With its futuristic graphics, free spins feature, and wilds, it offers way more than your typical three-reeler, plus it allows you to create wins using diagonal, horizontal and vertical lines instead of paylines.

Our Verdict:

The creator of Monster Madness is a company called Tom Horn Gaming, which is best-known for producing online slots and casino games like Monkey 27 and Blackbeard's Quest. The playing experience offered by the Monster Madness slot is full-on fun from start to finish thanks to the easy game rules and generous free spins bonus. You can try it out at Quartz Casino in demo mode or play it for real to be in the running for cash prizes with stakes of 20p to £100.


Monster Madness is set in a sprawling metropolis which is depicted in incredible detail. Skyscrapers dominate the cloudy skyline, and lights from office buildings and hotels can be seen at the same time that grey clouds float past. Look down at the roads, and you'll see tiny cars making their way through the city while small spaceships whizz along the overpasses.

On the right-hand side of the screen, you'll find one of the cute aliens who give the Monster Madness slot game its name, and he's surveying the city in awe as he floats over it on a hoverboard. He also occasionally turns to face you with a big grin.

The playing area is made up of a three-by-three grid which is populated with friendly alien characters along with playing card symbols.

Wild Symbol:

In Monster Madness, you have better chances of winning cash prizes thanks to the wild symbol which looks like a laser target. It can substitute for all symbols apart from the scatter and Scatter Wild.

Bonus Feature:

You'll be pleased to hear that the Monster Madness slot comes with a Free Spins Feature, and you can unlock it by getting three silver spaceships (N.B., the scatter symbols) anywhere on the reels.

Initially, you get five free games on a reel set that uses all of the base game paytable symbols bar the scatter. In place of the scatter, you have a Scatter Wild which can replace any other symbol to create a win. It also gives you between five and eleven extra free spins plus instant win amounts ranging from 0.5x to 100x your stake when two or more of it come into view during the Monster Madness Free Spins feature.

Gamble Feature:

If you'd like the opportunity to win more cash while playing the Monster Madness slot game, there's the option to gamble any or all of your wins by playing a simple guessing game. All you need to do is choose red or black as the colour of the face-down playing card, and if you're right, your original win will be doubled.
