In Monster Madness, friendly aliens have landed on Earth, and they want to help you win big prizes in their three-reel game with line wins, wilds, multipliers, and free spins. And, the fact that you can create winning combos with the alien symbols horizontally, vertically, and diagonally means that your chances of winning are enhanced with every spin.

Our Verdict:

The Monster Madness slot by Tom Horn Gaming is immensely fun to play, partly because you can form winning combos in several different ways, and also because the special symbols such as wilds, scatters, wild multipliers, and free spins make it possible for you to scoop generous cash prizes with as little as 2p per spin. We also love the comical animations and detailed graphics that Tom Horn Gaming has employed in Monster Madness. So, if you're looking for some innovative extra-terrestrial entertainment, this is the game for you!


The Monster Madness slot is set in a futuristic city which could well be somewhere like London or New York. Impressive skyscrapers dominate the stormy skyline, and if you look closely, you can see tiny cars zipping across the flyovers and along the main roads.

The view that Monster Madness affords you is quite dazzling, but what grabs your attention the most is the two-headed alien wearing a yellow knitted jumper who's hovering next to you, looking expectantly at the reels.

The high-value symbols are represented by the four aliens, and the low-value symbols are the five silver playing card symbols. To achieve a win, all you need to do is land three matching symbols in a diagonal, vertical or horizontal line across the three-by-three grid.

Wild Symbol:

To help you win more frequently, the Monster Madness slot game has a wild symbol (N.B., the laser target), and it can replace any symbol except the scatter. Also, it cannot substitute for the Scatter Wild symbol which appears in the Monster Madness bonus game.

Bonus Feature:

Land three scatter symbols anywhere in view while playing Monster Madness, and you get five free spins.

In this special feature of the Monster Madness slot, the Scatter Wild symbol comes into play and as well as multiplying all wins by x2; it can reward you with up to eleven extra free spins. If more than Scatter Wild contributes towards a win, their values are multiplied together.

Gamble Feature:

Every time that a winning combination is created in the Monster Madness slot game, you're given the option to "Collect" or "Gamble" your win. N.B., pressing the "Spin" button following a win automatically collects your prize.

Although the Gamble feature in online slots isn't for the faint-hearted due to the risk involved, it does give you the chance to double the size of your last win. All you need to do is pick whether you think the next playing card to be drawn will be red or black. If you're right, your prize is doubled, and you can choose to Collect or Gamble again, and if you're wrong, you lose your prize and return to the main game.
