Review

Overview

Mental is set in a dark asylum environment where most of the focus is on special mechanics and bonus modes. The base game introduces the core symbols and features that later connect to Free Spins.

Progress through the game is tied to triggering different bonus rounds, some of which can upgrade into stronger versions. This creates a structure where the main game prepares the ground for larger events later on.

Gameplay

Gameplay is based on standard spins with added mechanics that affect how symbols behave on the reels. xWays and related mechanics change the number of winning paths during play.

Most of the interaction comes from watching features activate and bonuses upgrade. The game clearly signals when special symbols land and when new bonus modes are triggered, helping players follow what is happening despite the many elements involved.

Bonus features

The game includes several Free Spins modes that are triggered by Scorpion and Spider symbols. These bonus modes can upgrade into stronger versions, adding sticky symbols, symbol transformations, and persistent multipliers.

Additional features like Dead Patient multipliers and symbol transform mechanics can apply during bonuses, with some bonuses carrying effects forward until the round ends. A Feature Buy option allows direct access to selected bonus modes where available.

Volatility and bankroll

Mental is listed as an extreme volatility slot with a value of 34.19%. Wins are primarily connected to bonus rounds and special features rather than regular base game spins.
