3 Wonders Medusa

If you’re searching for Greek mythology with a feature-heavy twist, 3 Wonders Medusa by Relax delivers with its mythological designs. Adventure through the age of heroes and battle mythical beasts in this title with a max win of up to 7,000x your stake. This online slot plays on a 5x3 grid with 25 fixed paylines, where wins are made by matching symbols from the left across consecutive reels.

This slot’s main feature is the “3 Wonders” Bonus Spins system: each Scatter can unlock a different Wild upgrade, and the upgrades can stack together in the same bonus round.
Here are the standout features to watch for:
Wild Grow Row: During Bonus Spins, a landing Wild can turn symbols on reels 2–4 into Stone Wilds, quickly filling lines.

Contagious Wild: The curse spreads by converting adjacent high symbols into Stone Wilds for wider coverage.

Wild Grow Reel: A landing Wild can transform its entire reel into Stone Wilds, creating bigger connections.
