MEDUSA is our 3x5, 243 ways slots game. During the free games round, wild symbols can expand up to seven symbols high, as opposed to the base game’s three rows. This will automatically increase the number of paylines open to them. If the wilds were, indeed, to reach seven symbols high, you would ultimately be playing with as many as 7,203 ways to win. On top of that, this no-frills slot game also allows players to retrigger the free spin bonus indefinitely.
