13th Trial Hercules Abyssways: Slot Overview
13th Trial Hercules Abyssways is a myth-themed video slot from Play'n GO built on a 6x4 grid with 4,096 ways to win. In free spins the reels can grow, so you can reach 46,656 ways. I found it decent to look at, with Mount Olympus vibes, waterfalls, temples and a proper gloomy Greek atmosphere. It aims big too, with a 60,000x max win, though the medium-high volatility means it can be a bit rough.
13th Trial Hercules Abyssways: Slot Features
Will of Zeus is the base game feature, and it is the bit that stops the main game feeling too flat. Wilds can land anywhere except the first reel, and if 2 or more show up, each winning wild can turn into a full-reel expanding wild. The odds drop as more wilds land, 50% each with 2 wilds, 33% with 3, and 25% with 4.
Free Spins land from 3, 4, 5, or 6 scatters for 10, 15, 20, or 25 spins. During the feature, Hercules symbols turn sticky and can pay even with gaps between reels, plus they can start from any reel. Then Hera's Wrath - Abyssways burns random bottom symbols, which fall away after the spin, while a fresh full row gets added to the top between spins.
Pegasus can show up in free spins as well. When it lands, all Hercules symbols move up one step before the burned positions drop away, and if there are fewer than 3 Hercules symbols on screen, Pegasus tops them up to 3. Any scatter in the round adds 1 extra spin, up to a max of 50. Fair enough, that part is where most of the fun is.

In the base game, when 2 or more wilds land, each winning wild can turn into a full-reel expanding wild. The chance is 50% with 2 wilds, 33% with 3, and 25% with 4.
Land 3, 4, 5, or 6 scatters to get 10, 15, 20, or 25 free spins. Hercules symbols are sticky, can pay with reel gaps, and can start wins from any reel.
During free spins, random bottom symbols are burned, then removed after the spin, shrinking the reels. A full new row is then added to the top before the next spin.
During free spins, Pegasus moves all Hercules symbols up by one row before burned positions fall. If fewer than 3 Hercules symbols are visible, it tops them up to 3.
13th Trial Hercules Abyssways Slot Information
Symbols are split into royals and premiums. The low pays are 10, J, Q, K and A, paying 1x to 1.4x the bet for 6 of a kind. The premium lot are helmet, vase, grapes, Zeus, Hera and Hercules, with 6 matching premiums paying from 4x to 12x. Hercules is the top dog here, no surprise.
Wilds substitute for regular paying symbols, and they only appear in the base game, which is a bit of a shame because they are the ones tied to the full-reel expansion. The scatter is the temple symbol and triggers the bonus from anywhere. I like the theme work on the symbols, even if it is not exactly fresh territory.

Theme & Graphics
Visuals are strong, mate. The game leans hard into Mount Olympus scenery with marble framing, temples on the cliffs and waterfalls in the background, and it all looks crisp on desktop and mobile. I also liked the soundtrack, which has that slow, slightly melancholic feel. Nice touch, though I am not entirely sold on the theme because Greek mythology turns up all over the place in slots.
