Mental

A symbol lands carrying a multiplier that applies to the win it takes part in, or to the whole spin.

What it means for you: Concentrates the return into rarer spins. The same RTP feels far more volatile than a game without one.

Landing two Dead Patient symbols in the same spin awards a random multiplier of between 5x and 9999x, applied directly to that spin rather than banked and paid out later.

A triggered round of spins that costs nothing and usually changes the maths.

What it means for you: Where most of the return lives in modern slots. How long it takes to reach is the feature frequency.

Three Scorpion symbols trigger Autopsy Freespins, a bonus mode with sticky Fire Frames. Landing a Spider symbol alongside the three Scorpions instead triggers Lobotomy Freespins, an upgraded round where the Spider stays sticky, a Mental Transform fires on every spin, and a Dead Multiplier carries onto a Patient symbol. Three Scorpions plus two Spider symbols trigger the top tier, Mental Freespins, where the Spider symbols stay sticky and the Dead Multiplier never decreases.

The free-spins round can be bought outright for a fixed multiple of the base bet, skipping the wait.

What it means for you: Compresses a long session into one purchase, and usually at a different RTP from the base game.

The Nolimit Bonus feature buy enters one of the game's bonus rounds directly, at a stated cost of 80x to 1000x the base bet depending on which tier is bought. The studio's page notes the feature may be removed in some regulated markets.

After the reels stop, one symbol type is converted into another across the grid: low-pay to high-pay, or everything to a single symbol.

What it means for you: Produces a large win from a spin that looked dead, which is why it is used in markets where session length is short.

Whenever the Spider symbol lands on the reels, other symbols on the grid transform, changing the outcome of that spin.

A Nolimit City trademark. A special symbol unpacks into between two and twelve copies of one revealed symbol, which changes the row count of the reel it sits on and so changes how many ways that spin has.

What it means for you: Produces the studio's signature outcome: a spin that is either nothing or enormous, with little in between.

The second engine the intro copy pairs with xNudge for this title. Landing 4 or 6 Fire Frame positions activates Enhancer Cells, which improves its odds of appearing too.

A Nolimit City trademark. A symbol splits every other symbol on its reel, or on the whole grid, into two. Positions double, and where multipliers are already on the grid they compound.

What it means for you: The clearest example in the catalogue of a mechanic whose whole purpose is the tail of the distribution.

Listed as a third Enhancer Cells booster alongside xWays and xNudge once Fire Frame positions activate, though the studio's intro sentence for this title names only the other two as headline engines.

A Nolimit City trademark. An oversized wild nudges into full view one position at a time, and its multiplier increases by one for every position it moves before it lands.

What it means for you: Ties a growing multiplier to a visible, legible event rather than a hidden roll, and it plays strongly high-volatility in practice.

One of the two engines the studio's own intro copy names for this title, paired with xWays. Its Enhancer Cells feature makes it more likely to land once 4 or 6 Fire Frame positions are active.
