How to Play Monster Mania Slot Online
Monster Mania is a five rollers and nine paylines slot game by Microgaming. It starts the game when you click on the button “tick,” but before that, you have the option to set the coin size to as many paylines as you want. Before each turn, you can create up to nine paylines.
The entire payout schedule is available by clicking on the “View Payout” button. You might have to dig a little to find it, but next to the “Monster Mania” logo it’s there. All the correct tables are in front of you when you get there.

Interactive Features
Wilds. There is a wild emblem called the Monster Wild which, except for the set, substitutes for everything else for the completion of winning combinations. The Monster Wild emblem will only appear on reels 2, 3 and 4 of the five reels. The wild symbol is no mistake because it’s what we call the wild monster and it replaces another symbol, except for the scatter, for putting together winning combinations.
Scatters. There is the “Scatter Brain” symbol in a special feature of this slot game, as it doesn’t have to show on an enabled payline to win. It derives scatter wins through the multiplication of the number of Scatterbrain credits. Besides a scatter symbol, it has a “wild” which carries the name ScatterBrain.
