Mental Slot Bonuses and Features

Get ready, as this is a slot with many bonus features! We’ll start with the Fire Frames feature, which sees 1-13 positions on the reels being framed with fire. Any symbol landing in a position with a fire frame gets split into two parts, increasing the number of ways to win.

Next are the Enhancer Cells, found at the bottom of the second and fourth reels. The one under reel two is activated when there are four fire frames, and the one under reel four is activated when there are six fire frames. The enhancer cell will then transform into a wild, patient, or dead patient. It could also become an xWays symbol revealing three symbols of the same kind, or an xSplit symbol, which splits one symbol on each reel before turning into two wilds. Finally, it could turn into an xNudge symbol, causing a wild to be nudged until it’s fully visible on a reel – the more nudges it takes, the higher the multiplier becomes.

Then there’s the Dead Patient feature, which activates when there are two dead patient symbols on the reels. The symbols will have random multipliers assigned to them – you could get a giant 9,999x multiplier thanks to this bonus feature!

Land the spider symbol on reel two or four, and you’ll start the Mental Transform feature. The Spider symbol then transforms into an xWays, xSplit, patient, dead patient, or wild symbol.

There are then three free spins bonuses, the first being Autopsy Free Spins. These are started by getting three scorpion symbols on the reels. You’ll get eight free spins plus an extra free spin for each scorpion in a fire frame. During this feature, up to five fire frames are added per spin, and these stay in place for the duration of the free spins. Land a spider symbol anywhere and you might be upgraded to Lobotomy Free Spins.

The next free spins bonus is Lobotomy Free Spins, which starts when you get three scorpion symbols and a spider symbol on the reels. You’ll get nine free spins plus an extra free spin for each triggering symbol in a fire frame. All spider symbols are sticky, triggering the Mental Transform feature on every spin, as are fire frames. Multipliers from dead symbols are collected and added to the respective patient symbols when they land, reducing the count by one. Land two spider symbols and the feature will upgrade to Mental Free Spins. 

Finally, we have Mental Free Spins. These start when you get three scorpions and two spiders on the same spin. You’ll get ten free spins plus an extra free spin for each triggering symbol in a fire frame. Both spider symbols are sticky, triggering the Mental Transform feature on every spin, as are fire frames. You can build a multiplier like in the Lobotomy Free Spins, but the count won’t ever go down.

Fed up with waiting for the free spins to start? If so, you can buy them by clicking the star button. Autopsy Free Spins cost 80x your bet, while Lobotomy Free Spins cost 230x your bet. Mental Free Spins are 1,000x your bet. You can also pay 232x your bet and have one of the three free spins features chosen randomly.
