Mental Slot Review

The Mental online slot is another slice of weirdness from the studios of Nolimit City. You can win insane prizes of up to 66,666x your bet from this asylum-set game. Splitting symbols, transformations, extra wilds, and several free spins rounds are among the disturbing features of this desktop and mobile slot machine.

Are you Brave Enough to Enter?

This is certainly not a game for those with a nervous disposition. Play the Mental slot online to encounter graphic images of lobotomies, dead patients, internal organs, and a guy in a Hannibal Lector-type mask. There’s a gritty, Victorian style to the patients and anatomical drawings.

Known for their unusual games, online slots and software provider, Nolimit City have gone all-out to shock players with this crazy game. If you like horror, you’re going to love the images used here.

Line up the Patients

You have 108 ways to line symbols across the 3-2-3-2-3 grid. The bet range is from 0.20 to 70.00, or you can play Mental for free before staking anything at the top casinos. Check out this paytable to see how many times the total bet you win from each symbol –

Match Three
Match Four
Match Five
Patient 5
Patient 4
Patient 3
Patient 2
Patient 1

The extremely high volatility could drive you nuts, but decent returns of 96.06%, and the potential for truly massive wins, provide the perfect cure.

Going Crazy for Extra Features

The Mental slot machine comes packed with features. Flames surround up to 13 symbols, and these split to create more winning ways. Dead Patient symbols come with random multipliers of 5x to a vast 9,999x, while Enhancer Cells at the bottom of the game reveal special symbols.

These include xWays reel expansion symbols and xSplit emblems which divide into wilds. You could also see regular wilds, or xNudge wilds, which move up or down to fill the reels, and increase a multiplier with each step.

A golden spider on the reels of the Mental slots game transforms into xWays, xSplit, xNudge, or Dead Patient symbols.

Three free spins bonus features trigger from various scatter symbols. Scorpions award the Autopsy spins, with sticky fire frames, while the Lobotomy spins feature a Dead Patient collection mechanism. Spider transformations and increasing Dead multipliers are found in the Mental free games.

More Blood-Curdling Games

Similar games include the post-apocalyptic Infectious 5 xWays slot, also from Nolimit City, and the asylum-set Book of Madness online slot from Bally Wulff.

A Mind-Bendng Slot

The complex features and grisly images won’t appeal to everyone. But play the Mental slot machine to discover insane gameplay and the potential to win 66,666x your bet. The numerous features could challenge even the sharpest minds, but if you are up for it, get your head around the Mental online slot at our favorite Nolimit City casinos.
