Legend of Perseus plays on a 5x5 grid where wins form through all-ways-pays mechanics. When symbols match, they merge into the bottom-most symbol on the reel, which increases the win multiplier. After merges occur, new symbols cascade onto the reels to fill the empty spaces, potentially creating further winning combinations.

The Medusa free spins bonus is triggered by landing 3 or more scatter symbols. During this round, a chosen symbol becomes sticky and remains in place, growing the multiplier with each spin. This game is suited for players who prefer high volatility gameplay and mechanics that focus on building multipliers through cascading wins.
