At 95.94%, the RTP is slightly below the industry average of ~96%. While this is typical for many popular slots, players should be aware of the slightly lower theoretical return.

About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Medusa features scatter symbols that can trigger free spins rounds.
