Mental in brief

Mental is one of Nolimit City's most notorious slots: disturbing asylum theme, layered modifiers and a 66,666x max win. The base game is frequently quiet, and the bonus can either fizzle or explode depending on how multipliers stack. It's exactly the kind of game that's worth learning in demo mode first – the feature interactions take a few bonuses to understand.

Mental II in brief

Mental II returns to the asylum on a 3-2-3-2-3 grid. Fire Frames split one to thirteen random positions into two, and Enhancer Cells under reels 2 to 4 switch on as more frames appear. Two Dead Patient symbols reveal a patient with a multiplier from x5 up to x500.
