You're describing a color-matching puzzle game inspired by mechanics seen in games like Tetris combined with Bejeweled or Puyo Puyo, where the core objective is to eliminate colored viruses by matching four or more of the same color (red, yellow, blue) in a row—either horizontally or vertically.

Here’s a clear, structured summary of how the game works, optimized for understanding, design, or even implementation:

🎮 Game Title (Suggested): Virus Match: Clear the Bottle

🧫 Core Objective

Eliminate all colored viruses from the board by matching four or more segments of the same color (red, yellow, blue) horizontally or vertically.

• Win Condition: Clear all viruses on the board for the level.
• Lose Condition: Capsules stack up and block the narrow top opening of the bottle.

🔧 Gameplay Mechanics

1. Capsule System

• Capsules descend from the top of the board in random shapes (like Tetris pieces).
• Each capsule contains colored segments (one or more) in red, yellow, or blue.
• You can:
  • Move left/right to position the capsule.
  • Rotate the capsule (90° increments) to fit your strategy.

2. Matching & Clearing

• When four or more same-colored segments (from capsules or viruses) align in a row or column, they disappear.
• Viruses and capsule segments count toward matches.
• Matching creates chain reactions if new connections form after a clear (though chain reactions don’t give extra points).

3. Scoring System

• Base Points: Earned per virus cleared.
• Bonus Points:
  • More points for clearing multiple viruses at once (e.g., clearing 5 viruses in one move = higher bonus than 1).
  • No bonus for chain reactions, only for simultaneous clears.
• Speed Multiplier:
  • Slow Speed: Lower point value per virus.
  • Medium Speed: Standard multiplier.
  • Fast Speed: Higher point multiplier (e.g., ×1.5 or ×2).
• Total Score =
  (Viruses Cleared × Base Value) × Speed Multiplier × Bonus for Simultaneous Clears

⚙️ Game Progression & Difficulty

• Start with a difficulty level (0–20):

  • Higher level = more viruses to clear.
  • Example: Level 0 → 10 viruses; Level 20 → 50+ viruses.

• Speed Settings:

  • Slow / Normal / Fast
  • Affects how quickly capsules fall and how much you earn per match.

• After beating Level 20:

  • Game continues in Endless Mode.
  • Number of viruses to clear stays capped (e.g., 50), but you keep playing to maximize your score.
  • Goal: Top score leaderboard.

🎯 Key Game Features

• ✅ No time pressure – Focus on strategy, not speed.
• ✅ No penalty for number of capsules used – Efficiency is not measured.
• ✅ Chain reactions allowed, but only direct multi-virus clears grant bonuses.
• ✅ Tactical stacking: Plan placements to trigger large clears and maximize points.

📈 Strategy Tips

• Aim for 4+ viruses in a single match – maximizes bonus.
• Use the bottle’s narrow opening wisely – avoid blocking it early.
• Save long combos for higher difficulty levels – they’re essential for beating hard levels.
• Play on Fast mode for higher scores, but expect more pressure.

🏆 Final Notes

• The game blends Tetris-style placement with match-3 puzzle logic.
• It’s addictive, skill-based, and score-driven, perfect for mobile or casual platforms.
• Great for casual and competitive players alike — from relaxing to high-score chasing.

🎯 Example Scenario:

You’re on Level 15 (25 viruses to clear) at Fast speed.
You place a capsule so that 6 red viruses and 3 red capsule segments align.
✅ You clear 6 viruses in one move → big bonus.
✅ Speed multiplier = ×2 → score doubled.
🏆 You now have a high chance to beat the level and keep climbing.

Let me know if you’d like:

• A prototype design (UI wireframe, board layout),
• Scoring formula (math-based),
• Level progression curve (how virus count increases),
• Or even a script/algorithm for detecting matches.

Keep the board clean and the viruses gone — you’ve got this! 💉🧫🔥
