Gameplay, Features & Editorial Guide

FEATURES

Core Features

Abysswaysu2122 Pay Mechanic

During Free Spins, the board dynamically changes as Hera removes symbols from lower rows, and new symbols collapse from above, creating fresh winning combinations.

Will of Zeus

When at least two Wild symbols land, Zeus may intervene with thunderbolts to expand them into full reels. The probability of this occurring increases if the trigger conditions are not met or only one Wild appears, building up a 'charge' for a more impactful event later.

HOW IT PLAYS

Gameplay & Mechanics

Players set their desired bet before each spin, aiming to land matching symbols from left to right. The game incorporates a cascade tumble mechanic, where winning symbols are removed, and new symbols fall into their place, potentially creating consecutive wins from a single spin. This dynamic reel action, especially during the Free Spins, keeps the base game engaging while players pursue the bonus features.

Depending on the number of Scatters, players receive 15, 20, 25, or 30 Free Spins. During this round, Hera removes 3 to 9 symbols from lower rows after each spin, with new rows collapsing from above, constantly altering the game board.

Pegasus & Hercules Feature

During Free Spins, Hercules symbols pay from any position on the reels. If fewer than three Hercules symbols are present, Pegasus may appear to summon up to three additional Hercules symbols. These special 'Super High' symbols float upwards with each subsequent spin and are immune to Hera's Wrath, remaining on the board.
