Mental Features & Bonus Games
As with all Nolimit City games, Mental is packed with bizarre and exciting features to keep you engaged. Here’s what to look out for:

If you land two Dead Patients symbols, the feature activates. One of the patient symbols will reveal a premium symbol with a multiplier ranging from 5x to 9,999x your bet. This multiplier will increase based on the number of that symbol present on the reel, rather than functioning as a standard win multiplier.
3. Enhancer Cells
Located at the bottom of reels 2 and 4, Enhancer Cells can be activated with four or six fire frames. When triggered, they can activate one of the following modifiers:
Wild Symbol
One Patient Symbol
One Dead Patient

xSplit (Splits one symbol into two on each reel)
xNudge Wild (Nudges the wild to ensure it's fully visible, increasing the win multiplier)

xWays
xSplit

-Wild -Patient
5. Autopsy Free Spins
To trigger Autopsy Free Spins, land 3 Scorpion Symbols on the reels. You’ll begin with 8 free spins, and the fire frames will be added to the grid. As you progress, the fire frames stay sticky, and landing another Scorpion Symbol in a fire frame grants you an additional spin. If you land a Spider Symbol, you can upgrade to Lobotomy Free Spins.
6. Lobotomy Free Spins
Trigger Lobotomy Free Spins by landing 3 Scorpions and 1 Spider symbol. This gives you 9 free spins. Similar to the Autopsy Free Spins, the Spider Symbols remain sticky throughout. Dead Multipliers also stay in play, with the highest multiplier value from the collected Dead Patient symbols transferred to new Patient Symbols as they land.
7. Mental Free Spins
To trigger Mental Free Spins, you’ll need 3 Scorpions and 2 Spider Symbols. This gives you 10 spins, with both Spider Symbols staying sticky throughout the feature. During each spin, the Mental Transformations feature occurs. Furthermore, Dead Multipliers do not decrease after they’re transferred, ensuring you keep the potential for bigger wins alive.
