RTP builds

Mental is sold to casinos in more than one configured return, and the operator picks the one it runs. Most sites print a single figure, which is simply wrong for anyone playing a different build.

About Mental

Mental is a Nolimit City slot from 2021, built on an irregular five-reel layout of three, two, three, two and three positions for 108 ways to win. Its reputation is for two things: a deliberately unpleasant asylum theme, censored in some markets, and a feature set dense enough that a first session is mostly spent working out what just happened. The base mechanic is the Fire Frame. Between one and thirteen positions can be surrounded by flames, and a framed position splits the symbol landing in it into two. The second and fourth reels carry Enhancer Cells at their bottom position, activated by four or six Fire Frames respectively, and each grants one of six modifiers to the spin. The Dead Patient feature fires when two Dead Patient symbols land: one converts into a premium patient symbol carrying a value from 5x up to 9,999x, which counts as a number of symbols rather than as a win multiplier — a distinction worth knowing before reading the paytable. Free spins come in three tiers, and each is the tier below it plus more: Autopsy from three scatters, Lobotomy from three scatters and a spider, and the Mental round above both, with sticky frames and collected multipliers carried through. The 66,666x cap belongs to the top tier. The full rules and the buy cost, where offered, are set out in the game's own information panel.

Mental: common questions

What is the RTP of Mental?

The studio default for Mental is 96.35%, but the game is also sold to casinos at 96.09%. Which build runs is the operator's choice rather than yours, so check the game's own info screen before you play.

What is the maximum win in Mental?

Wins in Mental are capped at 66,666x your stake. That is the ceiling of the game's maths rather than a typical outcome — reaching it is rare.

How volatile is Mental?

Mental is a high-volatility game: wins land less often and the gaps between them are wider, so a bankroll that survives long dry spells matters more here than it does elsewhere.

Can you buy the bonus in Mental?

Yes — Mental has a bonus buy: you pay a fixed multiple of your stake to start the bonus round instead of waiting for it. Whether it is offered depends on the casino, and the buy is banned outright in several markets.

What are the minimum and maximum bets in Mental?

Stakes in Mental run from 0.2 to 70 per round, in whatever currency your casino uses. Individual casinos can narrow that range.
