How Mental plays
Fire Frames land on 1 to 13 random positions and split the symbol inside them in two, and landing four or six frames opens Enhancer Cells that can add xWays, xNudge or xSplit effects. Two Dead Patient symbols can award a random multiplier from x5 to x9999 on a patient symbol, and a Spider symbol transforms symbols. Three Scorpions start Autopsy Freespins with sticky Fire Frames; adding one or two Spiders upgrades to Lobotomy or Mental Freespins.
Theme: Psychiatric asylum, horror (sepia-toned). Filed under Horror and dark.
Features in this game
- xWays: A Nolimit City mechanic where special symbols reveal several copies of one symbol, multiplying the number of ways to win on that spin.
- Nudges and holds: Fruit-machine features that let a reel move one position (nudge) or stay put while others spin again (hold).
- Multipliers: A value such as ×2 or ×10 applied to a win, a spin or a whole feature, multiplying the amount paid.
- Free spins: A bonus round of spins played at no extra cost, usually triggered by scatter symbols and often with extra features.
What the figures mean
An RTP of 96.08% is a long-run average across millions of spins. It works out at a house edge of 3.92%, so every £100 staked costs £3.92 on average. A session of 200 spins at £1 stakes £200, and the expected cost of that session is £7.84, although the real result will usually land a long way either side. Work out your own figures.
The provider rates volatility as Extreme (10). That describes how winnings are spread: higher volatility means longer runs with little back and rarer, larger wins. It does not change the average. More on volatility, or see it in a simulation.
Published hit frequency is 34.19%, meaning roughly 34 spins in every 100 return something. Many of those returns are smaller than the stake.
