Go crazy for the Mental online slot at the top New Jersey online casinos or the best Pennsylvania online casinos. Set in an old asylum, it’s a desktop and mobile game that features disturbing images of lobotomies, dead patients, and body parts across 5 reels. It’s not a game for the squeamish, but has many of the ingenious gameplay features that we expect from the minds at Nolimit City.

Splitting symbols, nudging wilds, and a range of free spins rounds are among the mind-blowing extras that come with this high volatility game. There’s an average payback percentage of 96.08% and you can win an insane 66,666x your wager from the Mental slot.

Set within the stained tiled walls of the asylum, the grim symbols appear in a 3-2-3-2-3 pattern on your PC, Android, iOS, or Windows mobile. The symbols look like Victorian-era scientific drawings, and include eyes, brains, skeleton hands, and 5 patients in various unpleasant situations. One has a gag-ball in his mouth, one has electrodes wired to his brain, and patient number 4 looks to be dead. Flickering lights and a sinister soundtrack add to the sense of dread.

It’s pretty gruesome, but certainly distinctive. The easy to use controls are the same as those found across the Nolimit City range. Click the ‘$’ symbol on the panel to reveal a wager range of 0.20 to 70.00 for each spin. The arrow button starts an Autoplay feature, while the bolt of lightning on the controls will speed up the gameplay.

Take a look at the payable via a click on the 3 small dots symbol. This reveals a basic 108 different ways to line symbols across the reels for a win. The most valuable is a guy in a mask, and he’s worth 5x your wager when he lands across all 5 reels.

The Mental online slot comes packed full of extra features, and while they may seem a little overwhelming at first, once you start to play the game, they all make sense. Fire Frames can appear around anything from 1 to 13 symbol positions, and these split into 2 symbols, one above the other.

If 2 or more Dead Patient symbols land at once they reveal a multiplier from a range of 5x to a colossal 9,999x! Special Enhancer Cells sit below reels 2 and 4. Fire Frames above these will activate a Dead Patient feature, or any of the following –

• xWays – These reveal 3 matching symbols and expand the reel heights.
• xSplit – A symbol splits on each reel and then splits into 2 wilds.
• Regular Wild symbol – This yellowish skull acts as others to help complete wins.
• xNudge Wild – The wild nudges up or down until it’s fully in view. A multiplier increases by 1x for each step.

A golden spider on either reel 2 or 4 awards the Mental Transform feature. Spiders mutate into Xways, xSplit, Wild, or Dead Patient symbols.

Land 3 scorpions to claim 8 Autopsy free spins casino bonus rounds. Up to 5 Fire Frames appear in each bonus game, and they remain active for any remaining spins. Any 3 scorpions and a spider will trigger the Lobotomy free spins, where spiders are sticky and award the Mental Transform throughout. A Dead Patient collection feature helps you to build huge multipliers during the Lobotomy games, and they only reset when regular patients appear.

If 3 scorpions and 2 spiders appear, you enter the Mental free spins games. Dead Patient multipliers continue to increase throughout this feature. Autopsy and Lobotomy spins can upgrade when spiders appear, and any free games feature ends if you are lucky enough to win 66,666x your wager during the course of the bonus spins.

Play with the maximum stake of 70.00 per spin and it’s possible to collect a win of 4,666,620.00 from the Mental online slot. That’s a vast prize, but the odds against actually reaching it are equally huge. This is a high volatility slot, with a long-term payback percentage of 96.08%.

Fans of movies such as Saw, will certainly appreciate the style, but as mentioned earlier, it won’t appeal to everyone. It’s also not a game for inexperienced slots players, as the multiple features will throw you in at the deep end.

But it’s a thrilling game with lots going on, and the potential for some of the biggest payouts from any slot machine we’ve seen. Why not go mad and play the Mental online slot at our recommended Pennsylvania slots sites and the top New Jersey slots sites today?
