Mental is one of those slots that remain in history, and this time it’s because of the unique story and the impact it made on the entire slot industry. Dark and brutally honest, it doesn’t shy away from showing gruesome images of barbaric medical practices used by mental hospitals. So, this one is definitely not for the faint-hearted.  

Mental Nolimit City

Before the release of Mental, the slot industry was a place of fairy tales, fruits, cute characters and all sorts of gods. But the success of this Nolimit City’s masterpiece convinced the industry that there’s a high demand for darker themes. So, other studios started to follow Nolimit’s footsteps sprinkling a bit of raw horror spice on their otherwise sweet and shiny portfolios.  

The slot went on to be an incredibly popular one, landing 13th in our Best New Slots of 2021 and 26th in our Top Slots of 2022 ratings. Of course, the intrigue of this unconventional slot theme must have played a big role, but it wasn’t without the help of an amazing gameplay. Mental is packed with an insane number of features and bonus rounds. Throw the 66,666x max win into the mix, and you get multiple reasons to love this slot. 


Mental slot features

For quite some time Nolimit City was known for its Extreme Volatility level. But then it boosted the values even higher introducing Insane Volatility, and Mental is one of the first of their insanely volatile games. The slot doesn’t introduce any new features, but it’s one of the first to have so many of them at the same time. Here are boosters and features it offers: 

  • xWays, xSplit, and xNudge. Before the release of this game, there weren’t any slots that featured not one or two but three xMechanics at the same time.  
  • Enhancer Cells are also something that fans had already seen in the studio’s previous releases. This time they are activated by the Fire Frames and reveal high value symbols, wilds or feature symbols.  
  • Up to x9,999 multiplier when 2+ Dead Patient symbols land in view. This massive multiplier adds another level of insanity to this slot, but to get the high values, you’ll need a lot of those symbols.  
  • Transformation. Spiders landing on reel 2 and 4 transform into high value or special symbols. 

You can have fun by jumping right into testing all those crazy features the studio mixed together. Play free Mental slot right on this page. And it’s very convenient to have multiple bonus buy options, because you can enter all of them instantly and trigger all available boosters.

Bonus Games  

There are three bonus games you can enter. All three have different names, but you can basically say that they are just three levels of the same free spins round. You’ll get more spins and an extended set of boosters the more bonus symbols landed.  

  • 3 Scorpions award 8 free spins with Fire Frames that do not reset between spins.  
  • 3 Scorpions + 1 Spider unlock 9 free spins. Just like Fire Frames, Spiders become sticky and every round they trigger the Mental Transform feature. Plus, Dead Multipliers for each Patient are collected and then applied to their respective Patient symbols.  
  • 3 Scorpions + 2 Spiders trigger the most promising version of the bonus. 10 free spins with all the features from the earlier levels, plus both Spiders sticky and triggering Mental Transform in every round. Dead Multipliers count doesn’t go down as in the previous bonus round and can only go up.  


Mental lives up to its name. It tells a disturbing story set against the gruesome backdrop of a mental hospital where patients are ‘taken care of’ and features an insane pack of features. This release made a big impact on the landscape of the slot industry, and that makes it even more significant.
