13th Trial Hercules Abyssways - Demo & Slot Review

The setting throws you into a high-stakes showdown between Hercules and the gods of Olympus. The backdrop is a sweeping mountain vista with grand temples in the clouds, while the soundtrack delivers an epic orchestral punch with dramatic hits every time something big happens on the reels.

The slot uses a 6-reel, 4-row layout in the base game, but during the bonus this expands dynamically thanks to the Abyssways™ system so rows get destroyed, new ones drop in from above, and the grid constantly changes shape. It offers up to 46,656 ways to win at its largest configuration.

Volatility is high, with a default RTP of 96.2%, though lower versions (94%, 92%, etc.) exist depending on where you play. The maximum win is an eye-watering 60,000x your bet, which is enormous by Play’n GO standards, though realistically, hitting it will be extremely rare. Bets range from €0.10 to €100, making it accessible for casual players and high rollers alike.

The star mechanic is Abyssways™, which makes the grid shift and evolve during free spins. Here’s what to expect:

• Will of Zeus Expanding Wilds – When wild symbols appear on reels 2–5, they charge Zeus’s power. Two or more in view can transform into full-reel wilds, covering their reel entirely for the current spin.
• Hera’s Wrath – During free spins, Hera burns away lower rows of the grid, forcing symbols above to drop down. This opens up space for bigger symbols and better payouts.
• Pegasus Assist – Pegasus can swoop in to save Hercules symbols, moving them up the grid to keep them active for potential wins.
• Sticky Hercules Symbols – Hercules icons that land during free spins remain sticky, counting as wins wherever they appear on the grid until the feature ends.
• Scatters & Extra Spins – Landing additional scatter symbols during the bonus awards +1 spin each, with a theoretical cap of 50 spins.
