13th Trial Hercules Abyssways Demo: Play Play’n GO’s Special Ancient Greek Slot
Play’n GO is one of the most prolific developers in the gambling industry, releasing multiple new games on a monthly basis. These are invariably of the highest standard, with bold themes, immersive features, and detailed graphics. The studio’s latest release, 13th Trial Hercules Abyssways, ticks all these boxes and has the added strength of being available at many of the best casinos around.
This review will delve into the gameplay — including how there are up to 46,656 ways to win — and we have also included the full 13th Trial Hercules Abyssways demo so that you can experience the Greek theme for yourself.
13th Trial Hercules Abyssways Features
The 13th Trial Hercules Abyssways slot has been designed to stand the test of time. Play’n GO is a developer that is renowned for excellence and depth, but this is a detailed game even for them. Even on moderate play sessions you will notice that spins feel different each time — so let’s take a closer look at the main highlights.
Will of Zeus
If your spin lands at least two Wild symbols then you will unlock the Will of Zeus mechanic. This is a sight to behold and will see Zeus and his thunderbolts potentially transform the Wilds into full reels. If only one Wild appears then the grid will “remember” this and make Zeus more likely to appear on future spins; you can almost sense how close you are to this with the accompanying crackling.
13th Trial Hercules Abyssways Free Spins and Bonus
Free spins are a huge part of the game and the main 13th Trial Hercules Abyssways bonus. The Abyssways mechanic can be launched by landing three scatter symbols. This adds real variety to each free spin by creating a dynamic grid. During this mode, symbols will fall and potentially add more matching symbols and wins to your account balance
The breakdown is as follows:
- 3 Scatters: 15 Free Spins
- 4 Scatters: 20 Free Spins
- 5 Scatters: 25 Free Spins
- 6 Scatters: 30 Free Spins
Hera’s Wrath ensures that the reel is dynamic during free spins and up to nine symbols are replaced from lower reels. The collapsing reels is a unique animation that can result in substantial wins.
It is also worth noting that scatter re-triggers are in place: every one present during free spins adds an extra spin; this is capped at 115.
Pegasus & Hercules
Mythical Hercules becomes the main character during free spins. If you land fewer than three Hercules symbols then Pegaus will make an appearance and bring more with him — these symbols can also move them away from the collapsing grid.
