Mental Theme


Playing this slot might not be a good idea if you want to get a good night's sleep. Its difficulty is so high that reading its review and watching its gameplay are equally insane.

It also uses Evoplay's advanced game engine, Spinential, which delivers 10x faster loading times, and an improved user interface for a truly incredible gaming experience.

Bonus Rounds & Free Spins


The slot awards 8 spins for 3 landed Scorpion Scatter. Every Scatter that lands in the Fire Frame gives an extra free spin. Up to 5 random positions are enhanced with Fire Frame. 

Lobotomy Free Spins feature is triggered when 3 Scorpion Scatter lands on the board along with 1 Spider Scatter. You will receive 9 free spins. This feature is based on the rules of the lower-level attack function. All dropped symbols during this feature become Sticky, activating the Mental Transformation feature with each spin. The highest multiplier is collected and applied to the new symbol.

Having landed 2 Spider symbols, the slot triggers the Mental Free Spins feature. This feature is triggered from the main game if you win 3 Scorpion Scatters and 2 Spider Scatters at the same time. This gives 10 free spins, and the "Mental Transformation'' Spider symbol is also displayed here. Also, the counter of the Dead Multiplier does not decrease by 1 when transferred to a new Patient symbol, unlike the previous feature.

Mental - Online slot

Mental Max Win

The maximum win is 66,666 times the stake.
The potential of 66,666 times the stake can be achieved when this thing works at least at 20%. When testing this game, we felt its power and the power of the free spins feature that will allow you to get the maximum win.
overall rating:
You can take this torture and make sense of everything that happens when this game works to its fullest (or at least half). Honestly, this slot is the hardest, most confusing, and disturbing we've ever seen! The visuals are terrifying but well done and accompanied by an intense horror soundtrack that gives you goosebumps. You'll need to clear your head after your Mental session so keep some light-heart fruit game on hand. 
Fire Frames split symbols
A large multiplier of the Dead Patient symbol
Six modifiers
Three levels of the Bonus Round
Very scary design/soundtrack
