops the count back up to three before anything else happens.
Bets are set with the plus and minus buttons, one step at a time, and can’t be changed while a round or feature is in play. Free spins run at the bet that triggered them. If a game is disrupted, the round is stored and resumes from the point of interruption.
Our Honest Verdict
Overall Rating: 7.7/10
This is a game of patience dressed as a labour. You sit on a cold cliffside, watch the thunder build, and wait, because the base spin offers little besides an occasional expanding wild and whatever the royals cough up. The reason to choose it is the round at the bottom of the abyss: a board that burns, rebuilds and grows while a sticky cluster of heroes climbs away from the flames.
That round is the best thing here by a distance, and it’s genuinely well made. The strength isn’t the 60,000x number, it’s that the round escalates on its own logic, so a long one feels earned rather than granted. The weakness is everything above it: the paytable’s ceiling of 12x means the base game can’t bail you out, and for long stretches it won’t try.
It suits players who like the build, who don’t mind a quiet spell in exchange for a round that swells to 46,656 payways. Anyone who wants action on every spin will find the wait punishing. The thirteenth trial rewards those who endure it, and there’s a fitting myth in that.
