Mental Symbols Paytable
Mental by Nolimit City features a macabre and immersive design, reflected in its symbol set. The game divides its symbols into two main categories, each contributing uniquely to the gameplay and payout potential.
Organ Symbols - Low Paying Symbols

The low-paying symbols depict various organs, including the eyes, brain, heart, kidneys, and hand. These symbols offer payouts ranging from 0.1x to 1.25x your base bet. While these smaller payouts might not seem significant, they help sustain your bankroll, allowing you to chase the slot's thrilling features and bigger wins. Their consistent appearances ensure the game maintains a dynamic flow, with frequent small wins to keep the excitement alive.
Patient Symbols - High Paying Symbols

The high-paying symbols are represented by five haunting Patient portraits, numbered 1 to 5, each with its eerie and unsettling design. These symbols offer payouts ranging from 0.4x to 5x your base bet. Beyond their standard payouts, these symbols often come into play during bonus rounds and special features, amplifying their potential to deliver massive wins. Combined with the game's unique mechanics and free spins bonuses, Patient symbols are your ticket to the slot's life-altering jackpot potential.
Key Features of Mental Explained
The Mental slot game from Nolimit City elevates the excitement with its mind-bending bonus rounds. These features are where the true madness unfolds, offering players thrilling opportunities for massive wins. Let’s explore the main highlights:
Enhancers Cells
Positioned at the bottom of reels 2 and 4, Enhancer Cells activate with 4 or 6 Fire Frames, respectively. Each cell can reveal one of the five patient symbols or the regular Dead Patient symbol, boosting your chances of unlocking big wins.
Dead Patient
Landing two Dead Patient symbols on the reels reveals a random patient symbol with a multiplier ranging from x5 to x9999 of your base bet. This feature can generate significant payouts, especially when combined with other mechanics.
Mental Transform

When a Spider symbol lands in the base game, it triggers the Mental Transform feature, converting into one of the following:
- Dead Patient Wild
- Patient Symbols
- Special Enhancer Symbols:
- xWays®: Reveals 3 identical symbols (excluding Scorpion, Spider, and Dead Patient), expanding the reel height. Multiple xWays symbols reveal the same symbol.
- xSplit®: Splits one symbol per reel, doubling them and amplifying their impact.
- xNudge®: Nudges up or down to fully display the symbol, increasing its multiplier by 1 per nudge.
Fire Frames - Symbol Splits

At the start of every spin, 1-13 random positions on the reels are marked as Fire Frames. Symbols landing in these frames split into two, effectively doubling the symbol and enhancing the chances for bigger combinations.
If a high-value patient symbol lands in a Fire Frame, the payout potential skyrockets. This unpredictable feature keeps each spin engaging and dynamic.
Autopsy Free Spins

Triggered by landing three Scorpion symbols on reels 1, 3, and 5, this bonus round awards 8 free spins, plus additional spins for Scorpion symbols landing in Fire Frames during the triggering spin.
During this round:
- Up to five Fire Frames appear per spin and remain sticky for the bonus duration.
- Fire Frames increase the likelihood of symbol splits, creating more winning combinations.
- Landing a Spider symbol upgrades the feature to Lobotomy Free Spins, adding another layer of excitement.
Lobotomy Free Spins

To activate this feature, land three Scorpion symbols and one Spider symbol in the base game, or trigger it during Autopsy Free Spins by landing a Spider symbol. Lobotomy Free Spins begin with 9 free spins, and additional spins can be earned through Fire Frames.
Features include:
- Sticky Spider Symbols: Trigger the Mental Transform feature on every spin.
- Dead Multiplier: Collects multipliers from Dead Symbols and applies them to specific patient symbols when they appear, amplifying payouts.
- Like the Autopsy round, Lobotomy Free Spins can upgrade to Mental Free Spins by landing an extra Spider symbol.
Mental Free Spins

The ultimate bonus round, Mental Free Spins, is triggered by:
- Three Scorpion symbols and two Spider symbols in the base game.
- Two Spider symbols in Autopsy Free Spins.
- One Spider symbol in Lobotomy Free Spins.
Players start with 10 free spins, with additional spins awarded for Scorpion or Spider symbols landing in Fire Frames during the triggering spin.
Key highlights:
- Up to five sticky Fire Frames appear on each spin, boosting the chances for big wins.
- Both Spider symbols become sticky, triggering Mental Transform on every spin.
- Dead Multipliers persist throughout the round, continuously growing as they transfer to patient symbols.
This feature offers the highest payout potential, making it the best opportunity to hit the game's maximum payout of 66,666x the base bet.
Bonus Buy
For those high stakes gamblers who want to jump straight into the action, Mental has a buy-in feature to lock a guaranteed bonus drop:
- Autopsy Free Spins: For x80 times your base bet, 8-11 Free Spins.
