It’s not often that an online slot game completely subverts expectations. This is exactly what Mental succeeds at, though, as it brings a completely fresh and unique experience to the table. 

Based in a super creepy asylum (where all the nurses and doctors appear to have gone missing), you’re faced with the terrifying task of having to spin the reels and get as many winning combinations as possible without bolting out the door. If you can do this, there’s a good chance that you’ll be handsomely rewarded for it. 

What does mental offer in terms of features? Quite a lot, actually. Grab your notepad and let’s examine them: 

  • NoLimit BONUS

The maximum payout of Mental is 66.666 your base bet. If you manage to collect winnings that surpass this, the game will end and 66.666 x the base bet will be awarded. 

To cap everything off, Mental also has one of the creepiest soundtracks you’ll ever hear in a slot game. When you combine this together with the scary (and uber realistic) symbols, you’ll understand why Mental has sent shockwaves through the slot machine community. 


In the base game, 1 to 13 symbol positions on the reels get a FIRE FRAME. From there, any symbol that subsequently lands on a FIRE FRAME will split into 2 parts. 


Who doesn’t love some MULTIPLIERS? Whenever you land 2 or more DEAD PATIENT symbols, this will activate a random MULTIPLIER. 


You can find the ENHANCER CELLS at the bottom reel number 1 and reel number 2. These cells get activated whenever 4 or 6 FIRE FRAMES appear on the reels. Once this happens, you can get WILDS and lots of other boosters. 


In Mental, there’s a creepy SPIDER symbol. If you land it on reel 1 or reel 4, it’ll transform into a WILD, PATIENT, or DEAD PATIENT symbol. It’s also possible for it to become an xWays or xSplit symbol.


Land 3 SCORPIAN symbols and get yourself some FREE SPINS. 

NoLimit Bonus

Mental allows you to purchase bonuses yourself. This way, you can fast-track into one of the BONUS FEATURES that you really like.
