Mental

The saved rules give 96.08% normal-play RTP. Evolution also lists a separate 94.20% provider build; do not combine that build with the paid-mode returns below.

Nolimit Bonus offers direct entries at 80×, 230× and 1,000× base bet, plus a 232× Lucky Draw. The saved €1 menu shows those same amounts in euros. The maximum base bet stated for feature purchases is €70.

The round maximum is 66,666× bet. Reaching the limit ends the round, including remaining feature activity.

The rules give a simulated maximum-payout probability of approximately one in 18 million rounds. That is a simulation measure for the top payout, not a general win or bonus frequency.

Wilds substitute for ordinary paying symbols but not Scorpions, Spiders or Dead Patients. Adjacent-reel wins run from the leftmost reel.

Read Patient values together with their reel-count role. A large Dead Patient number increases symbol multiplicity; a qualifying ways result is still needed for a payout.

An xNudge Wild gains one multiplier step for each nudge needed to become fully visible. When several Wild multipliers apply, their values are added.

This Wild multiplier is separate from a Dead Patient symbol-count value and from the game’s total payout cap.

Split entry symbols count once

A split Scorpion or Spider is one trigger symbol; its Fire Frame can separately add a starting spin.

No standard Scatter retrigger

Scorpions do not appear in Free Spins, and Spiders do not appear in Mental Free Spins. Upgrades and entry additions have their own rules.

Patient value is not cash

The 9,999 Dead Patient value is a symbol-count effect; it is not an automatic 9,999× award.

Mental suits players who enjoy learning how one feature changes another. The visible Fire Frame thresholds and three linked bonuses reward attention to the board state.

The cost is complexity: Patient values, Counts and Wild multipliers need separate interpretation. Players who prefer a single, immediately readable bonus may find the layered rules demanding.

Autopsy to Lobotomy

Remaining spins continue with the sticky Fire Frame state and a new sticky Spider. Dead Multiplier tracking becomes part of the stronger feature.

Lobotomy to Mental

The second sticky Spider is added and the Dead Multiplier state carries forward. Counts stop decreasing on transfer, changing how often a stored value can remain useful.

Each Patient type has its own stored value and Count. One Patient’s record is not a global multiplier for all five symbols.

The example below follows the rules’ Patient-1 illustration; it is not a recorded spin or a prediction.

A sticky Spider repeatedly opens access to the transformation outcomes: xWays, xSplit, Dead Patient, Wild or Patient. It does not mean every one of those effects occurs on every spin.

The difference from a newly landed base-game Spider is persistence: the source remains for later Free Spins.

The reel-2 cell activates at four Fire Frames, before the reel-4 cell at six. Track these separately when reading the bottom of the board.

Frames therefore affect both symbol density and access to additional symbol types. A new frame can matter even when its immediate split does not create a paying combination.

Begin with the frame positions and the two Enhancer counters. Then identify which effect was revealed before interpreting the changed reel height or multiplier.

In Lobotomy, watch a Patient’s Count decrease when its stored value transfers. In Mental, the same transfer leaves the Count available. That contrast explains the top bonus more clearly than its name alone.

The largest figures on screen describe different things. A 9,999 Patient value changes symbol multiplicity. The 66,666× figure is the round payout limit. One in 18 million is the stated simulated probability of that limit.

None of these establishes how often an ordinary win or a Free Spins trigger occurs.

Use the game’s normal-play RTP when comparing its base configuration. The saved version states 96.08%; the provider also lists a 94.20% build.

The 96.26%, 96.17%, 96.68% and 96.42% figures belong to the separate Autopsy, Lobotomy, Mental and Lucky Draw purchases. A higher listed buy RTP does not remove the much larger amount risked at entry.

Do frames survive an upgrade?

The stronger Free Spins modes retain the sticky Fire Frame mechanic alongside the added Spider state.

Does a transformed Patient use its stored value?

The rules exclude Patient symbols revealed through Dead Patient from the normal stored-value transfer.

Does xSplit copy a stored multiplier?

A newly split copy does not inherit the Dead Multiplier, keeping symbol subdivision separate from the stored record.
