Mental Slot Overview

Mental is a new casino slot from Nolimit City, where we head to a terrifying mental institute. A place filled with highly insane people, where even the sanest person would go crazy after a long stay with constant exposure to the darkness and insanity that permeates this place. Nolimit City has certainly succeeded phenomenally in creating a scary atmosphere with the help of eerie music, sepia-toned design and blood-splattering knife cuts. Yes, the scary atmosphere is certainly a fact, but as a perfect balance to this darkness, there is also a brighter side in the form of skillfully created features and high potential MAX WINS.

Here you can enjoy a wonderful cocktail of xNudge, xSplit and xWays, which in their previous slots have proven to be very lucrative mechanics that can generate the most adrenaline-filled moments in front of the screen. We have previously seen these mechanics in, among others, San Quentin xWays and Bushido Ways xNudge. It is now time for us to open the gates to this madhouse and find out what you can expect to see during the spins.

Mental is a video slot from Nolimit City that has 5 reels and a row setup of 3-2-3-2-3. During the spins, the rows can increase to 20 and thus the from start 108 ways to win can increase significantly higher. You can choose between making a Min.bet of 0.20 and a Max.bet of 70. The game's RTP is 96.08% by default, but this can vary, so be sure to check what your gaming operator uses. It is a hit frequency of 34.19% and like the other slots from this game provider, it is an extremely high volatility. Something that certainly can create a sane mind is the high winnings that can be obtained, where it is possible to scoop up a win of 66666X the bet.

In order for the lucky player to be able to take part in the big wins, there are a bunch of great features that can be very helpful. The features are Fire Frames, Dead Patient, Enhancer Cells, Mental Transform, Autopsy Free Spins, Lobotomy Free Spins, Mental Free Spins and Bonus Buy.

Mental Slot Information

The game's design consists of an asylum theme, where in the background you can see a dilapidated room where the lights flash unpleasantly. It's a very evocative sepia filter used, where the scary sound effects that come with it really create a perfect touch to this scary theme. Mental is a slot that can be played on all the device’s mobiles, notepads and desktops. You create a winning combination by landing 3 or more of the same symbol type on adjacent reels starting at the far left.

Base game

The lower paying symbols consist of body symbols that show a hand, lungs, heart, brain and eye. All symbols are placed on a leather-like material, which makes the whole thing even more eerie when a knife starts cutting them during some features. If you land 5 of the same symbol type, it gives between 1X to 1.25X the bet. The higher paying symbols consist of patient symbols that show patient 5 to 1. If you land 5 of the same symbol type, it gives between 1.5X to 5X the bet. The yellow skull that has a W on the forehead is the game's wild symbol, which will substitute for other paying symbols to enable more winnings. You can also land spider and scorpion symbols which are the game's scatter symbols. The tombstone is the dead patient symbol that comes with wonderful qualities. Let's find out what the features do.

Mental Slot Features

What is the max win in the slot Mental?

You can win up to 66666X the bet.

What features are in the slot Mental?

The features are Fire Frames, Dead Patient, Enhancer Cells, Mental Transform, Autopsy Free Spins, Lobotomy Free Spins, Mental Free Spins and Bonus Buy.

Autopsy Free Spins feature

Fire Frames

When you spin the reels in the base game, 1 to 13 positions will randomly receive fire frames. Each symbol that lands within a fire frame will split into two symbols.

Dead Patient

This feature is activated when you land 2 dead patient symbols. Then one of the patient symbols will receive a multiplier of either 5X, 10X, 15X, 30X, 50X, 100X, 200X, 500X, 1000X or 9999X. The multiplier that the symbol receives reflects the number of symbols it contains.

Enhancer Cells

These enhancer cells are located at the bottom of reels 2 and 4, where you activate them through 4 and 6 fire frames respectively. These enhancer cells can reveal 6 different symbols that are and do the following:

Dead Patient = You land the dead patient symbol

Patient = You land 1 of the 5 patient symbols.

Wild = You land a wild that helps create more winning combinations by substituting for other paying symbols.

xWays = This will show 3 of the same symbol type, resulting in the rows increasing and thus the chances of winning greater. If you land multiple xWays symbols, they will all show the same type of symbol and the only symbols it cannot show are the spider, scorpion and dead patient symbol.

xSplit = This will split itself into 2 wilds and then all reels will get 1 symbol split into 2 symbols.

xNudge Wild = This will always nudge to be fully visible on the reel and with each nudge that occurs, the win multiplier will increase by 1X. If you have multiple wild multipliers, these will be added to a total wild multiplier.

Mental Transform

You activate the Mental Transform feature by landing a spider symbol on reel 2 or 4. What happens next is that this spider symbol will turn into a wild, dead patient, patient, xWays or xSplit symbol.

Autopsy Free Spins

If you land 3 scorpion symbols, the Autopsy Free Spins feature is activated, where these can only land on reels 1, 3 and 5. You will then receive 8 spins and each scorpion symbol that was within a fire frame will give 1 extra spin.

When you then use these spins, up to 5 positions per spin will receive fire frames. These will then stay during the remaining spins and within this feature you can also successfully activate either Mental Free Spins or Lobotomy Free Spins.

