Mental Slot Demo

NoLimit City’s Mental slot game takes players into the depths of a chilling and macabre setting, a turn-of-the-century lunatic asylum, as they were known then.

With features like Autopsy and Lobotomy, this slot offers a truly bleak and eerie gaming experience. Although they are known for unconventional themes, this slot is really pushing the boundaries, and definitely will not appeal to all. 

Set on a 3×5 grid with 108 winning ways, Mental offers additional winning opportunities through xWays and xSplit features.

RTP varies from 96.06% to 94.08%, so check what’s on offer before playing.

The game is rated 10/10 for volatility, with a massive top prize of 66,666x.

Game Features

Fire Frames

On each spin, 1 to 13 positions are randomly surrounded by flames, known as Fire Frames. Any symbol landing within a Fire Frame splits into two parts, potentially creating more winning combinations.

Dead Patients

The ominously titled Dead Patient feature triggers when 2 Dead Patient symbols hit.

It reveals one of the premium patient symbols with a random multiplier, ranging from x5 to a staggering x9,999. The multiplier value corresponds to the number of that symbol on the reel, rather than acting as a win multiplier.

Enhancer Cells

Positioned at the bottom of reels 2 and 4, the Enhancer Cells are activated with 4 or 6 Fire Frames, respectively. When active, Enhancer Cells reveal one of several effects, including a wild symbol, one of the five patient symbols, a regular Dead Patient symbol, xWays (revealing three identical symbols), or xSplit (splits one symbol into two, then splits itself into two wilds).

Mental Transformations

Landing spider symbols on reel 2 or 4 triggers the Mental Transform feature.

Spiders transform into various symbols, including xWays, xSplit, Dead Patient, Wild, or Patient symbols, potentially leading to significant wins.

Free Spins Bonuses:

Autopsy Free Spins

Triggered by landing 3 Scorpion symbols on reels 1, 3, and 5. Each Scorpion symbol landing in a Fire Frame awards an additional spin. Up to 5 positions are randomly given a Fire Frame during this bonus game, with the frames remaining sticky throughout the feature.

It is possible to upgrade Autopsy Spins to Lobotomy Spins by landing a Spider Symbol.

Lobotomy Free Spins

Awarded by landing 3 Scorpion symbols and 1 Spider symbol in the base game.

Similar to Autopsy Spins, but with the addition of sticky spider symbols that trigger Mental Transformations on each spin. Features Dead Multiplier rules, where the highest multiplier value from Dead Symbols is collected and applied to new Patient symbols.

Mental Free Spins

The most lucrative bonus round is triggered by landing 3 Scorpion symbols and 2 Spider symbols in the base game. Features sticky spider symbols and enhanced Dead Multiplier rules, offering potentially massive wins.
