Mental Features & Bonus Games

As is the case with all Nolimit City games, Mental is packed full of bonus features:

Fire Frames

Between one and 13 symbols can be randomly surrounded by flames in the base game. When a symbol lands within, the frame splits into two parts.

Dead Patients Feature

When two Dead Patients symbols land, the respective feature triggers. One of the patient symbols reveals one premium symbol with a multiplier between 5x and 9,999x the bet. The multiplier equates to the number of that symbol on the reel, as opposed to a win multiplier.

Enhancer Cells

Enhancer cells sit at the bottom of reels 2 and 4, which can be activated with four or six fire frames. Enhancer cells can activate one of the following modifiers when triggered:

  • Wild symbol

  • One patient

  • One dead patient

  • xWays (reveals three identical symbols)

  • xSplit (splits one symbol on each reel into two)

  • xNudge wild (nudges so the wild is fully visible on the reel, which increases the win multiplier)

Mental Transformations

The mental transformation feature triggers if a spider symbol lands on reel 2 or 4. Spiders can transform into xWays, xSplit, a dead patient, a wild, or a patient.

Autopsy Free Spins

The first bonus round in Mental is the Autopsy Free Spins round, which you can activate with three scorpion symbols in view. An additional spin is awarded if a scorpion lands in a fire frame. The bonus game begins with eight free spins, adding up to five frames to the grid.

Fire frames remain sticky throughout the feature, and you can upgrade to Lobotomy Free Spins when a spider symbol lands.

Lobotomy Free Spins

When you land three scorpions plus one spider, nine Lobotomy Free Spins are awarded. The same rules apply as in Autopsy Free Spins, but any spiders that land remain sticky throughout. The dead multiplier rule also applies, which sees the highest multiplier value from dead symbols collected.

When new patient symbols land, their multiplier is applied, and one is deducted from the dead symbols count. You can upgrade to Mental Free Spins with two spider symbols.

Mental Free Spins

To trigger Mental Free Spins, you need to land three scorpions and two spider symbols. This gives you ten Mental spins. Both spider symbols are sticky, and Mental transformations occur on each spin. What’s more, the dead multiplier count doesn’t decrease after its multiplier is transferred.

!!! This is Mental !!!

If the 66,666x max win is paid out, !!! This is Mental !!! has occurred!
