The Mental 2 Slot Game
The original slot dove deep into the lowest possible level of madness, and would have left the weak-hearted shutting down their devices. But you know things are about to get even more gruesome when Nolimit City starts the game with a “disturbing visuals and intense graphic content” warning.
Mental 2 takes you to meet a murderous, deranged daughter who butchered her parents. Now, she’s been shipped to an unforgiving asylum designated for people with extreme and illogical behaviour.
The Splash screen introduces you to a bloody scene. Continuing past the screen, you enter a hallway illuminated by a creepy yellowish light. Terrifying scribbles and scratches cover the walls, while gory, bloody messages appear occasionally.
In summary, neither the visuals nor the sounds are pleasant. I’m even wondering whether it’ll appeal to every audience.
Symbols and Payouts
This video slot puts to effect 10 regular symbols split into two ranks. They randomly land on the 3-2-3-2-3 gameboard after a successful spin and could unlock a win. And yes, they are curated to fit the theme.
With 108 ways by default, you hit a winning combo when 3 or more identical symbols land on adjacent reels from the leftmost reel to the right. Then, you evaluate the payout by multiplying the paytable value by the selected bet.
The low-ranking symbols in Mental 2 are the Foot, Spine, Ribcage, Foetus, and Skull Skeletons. They award 0.1-0.5x, 0.15-0.55x, 0.2-0.6x, 0.25-0.7x, and 0.3-0.75x the stake for 3+ of the same.
Meanwhile, the higher-paying symbols include 5 Patients with sombre faces. However, they pay between 0.3x and 2.5x the bet, slightly higher than the low-valued symbols.
This slot also has Wild symbols that substitute for all the regular symbols when completing winning combinations.
Mental 2 Slot Bonus Features
I recommend taking a much-needed water break before exploring the network of features here. Done? Let’s get into them!
Fire Frames & Fire Reels
1 to 13 reel positions may randomly become a Fire Frame in the Mental 2 base game. Any symbol that lands in the Fire Frame splits into 2 parts. Further, 1 to 5 reel positions may turn into a Fire Reel during the base game. Any symbol that lands in the Fire Reel splits into 3 parts.

Dead Patients
This feature starts when 2+ Dead Patients appear. One of the Patient symbols will receive between 5x and 9999x multipliers, reflecting the reel’s symbol count.

Enhancer Cells
These rest at the bottom of columns 2-4. The more the Fire Frames, the more the activated Enhancer Cells:
- 4 Fire Frames activate the Reel 2 Enhancer Cell.
- 6 Fire Frames activate the Reel 2 and 4 Enhancer Cells.
- 8 Fire Frames activate all the Enhancer Cells.
A Fire Reel equals 2 or 3 Fire Frames for the Enhancer Cell activation, depending on the Mental 2 reel it’s on. Every Enhancer Cell may reveal:
- Regular wild symbol.
- An xSplit - splits and doubles a symbol on each of the other columns and splits itself into two.
- xNudge Wild - always nudges to be fully visible on the reel, with every nudging step increasing the multiplier by +1x. Several wild multipliers are additive, and when an xSplit splits an xNudge Wild, the multiplier on the latter increases by +1x.
- One of the 5 Patient symbols.
- xWays - unveils 3 identical symbols and expands the reel height. Multiple xWays symbols reveal the same symbol.
xHole
This feature starts when the xHole symbol lands in a Fire Frame or a Fire Reel on the 3rd reel’s 2nd position. The regular paying symbols and the wild are randomly scattered, and their current sizes are multiplied by 2x, 4x, or 8x.
In the case of an xNudge Wild, it only modifies its win multiplier. Then, the xHole becomes wild. Winning symbols before the xHole suck return to their positions.
xMental
It starts when the xMental symbol appears in a Fire Reel or Fire Frame on the Mental 2 reels. It triggers an extra spin with the following features:
- All reel positions receive Fire Frames.
- Enhancers reveal xNudge Wild, xWays, or xSplit.
- Potentially triggering the xHole.
However, the feature doesn’t start when an active xMental symbol lands during a bonus trigger.
Mental Transform
This feature starts when you land the Disembodied scatter on the 2nd or 4th reels. The Disembodied scatters transform into an xWays, Dead Patient, xSplit, Wild, or Patient symbol.
Scatters
The Cognitive scatters only hit on the odd-numbered Mental 2 reels, while the Disembodied scatters appear on the even-numbered ones. Landing 3 Cognitive scatters trigger 8 Bloodletting Spins, 3 Cognitive scatters + 1 Disembodied scatter trigger 9 Surgery Spins, and 3 Cognitive Scatters + 2 Disembodied scatters trigger 10 Experimental Spins.
Every scatter in a Fire Frame or a Fire Reel awards +1 and +2 free spins, respectively.
Bloodletting Spins
The Fire Frames and Fire Reels remain sticky throughout the bonus. Land 1 Disembodied scatter to receive a +1 spin and upgrade the remaining spins to Surgery spins. Meanwhile, 2 Disembodied scatters award +2 spins and upgrade the feature to Experimental spins.

