Mental Review

Nolimit City flips their gaming settings to dark mode with this release from August 2021. Set in the bowels of a sanatorium, Mental is a video slot incarnation of madness and mayhem with an intensely sinister style.

Set in an asylum with a twist, Mental seems to be part halfway house for the institutionally insane and part morgue possessed by the undead – a charming combination for a slot theme. Will this slot, as the title suggests, be one of deranged delight or more than a little non-compos mentis? Let’s take a look.

Mental Free Spins

With a total of three free spin rounds, Mental brings you more chances to pouch cash wins. Now let’s break them down:

  • The Autopsy Free Spins round is triggered by landing three scorpion symbols anywhere on the grid. Autopsy Free Spins dictate that all fire frames are sticky throughout the round and bring you a free spins feature with the potential to ignite big wins.
  • Lobotomy Free Spins are unlocked when you land three scorpion symbols and a spider symbol in a single spin. Not to be outdone by Autopsy Free Spins, Lobotomy Free Spins enable sticky fire frames and spider symbols throughout.
  • Land two spider symbols and three scorpions and you are admitted to the Mental Free Spins round. With the combined features of Autopsy Free Spins and Lobotomy Free Spins, Mental Free Spins are a bonus round mashup where the multipliers increase perpetually.

More Features & Wager Limits

Further freaky features include Dead Patient multipliers – spin two of these symbols and a random multiplier is unlocked with a minimum of 5x all the way up to a deranged 9,999x.

Enhancer Cells add further feature fun and incorporate the Nolimit City trademarked xWay, xNudge, and xSplit mechanics.

With a minimum and maximum bet of $0.20 and $100 respectively, playable across 108 paylines, high volatility Mental comes with an RTP of 96.06% and a top win potential of a numerically nefarious 66,666x.

Mental Slot Design & Music

The typographical design choice for Mental is fully-fledged horror movie-style and the in-game design obediently follows suit. The music is mysteriously macabre; making for an unsettling audio outing, keeping you on the edge of your seat for potentially big wins or perhaps something slightly more sinister.

Symbols consisting of pulsating brains, anatomical hearts and kidneys that have seen better days – a full-service fear package, Mental is a classic example of designers running with a theme and leaving little to the imagination of the mainly terrified audience.

Review Summary

Kudos to Nolimit City for creating such a disturbing slot. While other horror titles toy with a playful scary movie style aesthetic, Mental is in a league of its own when it comes to providing imagery and atmosphere so ardently terrifying that it could push you over the edge.

Detractors cite Mental as a game that’s too sinister, overly dark and wildly grotesque. They’re completely right of course, but this is the exact response a slot of this nature hopes to elicit. With shock factor credentials firmly in place, Mental is a gaming outing that is not for those of a sensitive nature. This slot is insane.
