How To Play

Stepping into the shoes of Dr Frankenstein’s faithful assistant is easier than you think. To begin, you’ll need to set the amount of LINES you want in play, your BET LEVEL and your COIN VALUE. To do so, use the (+) and (-) buttons on either side of the relevant tab. Happy with your choices? Hit SPIN to start experimenting! You can lay it all on the line with the MAX BET option, or sit back and relax with the AUTOPLAY feature to let the game spin itself for you.

Linked Wilds

This brand new feature will have you on the edge of your seat! Linked Wilds turn 2 or more nearby Wilds into extra Wild symbols. And you know what that means, right? BIGGER and BETTER chances to bag a winning combo and get the riches reeling in! Keep an eye out for these Wilds:

LIGHTENING WILDS appear in the main game on reels 2, 3 and 4 and substitute for all symbols except the Scatter symbols. They can shock 2 or more nearby symbols into extra Wild symbols.

FIRE WILDS appear in the Free Spins round on reels 2, 3 and 4 and substitute for all symbols except the Scatter and Multiplier symbols. They can ignite 2 or more nearby symbols, turning them into extra Wild symbols.

Burning Mill Free Spins Feature

Set the reels ablaze with this scorching hot feature! Get 3 or more Windmill Free Spin symbols on the reels to activate it. You’ll then immediately be given 10 free spins, each with a guarantee of Fire Wilds on every spin, PLUS an ever increasing Free Spins multiplier (up to 5x) form some truly monstrous payouts. Here’s the deal:

Things kick off with an angry mob chasing the monster to an old, abandoned mill. After this, all Wilds will become Fire Wilds, and your aim is to combine them with the win multiplier to get some ridiculous riches reeling in! You should bear in mind that the Multiplier symbol will appear on reel 5 and will increase by 1 on each spin (up to 5x). Each time you win a new multiplier, it will ignite a different part of the reels as follows:

2x multiplier – set the bottom of the reels on fire
3x multiplier – ignites the left and right sides of the reels
4x multiplier – sets the top of the reels ablaze
5x multiplier – turns the mill into a raging inferno!

And to top it all off, the feature can retriggered! Get 2 Windmill Free Spins symbols to win another 5 free spins; get 3 to win another 10 free spins. Set your wins ablaze for scorching payouts!
