Mental 2 Slot Review: xGod, Fire Reels and a 99,999x Max Win

Mental 2 Slot Review: A Sequel That Earns Its Place

This Mental 2 slot review covers the March 2025 follow-up to one of Nolimit City's most respected games. Sequels often play it safe. Mental 2 does the opposite, keeping the core ideas of the original while adding new xMechanics, a stronger free spins ladder and a 99,999x max win that is half as high again as the first game.

It is a harsh, demanding slot, and Nolimit City rates its volatility at the very top of its scale. It is also one of the most rewarding high-risk games released in recent years, which is exactly the profile ReelRadar favours.

Because there is so much going on, we strongly suggest starting with the Mental 2 demo on ReelRadar. Learning which symbols matter, and where, makes the real-money experience far less confusing.

Grid, Theme and Base Game

The grid uses a 3-2-3-2-3 shape, giving 108 ways to win before any modifiers kick in. Cognitive Scatters land only on reels 1, 3 and 5, while Disembodied Scatters land only on the shorter reels 2 and 4. That split matters, because each scatter type plays a different role in the bonus.

The asylum horror theme returns and is, if anything, more graphic than before. This is clearly an adults-only game, and players who dislike gore should look elsewhere.

Nolimit City lists a hit frequency of 31.41%. As with the original, most base wins are small, and the excitement comes from modifiers stacking on the same spin.

Bets run from €0.20 to €100 per spin according to the provider, which gives high rollers more room than the first game did. Whatever your stake, size it so that a few hundred spins without a bonus will not end your session early.

Fire Frames, Fire Reels and Enhancer Cells

Each spin can turn between 1 and 13 random positions into Fire Frames, and a symbol landing in one splits into two. Fire Reels are the bigger version. Between one and five random reels can become Fire Reels, and any symbol landing on one splits into three.

Those frames also power the Enhancer Cells under reels 2, 3 and 4. Four Fire Frames open the cell on reel 2, six open reels 2 and 4, and eight open all three. A Fire Reel counts as two or three frames depending on its size. Opened cells can reveal a Wild, xSplit, an xNudge Wild, a Patient symbol or xWays.

Dead Patients return too. Two of them trigger a reveal that gives one Patient symbol a random multiplier between x5 and x9,999. A Disembodied Scatter on reel 2 or 4 can also trigger Mental Transform, turning into xWays, xSplit, a Dead Patient, a Wild or a Patient symbol.

xHole, xMental and the xGod Symbol

xHole is new, and it is one of the best mechanics in the game. It only activates when it lands in a Fire Frame or Fire Reel in the second position of reel 3. When it does, winning symbols are scattered to random positions and multiplied by x2, x4 or x8, before the xHole becomes a Wild.

xMental also needs a Fire Frame or Fire Reel to work. When it activates, you get one extra spin where every position is a Fire Frame, the Enhancers reveal only xWays, xNudge Wild or xSplit, and xHole is able to trigger. It is a single spin, but a very powerful one.

Then there is xGod. Land one xGod symbol on every reel in the same spin and the game pays the full 99,999x max win immediately. It is extremely rare, but it gives the base game a ceiling that most slots cannot match even in their bonus rounds.

The familiar xSplit, xNudge and xWays mechanics carry over as well, with xSplit able to create Super Scatters when it sits to the right of a Scatter.

Bloodletting, Surgery and ExperiMENTAL Spins

Three Cognitive Scatters trigger 8 Bloodletting Spins, where Fire Frames and Fire Reels stay sticky. Adding one Disembodied Scatter to the trigger gives 9 Surgery Spins, and adding two gives 10 ExperiMENTAL Spins. Each Scatter landing in a Fire Frame adds an extra spin, and each one in a Fire Reel adds two.

Surgery Spins make the Disembodied symbols sticky so they trigger Mental Transform every spin. A Dead Multiplier collects the highest Patient multiplier and its count, then applies it to that symbol's later appearances, with the count dropping each time.

ExperiMENTAL Spins are the top tier. Both Disembodied symbols are sticky, and the Dead Multiplier count never decreases, so it keeps growing as new Dead Patients are revealed. Both lower rounds can upgrade during play if the right scatters land.

Nolimit City puts the free spins frequency at about 1 in 249 spins, so patience is required.

Mental 2 RTP, Max Win and Boosters

The Mental 2 RTP is listed at 96.06%. Check the information screen of the version you load, because the paytable at your casino is the definitive figure.

The Mental 2 max win is 99,999x the base bet, and the round ends once that total is reached. Nolimit City puts the odds of hitting it at roughly 1 in 16 million.

Where available, the buy menu is built around Nolimit Boosters. xBet costs 1.4x the base bet and guarantees a Cognitive Scatter on reel 1. The Fire Frames booster costs 6x and fills every position with frames, the xHole booster costs 99x, and the xMental booster costs 3,200x. God Mode costs 6,666x and lets you chase the max win by trying to land xGod on every reel.

These options are removed in some regulated markets. The expensive ones carry enormous variance, so try them in Mental 2 free play before considering real money.

Our Verdict on Mental 2

Mental 2 is the rare sequel that improves on a classic without losing what made it special. xHole and Fire Reels add genuine new ideas, the free spins ladder is clearer and stronger, and xGod gives every single spin a theoretical shot at the top prize.

It earns our Masterpiece rating with a score of 10.0/10. For players who love high-risk, high-ceiling Nolimit City slots, this is about as good as the genre currently gets. If you enjoyed the original Mental, the sequel will feel familiar within minutes, yet it offers enough new tools to justify a fresh learning curve.

Remember that slots are random and no feature or booster guarantees a return. Please gamble responsibly and only play if you are 18 or over. You can try the free Mental 2 demo on ReelRadar whenever you like.
