Nolimit City is once again pushing boundaries with the launch of Mental II, the much-awaited sequel to its highly popular online slot, Mental. Released on March 25th, 2025, Mental II revisits the unsettling psychiatric asylum theme that made the original slot famous. Retaining the dark atmosphere players loved, the game introduces fresh gameplay elements and new features, further amplifying the intensity and volatility.

A darker journey into madness:

Continuing Nolimit City’s tradition of bold and provocative slot themes, Mental II returns players to a bleak asylum environment depicted through gritty sepia-toned visuals and unnerving sounds. Within this disturbing setting, the story revolves around a disturbed young woman, institutionalized for murdering her parents. The slot graphically portrays the sinister and unsettling aspects of her incarceration, creating an immersive yet grim gaming experience.

Mental II preserves the original’s unconventional 3-2-3-2-3 reel structure, initially offering 108 ways to win. However, due to the game’s multiple innovative mechanics, the ways to win significantly increase during play. Symbols are divided between five lower-paying skeletal images and five higher-paying patient symbols, all designed to maintain the eerie thematic consistency.

Innovative mechanics and explosive features:

Among the most notable features returning from Nolimit City’s repertoire are the iconic xMechanics such as xWays, xSplit, and xNudge. Newer features like xHole, originally from Kenneth Must Die, and the debuting xMental mechanic add layers of complexity and excitement to the gameplay. These mechanics dramatically influence the reels by splitting symbols, enhancing multipliers, or expanding symbol counts, vastly improving potential payouts.

Fire remains a core gameplay element, and the slot enhances it with two main mechanics known as Fire Frames and Fire Reels. At random, positions on the reels become engulfed in flames, causing symbols landing within these burning spaces to split, thus increasing the number of potential winning combinations. Fire Frames split affected symbols into two, while entire reels that become Fire Reels can split each symbol into three.

The Enhancer Cells, located beneath the middle reels, are activated progressively as more Fire Frames appear. Unlocking these cells can grant various special symbols or powerful modifiers like wilds, xWays, and xNudge wilds, substantially amplifying wins and enhancing overall volatility.

Mental II further escalates the experience with the new xMental feature, triggered when an xMental symbol lands within a Fire Frame or Fire Reel. When activated, this mechanic triggers a respin where every reel position catches fire simultaneously, and multiple special symbols can appear simultaneously, potentially triggering massive payouts through an explosive series of events.

Mental II offers three tiers of bonus rounds activated by Cognitive and Disembodied scatter symbols. Bloodletting Spins start with eight free spins featuring sticky Fire Frames and Fire Reels, increasing chances for bigger wins. Landing additional Disembodied scatters upgrades these spins into more lucrative Surgery Spins, which not only offer sticky transformative symbols but also a unique Dead Multiplier system. Dead Multipliers collected during spins transfer multipliers onto specific symbols, potentially leading to substantial wins.

The highest level, ExperiMENTAL Spins, offers all previous bonuses but with a twist: Dead Multipliers never decrease, continually building up for even higher payout potential. Additionally, a Mental Transform feature activates whenever Disembodied scatters land on specific reels, turning them into premium symbols or game-changing modifiers, adding yet another thrilling layer to the gameplay.

Exceptional payout potential and bonus buys:

Nolimit City classifies Mental II’s volatility as “Insane,” the highest level it offers. Reflecting this extreme volatility, players can achieve an extraordinary maximum payout of 99,999 times their stake. The slot features a return-to-player (RTP) rate of 96.06%, aligning with industry norms for highly volatile slots. This massive win is attainable through the rare xGod feature, which triggers instantly when an xGod symbol appears on every reel simultaneously.

Players seeking immediate access to special features have numerous bonus buy options at their disposal. These include purchasing Bloodletting, Surgery, or ExperiMENTAL Spins directly at escalating costs. For those seeking the ultimate adrenaline rush, the premium God Mode is available for a significant investment, offering one immediate chance to hit the maximum payout.

Per Lindheimer, Nolimit City’s Head of Product, expressed excitement in the company’s press release, stating: “What can I say about Mental II besides the fact that we’ve poured blood, sweat, and probably too much blood into this beast. xMental is a mechanic we’ve been cooking up for a while, and trust me—it’s absolutely mental! We wanted to take everything that made Mental great and push it even further. No compromises ”
