Mental
Mental RTP and Wagering
Mental is played on 5 reels, up to 20 rows, and 108 ways to win (though this can increase to more than 1,000). You can bet from €0.20 to €100 per spin.
You need to land at least three matching symbols across adjacent reels, starting from the first reel, to win a prize in Mental (as with most other slots).
Mental is highly volatile. While you may not win prizes as often as in a game with lower volatility, Mental offers bigger payouts more sporadically, especially through the Dead Patient and free spins features.
The Return to Player (RTP) rate in this slot game is just above the average at 96.08%. Combined with the high volatility, the decent RTP means there’s potential to win big prizes in Mental, right up to 66,666x your bet, though it may take a lot of spins to get there. Always bet responsibly.

Mental Symbols and Audio & Video Design
Mental’s theme, design, and atmosphere won’t be for everyone. If you prefer slots with colourful graphics, fun characters, and charming music, you may find Mental just too creepy. But it’s still a genuinely stunning achievement for Nolimit City.
The game is set in a spooky, gothic asylum, complete with flickering lights, broken tiles, and patients. The outstanding graphics have a distinctive sepia-toned style and incredibly detailed symbols. Mental’s music is also a powerful addition and subtly adds to the game’s strange feel.
Mental includes 14 symbols, including 5 patient symbols and 5 organ symbols. The Wild symbol, featuring a skull with a “W” on its forehead, substitutes for all symbols except the Scorpion, Spider, and Dead Patient.

Mental Mobile Features
Mental was created with HTML5 technology, so it looks just as striking on mobile devices as it does on desktop. You can switch between portrait and landscape modes to suit your preferred playing style. The controls adjust to the orientation and screen size to give you the most convenient layout.
Mental Bonus Features
Mental’s macabre range of features is outstanding, ranging from free spins to transforming symbols.
Fire Frames
Between 1 and 13 symbols on the reels randomly get framed by fire during the base game. Symbols in Fire Frames split into two pieces to help you create winning combinations.
Dead Patient
Land two Dead Patient symbols to trigger this feature. One Patient symbol is revealed with a random multiplier of between x5 and x9,999.
Enhancer Cells
Enhancer Cells sit at the bottom of reel 2 and reel 4. They only become activated if four or six Fire Frames appear on the reels.
Enhancer Cells can reveal any patient symbol, Dead Patient symbols, and more effects to help you win.
Mental Transform
If you land a Spider on reel 2 or 4, it transforms into an xWays, xSplit, Wild, Dead Patient, or patient symbol.
Autopsy Free Spins
Land three Scorpion symbols to win eight free spins. Any Scorpions in a Fire Frame award an extra free spin each. Fire Frames can appear on up to five symbols on each spin and then stay in place for the entire feature.
Lobotomy Free Spins
Three Scorpion symbols and one Spider symbol in the base game awards nine free spins. This feature uses sticky Spider symbols, Mental Transform on each spin, and a Dead Multiplier of up to x15 on Dead Patient symbols.
Mental Free Spins
Match 3 Scorpions and 2 Spiders during the base game to win 10 free spins. This includes the Dead Multiplier, which increases with each Dead Patient symbol revealed.
Mental Final Thoughts
Mental is a unique 5-reel slot with 108+ ways to win and up to 20 rows. It’s unlike any other slot we’ve seen, with a bold theme and an amazing but creepy design. The RTP is just above average at 96.08%, the volatility is high, and there’s a huge top win of 66,666x your bet on offer.
The range of features is spectacular, with three free spins rounds that include transforming symbols and increasing multipliers. If you’re looking for a slot that offers terrific potential wins, great features, and a fresh feel, Mental is a must. The dark theme and fairly grotesque visuals may put some players off, though, so try our demo first.
