Wrath of Medusa in brief

Wrath of Medusa is a slot from Rival Gaming released in June 2020 that puts the player against the gorgon's wrath armed like an ancient warrior. The theme is supported by a helmet, shield, sword and bow, so the game approaches the Medusa myth in a combative spirit rather than pure horror.

The theoretical max win is 500× the stake. No RTP figure is listed in our game info, and we don't guess percentages — we'd rather leave it open than publish a number we haven't seen.

Theme and atmosphere

The palette leans on black and grey, highlighting the darker side of the petrified Medusa tale. Alongside card symbols, higher-tier imagery is coloured by gems, weapons and warrior gear.

True to Rival Gaming's style, the game stays a straightforward Ancient Greek adventure: at the centre are the gorgon's stare and the warrior's tools that defy it. The mood leans toward a mythic battle tale where the hero's gear stands against the gorgon's petrifying power, and the card symbols keep the base rhythm clear.

Features

The feature list includes Expanding Symbols, Free Spins and Free Spins Mode Choosing, where the player can influence the nature of the bonus before it begins.

A distinguishing mechanic is Respin Wild combined with Sticky Wilds: a wild can remain in place and trigger a respin. Scatter symbols control access to free spins.

RTP, volatility and max win

The official RTP percentage for the game has not been published in our data, so it is not shown on this page. The same applies to volatility, which the game does not publish as a number and we do not guess it.

The theoretical cap is 500× the stake. That's a modest peak compared to newer Medusa-series slots, which typically indicates a tighter and less extreme win profile.

Who the game is for

Wrath of Medusa suits a player who appreciates a straightforward antique theme, a choice of free spin type and a Respin Wild mechanic without a complicated feature parade. Because RTP and volatility are not disclosed and the max win cap is a modest 500x, set a clear bankroll and try the game in demo first.

Gameplay

Wins occur when identical symbols form a combination according to the game rules. Wild substitutes for other symbols in winning combinations, and expanding symbols can fill multiple positions at once, increasing hits in a single spin.

The exact grid layout and the precise paytable multipliers are confirmed in the game’s info panel.

Free Spins and bonuses

Free spins trigger according to the game info when a sufficient number of Scatter symbols appear. In Free Spins Mode Choosing the player selects the free spins type before the bonus starts.

Respin Wild and sticky wilds (Sticky Wilds) can remain in place and trigger respins. The exact trigger conditions and number of respins should be checked in the game's rules.
