Nolimit City is known for slots that like to push the boundaries, but with Mental, they delve deeper into the darkness than ever before at non GamStop casinos. Mental launched in August 2021 and has since amassed a loyal fan base. Everything about this game feels distorted, from the flickering lights to the sinister soundtrack. Mental is unnerving, brutal, and packed with features that fly in every direction. The game sets the bar high and the atmosphere even higher. This isn’t a slot you’ll just relax and enjoy for a few spins — it’s the kind of experience often highlighted in a step-by-step credit card casino guide off GamStop. Mental grabs you and won’t let go.
Advantages and Disadvantages of Mental
The Mental online slot machine has the following advantages and disadvantages:
Advantages
• Intense atmosphere and theme
• Original features
• High multipliers
Disadvantages
• Extremely high volatility, so unpredictable
• Complex gameplay
Gameplay and Mechanics of Mental Slot
Mental is played on a five-reel grid in a 3-2-3-2-3 layout. The game is available at almost any modern online casino without GamStop. There are 108 ways to win at the base, but this number can increase significantly when the reels expand to as many as 20 rows. You win when three or more matching symbols appear on adjacent reels, starting from the left.
The RTP is 96.08%. As with almost all Nolimit City games, the volatility is sky-high. The provider calls it “Extreme,” and that’s no exaggeration. Long periods of silence can suddenly turn into complete chaos. Betting ranges from €0.20 to €100 per spin.
Mental payouts and symbols
The atmosphere intensifies as soon as you see the symbols appear. The low-value symbols consist of body parts: skeletal hands, kidneys, hearts, brains, and eyes. For the higher payouts, you’ll encounter five unnamed patients, designated Patients 1 through 5 at non GamStop casinos. Five of a kind yield between 150 and 500 times your stake when playing with the maximum bet of €100 per spin.
Here is the payout table:
| Symbols | Value |
|---|---|
| 5 identical | — |
| Patient 1 | 500 |
| Patient 2 | 375 |
| Patient 3 | 250 |
| Patient 4 | 200 |
| Patient 5 | 150 |
| Eye | 125 |
| Brain | 115 |
| Heart | 110 |
| Kidneys | 105 |
| Skeleton hand | 100 |
Bonus features of Mental
Mental offers a complete storm of insane game mechanics. We felt a bit overwhelmed at first, but there’s still logic to the chaos at non GamStop casinos. You’ll encounter Fire Frames, Enhancer Cells, Dead Patients, and three types of free spins.
Fire Frames
In the base game, the flames already start dancing. Each spin, one to 13 random positions are set ablaze with Fire Frames. A symbol falling within such a frame splits in two.
Dead Patient feature
Then there’s the Dead Patient feature. It sounds like you’d rather avoid it, but you’ll want to see it. Two Dead Patient symbols activate this feature, revealing one of the premium patients, along with a random multiplier that climbs to an absurd 9,999 x. It’s not your winnings that are multiplied, but the number of symbols on the reel. It’s a strange logic, but it works.
Enhancer Cells
Hidden at the bottom of reels two and four are the Enhancer Cells, a kind of hidden syringe that also appears in the San Quentin xWays slot . They only become active when four or six Fire Frames land on the corresponding reel. When this happens, you’ll receive a bonus effect that can turn everything upside down.
The Enhancer Cells activate the following effects:
• A wild symbol appears.
• One of the five patient symbols is revealed.
• A standard Dead Patient symbol will appear.
• xWays: Three identical symbols are displayed.
• xSplit: One symbol on each reel splits in two and turns itself into two wilds.
• xNudge Wild: A symbol is pushed forward and each nudge increases the win multiplier by 1. If multiple xNudge Wilds are active, the multipliers stack for even bigger wins.
If a spin symbol appears on reels two or four, it activates the Mental Transform feature. This turns spins into a special symbol (wild, Dead Patient, xWays, xSplit).
Autopsy Free Spins
The first free spins are the eight Autopsy Free Spins at non GamStop casinos. These are activated when you land three scorpion symbols on reels 1, 3, and 5. Each scorpion symbol that lands within a Fire Frame awards an extra spin. During this bonus round, up to five random positions are assigned a Fire Frame, which then remain fixed for the duration of the feature. If you land a spider symbol during this round, you can upgrade to the Lobotomy Free Spins.
Lobotomy Free Spins
Lobotomy Free Spins is activated with three scorpions and one spider symbol in the base game. You then receive nine spins. The same rules apply as Autopsy Spins, but with an added bonus: all spider symbols that appear become sticky and trigger the Mental Transformations on every spin.
There’s also the Dead Multiplier rule, where the highest multiplier from the Dead symbols is collected and applied to new patient symbols. Landing two spider symbols during this round advances you to Mental Free Spins.
Mental Free Spins
The most lucrative free spins are the Mental Free Spins. You activate these when you collect three scorpion symbols and two spider symbols in the base game. You get 10 spins, and the big difference is that both spider symbols are sticky and activate the Mental Transformations on every spin. Furthermore, the Dead Multiplier counter remains infinite, meaning the multiplier is applied again and again without decreasing. This makes this feature the ultimate chance for big wins.
Conclusion
With this slot, Nolimit City once again proves they dare to experiment and push boundaries. The grim and oppressive atmosphere, combined with the many features, will keep you on the edge of your seat the entire time.
Mental isn’t like many other slots. The unexpected transformations and dynamic symbols remind us of the chain reactions of Reactoonz , but the theme is much darker.
Mental’s volatility is sky-high, and it’s evident in everything. Sometimes nothing much happens at non GamStop casinos, but suddenly explosive moments follow one another where everything seems to happen at once. Mental is a dark, complex, and intense game that will challenge your mind and test your patience. If you enjoy a challenge, you’ll undoubtedly have a blast with Mental.
