A dark sinister castle, an obsessed scientist and bloodcurdling experiments are waiting for the gamers who dare open this gloomy slot. The symbols seem to have been adapted from an animated horror film but if you get over your fears, the coin awards and bonus features will definitely make you happy and want to keep on playing again and again.

The gaming action takes place over 20 adjustable paylines, each accepting 1 to 10 coins. As coin denominations range between $0.01 and $1.00, you can inject up to $200 into every spin. Surprisingly enough, the slot has no wild symbol but its absence if offset by devilishly rich features. The largest jackpot in the slot is $25,000 and is all yours if you align five slot logos across a payline.

Bonus features

The Electrifying Bonus is a key attraction of the slot that is activated by two or more adjacent monsters. Should this happen, you get an instant award of up to x100 a total bet and are then transported to a formidable dungeon with a green monster chained to the electric chair. Choose 3 out of 12 voltage meters and electrify the scary monster three times. Each pick gives you a random coin award.

The Knife Switch is another scatter that initiates 7 to 9 free spins at a x2 multiplier. During free spins some symbols have a higher value than in a base game. For example, hitting five electric switches on the reels awards a maximum of $20,000. Sounds great?

Franken Cash is one of the most extraordinary video slots ever released by Microgaming, though not an exceptional one concerning jackpot amounts.
