mental demo slot

Nolimit City is a relatively new slot developer based out of Malta but has already expanded with international offices in both Sweden and India. Mental Slot is one of the spookiest games we’ve seen in a while and clearly takes some inspiration from the ever-popular Megaways slot machines. With a flexible number of pay ways starting at 108 and a maximum win of 66,666x your stake, are you ready to dive into the world of the Mental?

Mental uses an unusual reel layout that starts in a 3x2x3x2x3 configuration, though this changes from one spin to the next depending on the size of the symbols, split symbols, and transforming symbols. It’s a relatively complex setup, so rather than try and compress it down into a brief synopsis, we’ll let the rest of our review explain the finer points of this new and exciting slot machine.

So let's join the residents of the asylum in this creepy looking game, and don't forget you can try it our for fun in the free demo slot of Mental that's a part of our full article. This can be accessed and played on your desktop, tablet, and mobile devices.

mental slot theme, stakes, pays & Symbols

Paytable for Mental Slot

The theme of Mental is best described as being horror-inspired – think the Asylum series of American Horror Story, or the 2011 movies “Grave Encounters” or “Paranormal Incident”, and you’ll get the idea. As for other slots of the same nature, there are dozens of horror-themed slot machines, but none that I know of with the same asylum kind of feel as Mental. Nolimit City has absolutely nailed it with the visuals, from the creepy symbols, the spooky backdrop with flickering lighting, and the random fire that divides the symbols to create additional pay ways – it’s a masterpiece of visual design. Sound-wise, the studio has chosen to keep the reel sound effects fairly muted, emphasizing the ambient backdrop which might have benefitted from the odd jump scare, although we guess that would get old quickly.

Checking the paytable out for the first time, we were surprised to see the first entry labelled “Dead Patient”, which promises multipliers of between x5 all the way up to x500, x1000, and even x9999! Apparently, the exact multiplier you will receive depends on the number of symbols on the reel, which we eventually realised refers to the number of times the reel with one of the dead patients showing has split into two. We couldn’t establish just what the maximum number of pay ways this game can max out at, but we saw over 100,000 during our testing and the paytable states that each reel row can split a maximum of 20 times. As always with many-ways games, the payouts for the symbols themselves are nothing special – the picture symbols pay just 5x, 3.75x, 2.5x, 2x, and 1.5x your stake for five-of-a-kind.

In sharp contrast, the bet spread on this game is enormous – a minimum of €0.20 is required to spin the reels, whereas the truly brave can bet as high as €70.00 per spin! If you should find yourself doing this, we advise you to take another long, hard, look at the game's title before continuing.


base game & modifiers

Play with 5 reels, up to 1 billion paylines, and win up to 66,666x your stake on Nolimit City's Mental online slot

We’re going to do our best to explain all the various bonuses and modifiers in Mental as best we can, but this is one complex slot with all kinds of twists and turns, and even the paytable doesn’t do the best job of accurately explaining all of them. For that reason, we apologize if we miss anything out here.


fire flames feature

The paytable states that one to thirteen positions on the reels will randomly become enveloped in a fiery flame, and all symbols that are trapped inside a frame will split into two parts. As there are a total of thirteen spots in a 3x2x3x2x3 layout, this means every symbol can split multiple times!


dead patient feature

We mentioned this feature earlier as having taken us aback at first glance, but here’s the full detail from the paytable: The dead patient feature is activated whenever there are 2 Dead Patient symbols. One of the dead patients will then be selected and reveal a random multiplier of either 5x, 10x, 15x, 30x, 50x, 100x, 200x, 500x, 1000x, or 9999x. The multiplier chosen reflects the number of symbols on the reel where the selected patient is shown and multiplies your entire win for that spin. Wow!


enhancer cells

These special cells are located at the bottom of reels two and four. The reel two enhancer cell will activate when four fire frames appear on the screen, whereas the reel four enhancer cell will only activate if six fire frames are displayed on the screen. The enhancer cells can reveal one of six possible outcomes:

  • A regular picture symbol.
  • A dead patient symbol.
  • An xWays symbol, which reveals 3 symbols of the same kind and expands to the height of the reel. The xWays symbol cannot reveal special symbols such as the bonus scatter or Dead Patient symbols, but if two xWays symbols are revealed on the same spin, all of the revealed symbols on both reels will be of the same type.
  • An xSplit symbol, which splits one symbol on each reel and then splits the resulting extra space into 2 wilds.
  • The regular wild symbol.
  • An xNudge symbol, which will perform a random number of nudges increasing a winning multiplier by one for each nudge. Several revealed wild multipliers can add together with each other for an even bigger Wild multiplier.

mental transform feature

Landing a spider symbol on both reels two and four triggers the mental transform feature. Each of the two spiders will be transformed into one of the following symbols: Dead Patient, Wild, Regular Picture Symbol OR (See Above) the xWays or xSplit symbols.


mental slot free spin features

Trigger 3 free spin features on Mental video slot from Nolimit City

As if that wasn’t enough modifiers for one slot, Nolimit City has also seen fit to include multiple free spin modes in this title as well. Are you ready? Here we go again…


autopsy free spins

The scorpion symbol appears only on reels 1, 3, and 5 during the base game, and if you hit three of them you will be awarded eight free spins, but if any of the scorpions are contained within a fire frame, an extra symbol will be awarded up to a maximum of eleven.

One to five fire frames are guaranteed during every spin during the autopsy free spins, and once they appear they will remain in place for the duration of the feature. The autopsy free spins can also be upgraded to lobotomy free spins by catching a spider on reels two or four. If this occurs, the free spin counter will not reset, but all remaining free spins will be played as lobotomy free spins instead of autopsy free spins.


lobotomy free spins

Catch a spider as well as three scorpions to win yourself the improved lobotomy free spins right from the start. Like the Autopsy free spins, any triggering symbols surrounded by fire frames increases the number of starting free spins. If you land a spider during the lobotomy free spins, it will remain sticky for the remainder of the feature and trigger a mental transform on each remaining spin.

A complex system of multipliers and counts is initiated in the lobotomy free spins which can multiply the value of each of the picture symbols on the paytable. During testing, we saw multipliers of up to 15x achieved, which represented a major improvement on the 5x win normally received from the top picture symbol.


mental free spins

Predictably, catch both spiders along with all three scorpions to trigger Mental’s ultimate free spins mode, which throws every feature imaginable plus the kitchen sink into a slot sized dish, whisks them for 30 minutes on high-speed, and then explodes in your face in a disturbing episode of what can only be called “mental slotting”. Unlike the lobotomy free spins, the aforementioned complicated system of counters and multipliers does not decrease after each spin as it does in the lobotomy free spins, ensuring that with the right amount of luck, you can end up with a screen full of sticky symbols that are paying out thousands of times your stake on every free spin.


bonus buy option

Those players who have decided to take on Mental from a jurisdiction where it is still possible to buy a feature on a slot, can gain instant access to all 3 free spin features. So to buy your way into the Autopsy Free Spins, Lobotomy Free Spins, and Mental Free Spins, it will cost you 80x, 230x, and 1,000x your stake respectively.


mental slot review final thoughts

What can we say? It took hours of play to write this review, and personally, I still don’t really think I understand everything this game has to offer. I’m not much of a horror fan, but something about the creepy asylum theme has always appealed to me much more than typical slasher flicks, so this game is actually right up my street. I’ll definitely be checking this one out in real money mode soon.
