Mental 2 Online Slot Review
Nolimit City take you back to a grimy, disturbing asylum in their Mental 2 online slot. Sepia-toned patients and body parts appear in a 3-2-3-2-3 pattern, with 108 ways to win running from left to right.
Like other games from this studio, the Mental 2 slot machine has a wide range of extra features. These include splitting symbols which increase the number of winning ways, wild symbols with multipliers, and 3 levels of free spins. Depending on how many bonus symbols trigger the round, the enhanced features in free games include more modifiers, sticky symbols, and ever-increasing multipliers.
The volatility is extreme, and the return to players is 96.06%. You can enter the asylum across desktop and mobile devices at our recommended slots online uk casinos, where the maximum win from the Mental 2 slot is an insane 99,999x the stake.

How to Play the Mental 2 Slot Online
Be warned, this is not a game for the squeamish, and there’s even a warning notice as the game loads. An introductory sequence shows a young girl entering a hellish institution, where the walls are covered in blood, grime, and graffiti. Once incarcerated, you’ll find skulls, spines, and ribcage symbols alongside higher value patients in various states of distress, with a yellowish tint to the characters and parchment style reel backings. Screams, clanging cell doors, and a haunting tune add to the unsettling sights.
You can join in the fun with stakes from 0.20 to 100.00, and there are many options in between these limits. Multiple bonus buy features are available in some countries, but not the UK, where local players are also blocked from the Auto and Turbo options.
A read through the paytable, accessed via the 3 lines button, is highly recommended, as Mental 2 is a complex game. You’ll find details on the many features, along with a table of symbol values which changes to reflect the bet size. You win 0.1x, 0.25x, and 0.5x the stake for the lowest value foot bones on 3, 4, or all 5 reels, with a patient behind bars paying the most, at 0.5x, 1x, and 2.5x.
It’s compatible with desktop devices, Android, iOS, and Windows mobiles on your favourite uk betting apps, and apart from some controls repositioned for ease of use, there’s no difference to the game on any platform.
Free Spins & Other Features of the Mental 2 Slot Machine
Symbol positions burst into flames at random times. These Fire Frames split symbols within into 2 one above the other, increasing the number of ways to win from the basic 108. Entire reels can become Fire Reels and if they engulf the entire grid, symbols split into 3.
They also activate modifiers from Enhancer Cells underneath reels 2, 3, and 4. Any 4, 6, or 8 Fire Frames and Fire Reels trigger any of the following features from 1, 2, or all 3 Cells respectively –
- Wild symbol. This substitutes for others if it can complete winning combinations.
- xSplit. Splits symbols above, then transforms into a wild symbol.
- xNudge Wild. Nudge until they fill all rows on their reels. A multiplier increases by 1x on each step taken and applies to any subsequent win.
- xWays. Chooses up to 3 symbols at random and expands the height of any reel they are on. If more than 1 symbol is picked, they all transform into a single type.
An xHole symbol on the middle reel sucks in all symbols apart from xNudge wilds, and replaces them with 2x, 4x, or 8x multiplier versions.
The xMental symbol in a Fire Frame or on a Fire Reel sets the rest of the game alight, which activates all Enhancer Cells at once.
A Disembodied scatter symbol on reels 2 and 4 triggers the xMental feature, as they transform into xSplit, xWays, Wilds, Patients, or Dead Patients.
Dead Patients reveal a multiplier from 5x to 9,999x, which represents the number of symbols they become. It’s not a prize multiplier though.
If an xGOD symbols tops on all 5 reels of the Mental 2 online slot, it pays the maximum possible 99,999x your bet right away.
Different combinations of scatter symbols unlock the various no deposit free spins features as follows –
- Bloodletting Spins. Cognitive scatters on reels 1, 3, and 5 award 8 free spins. Once triggered, any Fire Frames and Fire Reels remain active for the rest of the feature.
- Surgery Spins. Triggered by 3 Cognitive and 1 Disembodied symbol. You get 8 spins, and the Disembodied symbol remains sticky, awarding xMental transformations throughout. This is on top of Sticky Fire Frames and Fire Reels
- Experimental Spins. Land 3 Cognitive and 2 Disembodied scatters to get 8 spins which play out in the same way as Surgery games. The difference is that any Dead Patient multipliers remain active.
Whichever free spins you get, scatters in Fire Frames add 1 extra spins, and you get 2 more if scatters appear on Fire Reels. Bloodletting and Surgery spins can upgrade with more Disembodied scatters.

Our Mental 2 Slot Rating
The theme won’t suit everyone, it comes with very high volatility, and the complexity could make it unsuitable for novice players, but we expect this from Nolimit City. If you enjoy edgy, feature-filled slots with the potential to pay huge prizes, then it’s a highly recommended game.
Enter the asylum to find splitting symbols, nudging wilds, a rich variety of modifiers, and several layers of free spins within this blood-spattered institution. It’s enough to make your head explode, but the rewards can be huge as you play the Mental 2 slot at our favourite casino uk sites online.
