Petri Halkola · Slot and casino reviewsUpdated 2026-08-04 · Luvut pelin omista tiedoista
Released by Boomerang Studios on 30. lokakuuta 2025 3 Wonders Medusa vie gorgonin tarinan omaan suuntaansa: mukana ovat teemat Adventure, Gold, Gold-color sekä Greece. Se on yksi katalogimme 103 Medusa-aiheisesta slotista, julkaistu 2025.
The game's official feature list is this time shorter but clear. We played the session ourselves, so below we explain what the listed mechanics actually did on screen — and which details remained behind the info panel.
Mechanics and bonuses
According to the game's official feature list — no guesses
Wild and substituting symbols
The feature list includes Expanding Symbols, Spreading Wilds or Wild Rush and Wild. In our session wilds completed rows already in the base game and stacked into piles during free spins.
Free spins
The game info lists Additional Free Spins and Free Spins. In the session the bonus triggered on a “you've won 5 free spins” screen, and the extra spins increased the counter to eleven spins.
Scatter and cluster wins
The win mechanic is based on the listed Scatter symbols feature. We did not read the grid's exact structure from the info panel, so we will not publish the number of lines.
Free spins: tämä on pelin selkeä päänumero. Bonus alkoi viidellä ilmaiskierroksella, mutta lisäkierrokset venyttävät laskurin yhteentoista, ja juuri näillä kierroksilla pinotut wildit tuottivat session molemmat BIG WIN -ruudut.
RTP, volatility and win potential
What the numbers mean for the player
RTP and its reliability
The reported return 96,02 % is a good level among modern slots.
Volatility and win potential
Medium volatility balances hit frequency and win size.
Pros
- RTP level 96,02 % — above the catalog average
- Fresh 2025 release
Cons
- The maximum win has not been published in our sources
- The base game feels underwhelming without free spins
A straightforward avalanche slot whose best moments are on the free spins
We played through the session and saw the full arc: a calm base game, a “you've won 5 free spins” trigger and on the bonus up to eleven extra rounds where stacked wilds produced two BIG WIN frames. The base game without the bonus feels flat, and because no max win is published in our sources the cap remains unknown. For its mid variance and neat free-spin mechanic, 7,3 is an honest rating.

Game session
We play every catalog slot ourselves before the final review
We played 3 Wonders Medusa ourselves and experienced the full feature range on screen. The base game spins calmly in a gorgon's temple setting: wilds fill rows already in base spins and medium volatility swings delivered small and medium hits at a steady pace before the bonus.
Free Spins began with the “Congratulations — you've won 5 free spins” screen, but extra spins raised the counter to eleven (displayed as “of 11 free spins”). During the spins stacked wilds accumulated on the grid, and the session's biggest hits — two BIG WIN screens — came right here. All images below are from the same session.
Rules and payouts table

Rules and pays – 3 Wonders Medusa
The game’s preview names three separate wild functions: Wild Grow Row, Wild Contagious and Wild Grow Reel.
In the Wild Grow Row example the wilds expand horizontally on the same symbol row.
In the Wild Contagious feature example, the wild spreads its effect to adjacent tiles.
In the Wild Grow Reel example the wilds expand vertically on the same reel.
The demo shows each wild feature on a five-reel, three-row grid.
Wild symbols can appear as stacks several symbols high in demo screens.
The game info confirms that the regular Wild substitutes for all symbols except Scatter.
Stone Wild also substitutes for all symbols except the Scatter.
Stone Wild pays 0,60 for three symbols, 1,60 for four and 6,00 for five at the currency setting in effect.
The game view reports 25 active paylines.
Exact multipliers for the other symbols are not published because the full paytable could not be read during this review.
