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.
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.
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 –
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 –
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.
The 99,999x maximum win can be yours in any base game spin if xGOD appears on all reels. It’s worth a vast 9,999,900.00 at the highest stake of 100.00.
This is a very high volatility game, so expect plenty of non-winning spins, often countered by generous average prizes. Taken as a calculation over the long-term, the Mental 2 slot has a return to players of 96.06%.