Lobotomy Free Spins

If you land 3 scorpion symbols and 1 spider symbol, the Lobotomy Free Spins feature is activated. You then receive 9 spins and each symbol that lands within a fire frame receives 1 extra spin.

If you spin the reels within the Autopsy Free Spins feature and land 1 spider symbol, the remaining spins will be Lobotomy spins and you will also receive 1 extra spin.

The spider symbol becomes sticky, which means that with each spin made, the Mental Transform feature will be activated. Within the Lobotomy Free Spins feature, you can also take part in the features that the Autopsy Free Spins have.

Dead Multiplier

The number and multiplier of each dead symbol will be collected with the highest value during the spins. Where, for example, 3 patient-4 symbols with 10X, 15X and 30X, give a count of 3 and a multiplier of 30X for the patient-4. Once this dead multiplier has been collected, its multiplier will be applied to the newcomers of the same symbol type, where the count size determines how many people that can take part in this. The count decrements by 1 each time a dead multiplier is given to a patient symbol.

Mental Free Spins feature

Mental Free Spins

By landing 3 scorpion symbols and 2 spider symbols, the Mental Free Spins feature is activated which gives 10 spins. If you spin the reels within the Autopsy free spins and land 2 spider symbols, the remaining spins are upgraded to Mental free spins and you also receive 2 extra spins. Finally, you can also succeed in activating the Mental Free Spins by landing 1 spider within the Lobotomy free spins, where you will also receive 1 extra spin.

Each scorpion or spider symbol that lands within 1 fire frame gives 1 extra spin. Within this feature, the two spider symbols will be sticky, resulting in 2 Mental Transform being activated with each new spin that occurs.

The big difference here is that the count on the dead multiplier doesn’t decrement when it has been applied to patient symbols. As a result, it can continue to increase during the spins. Within the Mental Free Spins feature, you can also take part in the features that the Lobotomy Free Spins have.

Bonus Buy

You can use the Bonus Buy feature if you want to take advantage of any of the bonus features directly. You then pay the following for the different:

80X = You can take part in 8 to 11 Autopsy Free Spins, where the RTP increases to 96.26%.

230X = You can take part in 9 to 13 Lobotomy Free Spins, where the RTP increases to 96.17%.

1000X = You get to take part in 10 to 15 Mental Free Spins, where the RTP increases to 96.68%.

232X = You will be randomly assigned one of the three bonus features. Where Autopsy Free Spins have a 50% chance of landing while Lobotomy Free Spins have a 40% and Mental Free Spins a 10%. With this Lucky Draw feature, the RTP increases to 96.42%.

Mental Slot Conclusion

Nolimit City is back again and this time with the slot Mental. Where we head to the terrifying mental institute that can give max wins of up to an incredible 66666X the bet. That this game provider is very skilled in design, features and mechanics is a fact and now they choose to place their slot in an asylum. Here you can take part in a wonderful mix of xNudge, xSplit and xWays which within their previous slots have proven to be very lucrative mechanics that can generate the most adrenaline-filled moments in front of the screen. During their very productive 2021, they released many bangers including, Bushido Ways xNudge, San Quentin xWays, Fire in the Hole xBomb and East Coast vs West Coast, among others. It is truly a wonderful mix of environments that we have jumped between, where high volatile spins are mixed with exciting features generating big thrills during the spins.

We now have the chance to visit this eerie place and find out what features we have for help in the hunt for the insanely high max wins that are offered. Like when Leonardo DiCaprio visits the madhouse on Shutter Island, this place is also surrounded by enormous mystery, excitement and a great deal of insanity. There is a lot to keep an eye on at first, which can make one a little crazy, but everything becomes clearer the more you play.

In addition to its wonderful effect, the fire frame also gives a good touch to the spins, where it divides the symbols that land within its frame. The multiplier of up to 9999X that the dead patient can receive can give an explosive start to big wins. The Enhancer cells is a feature that has become something of a hallmark for slots from this game provider, where this time we get to take part in a fantastic set of symbols where patient, wild and dead patient can land. You can also see the wonderful features that xWays, xNudge and xSplit have with the help of the enhancer, where Nolimit City certainly hasn’t skimped on the effects. When the xSplit is activated, knives appear that cut up more symbols, which is a rather grotesque sight at first, but in this context, it is really a mood setter.

There are three different Free Spins feature which are Autopsy, Lobotomy and Mental, where better conditions are given at the latter and that is why it is without a doubt the most expensive option within the Bonus Buy feature. There it costs 1000X the bet to activate the Mental Free Spins feature. There the count doesn’t drop on dead multipliers, and 2 spider symbols activate the Mental Transform with each new spin made. There is no question that Nolimit City is in a good momentum when it comes to launching games. Where they this time give us a gaming experience with high potential maximum winnings, impressive design and captivating features that make you sit glued to the screen for a long time. That being said, there is also a crazy high volatility on this slot, and it can sometimes take a very long time before winnings are generated.

Mental is a slot where we visit a mental hospital, where its dark, scary and atmospheric theme can generate a game with insanely high max wins.
