Mental online slot game

Brutal and intense gameplay is a specialty of Nolimit City, and their Mental slot is no different. Packed to the brim with creepy visuals and an eerie soundtrack, this slot transported us to the middle of a mental asylum, making us fear both for our money and our lives. That might sound like an unpleasant experience, but Mental is anything but that, especially for fans of the macabre like us. Not to mention that the studio leaves no stone unturned in designing a complicated yet thrilling set of unique slot features. So, hold on to your seatbelts as we explain everything you need to know about this dynamic slot!

Everything About the Graphics and Sound of Mental Slot

Mental 1

Mental is set in an asylum, which is why it made perfect sense when we were welcomed by sepia tones and startling shots. The background features a worn-out room with flickering lights, which work together to create an air of unease. The whole scenario kept us on the edge of our seats the entire time.

The petrifying music is paired with equally scary sound effects, both of which add an extra layer of terror to the game’s setup. We couldn't help but notice how the setup reminded us of the Silence of the Lambs, which is why we do not recommend this slot for the faint of heart.

We even found direct comparisons with the film in the game’s visuals, such as a Hannibal Lecter-style mask on one of the symbols. It’s safe to say that anyone who likes immersing themselves in uncanny and spine-chilling worlds will enjoy this game to the fullest, just like we did.

How to Play Mental

Mental has 5 reels, 3 rows, and 108 paylines, but we wouldn’t recommend getting underwhelmed by that number. Even within this limited grid, Mental manages to pack in a high level of stimulation which proves that Nolimit City actually surpasses all limits in its gameplay.

We were faced with the game's many symbols at every turn. The slot’s lower-paying symbols are represented by body parts such as a skeleton hand, lungs, an eye, a brain, and a heart. These pay varying levels from 0.1x to 1.25x the bettor’s stake.

The next tier is patient symbols, which pay anywhere from 0.4x to 5x the stake. We found the Hannibal Lecter-like patient, officially known as Patient 1, to be the highest-paying among this group. During our gameplay, we managed to locate five different patient symbols.

There is a skull wild symbol, and two scatter symbols represented by a scorpion and a spider. The last is a Dead Patient symbol, landing two of which opens up a special multiplier feature. The multiplier amounts vary and range from 5x to 9,999x.

The basic gameplay is quite simple - all we had to do was land at least three matching symbols to trigger a winning combination. However, despite the obvious ease of the slot, we noticed that its exciting features added multiple layers of complexity and intrigue to the game, uplifting it from being just another slot.

Mental 2

If you would like to get first-hand experience with every feature we encountered in the Mental slot game, we recommend trying the demo version on our website. This game can be a little too much to take in if it’s your first time playing, so trying out a demo will help you get a lay of the land.

The best part is that our website lets you try out the game for free, without worrying about betting any real money on it. So press that play button today and witness the stuff of nightmares come to life around you!

Bonus Features in Mental Slot

Mental 3

Because of our prior experience with similar horror-themed slots by Nolimit City, we were already aware that the provider does not play around when it comes to its bonus features. Each spin left us pleasantly surprised as we waited for another exciting feature to unravel itself. Here are some of our favorite bonus features that we found in this slot:

  • Fire Frames: Bettors will randomly find a few reel positions engulfed in flames during a spin, known as a fire frame. As soon as a symbol lands within the flames, it will split into two. These fire frames can be collected to land big winning combinations.
  • Dead Patient Symbols: As mentioned before, the Dead Patient feature results in a multiplier, which could have a range of values. The feature gets triggered when players land two Dead Patient symbols. We weren't fortunate enough for the big wins, but if your luck strikes, you could end up with a multiplier of 9,999x on a regular Dead Patient symbol.
  • Autopsy Free Spins: Once we landed three scorpion symbols, the game triggered the Autopsy Free Spins. This feature offers eight free spins, while also adding extra fire frames during each spin.
  • Lobotomy Free Spins: If a bettor lands a spider symbol in addition to three scorpions, it triggers the Lobotomy Free Spins. We were rewarded with nine free spins, along with some fire frames and other multipliers during this feature.
  • Mental Free Spins: This is the last free spins tier for the Mental slot. The Mental Free Spins can be triggered by landing two spider symbols in addition to three scorpions. Once this feature was activated, we were awarded ten free spins, along with all the features of the previous two tiers and some extra ones as well.
  • Mental Transform: If a spider symbol lands on the 2nd or the 4th reel, it will trigger the Mental Transform feature. While this feature is active, the spider will be transformed into another feature, such as a wild, Dead Patient symbol, or a patient symbol. We noticed that this feature can also be triggered during the free spins.
  • Enhancer Cells: There are special symbol positions at the bottom of the 2nd and 4th reel, known as Enhancer Cells. These will be activated if a bettor receives four or six fire frames, respectively. Each enhancer cell then transforms into a special symbol such as a patient, a wild, or others.
  • !!!This is Mental!!!: If the urgency doesn’t become obvious to you through the name, this is the max payout feature, which is set at 66,666x for this particular game. Yes, we understand the irony of that number, as does any horror fan. Triggering this will end the round right away, giving you ample time to revel in your winnings.

Winning Strategies for the Mental Online Slot Game

Mental 4

Now that we’ve given you a look into all the excitement that awaits you in the Mental slot game, you know you can’t take it lightly. Slots might seem random to you, but here are a few winning strategies we were able to jot down while taking a shot at this slot:

  1. Don’t step into it without playing the demo version: Unless you want to be ambushed by a billion different features coming at you at once, take a walk through the demo version. It will help you familiarise yourself with the game’s mechanics.
  2. Keep an eye on the symbols: The Mental slot has a wide range of symbols to begin with, but a lot of them keep transforming during the gameplay as well. The game can be quite sneaky in this regard, so make sure that you have your eyes glued to the reels at all times.

All the Technical Details

Mental has an RTP of 96.08%, but the real (pun intended) magic lies in the hit frequency, which is set at 34.19% for this game. The game is highly volatile, and the maximum payout is 66,666 times your bet. The minimum bet is €0.20, and the maximum bet is €70. We hoped to hit the maximum payout on our max bet, because that would have paid out more than 4.5 million Euros. We weren't that lucky, but maybe you will be!

Best Alternatives to Mental Online Slot

The Mental slot is one of the best asylum-themed slots in the market, but it’s not the only one to give us the creeps. Here are a few other horror slot games that we definitely recommend for all the adrenaline-seekers out there:

  • Immortal Romance: This Microgaming slot is the perfect balance between the genres of romance and the supernatural. Offering an RTP of 96.96% and 243 paylines, this is one of the most popular slots by this provider, and for a good reason.
  • Blood Suckers II: This sequel to the original Blood Suckers is as exciting as the classic version, if not more. NetEnt has really done a fantastic job with this game’s graphics and storyline. The RTP stands at 96.94%, and the game has 25 paylines.

Final Verdict

There is so much going on in the Mental slot game at all times, that too in the dark side, that it’s a must-try for people who call themselves horror fans. If you’re looking for a fun, lighthearted slot, then this is not for you. But if you’re someone who likes veering off into the world of asylums, unsettling visuals, and blood-curdling sounds, you’re at the right place. This is one of the best slots by Nolimit City, one which proved to us just how masterful this gaming provider is in its field.
