Medusa (GMW) in brief

Medusa is a slot from GMW released in 2023 that draws directly from the Greek gorgon myth. The game stands out in our catalog with a progressive jackpot and a traditional gamble mechanic.

The game offers a classic feature package from bonus game to free spins and multipliers. RTP, volatility or theoretical max win are not listed in the game’s details, so we do not publish figures we have not seen.

Theme and atmosphere

The theme tags are ancient civilizations, Greek imagery, mythology and Medusa herself. The color palette leans green and purple, giving the game a poisonous, magical hue — fitting the snake‑haired gorgon's nature.

Ring (Ring) appears on the theme list as a higher-level symbol, and the mythological atmosphere emphasizes Medusa’s role as the game’s central figure.

Features

The feature list is rich: it includes Bonus Game, Bonus and Scatter symbols, Free Spins, Multiplier, Respins and Wild. The Wild symbol substitutes for other symbols in base-game win combinations, and Scatter symbols act as bonus triggers.

The game also has a Risk (gamble) feature (Double game) that lets you try to double a single win at risk. Above all of these sits a progressive jackpot that grows and can be triggered according to the game's internal logic.

Progressive jackpot and gamble

A progressive jackpot sets this game apart from most Medusa slots: the pot grows over time and can be won in a single spin. We do not state the exact value of the pot or the triggering conditions — those are confirmed in the game's info panel.

The Gamble feature offers an optional risk to increase a win after a paid spin. This is an extra risk, not part of the game's normal flow.

What information is missing

The RTP percentage, volatility and theoretical max win for this game are not listed in the information available to us. We do not guess these figures: because of the progressive jackpot the win potential could nevertheless be significant. Exact numbers and bonus multipliers are confirmed in the game’s own info panel.

Always set a session budget and try the game in demo before playing with real money, because without a stated volatility you can't anticipate the swing level in advance.

Gameplay

In the base game, wins are formed when the same symbol lands on consecutive reels according to the game's paylines. The Wild symbol substitutes for other symbols in winning combinations except for bonus and scatter symbols, and the Respins mechanic can deliver additional hits on a single spin.

Exact multipliers and the structure of win lines are confirmed in the game's own info panel.

Bonuses, jackpot and gamble

Free Spins and the bonus game are triggered by a sufficient number of Scatter or bonus symbols appearing. During bonuses multipliers can increase wins. The number of symbols required to trigger is confirmed in the game's info panel.

The progressive jackpot grows over time and can be triggered according to the game's internal logic. With the gamble feature you can try to double a win after a paid spin. We do not state the jackpot's exact value or the individual multipliers of bonuses — those are confirmed in the game's info panel.
