The symbols you will land on the reels include low-value A to 10 royals, as well as better paying helmets, swords, temples, and vases. The snake heads symbol is the wild that replaces all other symbols bar the scatter, and pays 200x your stake for 5 OAK.
Medusa herself is the scatter that appears on reel 3 only, and triggers the Medusa feature. When activated, the Medusa symbol turns two randomly picked symbols into wilds.
Medusa is quite an unsophisticated slot both in terms of payout and mechanics. There are no free spins or bonus rounds. Your best chance of landing a sizeable win is by filing the reels with wilds and get 2000x your stake. Frankly, we expected Blueprint to do better. Still, it has plenty of fantastic titles to switch to in case Medusa fails to meet your expectations.
*Medusa slot by Blueprint is expected to go live by the end of June, 2019. It should not be mistaken for NextGen’s Medusa Megaways.
