Mental

Set in a torture chamber, this Nolimit City slot recreates the creepy atmosphere of horror films. Lobotomies, deceased patients, internal organs, and the haunting presence of a character reminiscent of Hannibal Lecter are just some of the first things you see when you start playing the game.

The Mental slot machine features an unsettling soundtrack that immerses the player in the chilling atmosphere, with discordant notes and eerie sound effects.

The combination of high-quality graphics, a haunting soundtrack, and a deeply disturbing theme ensures that the game stands out from typical slot games found at the majority of casino sites available today. It’s a game that demands attention, that’s for sure.

The Mental casino slot offers a flexible betting range. Players can start their betting with as little as $0.20 up to a maximum bet of $100 per spin. The payline setup provides players with 108 ways to win across the reels.

The game operates on a 5-reel and up to 20-row format featuring 14 symbols. The extensive number of win ways, detailed in the game’s paytable, significantly improves the chances of winning. 

Nolimit City has rated the game’s volatility as extreme. I like the fact that the Mental slot machine has high volatility. With everything that’s going on in the game, I didn’t mind because I did get some solid wins a few times.

The Mental slot RTP is 96.08%, which is around the industry average. Additionally, the game provides various feature buys, each with its own RTP percentage:

• Autopsy feature buy – 96.26%
• Lobotomy feature buy –  96.17%
• Mental feature buy – 96.68%
• Lucky draw feature buy – 96.42%

Last but not least, the Mental slot max win is 66,666x the bet amount. This extraordinary win potential is achievable in one out of 18 million rounds.

Winning combinations pay from the leftmost reel to the right across adjacent reels. The user interface includes options to toggle sound, select bet levels, enable fast spins, and start or stop the game rounds.

Patient symbols represent high-value symbols, while organ symbols are low-value, with payouts occurring for combinations of 3 to 5 symbols:

The Mental online slot autoplay feature allows players to set up the game to play automatically through a selected number of rounds, which is a nice touch.

Before deciding to play for real money, players should try the Mental free slot. Playing free casino games is always recommended because it is the only way to get a sense of the gameplay.

Mental is loaded with features and bonuses that make it fun to play, even if they may seem overwhelming at first. There are multiple free spins, symbol transformations, and more. Each feature gives you lots of chances to win big with multipliers and special bonuses, so let’s go over them.

Original Bonus Features

In the main game, positions 1–13 on the reels can randomly get a fire frame. Symbols landing within a fire frame will split into two parts.

The dead patient feature is triggered when two dead patient symbols appear on the reels. It unveils one of the patient symbols accompanied by a random multiplier. These multipliers can be as high as 9,999x, with the multiplier value reflecting the symbol count on that specific reel.

Enhancer cells are situated at the bottom of reels 2 and 4. They become active with 4 and 6 fire frames on reels 2 and 4. Enhancer cells can reveal any of the patient symbols or a regular dead patient symbol.

The Mental transform is activated by landing a spider symbol on reels 2 or 4. This symbol then transforms into one of the following: xWays, xSplit, dead patient, wild, or patient symbol.

Free Spins Features

Mental introduces a tiered free spins feature, with each level offering unique benefits and mechanisms:

• Autopsy free spins: Triggered by landing three scorpion symbols, autopsy free spins award eight bonus rounds. Additional spins can be earned through scorpion symbols with fire frames. Up to five positions may receive a fire frame in each spin, which stays put during the free spins round. 
• Lobotomy free spins: Achieved in the main game through a combination of three scorpion symbols and one spider symbol where you get nine spins. This feature includes all the benefits of autopsy free spins with the addition of the sticky spider symbol, which triggers the Mental transform feature during each spin.
• Mental free spins: Three scorpion symbols and two spider symbols in the main game activate 10 extra rounds. This level enhances the features of lobotomy free spins by making both spider symbols sticky and not removing the dead multiplier count after its transfer, allowing for an accumulation of multipliers.

Mental Bonus Buy

Players can directly purchase access to various levels of the free spin feature. The autopsy free spin bonus is available for 80 times the player’s bet for 8–11 spins. Nine to 13 lobotomy spins go for 230 times the bet, while mental free spins cost 1,000 times the bet. Lastly, you can access a combination of 50% autopsy, 40% lobotomy, and 10% mental spins for 232 times the bet.

xWays

The xWays feature is a game-changer, revealing three symbols of the same kind, thereby expanding the height of the reels. This unique mechanic significantly increases the number of ways to win. xWays can reveal any symbol except for the scorpion, spider, and dead patient symbols. Furthermore, if more than one xWays symbol appears on the reels, all xWays symbols will unveil the same symbol.

xSplit

The xSplit, when activated, splits one symbol on each reel and doubles those symbols, effectively forming winning combinations. Additionally, the xSplit symbol splits itself into two wild symbols.

xNudge Wild Mechanic

The xNudge wild aims for full visibility on the reel. Every time the xNudge wild nudges, the win multiplier increases by one level. When several wild multipliers are in play, they get combined, creating a total wild multiplier that can lead to incredibly lucrative payouts.
