FIRE FRAMES & FIRE REELS

Fire Frames
In the base game, between 1 and 13 random reel positions can transform into Fire Frames. When a symbol lands inside a Fire Frame, it splits into 2 separate parts.

Fire Reels
During gameplay, 1 to 5 reels may randomly turn into Fire Reels. Any symbol landing on a Fire Reel splits into 3 parts instead of one.

DEAD PATIENTS

This feature activates when 2 or more Dead Patient symbols appear. It selects one of the Patient symbols and assigns it a random multiplier: x5, x10, x15, x30, x50, x100, x200, x500, x1000, or x9999. The multiplier amount corresponds to the number of that symbol present on the reel.

ENHANCER CELLS

Enhancer Cells are positioned at the bottom of reels 2, 3, and 4. The number of Fire Frames that appear determines how many cells become active:
-4 Fire Frames activate the Enhancer Cell on reel 2.
-6 Fire Frames activate the Enhancer Cells on reels 2 and 4.
-8 Fire Frames activate all three Enhancer Cells (reels 2, 3, and 4).
For activation purposes, a Fire Reel counts as 2 or 3 Fire Frames, depending on the reel’s height. Each active Enhancer Cell can reveal one of the following symbols:
Wild
The standard Wild symbol.
xSplit
Duplicates one symbol on every other reel, doubling those symbols, and then splits itself into 2 Wilds.
xNudge Wild
Always nudges until it becomes fully visible on the reel. Each step it nudges increases the win multiplier by +1. Multiple Wild multipliers stack together into a total multiplier. If an xNudge Wild is affected by xSplit, its multiplier increases by +1.
Patient Symbol
One of the five available Patient symbols.
xWays
Reveals 3 matching symbols and increases the reel height. Can reveal any paying symbol. If more than one xWays appears, all of them reveal the same symbol.

xHOLE

The xHole feature activates when the xHole symbol lands inside a Fire Frame or on a Fire Reel in the middle position of the third reel. When triggered, only standard paying symbols and the Wild symbol are taken from the main reels and redistributed to random positions. Their current sizes are then multiplied by 2, 4, or 8. If an xNudge Wild is involved, only its win multiplier is affected. After the effect resolves, the xHole symbol turns into a Wild. Any winning symbols that existed before the xHole effect are returned to their original positions afterward. If the xHole symbol lands outside a Fire Frame or Fire Reel, the feature will not activate. Stored Dead Patient multipliers are not applied during the xHole feature.

xMENTAL

The xMental feature is triggered when an xMental symbol lands within a Fire Frame or on a Fire Reel anywhere on the reels. When activated, it awards an extra spin and applies the following effects:
-Every reel position becomes a Fire Frame.
-Enhancer Cells reveal either xWays, xNudge Wild, or xSplit.
-There is a chance to activate the xHole feature.
If the xMental symbol appears outside a Fire Frame or Fire Reel, the feature will not activate. If an already active xMental symbol lands during a bonus trigger, the xMental feature will not be triggered again.

MENTAL TRANSFORM

The Mental Transform feature is activated when a Disembodied Scatter lands on reel 2 or reel 4 during the game. Once triggered, the Disembodied Scatter changes into one of the following symbols: xWays, xSplit, Dead Patient, Wild, or a Patient symbol.

SCATTERS

Cognitive Scatter symbols can appear only on reels 1, 3, and 5 during the base game.
Disembodied Scatter symbols are restricted to reels 2 and 4.

Scatter Combinations:
Landing 3 Cognitive Scatter symbols awards 8 Bloodletting Spins.
Landing 3 Cognitive Scatters together with 1 Disembodied Scatter triggers 9 Surgery Spins.
Landing 3 Cognitive Scatters and 2 Disembodied Scatters activates 10 Experimental Spins.

Additional Spins in Bonus Rounds:
Each Scatter symbol landing inside a Fire Frame grants +1 extra spin.
Each Scatter symbol landing on a Fire Reel grants +2 extra spins.

