Mental: 96.08% published RTP, extreme volatility, 66,666x max win

Mental: our verdict

Nolimit City's asylum slot, with xWays, xNudge and xSplit on one board, Dead Patient multipliers from x5 to x9999, and a 66,666× ceiling at 96.08% and extreme volatility.

Why it is on the list

Mental stacks three of Nolimit City's xMechanics on one board (xWays, xNudge and xSplit) and builds its identity on a fourth feature, the Dead Patient. From the studio's own page: whenever two Dead Patient symbols land, a random multiplier from x5 to x9999 can be applied to a patient symbol. Any symbol landing in a Fire Frame splits into two parts, and collecting fire frames unlocks the Enhancer Cells. The Spider symbol triggers Mental Transform, a symbol-transform feature. Released 31 August 2021.

How it plays

The bonus is a ladder, per Nolimit's feature notes. Three Scorpion symbols trigger Autopsy Freespins, with sticky Fire Frames. Three Scorpions plus a Spider give Lobotomy Freespins, where the Spider is sticky, awards Mental Transform on every spin, and a Dead Multiplier is transferred to a Patient symbol. Three Scorpions and two Spiders open Mental Freespins, where the Spiders are sticky and the Dead Multiplier never decreases. The lower rounds may be upgraded as they play out, so every Spider matters.

The maths

Nolimit publishes one return on the game page: 96.08%, with no statement on lower builds. The page splits it as 58.16% from the base game and 37.93% from the bonus. Volatility is extreme. Max win is 66,666× the bet, and the page states that reaching it ends the game round. The studio lists a bet range of €0.20 to €70 and a feature buy from 80× to 1,000× the bet, which it notes may be removed in some regulated markets.

Who it is for

Players who want Nolimit at full intensity and accept the long dry stretches extreme volatility brings. The appeal is the Dead Multiplier ladder, so this is a bonus-chasing game. If you want the studio's mechanics with a smaller ceiling, Outsourced caps at 5,000× on a 4×4 grid. If you want more headroom on the same xWays engine, San Quentin xWays runs to 150,000×.
