Pros

  • Great follow-up to what was already an outstanding slot
  • Insane max win of nearly 100,000x
  • Eerie, scary and captivating

Cons

  • Beware of lower RTP versions out there!
  • Not for the faint of heart, both in terms of subject matter and in variance

Mental is one of those online slots that really emphasises what game studio Nolimit City is about. Creating unique games for the online casino industry with special features and different (and provoking) themes with high max win potential.

NLC just has the guts to create the kind of online slots that other slot developers wouldn’t dream of doing. This strategy puts them in a certain light and makes them stand out from the rest. The best part is that they do their craft exceptionally well, too.

Mental and similar NLC slots might not be for everyone, but the ones who enjoy them love playing these games. And here comes the sequel, Mental 2, where we again enter the scary mental institution.  

Nolimit City tends to pack its games with an overload of different features, and the same applies to Mental 2.

Some of these include features such as:

  • Improved Fire Frames
  • Multipliers
  • xSplit, xNudge, and xWays symbols
  • 3 bonus games

Mental 2 RTP

Mental 2, like all other Nolimit City games, is released in different payout versions, and the Return To Player (RTP) might differ depending on where you play.

This basically means that, on average, your money will run out faster if you play on a low RTP version, while a higher RTP will increase your chances of winning as you can get more spins.

You wouldn’t pay more for an item if the shop next door could offer you a lower price, right? Well, the same applies to online slots.

Mental 2 is available as an 84.01%, 92.02%, 94.04%, 95.23%, or 96.06% RTP version.

So, what’s the difference between the options?

To illustrate the effect of a higher RTP compared to a lower RTP, we have made some calculations. The following table shows how many spins you will theoretically get to play before your money runs out, based on a starting balance of £100 and a stake of £1 per spin.

How to play

Mental 2 is even more volatile than your average highly risky slot, as it is rated 12/10 on the volatility scale.

It is played on a 5-reel, 3-2-3-2-3-row game panel with 108 ways to win. The possibility of splitting symbols can increase this even further.

The highest-value pay symbols are the five mental patients (or victims). You win by matching three or more pay symbols from the leftmost reels, and the wilds play a vital role in this game.  

When playing from the UK, you can start playing at 20p per spin, rising to a maximum of £2 per spin when aged 18-24 and £5 per spin when aged 25 or older.

Mental 2 slot features

Mental 2 can offer plenty of action through the different features. Some are familiar, while others are new.

Fire Reels

Before any spin, you might see 1-5 reels on fire. The symbols in these highlighted areas are split up into three parts, tripling their values.

Dead Patient

You need at least two tombstone symbols in view to trigger this feature. When active, these will transform into a high-value symbol with a multiplier of x5 to x9,999.

Enhancer Cells

Underneath reels 2, 3, and 4, you find locked areas. These will show special symbols when you land 4, 6, or 8 Fire Frames.

The special symbols will consist of Wilds, xSplits, xNudge Wilds, Patient Symbols, or xWays.

xHole

The xHole symbols can appear in the middle reel when that space is on fire. When triggered, it collects all symbols in view and places them in new positions while splitting them into 2, 4, or 8 parts.

xMental

This is a valuable symbol that is triggered when it lands on an area that’s on fire. When activated, you get an extra spin where you get more Fire Frames, xSplits, xWays, or xNudge Wilds, and your chances of triggering the xHole feature increase.  

xGod

When landing the xGod symbol on all 5 reels, you win the game’s maximum win of 99,999x the stake.

Mental Transform

There are two sets of scatters in this slot. When you land the head scatter on reels 2 and 4, you trigger the mental Transform feature. These scatters will then transform into a high-value symbol, xSplit, xWays, Wild, or a Dead Patient symbol.

Bonus Games:

Blodletting Spins

Three brain scatters trigger 8 Blodletting Spins where any Fire Frames remain sticky for all remaining spins.

Surgery Spins

Three brain and one head scatter trigger 9 Surgery Spins.

Any head scatters are sticky in this bonus game and trigger the xHole feature during all remaining spins. Here, you also collect multipliers from the Dead Patient symbols, which are given to the most valuable symbol on the next spin.

Experimental Spins

Three brains and two head scatters trigger 10 Experimental Spins.

In this version, any scatter remains sticky and triggers the xHole feature. These spins are also potentially extra valuable as the multipliers collected from the Dead Spins symbols don’t reset after a spin.

Mental 2 Bonus Buy Options

UK players can’t buy free spins or other bonuses, but these options are available for international players.

However, seeing how much they cost can give you an indication of their “values.”

  • xBet: Costs 1.4x the bet and guarantees a brain scatter on the first reel.
  • Fire Frames: 6x the bet for guaranteed Fire Frames
  • xHole: 99x the bet
  • xMental: 3,200x the bet
  • Blodletting Spins: 100x the bet
  • Surgery Spins: 250x the bet
  • Experimental Spins: 1,800x the bet  
  • Lucky Draw: 330x the bet (50% Blodletting Spins, 40% Surgery Spins, and 10% Experimental Spins)
  • God Mode: 6,666x the bet. One spin where you win the max win or nothing.

What’s special about Mental 2?

An online slot that takes place in a mental institution is different, for starters.

The added spookiness that resembles something seen in horror movies is also something that stands out.

The different features in play bring it all together in a very good way. It might take you a bit of time to understand everything, but once you do, it will all make sense.

What is the maximum win on Mental 2?

Mental 2 is one of Nolimit City’s biggest max win slots, as you can win up to 99,999x the bet.

However, remember that this is also an ultra-risky online slot, so play it carefully.

Your biggest chance to reach the big wins is through the free spins, which will trigger, on average, 1 in 269 spins.

Mental 2 is everyone’s worst nightmare, and that is exactly the point of this game (8.5 out of 10)

These mental hospitals created by Nolimit City aren’t very friendly places, to say the least. In Mental 2, they have also managed to elevate that unpleasant feeling to an even higher degree.

They have created other slots in his genre like Serial, Disturbed, and Kiss My Chainsaw, and it must be said that the vibe in Mental 2 is among the scarier ones.

One thing is for certain: Nolimit City has found its niche, and it has mastered it better than anyone else.

This slot also offers plenty of features. The only downside could be that it might cost you to experience them, as this is an extremely highly volatile slot where you can win huge amounts but also lose your funds quickly. The risk factor goes well with this overall theme, though, and suits it well.

The features are cleverly made, with the improved Fire Frames and bonus games standing out. The different free spins modes in this version create plenty of variety if you get that far.

If you enjoyed the first Mental slot, then it is a no-brainer to play this one, too, as it’s at least equally good, if not even better. NLC has also managed to nail the soundtrack on this version, which is spot on.

However, if you prefer a more friendly theme, this is definitely not for you, as some disturbing images are seen in this slot.

CasinoWizard’s final verdict: 8.5 out of 10 stars.

Mental 2 is available at UK casinos starting March 25, 2025.
