Mental Free Demo Play

Once again overstepping the bounds of reasonableness, developers Nolimit City tackle a spooky and repulsive theme to say the least in the Mental slot released in August 2021. This horrific casino game invites you to enter a psychiatric hospital, the kind of place where no one really dares to go that even urban exploration fanatics will refrain from.

Mental - Slot Review


Mental is a 5 reel slot with 108 ways to win by default. The volatility is extreme and the RTP is 96.08% but can go up to 96.68% during the Mental bonus. You will start the game by betting anywhere from $0.20 to $70 per spin.

You will discover the organ symbols as low-paying symbols and get to know the five patients as high-paying symbols.

  • Enhancer Cells: Located at the bottom of reels 2 and 4, these positions are active with 4 to 6 Fire Frames. When active, the Enhancer Cells reveal one of these special symbols: a Patient Symbol, a Dead Patient, the xWays symbol, xSplit, the Wild which can replace all standard symbols or the xNudge Wild;
  • Mental Transform: When you find a spider symbol on reels 2 and 4, you activate the feature, the spider will transform into one of the special symbols: xWays, xSplit, Dead Patient, Wild or Patient.

You’ll certainly need to have a strong mind to go through with Nolimit City Mental slot, because while its environment is just plain creepy, its features are still hard to digest, at least it will take you a while to grasp all the concepts properly. It will also take you a few hours to come down from a game session on Mental no matter how much you win or lose.
