How it plays
Mental, released 31 August 2021, is set in a 1920s mental institution and plays on a 5-reel, 3-2-3-2-3 grid starting at 108 ways to win. Bets run from €0.20 to €70, and the published hit frequency is 34.19%.
Three signature mechanics drive the math: xWays symbols expand into multiple instances, xSplit blades split symbols in two, and xNudge wilds nudge to full view while raising their multiplier with every step.
Bonus features
Scatters award three escalating bonus rounds: Autopsy, Lobotomy and Mental Free Spins, layering sticky Fire Frames, Dead Patient multipliers (from x5 up to x9999) and symbol transformations.
Feature buy-ins are published at 80x to 1,000x the base bet in markets where buying is permitted.
RTP versions
The headline configuration returns 96.08%, with a reduced 94.20% version distributed to some casinos.
The 66,666x max win carries a published probability of roughly 1 in 18 million spins — one of the most volatile profiles Nolimit City has released.
