Mental has a standard layout of three reels and five rows. The structure of the slot’s grid follows a 3-2-3-2-3 pattern. That said, it can have up to twenty rows, depending on the extent of bonus features you trigger.

The case is the same for the number of possible ways to win, which starts at 108, but can be boosted several times over depending on additional features that are currently active.

The Best Bonus Feature of Mental Slot Machine

Mental includes several bonus features that enhance the experience and provide additional value. The first is the Fire Frames feature, which splits any symbol that gets into the frame into two separate symbols. This feature can further be enhanced by Enhancer Cells.

When activated by a minimum of four Fire Frames, the Enhancer Cells Mental bonus game can reveal one of these random possibilities:

  • One of the five patient symbols.
  • The Dead Patient symbol.
  • xWays, which would reveal three symbols (except Dead Patient, Spider, or Scorpion).
  • xSplit, which would split on each reel and split itself into two Wild symbols.
  • Wild symbol.
  • xNudge Wild, which further increases the multiplier.

Mental Symbols & Payouts

Mental has ten standard symbols. Five are represented by different patients, while five have organ and body part symbols. To make a winning combination, you need at least three matching symbols.

The skeleton hand is the lowest-valued symbol, paying only your original bet back for five matching symbols. Patient no. 1 is the highest-valued icon, paying 5x your base bet for five symbols.

There are also several special symbols. Firstly, the Spider symbol triggers Mental Transform and transforms into a Dead Patient, Wild, xWays, xSplit, or regular patient symbol.

A very valuable Dead Patient symbol reveals one of the regular patient symbols but with a rewarding multiplier. The symbol awarded with this feature can have a maximum multiplier of up to 9,999x.

Lastly, depending on the number of Spider and Scorpion symbols on the reels, you can win the following number of Mental free spins:

  • Autopsy Free Spins – 8 free spins for 3 Scorpion symbols.
  • Lobotomy Free Spins – 9 free spins for 3 Scorpion symbols and 1 Spider icon.
  • Mental Free Spins – 10 free spins for 3 Scorpion symbols and 2 Spider icons.

How to Play Mental

The Mental slot game is as simple to play as any other game of its kind. To play, all you need to do is select your bet size and press the spin button. You can choose from 25 pre-set betting sizes, ranging from $0.20 to $100.

This slot includes a very intuitive auto-spin feature, which allows you to pick anywhere between 10 and 1000 automatic spins. You can also add stop limits based on your overall balance or how much you win. Additionally, there’s the option to have the reels spin significantly faster if you stick with manual gameplay.

Mental Game RTP & Volatility

The listed Mental RTP is 96.08%. This is in line with the industry average and with the RTP numbers most Nolimit City slots come with. The game also lists the RTP of each feature:

  • Autopsy Feature – 96.26%
  • Lobotomy Feature – 96.17%
  • Mental Feature – 96.68%
  • Lucky Draw – 96.42%

With this in mind, if you want to get the most from your money long-term, these percentages might be a bit low, as you can find more favorable games in this regard.

Additionally, Nolimit City lists this slot as having “Insane Volatility”. Needless to say, this means that the slot’s volatility is very high and that the game is not the best pick for casual players or those with a smaller bankroll. While it can pay out massive wins, these payouts are often far between.
