Mental II Demo & review

If you liked the original asylum, Mental II (searched mostly as Mental 2) keeps its Dead Patient multipliers and three tiers of free spins, then adds xHole, xMental and xGod, a symbol that pays the game's cap outright when one lands on every reel. Nolimit City released the sequel in March 2025. It is built for bonus buyers with a deep balance, and its own volatility label, Insane, is not an exaggeration.

The base game at 108 ways before a spin, with the Enhancer Cells under the middle reels. FluxPlays demo test, 31 October 2026.

How Mental II works

Each spin starts at 108 ways on a 3-2-3-2-3 grid, and wins pay on adjacent reels from the left, the best win per way only. Five Patient symbols sit above five Skeletal ones, and the top Patient pays 2.50 for five at a 1.00 bet, so the paytable alone is small. Everything that matters comes from features that split symbols, add ways or attach multipliers.

The demo plays in euro credits, which we treat as dollars.

Fire Frames, Enhancers and the x-features

How the base game's pieces feed each other:

1. Fire Frames and Fire Reels turn up at random: a symbol in a Fire Frame splits in two, and every symbol on a Fire Reel splits in three, so the ways count jumps.
2. Enhancer Cells under reels 2, 3 and 4 open once enough Fire Frames land above them, revealing a Wild, xSplit, an xNudge Wild, a Patient symbol or xWays.
3. Dead Patients. Two or more reveal one Patient symbol with a random multiplier, from x5 up to x9999.
4. Special symbols landing in a Fire Frame or Fire Reel set off the big features below.

The Dead Patient multiplier carries the free spins. In the base game, the fire cells and the ways they create are what you watch for.

How the bonuses trigger

Three Cognitive Scatters, one each on the first, middle and last reels, start the free spins, and Disembodied Scatters on reels 2 and 4 decide the tier. Every Scatter that lands in a Fire Frame adds one spin, and in a Fire Reel two.

Bloodletting Spins

Three Cognitive Scatters alone give eight spins in which Fire Frames and Fire Reels are sticky. A Disembodied Scatter landing during the round upgrades the remaining spins to Surgery or Experimental Spins.

Surgery Spins

One Disembodied Scatter with the three Cognitive ones gives nine spins. The Disembodied symbol sticks and sets off Mental Transform every spin, and Dead Patient multipliers are collected with a counter and passed to later Patient symbols.

Experimental Spins

Two Disembodied Scatters give ten spins. Both stick, and the collected Dead multiplier's counter never goes down, so a big multiplier stays until the last spin. This is the tier the game is built around.

Our bought Surgery Spins three spins in, with x5 Patients and a collected x10 Dead multiplier. FluxPlays demo test, 31 October 2026.

Bonus buy and Nolimit Booster: prices and what you get

Nolimit Bonus buys one round. A Nolimit Booster changes every spin it is switched on for, at a price per spin.

The game shows one volatility label, Insane, for every option. The xMental Booster costs more per spin than ten spins of the demo balance allow at a 1.00 bet, so we played it at the 0.20 minimum, 640 a spin.

The buy panel in our demo session: five bonus buys and four boosters. FluxPlays demo test, 31 October 2026.

RTP, volatility and max win

The base game returns 96.06% by the rules, and every buy and booster sits slightly above it. Nolimit labels the volatility Insane. Wins top out at 99,999x the bet, and a round ends as soon as its total reaches it. Nolimit simulates that at about 1 in 16 million rounds. In God Mode, once xGod lands, only xGod and Spider symbols, which carry no value, can appear, so a spin that falls short of five xGods can end with nothing.

Mental II vs Mental: what changed

The Dead Patient multiplier and the three-tier structure carry over. What the sequel adds is a set of ways to pay for its most extreme moments directly.

Our demo test: 100 spins, five buys, four boosters

The ways count made our base game. Two spins paid most of its return, both after xWays reveals stretched the reels: spin 15 reached 7,491 ways, and spin 79, at 4,200 ways, paid $57.60. Most other wins were small change.

Every bought free spins round returned less than half its price, Experimental Spins included. The boosters told a different story. Half of the ten xHole spins paid more than their price, and one ended on 107,520 ways. At the 0.20 bet, the ninth xMental respin grew to 313,600 ways with an x12 xNudge Wild and hit the cap: $19,999.80. God Mode landed xGod on two reels and Spiders everywhere else, paying nothing. Natural free spins never came, so the bonus trigger is described from the rules. One session like this shows how far apart the results can sit, not what any option returns over time.

Base spin 79 settled at 4,200 ways, our best base spin. FluxPlays demo test, 31 October 2026.

An xHole Booster spin settled at 107,520 ways for $113.60 against its 99 price. FluxPlays demo test, 31 October 2026.

Is Mental II worth playing?

Only if you play it through its paid options. The base game is a wait for the ways count to explode, and natural free spins come rarely. The buys and boosters are where the sequel earns its place: Experimental Spins keep a Dead multiplier for the whole round, xHole turns a single spin into tens of thousands of ways, and xGod puts the cap on any spin.

Pick Mental if you want the same asylum with cheaper buys and a lower ceiling. Mental II is the choice when you want more ways to chase the top, and a balance that can survive the misses.

In the demo, start with ten xHole Booster spins. They show the game's biggest mechanic on every spin, at a fraction of the top buy's price.
