Wilds can land anywhere on reels 2 – 6, and if at least 2 appear, they randomly trigger the Will of Zeus feature. A little lightning bolt to the left of the reels zaps the wild symbols, causing them to expand across all 4 rows of their reels. The odds of this feature improve with more wilds in view.
The temples of Mount Olympus scatter symbol in any 3, 4, 5, or 6 places lead to 10, 15, 20, or 25 free spins respectively. Several modifiers are active throughout, including an extra free spin from each new scatter to a maximum of 115 in total.
The action moves to inside a temple, where the Abyssways mechanism is now active.

Unusually, the Hercules / Pegasus wild symbol can’t appear during the free games.
Play’n GO quote a maximum win of 60,000x the bet, but you’ll need a perfect combination of symbols across as many free spins as possible to reach this huge target. Still, if you are lucky enough to hit this epic level at the maximum stake, you collect a massive 6,000,000.00 prize.

Sticky Hercules symbols that pay on any reels are also held back for the bonus games, but while Pegasus won’t always save him from the abyss, he can lead to win after win as more and more start to fill the grid.
