Graphics
Set in a nightmarish Victorian-era psychiatric asylum, Mental delivers genuinely disturbing visuals with flickering lights, sepia tones, anatomical sketches, and deeply unsettling imagery. The symbols feature disturbingly detailed patients and dissected body parts that create an atmosphere of dread.
The slithering soundtrack, combined with creaking asylum sounds, creates one of the most psychologically intense atmospheres ever seen in a slot. This isn’t entertainment that makes you smile – it’s designed to unsettle and disturb in ways few slots dare attempt.

Conclusion
Mental is Nolimit City at their most extreme and daring, creating a slot that pushes every boundary – thematic, mechanical, and psychological. The 96.08% RTP is competitive, and the 66,666x max win potential is genuinely life-changing. However, this game isn’t for everyone.
Our main criticism is the overwhelming complexity – the feature system is so intricate that even experienced players need extensive demo play to understand it fully. The dark subject matter and disturbing visuals may be too intense for many players who prefer lighter entertainment.
Mental requires commitment, mental fortitude, and a strong stomach. If you can handle the darkness and complexity, you’ll find one of the most innovative and rewarding slots ever created. Just don’t say we didn’t warn you.
