Mental Slot Bonus Games
The bonus games in Mental are where the real action begins. These features take the eerie asylum theme to the next level, offering everything from sticky symbols to colossal multipliers that redefine what it means to win big. Each bonus round has its own twist—some focus on escalating multipliers, while others pile on free spins or unique mechanics like the Dead Patient feature. Don’t worry; we’ll break each one down in detail to ensure you know exactly how to maximize your chances.
Autopsy Free Spins
This mode activates when you land 3 Scorpion symbols on reels 1, 3, and 5. The minimum bet to trigger this feature varies, but keep in mind that betting higher increases the chances of hitting free spins. Once active, you’ll receive 8 free spins, and every Scorpion that lands in a Fire Frame adds an extra spin. What makes this feature unique is that 5 Fire Frames are added at the start of each spin, sticking for the entire bonus round. While the mechanics are straightforward, the sticky Fire Frames often result in huge payouts as symbols split and paylines multiply.
Advantages: Sticky frames create more win opportunities.
Drawbacks: High activation volatility.
Comparison: Similar to Dead or Alive 2’s free spins with sticky wilds but offers multipliers like San Quentin’s Lockdown Spins, providing a hybrid experience.
🔥 Strategy: Autopsy Free Spins
Stick with moderate bets to balance volatility and maximize re-trigger chances. Watch for Scorpions landing in Fire Frames—they are critical for bonus spins. Re-triggering this bonus depends on hitting the frames early, so avoid low bets that limit payout potential.
Lobotomy Free Spins
Landing 3 Scorpion symbols plus 1 Spider symbol takes you into this level, granting 9 free spins. This mode includes sticky Fire Frames and introduces a sticky Spider symbol that activates Mental Transform on each spin. Spider symbols also transfer collected multipliers to the corresponding patient symbols, significantly amplifying your win potential. Multipliers collected through Dead Patient symbols stay active for the duration of this mode.
Advantages: Guaranteed multiplier collection; Spider symbol adds extra layers of excitement.
Drawbacks: Rarer trigger than Autopsy mode.
Comparison: Unlike Mental’s Autopsy Free Spins, this round mirrors Jammin’ Jars’ sticky multipliers but adds an extra dimension with guaranteed mental transformations.
🕸️ Strategy: Lobotomy Free Spins
Use this bonus to target Dead Patient multipliers, ensuring they are high before this feature activates. Bet slightly higher for greater multipliers and aim for Scorpions landing in Fire Frames to optimize sticky payouts.
Mental Free Spins
The top-tier bonus requires 3 Scorpion symbols and 2 Spider symbols to activate. Players receive 10 free spins, and sticky Spider symbols transform each spin into a high-stakes gamble. Fire Frames stick here too, amplifying the effect of Dead Patient multipliers. Unlike other bonuses, this mode keeps all collected multipliers active across the spins, making it the most rewarding feature.
Advantages: Uncapped multiplier potential; re-triggers can double your payout.
Drawbacks: Extremely high activation volatility.
Comparison: While it offers similar complexity to Nolimit City’s San Quentin, Mental Free Spins trumps it by allowing multiplier persistence throughout.
💀 Strategy: Mental Free Spins
Bet high but within reason—this is a high-risk, high-reward mode. Target Dead Patient symbols in Fire Frames before triggering this feature. Multipliers in this mode can snowball quickly, so keep your bankroll steady to play until you hit it.
