Theme, Graphics & Soundtrack

The graphics are clear and opulent, sometimes terrifyingly so. Suspend your disbelief that Dr Frankenstein and his glamorous assistant would have looked so airbrushed back in the early 1800s as you marvel at his quiff and her gravity-defying mallen streak.

In the background, we see a green-lit lab complete with simmering, steaming potions and some rather glossy looking lab equipment. The card icons are similarly glassy but with a nod to the monster in the form of a bolt through their necks... ouch!

Dr Frankenstein Bonus Features

There are a number of bonus features available in this popular online slot.

Wild...and Locked Wild?

Dr Frankenstein’s monster is rather large, so just one Wild symbol was insufficient for his bulk. Instead of normal Wilds, you’ve got Locked Wilds. They can both substitute for all other symbols. At the start of each spin, any symbol can turn WILD

Mystery Symbol Feature

If you have stacks of the same symbol, when you start a spin, they change to a random symbol.

Random Multipliers

So, you’ve got a win...great! How could that be even better? Well, if there was the chance for the win to be randomly multiplied between 2x and a massive 25x, that’s how…

Free Games

You’ll be rewarded with eight free spins if you land five adjacent Green or Red Frankensteins. Every additional Green or Red Frankenstein awards you three additional free spins. All of the Red Frankensteins on the reels transform to Locked Wilds during free spins. Plus, you can reactivate free games during the free spins... just like the doctor, but this time you won’t need a lightning volt.

Our Verdict

This should be the ultimate title within the horror themed slots genre. Everyone is familiar with the myth of Frankenstein, and there is a deep range of existing content to draw on in order to build a game stuffed with interesting features.

The gameplay is smooth, the scene is well-set and the feature rewards, should you be lucky enough to land any, are quite generous.
