Mental II Slot Review (Nolimit City) and Free Demo - Max win 99,999x

Review Grade:
(8.7/10)
Reviewed on March 20, 2025

If you thought Mental was wild, Mental II takes madness to a whole new level. With a terrifyingly high max win of 99,999x your bet, xMental™ features, cascading symbols, and unpredictable reel transformations, this slot is a high-volatility nightmare designed for the bravest players. Released by Nolimit City, Mental II is a horror-fueled descent into the darkest corners of the human mind, where patients, deadly multipliers, and relentless bonus rounds keep the action terrifyingly unpredictable.

Slot Overview

Mental II is built on a 3-2-3-2-3 reel layout, providing a unique, shifting reel dynamic that works hand-in-hand with its chaos-fueled mechanics. With a 96.06% RTP, an insane volatility rating, and a hit frequency of 31.41%, wins come in unpredictable bursts, but when they land, they can reach astronomical heights.


With its unpredictable symbol-splitting mechanics, multiplier-stacking madness, and a terrifying asylum theme, Mental II is designed for high-risk, high-reward players.

Key Features and Mechanics

Fire Frames & Fire Reels: Symbol Chaos Begins

  1. Fire Frames: Randomly, 1 to 13 reel positions may ignite, causing any symbol that lands inside them to split into two.
  2. Fire Reels: A more extreme version, 1 to 5 entire reels can become Fire Reels, where symbols split into three parts for even bigger wins.

Dead Patients: Multiplier Madness

  1. Activates when 2 Dead Patient symbols land.
  2. Reveals a random multiplier between x5 and x9,999.
  3. Multiplier reflects the symbol count on that reel, making this one of the most volatile features in the game.

xHole™: A Bottomless Pit of Insanity

  1. Activates when xHole™ lands in a Fire Frame or Fire Reel on the second position of the third reel.
  2. Sucks in symbols from the reels, scattering them to random positions with size multipliers of x2, x4, or x8.
  3. If it lands outside a Fire Frame, it doesn’t activate, keeping its power as unpredictable as the game itself.

xMental™: The Most Chaotic Feature Yet

  1. Activates when xMental™ lands in a Fire Frame or Fire Reel anywhere on the reel area.
  2. Triggers an extra spin, where:
  3. All reel positions become Fire Frames.
  4. Enhancer Cells reveal xWays®, xNudge® Wilds, or xSplit® symbols.
  5. A chance to trigger xHole™ for even crazier results.

Mental Transform: Shapeshifting Symbols

  1. When a Disembodied Scatter lands on reel 2 or 4, it transforms into one of the following symbols:
  2. xWays®
  3. xSplit®
  4. Dead Patient
  5. Wild
  6. Regular Patient Symbol

Three Levels of Free Spins – Welcome to the Asylum

Bloodletting Spins: The First Descent

  1. Triggered by landing 3 Cognitive Scatters.
  2. Fire Frames and Fire Reels become sticky, remaining for the duration of the bonus round.
  3. Landing a Disembodied Scatter upgrades the round to Surgery Spins.

Surgery Spins: The Madness Escalates

  1. Upgrades from Bloodletting Spins when a Disembodied Scatter lands.
  2. Dead Multipliers are collected and stored, transferring to Patient symbols for massive wins.
  3. Landing another Disembodied Scatter upgrades to ExperiMENTAL Spins.

ExperiMENTAL Spins: The Ultimate Horror Show

  1. The final level of free spins—Dead Multipliers never decrease and keep stacking.
  2. Every spin is a potential max win with Patient multipliers growing indefinitely.

xBet™ & Feature Buys: Pay for Your Insanity

For those who don’t want to wait, Mental II offers four levels of Nolimit Boosters:

  1. xBet™ (1.4x bet cost) – Guarantees a Cognitive Scatter on reel 1.
  2. Fire Frames (6x bet cost) – Ensures Fire Frames on all reel positions.
  3. xHole™ Activation (99x bet cost) – Triggers the xHole™ mechanic instantly.
  4. xMental™ Activation (3,200x bet cost) – Guarantees xMental™ in play.

And for the ultimate gamble:

  1. God Mode (6,666x bet cost)Guarantees xGod® symbols, giving you a direct shot at the 99,999x max win.

Max Win & Payouts

The holy grail of Mental II is its 99,999x max win. This can be achieved in two ways:

  1. Through standard gameplay, by hitting an insane combination of xMental™, Dead Patients, and bonus rounds.
  2. Instantly triggering the max win by landing xGod® symbols on all reels.

Theme & Visuals – A Horrific Descent into Madness

Mental II is disturbing, unsettling, and utterly unique. The game’s grim asylum setting, flickering visuals, and erratic animations create a deeply immersive horror experience. Every spin feels like a trip through a deranged mind, filled with unexpected twists, eerie sound effects, and shocking mechanics.

Final Verdict

Mental II is not just a slot; it's an experience—one that pushes the boundaries of what an online slot can be. With insane volatility, unpredictable reel transformations, and features that intertwine in a way that feels completely chaotic yet incredibly calculated, this game is for those who seek the ultimate high-stakes thrill.

Nolimit City has taken the foundation of the original Mental slot and amplified it to terrifying new heights. The introduction of xMental™, xHole™, Fire Frames, and Dead Patients multipliers adds layers of unpredictability, making each spin feel like you're one step away from either madness or a massive payout. The cascading mechanics and dynamic ways to win mean that no two spins are ever the same, giving this slot an almost roguelike feel, where every attempt has the potential to be wildly different from the last.

The three-tiered bonus system is one of the most brilliant aspects of Mental II. It ensures that progression feels rewarding, with Bloodletting Spins introducing players to the madness, Surgery Spins ramping up multipliers, and ExperiMENTAL Spins creating a scenario where every spin is an all-or-nothing showdown. Dead Multipliers that persist and stack make this bonus round incredibly dangerous in the best way possible.

Of course, this level of volatility comes with a cost. The high risk means that players need to be prepared for long dry spells, and while the max win of 99,999x is absolutely mind-blowing, it's a rare beast to capture. The Bonus Buy options, while tempting, are expensive, especially the 6,666x bet God Mode that guarantees the ultimate feature. If you're a casual player or prefer steady wins, this might not be your ideal slot.

But for those who love extreme slots, who crave the highest risk, highest reward gameplay, Mental II is a masterpiece. The unpredictability, the sheer brutality of its multipliers, and the potential for life-changing wins make it one of the most exhilarating releases of the year. Whether you're chasing Dead Multipliers, triggering xMental™, or stepping into the chaos of ExperiMENTAL Spins, every moment in this game is charged with suspense.

At Spinaspin, we admire slots that push boundaries, break expectations, and redefine what gambling experiences can be. Mental II does exactly that—and for those brave enough to handle it, this could be one of the most thrilling slots ever made. If you’re ready to embrace the madness, step inside the asylum and see if you can escape with your sanity—and a 99,999x payout!
