Mental is played on a 5-reel grid with a unique 3-2-3-2-3 layout, similar to Tombstone but more complex. This setup initially offers 108 ways to win, though the reels can expand to a maximum of 20 rows. Wins occur when three or more matching symbols land on adjacent reels, starting from the leftmost reel. The default RTP is 96.08%, increasing to a maximum of 96.47% when purchasing certain features. 

As expected, the game's volatility is rated Extreme, so brace yourself for an intense experience. Mental is available on all devices, with bet sizes ranging from 20 p/c to £/€100 per spin.

The eerie atmosphere deepens with its symbols, beginning with five lower-value body parts: skeletal hands, kidneys, hearts, brains, and eyes. The high-paying symbols feature five patients, referred to simply as Patient 1 through Patient 5. 

Landing five matching patient symbols awards payouts of 1.5x to 5x the stake. Now, let’s dive into the features.

Mental includes a range of special mechanics, including Fire Frames, Dead Patients, Enhancer Cells, Mental Transformations, Autopsy Free Spins, Lobotomy Free Spins, Mental Free Spins, and the ultimate “!!! This is Mental !!!” feature, along with four feature buy options.

Core Features

✅Fire Frames: On every spin, 1 to 13 positions randomly ignite with flames. Symbols landing in Fire Frames split into two, increasing potential ways to win.

✅Dead Patient: Triggered when two Dead Patient symbols land. This feature reveals a premium patient symbol with a random multiplier of x5, x10, x15, x30, x50, x100, x300, x500, x1,000, or x9,999. Unlike a traditional win multiplier, this value represents the number of that symbol added to the reels.

✅Enhancer Cells: Located at the bottom of reels 2 and 4, these activate when 4 or 6 Fire Frames appear on their respective reels. Once active, they reveal one of the following:A wild symbol
One of the five patient symbols
A regular Dead Patient symbol
xWays – reveals three identical symbols (excluding Scorpion, Spider, or Dead Patient)
xSplit – splits one symbol on each reel into two, then transforms into two wilds
xNudge Wild – nudges into full visibility, increasing a win multiplier by +1 for each step. If multiple xNudge Wilds land, their multipliers combine.

✅Mental Transform: Landing a Spider symbol on reels 2 or 4 triggers this feature, transforming it into one of the following: xWays, xSplit, Dead Patient, Wild, or Patient symbols.

With such a variety of features, Mental delivers an unpredictable, high-volatility experience where every spin can lead to something unexpected. Ready to take the plunge?