Surgery Spins
Apart from the Bloodletting spins, the Disembodied symbol gets sticky and activates the Mental Transform feature per Mental 2 spin. The highest ‘Multiplier’ from every Dead Patient symbol accumulates with its ‘Count’. The count is the number of particular Patient symbols revealed.
After the collection, the Dead multipliers are transferred to their corresponding Patient symbols based on the Count when a new collected Patient symbol appears. Whenever a Dead multiplier transfers to a Patient symbol, the count reduces by 1. However, the Dead multiplier doesn’t transfer to symbols revealed by the Dead Patient symbol.
Land 1 new Disembodied scatter to upgrade the bonus to Experimental Spins and receive a +1 spin.
Experimental Spins
Above the Surgery spins features, both Disembodied scatters get sticky and trigger the Mental Transform in every Mental 2 spin. The Dead multiplier count for the Patient symbols doesn’t decrease after being transferred to a Patient symbol. Instead, it keeps building up.

Nolimit Booster
Spend 1.4x bet for a guaranteed Cognitive scatter on reel one and 6x bet for guaranteed Fire Frames on all reel positions. Then, for 99x bet, the xHole is guaranteed to activate, and for 3,200x bet, the xMental is guaranteed to start.
God Mode
If your bankroll can support spending 6,666x bet, you can chase the maximum win by landing the xGod symbol on every Mental 2 reel.

Bonus Buy
For the final stretch, you can instantly buy 8-14 Bloodbetting Spins for 100x bet, 9-17 Surgery Spins for 250x the stake, and 10-20 Experimental Spins for 1,800x bet. The slot also has a Lucky Draw option for 330x stake.
How to Win at Mental 2 Slot
Don’t be spooked by the warning message. This game has 5 conventional reels configured into 3-2-3-2-3 rows, with 108 ways that can increase during the features, especially the splitting ones.
A win happens when you land 3+ identical symbols on adjacent reels from the outermost left side to the right.
As for the bets, Mental 2 lets you wager between €0.20 and €100. Gamble every spin individually using the Spin button or several preselected rounds automatically using the Autoplay function.
The Turbo function speeds up the reels, while the Menu function leads you to the paytable and game rules.

Mental 2 RTP & Volatility
The extreme volatility could pose a significant risk to your remaining playing balance. However, its 31.41% hit frequency and 96.06% RTP are decent. Finally, its maximum win tops at an unimaginable 99,999x the stake!
The Final Thoughts
Whew! That was a lot to cover in one take; I’d have dusted myself up like someone who has explored the Library of Congress. But it doesn’t shock me, as it’s expected of Nolimit City, especially since the studio has been keeping a low profile for its games’ features recently.
Like the original Mental slot, Mental 2 requires a strong stomach to endure its unsettling atmosphere. The gory visuals and the unpleasant sounds and effects ensure that if it’s not the high volatility that will kick you out of the game, you’ll have no option but to shut your device down in fear of being the deranged girl’s next target.
Yet, the gameplay has many ways of keeping you glued to the game in the name of its features. There are so many, ranging from Enhancer Reels to numerous special symbols and free spins, among others, you’d have to read this review in its entirety to grasp them all.
However, the game may be complex, especially for first-timers, thanks to its many features. Fortunately, the free demo here should prepare you for the real-money experience. And, if you’re lucky, you could be the very special person waiting to pocket the staggering win cap!
