Mental Online Slot Setup and Paytable

Mental is a 5-reel slot with a different setup than what we’re used to seeing. The symbols vary in height, and so does the setup. Nolimit City has done similar slots before – for example, Tombstone has a 2x3x3x3x2 setup as well. There are various mechanics in play in the slot, including Nolimit City’s xWays, xSplit, and xNudge mechanics.

Before we take a deep dive into the gameplay, let’s look at the visuals. Mental is a truly disturbing slot that’s on the verge of horror. It’s set in an asylum with scary patients unleashed on the reels. The Hannibal Lecter-lookalike pays the most, paying 5x your stake for five of a kind. There are other scary patients, too, along with a skeleton hand and a group of lungs. The sepia filter on top of the slot makes things even creepier, just like the soundtrack.

Nolimit City has done a truly immersive job with the visuals, so you won’t just be spinning the reels when you play – you’ll be heading to the asylum too.

Mental Slot Mobile Availability

The Mental slot was developed on HTML5 tech, so it’s available across a range of Android and iOS devices. Simply open it through your browser and play it with no download required.

Mental Online Slot Base Game

To start the journey through the creepy mental asylum, you will have to place a wager. Your options range between $0.20 and $70 per spin, varying enough for players from all walks of life. The controls are located right beneath the reels, so you shouldn’t have trouble playing the slot.

When playing a Nolimit City slot, you should be aware that the studio always mixes things up with several unique gameplay mechanics. The first one you’ll notice is the Fire Frames feature. On each spin, 1–13-reel positions can ignite in flames, splitting those symbols in 2. This is the xSplit mechanic, which is called Fire Frames in this slot.

On the bottom of reels 2 and 4, you’ll find special symbol positions known as Enhancer Cells. If you land 4 or 6 Fire Frames, these cells turn active. They can reveal different modifiers, including regular Wilds, xWays or xSplit symbols, an xNudge Wild, a Patient symbol, or a Dead Patient symbol.

When it comes to the latter, Dead Patient symbols come with a Multiplier attached. These can be as low as x5 and as high as x9,999 in the base game, offering serious wins. To trigger this feature, you will need 2 Dead Patient symbols anywhere in sight.

The last feature that you can trigger in the base game is called Mental transform. To trigger it, you’ll need the spider on reels 2 and 4. The Spider symbol can transform into a Wild, Patient, Dead Patient, xSplit, or xWays symbol, significantly boosting your wins.

Mental Slot Autopsy Free Spins

Land 3 Scorpion Scatters on the same spin, and you’ll get 8 free games to start with. Any extra Scorpion in a Fire Frame will add an extra spin to your tally.

Up to 5 Fire Frames are added to each reel during the Free Spins round, and they don’t reset between spins. The Autopsy free spins can be upgraded to Lobotomy or Mental free games, which offer even higher rewards.

• Lobotomy free spins: triggered by 3 Scorpions and a Spider on the same spin. You get 9 free spins with spider symbols triggering the Mental Transform feature. All other modifiers are active in this round as well. Dead Multipliers are also in the mix to spice up your wins.

• Mental free spins: triggered by 3 Scorpions and 2 Spiders. You get 10 free games with Fire Frame Scatters adding to your free spin tally. In this Bonus Round, Spiders are sticky and can trigger Mental Transform extras. Dead Multipliers rise by +1 as new mental patients are uncovered.
