How Mental works

The game starts on a 5 × 3 layout, but the Nolimit City mechanics can expand it during a spin.

Two dead patient symbols can give a random multiplier from x5 to x9999 on the patient symbol. Enhancer Cells switch on with 4 or 6 fire frames and add xWays, xNudge or xSplit. The spider triggers Mental Transform, which changes symbols.

Three types of free spins

Scorpions and spiders decide which bonus you get.

3 scorpions give Autopsy Freespins with sticky fire frames.
3 scorpions and a spider give Lobotomy Freespins with a sticky spider and symbol transformation on every spin.
3 scorpions and 2 spiders give Mental Freespins, where the dead patient multiplier never goes down.

The bonus buy costs from 80x to 1,000x the bet. Some regulated markets do not offer this option.

Mental stats

Nolimit City describes the volatility as extreme. According to the provider, a win lands on 34.19% of spins, free spins come once in 216 and the max win once in 18 million. This is a game for experienced players and small bets.

Fire Frames can turn a normal spin into a really good one. Usually though the balance just slowly drops.

What are the odds of getting free spins?

Reply from the editors

Nolimit City states that free spins trigger on average once every 216 spins. That is a statistical value, and in a single session it can take much longer.
