Inside the game

Captured in the studio's own free demo on 14 September 2026. Nothing below is taken from a press release or another site — it is what the game shows when you open it.

The base game — Mental — The base gameThe five reels alternate three and two cells — three on the left, then two, three, two, three — under a bare bulb, in the tiled corridor of an old asylum. A "Ways 108" plate tops the second reel, an xSplit / xNudge logo the fourth, and two cells reading 1/4 and 1/6 close the bottom of those same two columns. The symbols are sepia patient files numbered PATIENT-1 to PATIENT-5, an eye, a brain, a heart and a skeletal hand. Bet at €1, balance €10,000, PLAYING FOR FUN notice.

Game rules, page 1 — Mental — Game rules, page 1The first page of the panel lists seven features — Fire Frames, Enhancer Cells, Mental Transform, Autopsy Freespins, Lobotomy Freespins, Mental Freespins, This Is Mental — then gives the specification: "A 5-reel, up to 20-row video slot with 14 symbols", "108 win ways by default", a theoretical return of 96.08% for this game followed by four feature buys, and a simulated maximum payout of 66,666 times the bet, quoted at one round in 18,000,000. The Wild substitutes for everything except Scorpion, Spider and Dead Patient.

Game rules, page 2 — Mental — Game rules, page 2The pay table opens on the "Patient Symbols" section: five sepia files numbered PATIENT-1 to PATIENT-5, in descending order. The first pays 5.00 for five, 1.50 for four and 0.75 for three, then come 3.75, 2.50, 2.00 and 1.50 for five, the last dropping to 0.40 for three. No other symbol appears on this page, and the values are in the currency of the bet, here €1.

Game rules, page 3 — Mental — Game rules, page 3The panel has been scrolled: the list picks up at "108 win ways by default", the five theoretical returns and the simulated maximum payout of 66,666 times the bet, then details the feature rules — a split Scorpion/Spider symbol counts as 1 towards the free spins trigger, no Scorpion lands in Freespins, no Spider in Mental Freespins, and the Dead multiplier won on the trigger carries forward into the Lobotomy and Mental Freespins.
