There is a white block wild symbol and it will substitute for all of the other blocks to help and form winning combinations.
The game does not have a scatter symbol.
When you land one or more winning combinations then Medusa turns on her gaze to turn them to stone. The stone symbols then drop out of the disc and more blocks will move in from the right to fill the gaps. With a bit of luck, this will form more winning combinations and the process will repeat itself. Better yet, each time this happens the payout multiplier will increase by 1x with no maximum.
Medusa’s Gaze has a top payout of 10,000x for landing eight gold blocks on a payline. The purple block can payout up to 7,500x, the yellow block up to 5,000x, the pink block up to 2,000x, the light blue block up to 1,000x, the light purple block up to 500x, the green block up to 250x, and the brown block up to 150x.
