Play Mental Money Monsters for Free

The monster's lair is full of all sorts of monsters which can pop their heads through trap doors to scare you at any moment – but just remember the five monsters detailed above – as these are the ones that will win you the mental money!

You may well find some of the Monsters playing poker when you arrive – but don't be afraid to interrupt their game as even their playing cards can win you prizes of up to 125 your line-bet. All the monsters you hunt down are also capable of multiplying your line-bet with the orange crab-eyes monsters up to 250x, the scary blue monsters up to 400x, the purple five-eyed monsters up to 750x, the green one-eyed monsters up to 750x, and the wild red monsters up to 10,000x.

The wild red monsters can also replace all other base symbols to create even more winning pay-lines. Watch out for the trap doors at all times, and if 3-5 are in view at once this will trigger the Trap Door Bonus in which you can pick a Trap Door to reveal a prize. Also watch out for the Free Spins Symbol as 3-5 of these triggers the Free Spins Feature, with 3 triggering 15 free spins, 4 triggering 25 free spins, and 5 triggering 100 free spins, during which all prizes are tripled. However, any pay-line made up with a wild will be multiplied by 5x during the Free Spins Feature. There's also Mental Money Monster symbols to find and 3-5 of these trigger the Mental Money Monster Feature in which you must spin a wheel to move round a trail to increase your prize multiplier until the wheel lands on stop.

You might think that a big-money Monster themed slot would have scary stakes – but it doesn't. Simply choose to play 1 to 20 lines on any spin, then place your line-bets of between 0.01 coins and 25 coins. This allows a minimum bet of 0.01 coins a spin, and a maximum bet of 500 coins a spin.
