Monster Mayhem

This rewarding slot machine game is chock full of scary symbols that will certainly have you shakin’ in your boots! Keep your eyes peeled for the Monsters Smash and Crash (who also happen to be the Wild symbols), and the City, that will help you out by serving also as the scatter symbol!

Monster Mayhem is a 50-line variable 5-reel online casino slots game where you can win with one of the several different combinations and a local progressive jackpot plus a random jackpot. You can set your bet from $0.01 to $100.00. The scatter (the City symbol) will help you by multiplying your winning amount, depending upon how many times it appears on the reels.
