Mental is a horror-themed slot game created by Nolimit City. Unlike other horror games, here there is nothing even remotely funny. Set in an asylum, you’ll come across torturous “healing” methods of the 40s and 50s that doctors then believed to be advantageous for mental patients. The poor patients beg to disagree! The maximum win of the game is the devil’s number 66,666. You may be able to win this many times your bet if you dare to enter the asylum and play Mental at Guts casino!


  • Horror-theme set in an asylum

  • Extreme volatility and 96.08% RTP

  • Game highlights include Fire frames, Dead patient multipliers, Enhancer cells, Mental transform and 3 types of Free Spins

  • The maximum win is 66,666x the bet


Nolimit City has created several popular slot games that you’ll find at Guts. This up-and-coming game producer certainly didn’t show any limits at the creation of Mental. The game is as creepy and scary as a horror game can be. Using only sepia colours the graphics transport players back in time and you’ll feel happy you live in New Zealand now and not in the USA 80 years ago where most lobotomies were performed.

The 10 spooky symbols of the game are body parts - bones of a hand, kidneys, brain, heart, and eye and five mental patients. Patient 1 pays the most - get 5 of his matching symbols and you’ll win 5x your bet. The game is played on a 3x2x3x2x3 format grid and therefore there are 108 ways to win.

The Fire frame feature may split symbols during the main game, and it can appear in any of the 13 positions. The Dead patient feature is activated by landing 2 Dead patient symbols. When this happens one of the patient symbols will be revealed with a multiplier of 5x, 10x, 15x, 30x, 100x, 200x, 500x, 1000x or 9999x.

Fire cells on reels 2 and 4 activate the Enhancer cells that reveal special symbols that can be:

  • Patient symbol

  • Dead patient symbol

  • Regular wild

  • xWays reel expansion symbol

  • xSplit symbols which divide into wilds

  • xNudge wilds that become fully visible on the reels increasing the multiplier

The Mental transform feature is triggered when you land a golden Spider symbol on reel 2 or 4. The Spider transforms into xWays, xSplit, xNudge, or Dead Patient symbols.

Scatters will trigger one of the 3 Free Spins rounds.

  • Autopsy spins are awarded for landing Scorpion symbols. Sticky fire frames are in play here.

  • Lobotomy spins are awarded for 3 Scorpions and one Spider symbol. This starts the Dead Patient collection mechanism.

  • Mental Free Spins is triggered by 3 Scorpions and two Spiders. Spider transformations and increasing Dead multipliers come with this option.


Mental’s RTP is 96.08% in the base game, however, it increases with the different features. This is a very volatile game so compared to other slot games it doesn’t pay out often.


If you are into horror games, you should try out Mental. This high-volatility game comes with a very high maximum win, and it offers lots of special features as well as a unique game mechanism.
