Greek Mythology Theme and Characters

You play the part of a rescuer saving lost souls from Hades, with prizes to win along the way. The artwork is strong, in keeping with the other Age of the Gods slots, and the audio effects reinforce the theme.

The upper-value characters are the mischievous Hermes, Nyx, goddess of the night, and Persephone, queen of the underworld. The middle-value symbols are Hades’ staff, lost souls, a coin and Cerberus, the hound of hell. The lower-value symbols are three burning card icons: K, Q and A.

Tartarus Wild and Charon Scatter

The Tartarus wild replaces the other regular symbols and also forms its own winning payline, worth up to 10,000x your total stake.

In Greek mythology, Charon was the ferryman who carried the dead across the River Styx. Here he is the scatter, paying 5x, 25x or 100x your stake for sets of 3, 4 or 5.

Gates of Hell and Thread of Fate Bonuses

The Gates of Hell bonus is triggered by 3 Cerberus symbols on a payline. You choose a door to descend to the underworld and rescue a lost soul, but choose carefully: the wrong door leads to Cerberus and ends the feature.

The Thread of Fate bonus is triggered by 3 Fate Sister symbols on a payline. You pick threads to cut, each revealing a cash multiplier prize, and keep going until you reach the thread that will not cut, which ends the feature.

Age of the Gods Progressive Jackpots

The game has four jackpot tiers: Power, Extra Power, Super Power and Ultimate Power. They are linked to other games, which lets them grow faster and larger. The jackpot feature triggers at random, and a bigger bet improves your chances, although the jackpots are hard to hit whatever you stake.

In the feature, 20 coins are shown in a 4×5 pattern, each hiding one of the four jackpots. You keep turning coins over until three match, and that jackpot is yours.

Playing on Mobile, Tablet and Desktop

The slot runs on Android and iOS devices as well as desktop, and the page describes it as a higher variance game played with 20 coins. Casinos set their own rules and bet limits, so check the game’s info screen before you play.
