Our Free Monster Slot machine has a lot of 'monsters' to shout about. We have made the coin values a monster 50 credits and give players a massive 2000 credits to start with. But watch out because if you bet max with all three paylines activated, you will be out of cash in just over three spins!

Biggest Monster Slots

From the grizzly monsters of horror movies to the cute monsters from kids' films, all play a part in the inspiration of monster slots machines. In this article, we will take a look at the best monster slots machines available. At the end of the article, we'll give you a sneaky little peek at one of the brilliant new slots games that we are currently working on!

Under The Bed Slot.

Overview: To start off with, we'll take a look at a game with more friendly-looking monsters. However, this slot still has a bit of a scary side to it as well!

Under the Bed slot is a Betsoft powered slot. It has five reels and thirty pay lines - a 3D animated slot machine with fantastic graphics and sound effects like many new Betsoft games.

Although not expressly stated, the game certainly takes its inspiration from the kid's movie 'Monsters Inc.' Everything from the monsters under the bed, the children in the game, and the style of the monsters. All look pretty similar to those in the movie.

Around the reels, there are lots of neat animations. From two children standing at the side of the reels watching the action. To monsters jumping out and scaring them. On the reels, there is lots of animation too, all accompanied by suitable sound effects.

After each winning spin, that is not part of a bonus mode and doesn't activate a bonus mode. You have the option to 'double-up' your win by clicking on the 'Double Up' button when active. You enter the bonus round, where you get to guess the result of a dice rolL rolled by one of the monsters. The options are 'Odd' or 'Even.' This bonus feature is an excellent way to double your win, but be careful because if you get it wrong, you will lose all of your winnings!

The game has four sticky wild symbols. Each is an image of a different monster with a special gold border around it. Get a paying combination of either of them, and sticky wild will appear with a random number. The random number is the number of spins that the sticky wild will be active. What makes these even better is the ability to win more than one sticky wild on the reels at the same time.

Getting three or more of the bed symbols anywhere on the reels triggers the second round bonus game. Set in Jesse and Jane's dark bedroom with monsters hiding under the bed.

If the mysterious door symbol lands on the middle of the reels, you get 12 free spins in the lopsided monster bedroom.

You can play the Under The Bed slot for as little as $0.02 per spin and up to $74.98 maximum bet. The coin size, number of coins per line, and number of pay lines are all changeable. However, oddly, when changing the number of paylines, it starts at one and jumps up by two each time, so 1, 3, 5, 7, etc.

The graphics in this game are great. The music and sound effects are bubbly and bounce along to go with the look and feel of the symbols. There is little animation. It is reserved for symbols that are in a winning combination.

Written by Mary Shelley in 1818. The name Frankenstein is often used to refer to the 'monster.' However, Victor Frankenstein is the (fictional character) mad scientist that created the grotesque monster!

Frankenstein and his creation both also feature on the reels as the second-highest and highest paying symbols, respectively. Other symbols include a full moon with dark clouds, a jar with an eyeball in green fluid, and the electrified head attachment. There are also high paying card symbols.

After every winning spin, you have the option to double up your win. By clicking the 'Double Up' button, once it's activated, gives you the opportunity to gamble all or gamble 50% of your winnings. The aim is to guess if a coin flip will be Heads or Tails. Losing the loose will lose your winnings!
