An ugly and scary creature with snakes instead of hair, the Medusa was a character in Greek mythology whose 'special abilities' included turning people into stone. In the world of Online Slots, however, Medusa doesn't look that ugly and is not going to harm you, as her purpose here is to reward you.
Indeed, in Medusa themed slots this creature is even somewhat nice and beautiful, and this is not for nothing: ugly creatures are not very likely to share their treasures with you, but Medusa will: she has a lot to share, don't even question that, and you just need a bit of luck to get some of her riches.
There are slots dedicated totally to Medusa, and in this case her symbol will act as wild or Scatter, of course, to say nothing of it being high paying. Other slots feature Medusa as just one of the Greek mythical characters, alongside with other gods, creatures, and heroes.
