Mental Slot Game – Demo, RTP & Features

Mental is one of Nolimit City’s darkest and most unsettling slot machine games, and we think it’s fair to say that it definitely pushes the boundaries of what counts as entertainment!

Set in a Victorian-era asylum, the game’s atmosphere is chilling, and you’ll see flickering lights, handcuffs chained to pipes, and a creepy sound effect that really feels like a psychological horror movie.

The game’s played on a five-reel layout, and it uses a unique 3-2-3-2-3 format. There are a total of 108 paylines, although more can appear dynamically throughout the gameplay.

Mental Slot Game is easy to play, and you can wager bewteen $0.20 and $70 per spin – so players on pretty much every budget will find a stake size suitable for them. The game is also fully mobile optimized, so you can enjoy the slot’s action from both your desktop computer and mobile device!

Now, as is the case with most recent Nolimit City releases, Mental is volatile. In fact, the software provider classes it as being extremely volatile – so expect very lengthy stretches without much in the way of wins! This, however, is made up for by the fact that there’s a whopping 66,666x up for grabs in win potential!

Game Features

At the core of Mental’s base game is the Fire Frames mechanic, which can appear on 1 to 13 positions per spin. Symbols landing in these flaming frames split into two, increasing not just the active ways-to-win, but also the win potential!

Adding to the intensity is the Dead Patient feature. Triggered by landing two Dead Patient symbols, this bonus reveals one of the premium patient symbols with a random multiplier ranging from x5 to a staggering x9,999. This multiplier represents the number of symbols counted in a win, rather than a direct win multiplier.

Enhancer Cells sit at the bottom of reels 2 and 4 and activate when 4 or more Fire Frames land on these reels. These cells reveal modifiers like extra wilds, patient symbols, or unique xWays and xSplit mechanics…

And while that all sounds great, Mental’s real win potential is found in its free spins bonus round. Landing three Scorpion scatter symbols awards 8 Autopsy Free Spins, during which Fire Frames become sticky.

Upgrading to Lobotomy Free Spins (achieved by landing a Spider symbol with the Scorpions) adds sticky Spider symbols and introduces Dead Multipliers, which are carried over and applied to new patient symbols.

The ultimate goal, however, is to trigger the Mental Free Spins, which requires three Scorpions and two Spider Symbols. This feature awards 10 spins, where both Spiders remain sticky, transforming symbols on every spin and maximizing the chances of hitting monstrous wins!
