Mental 2 Slot Review review

Mad in every aspect

We’re huge fans of the Mental series, and Mental 2 looks promising with its features.

Symbols & payouts of Mental 2

Like its previous iteration, the symbols in Mental 2 are based on patients at an asylum. Their payouts vary according to the number of symbols in a payline.

What special features does Mental 2 have?

Mental 2 is one of the most complete slots on the market in terms of features. The game has over 10 resources to help players reach the maximum win, including three free spin bonus rounds. Keep reading this Mental 2 review to learn more:

Fire Frames & Fire Reels

On any spin, up to 13 positions on the reels can turn into a Fire Frame, splitting symbols that land inside. In addition, up to five reels can become Fire Reels, which split symbols that land inside it into three parts.

Dead Patients

You can trigger this feature whenever you land two Dead Patient symbols. It reveals Patient Symbols with a 5x, 10x, 15x, 30x, 50x, 100x, 200x, 500x, 1,000x, or 9,999x multiplier.

Enhancer Cells

Enhancer Cells appear at the bottom of the second, third, and fourth reels. They’re activated based on the number of Fire Frames that appear on the reels.

4 Fire Frames	Reel 2
6 Fire Frames	Reels 2 and 4
8 Fire Frames	Reels, 2, 3, and 4

Enhancer Cells can reveal one of the following symbols:

Wild – A standard wild symbol.
xSplit – Splits and doubles one symbol in each reel and splits itself into two wilds.
xNudge Wild – These symbols always nudge to become fully visible, increasing the multiplier by one with every position moved.
Patient Symbol – One of five Patient Symbols.
xWays – Reveals three characters of the same kind and expands the reel.

xHole Feature

To activate this resource, you must land an xHole symbol on the second position of the third reel when it’s a Fire Frame or a Fire Reel. Regular symbols and wilds are moved to random positions, and their payouts are multiplied by 2x, 4x, or 8x.

xMental Feature

You can trigger this feature by landing an xMental symbol inside a Fire Frame or Fire Reel. It gives players an extra spin with all reel positions containing Fire Frames, Cell Enhancers that reveal xWays, xNudge Wild, or xSplit symbols, and a change of triggering xHole.

Mental Transform

Mental Transform is triggered by getting Disembodied Scatters on the second or fourth reels, which transform into xWays, xSplit, Dead Patient, Wild, or Patient Symbols.

Free spins

We also looked into the game’s free spin rounds while writing this Mental 2 review. Here’s how they work:

Bloodletting Spins	Unlocked by landing three Cognitive Scatters. Fire Frames and Fire Reels remain sticky while the round is active. Getting one Disembodied Scatter upgrades the feature to Surgery Spins and rewards players with one spin. Getting two Disembodied Scatters upgrades the feature to ExperiMENTAL Spins and awards two spins.
Surgery Spins	Unlocked with three Cognitive Scatters and one Disembodied Scatter. Includes sticky Fire Frames/Reels and the Mental Transform feature on every spin. Multipliers from Dead Patient symbols are collected in a special meter. Getting one Disembodied Symbol upgrades the feature to ExperiMENTAL Spins and awards one spin.
ExperiMENTAL Spins	Same as the other free spins bonuses, except it includes two sticky Disembodied Symbols and multipliers don’t decrease when transferred to Patient symbols.

Highly entertaining features

The game is packed with fun bonuses. However, they might be confusing for beginners.

Graphics & sound of the Mental 2 slot

Mental 2 Slot Game Graphics UK — This slot game is based in an asylum, featuring spooky graphics and an eery soundtrack.

In our opinion, the Mental 2 slot perfectly showcases what Nolimit City is capable of, both in terms of graphics and sounds. The game has a deranged look that works incredibly well with the complex bonus features.

Pros & cons of the Mental 2 slot

Playing Mental 2 has several advantages, especially if you’re someone who loves slots with crazy features, like xMental and ExperiMENTAL Spins. On the flip side, it’s one of the most volatile casino games we’ve ever seen, and the bonuses can be hard to understand at first.

Pros	Cons
✅ Top prize of 99,999x your wager	❌ Extremely volatile slot
✅ Exciting bonuses with high payouts	❌ Features can be difficult to understand
✅ Fair RTP percentage of 96.06%	❌ The minimum bet is £0.20
✅ Maximum bet of £100

Pay attention to the high volatility

High volatility slots aren’t exactly beginner-friendly. It may take some time until you land a win.

Is the Mental 2 slot as wild as it looks?

Mental 2 is twice as unhinged as its predecessor. It has crazier features, a higher maximum win, and a creepier look. The result is a fast-paced slot that will definitely give you the chills. However, it’s too volatile for our taste. Overall, our rating with this Mental 2 review is 9/10.
