The provider has chosen a very delicate topic for a slot theme, but they have done it well. You almost cannot find such a theme in any other portfolio. The design is also very unique, but we’ll have a word about that later in the review. So, let’s see what this slot can bring to us.

About Mental Slot

The Mental slot comes from the portfolio of NoLimit City, a provider with ten years of experience. They probably looked to be very unique when they were looking for a slot theme, so they chose to name the slot Mental. The game comes with 108 active paylines.

Three features and three kinds of free spins are in play at this slot. Big multipliers can also play their part here, as part of the features. For instance, in the Dead Patient feature, it can come to x9999. The maximum winning potential of this game played on 5 reels, is up to 66,666x the stake. 

Design, Symbols and Graphics

As a spooky slot, this game has an unusual design. Some weird brown-beige colour dominates the reels, while on them we see some spooky symbols. Skeleton head, an eye, other body organs, arm bones and other similar symbols make the theme what it is - spooky. The dark background and the yellow light from the lightbulb above the reels are what complements the whole idea.

Gameplay and Features on Mental Slot

As we mentioned, at the Mental slot we have several features. These are Dead Patients, Enhancer Cells, Transforming Symbols and three kinds of Free Spins - Autopsy, Lobotomy and Mental. The maximum payout in the bonus is 66,666x the stake.

Dead Patients Feature

If two of the Dead Patients Symbols appear on the grid, a random multiplier from x5 up to x9999 can be applied to the game. 

Enhancer Cells Feature

The Enhancer Cells are like boosters to the reels, which can help you land wins more easily. Such enhancers are xWays, xNudges and xSplits.

Transforming Symbols Feature

If a spider lands anywhere on the grid, symbols will transform to help you have a better overall winning potential.

Free Spins Feature

This game has three kinds of free spins:

  • Autopsy Free Spins - landing three scorpion symbols on the grid triggers the bonus feature. While it lasts, Fire Frames are sticky. This means the winning ways are enhanced at this time.
  • Lobotomy Free Spins - Three scorpion symbols and a spider activate Lobotomy Spins. The Fire Frames here are active, and the spyder symbol becomes sticky. The feature is spiced up with Dead Multiplier.
  • Mental Free Spins - Three scorpions and two spider symbols trigger the feature. Here you get everything as in the previous two rounds, only the Dead Multiplier doesn’t reset.
