Bonus Features Deep Dive
1. Contagious Wild Outbreak
- Trigger: A Wild Virus symbol lands on the reels.
- Mechanic: After any win it contributes to, the virus "spreads".
- Effect: It randomly infects 2-4 symbols adjacent to it, transforming them into additional wilds for the next spin.
- This can create a chain reaction of wilds across the grid.
2. Diagnosis Bonus (Pick-Me Game)
- Trigger: Land 3 or more Bonus (Mystery Pill) symbols on a payline.
- Mechanic: You are presented with 3 patient files (Easy, Medium, Hard).
Each file leads to a different game:
- Easy: Pick from 8 bandages to reveal instant cash prizes. Find the "Cured" symbol to win.
- Medium: A puzzle game where you connect nerves to the brain to reveal multipliers.
- Hard: A high-risk game where you must avoid "Terminal" symbols to uncover a major prize (e.g., 100x bet).
3. Experimental Surgery Free Spins
- Trigger: Land 3+ Scatter (X-Ray Screen) symbols on the reels.
Awards:
- 3 Scatters = 8 Free Spins
- 4 Scatters = 12 Free Spins
- 5 Scatters = 15 Free Spins
The Patient's Health Meter:
- A health bar is displayed for the patient.
- Every winning spin improves the patient's health by 25%.
- Every non-winning spin lowers health by 10%.
- The win multiplier is directly tied to the health level: 100% Health = 5x Multiplier, 50% Health = 2x Multiplier, etc.
- If health reaches 0%, the free spins end prematurely.
- The goal is to keep the patient stable for massive, multiplied wins.
