About Mental

Mental – a hospital full of disordered and psycho patients.

Nolimit City is known for creating unique and extreme slots. Extreme when it comes to the variance and the win potential. Unique when it comes to the gameplay and the theme.

This slot, Mental, fits perfectly in that category. The win potential is insane, and the theme is exemplary and even somewhat intimidating.

The action takes place in a hospital with completely disordered and deranged patients.

It reminds us of One Flew Over the Cuckoo’s Nest (starring Jack Nicholson) and even The Silence of the Lambs (Anthony Hopkins).

Mental RTP

The main game has a default RTP of 96.08%, and if you decide to buy the most expensive free spins option (Mental Free spins), you’ll play with a default RTP of 96.68%.

It would help if you were careful, though, as Mental comes with two versions. Some casinos offer Mental with an RTP of 96.08%, but others do so with a lower RTP of a mere 94.20%.

What is the best Mental casino?

It’s a waste of money to play the lower-paying version of Mental, so you need to check the game rules of your casino before you play.

You can also let the Wizard do the work for you, who has already selected all the casinos with the 96.08% RTP version.

You also see which casinos you need to avoid, as these offer the lower RTP version.


Gameplay and features

Mental has 5 reels and a 3-2-3-2-3 setup. Perhaps uncommon, but that’s what Mental is all about.

  • It’s a win-all-ways slot, with at least 108 ways to win.
  • Symbols can (occasionally) split into two.
  • There are also some enhancer cells, creating additional symbols on the reels.
  • All in all, getting tens of thousands of win ways is possible.
  • The premium symbols are the five numbered Patient Symbols.
  • We have the Organ Symbols as the lows.
  • The gold-colored skulls are the Wilds.

You’ll also note the gold-colored Tomb Stones or “Dead Patient” symbols.

Land one of these, and these transform into a Patient Symbol with an x5, x10, x15, x30, x50, x100, x200, x500, x1000, or even an insane x9999 multiplier.

You trigger the Mental Transform feature if you manage to land the so-called Spider symbols on reels 2 and 4. In that case, both Spider symbols transform into an xWays, xSplit, Dead Patient, Wild, or a Patient symbol.

If you thought it was complex, you’re right. And it gets even more so, as we also have three free spins options: The Autopsy Free spins, Lobotomy Free spins or the Mental Free spins.

  • To trigger these, you need to spin Scorpion symbols.
  • You can also use the Bonus Buy feature (Nolimit Bonus feature) to activate these.
  • The cost is 80x, 230x, or a monstrous 1000x the original bet.
  • If you like to gamble, you can select the Lucky Draw Free Spins option (cost: 232x). In that case, you trigger one of the three free spins options as described.

What is the max win on the Mental slot?

It’s probably a “no-brainer” that we’re talking about an extremely high variance slot. The maximum in is a flabbergasting 66,666x the stake. The chances of winning it are 1 in 18 million spins.

If you have a big bankroll, you can opt to buy the Mental Free spins, which is the way to get a fair chance at winning something in the tens of thousands of times the bet. Be aware: this slot is very volatile, and your money can evaporate quickly if you find yourself on the wrong side of the variance.

CasinoWizard’s verdict: 4 out of 5 stars

Nolimit City has done everything within its capabilities to pull out something extraordinary.

The unequaled theme, the mysterious and “psychotic” characters, and the outrageous win potential make this slot one to remember.

However, this isn’t a slot for novice players or risk-avoiding players. It’s incredibly volatile and complex. Bear that in mind before you enter the hospital!
