Based on movie “Frankenstein,” Monster Money Slots features a few particularly freaky looking monsters. But one of the unique features in this slot game is that the Electric Rod pays no matter where it appears on the reels. One of the coolest features, however, is the bonus round in which you select from eight doors in a haunted house. Find a monster behind any five doors, and you win a prize. If you find the nutty Professor, however, and all prizes are tripled.
