Mental is one of the online slots every slot fan was waiting for in 2021. Developed by legendary provider Nolimit City, this is no doubt the creepiest online slot you have ever played with. Be prepared for a setting in a deranged mental hospital, with all sorts of patients (deal and alive) and the worst psychotherapies you can ever think of.. the look and feel of this slot is just so perfectly creepy, no wonder why the producers of this game have a reputation for being among the very best out there.

On top of offering the perfect look and feel (you might want to check other slots by the same provider, like xWays Hoarded xSplit or Infectious 5 xWays) this game also offers a high RTP of 96.08%, a very highly volatile model and Bonus Buy Feature. But the most important thing here is of course the special features of the slot, like xWays, xSplit and xNudge, or the 3 reel modifiers, or again the complex Free Spins bonus round. Let’s start looking at this and see what this is all about!

Bet Range and Paytable

In Mental bets range from 0.20 to 70, offering a wild range of possibilities to all players (both those on a budget and high rollers). Of course, the maximum win you can achieve with this game is x66.666!

Looking at the paytable, we see lower-paying symbols being 5 organs, namely the heart, lungs, eyes, brain and the bones of a hand. Premiums, on the other side of the spectrum, are 5 patients. The poor souls don’t have a name, just a number. Patient 1 looks somewhat like dr. Lecter, and is the highest paying symbol in the paytable. It will pay 5x the stake for a combination of 5.

Reel Modifiers: Fire Frame, Dead Patient & Enhancer Cells

fire frame

This game has a lot of action to offer, both during basegame and the special feature. Looking at the basegame, there are 3 special reel modifiers you will see unfolding on your reels:

  • Fire Frames: this is a simple, yet effective feature. Every symbol that radomly happens to be in a fire frame, will split in 2.
  • Dead Patient: here we are, not being much sentimental about dead patients. When 2 of those land on your reels simultaneously, a win multiplier is applied to the opossible winning combo on your reels. The value of the multiplier ranges from x5 to x9999
  • Enhancer Cells: at the bottom of the reels you see two cells with a count on them. They are counting fire frames, and ewhrn the meter reaches respectively 4/4 or 6/6 the cells will reveal either a Patient symbol or a Dead Patient Symbol.
  • Wild: represented by the skull, it is a regular Wild and substitutes for all other symbols but the scatter

xWays + xSplit + xNudge

On top of the reel modifiers that we have just seen, filling the meters with fire frames can also trigger one of the three special features Nolimit City is known for. Let’s have a look at them:

  • xWays: this increases the number of possible win ways on your reels. The xWays symbol reaveals one of the symbols on the paytable split in 2 or 3 – all but the scorpio, the spider and dead patient. If more than one xWays symbol appears anywhere in view, they will reveal the same one, thus increasing dramatically your chances of winning.
  • xSplit: you will see a deadly knife splitting symbols on your reels and doubling them.
  • xNudge Wild: this special Wild nudges on your reels, and every step it takes (for a max of 3) increases its win multiplier by +1. If there is more than one on your reels, all the win multipliers in view are added up, thus offering a huge win potential.

Nolimit Bonus

Among the most popular features in new online slots, the Bonus Buy feature offers direct access to the Free Spins bonus. No need to wait forever till the slot randomly offers this opportunity, you can buy into it. In order to do so, you need to press the star-shaped button on the left side of your reels and choose one of the following options:

  • Autopsy Free Spins: 8-11 Free Spins – 80x the stake
  • Lobotomy Free Spins: 9-13 Free Spins – 200x the stake
  • Menatl Free Spins: 10-15 Free Spins – 1000x the stake

Mental Free Spins

Free Spins is what every slot fan is really waiting for. And be prepared, because despite the huge win potential, in Mental this is not going to be pleasant. Let’s see what is going to happen to those patients in the mental ward while you have the possibility of winning huge amounts. The magic happens when during your regular game you manage to land 3 or more scorpion symbols – this awards 10 Free Spins.

There are several ways of improving your chances of hitting those big wins. Let’s see:

  • Autopsy Free Spins: you get there by landing +2 Spider Symbols. It also awards +2 extra free spins
  • Mental Free Spins: you upgrade to the last level by landing +1 Spider Symbol during the Autospsy free spins. On top of that, you get +1 free spins

Here you will also enjoy dead patient symbols – no reset of the win multiplier value during the feature. On top of that, on the last level of the free spins bonus round the Spider symbols are sticky and do not move from your reels, creating some interesting opportunities.