BLOODLETTING SPINS

During the Bloodletting Spins feature, all active Fire Frames and Fire Reels stay locked in place for the entire bonus round. If 1 Disembodied Scatter symbol appears, the remaining spins are upgraded to Surgery Spins and +1 extra spin is awarded. If 2 Disembodied Scatter symbols land, the remaining spins are upgraded to Experimental Spins and +2 additional spins are granted.

SURGERY SPINS

Along with the features available in Bloodletting Spins, the Disembodied symbol becomes sticky and activates the Mental Transform feature on every spin.
Dead Multiplier:
The highest multiplier revealed from each Dead Patient symbol is collected together with its corresponding “Count.” The Count represents how many of that specific Patient symbol have been revealed. For example, if three Patient (1) symbols appear with multipliers of x5, x10, and x15, then Patient (1) is collected with a Multiplier of 15 and a Count of 3.
Once collected, the Dead Multiplier is assigned to its matching Patient symbols according to the Count when a newly collected Patient symbol lands on the reels. For instance, if Patient (1) holds a Multiplier of 15 and a Count of 3, the first three occurrences of Patient (1) will each receive the x15 multiplier.
Each time a Dead Multiplier is applied to a Patient symbol, the Count decreases by 1. Dead Multipliers do not transfer to symbols revealed directly by a Dead Patient symbol.
Landing one additional Disembodied Scatter upgrades the remaining spins to Experimental Spins and grants +1 extra spin.

EXPERIMENTAL SPINS

In addition to all Surgery Spins mechanics, both Disembodied symbols become sticky and activate the Mental Transform feature on every spin. The Dead Multiplier Count assigned to Patient symbols no longer decreases after being transferred. Instead, it continues to accumulate as new Dead Patient symbols are revealed.

GOD MODE

Go after the Max Win (Death Is Just The Beginning) by landing an xGOD symbol on every reel. Activating this mode costs 6666x your current bet.

DEATH IS JUST THE BEGINNING

The maximum possible win in the game is 99,999x the base bet. If your total winnings exceed this limit, the round ends and you are awarded the full 99,999x payout. This maximum win can also be triggered instantly in the base game by landing one xGod symbol on every reel in a single spin.


How to Play Mental II

Mental II starts at a €0.20 minimum stake, scaling up to €100.00. The variable 3-2-3-2-3 layout means reel heights shift, creating dynamic win paths. Players spin normally or activate the Nolimit Booster at 1.4x bet to guarantee a Cognitive Scatter on reel 1. The Feature Buy option allows direct access to bonus gameplay. The base game randomly activates Fire Frames or Fire Reels, splitting symbols into 2 or 3 parts. The more Fire positions appear, the more Enhancer Cells activate on reels 2, 3, and 4. Dead Patient multipliers can stack and later transfer to Patient symbols. When 3 Cognitive Scatters land, Bloodletting Spins begin. Additional Disembodied Scatters upgrade the bonus into Surgery or Experimental Spins. Given its Insane volatility and 99,999x maximum potential, Mental II is designed for players who accept long dry streaks in exchange for extreme multiplier spikes. Understanding how Fire mechanics increase symbol density is key to mastering the slot.

Mental II Is Absolute Chaos — In The Best Way

I grabbed 100 free spins with a no deposit bonus just to test this madness, and wow… Mental II is dark. The asylum theme is creepy, the portraits feel intense, and the whole thing screams volatility from the first spin.
The Fire Frames mechanic is wild. Watching symbols split into 2 and sometimes 3 parts completely changes the board. I hit 5 of the top restrained patient symbol for 2.5x — small by itself — but when Dead Patient multipliers started appearing, that’s when things got spicy. I saw multipliers all the way up to x100 during one bonus. My heart literally stopped when two Dead Patients landed together.
Triggered Bloodletting Spins once. It upgraded to Surgery Spins after a Disembodied Scatter landed, and that’s when the tension really kicked in. The volatility is insane — long dry streaks, then sudden bursts.
It feels brutal, risky, and honestly… addictive. I’d definitely play it again, but only with a bonus. This slot doesn’t play around.
