A modern, feature-rich Tetris implementation built with Python and Pygame. This version includes official Tetris standards, advanced visual effects, sound system, and comprehensive gameplay mechanics.

• Official Tetris Standards: Proper piece colors, 7-bag randomization system, and standard scoring.
• Modern Controls: Ghost piece preview, hard drop, hold piece functionality, and smooth rotation.
• Progressive Difficulty: Dynamic level progression with increasing speed every 10 lines cleared.
• Combo System: Bonus points for consecutive line clears.
• Performance Tracking: Real-time PPS (Pieces Per Second) and LPS (Lines Per Second) metrics.

• Enhanced Graphics: Gradient blocks with 3D appearance, particle effects, and screen shake.
• Visual Feedback: Line clear animations, flash effects, and animated glow around current piece.
• Sound System: Procedural audio generation with movement sounds, line clear effects, and special Tetris sound.
• Professional UI: Comprehensive side panel with statistics, hold piece preview, and next piece queue.

• Multiple Game States: Main menu, pause functionality, and proper game over handling.
• Statistics Tracking: Detailed piece usage statistics and performance metrics.
• High Score System: Persistent top 10 score tracking saved to JSON file.
• Next Piece Preview: Shows upcoming '3' pieces instead of just '1'.

# Install required dependencies
pip install pygame numpy

# Clone or download the repository
# Run the game
python TetriX.py

• Python 3.6+
• Pygame library
• NumPy (for sound generation - optional)

• Single Line: 100 ×ばつ level
• Double Lines: 300 ×ばつ level
• Triple Lines: 500 ×ばつ level
• Tetris (4 Lines): 800 ×ばつ level
• Combo Bonus: 50 ×ばつ combo ×ばつ level
• Hard Drop Bonus: 2 points per cell dropped

• Levels increase every 10 lines cleared.
• Drop speed increases with each level.
• Maximum challenge at higher levels with near-instant piece falling.

Uses the modern Tetris piece generation system ensuring fair distribution:

• Each "bag" contains one of each piece type (I, O, T, S, Z, J, L).
• Pieces are shuffled randomly within each bag.
• Prevents long droughts of specific pieces.

• TetrisGame: Main game controller handling states, events, and rendering.
• Tetrimino: Individual piece management with rotation and collision detection.
• SoundManager: Procedural audio generation and sound effect management.
• Particle: Visual effects system for enhanced gameplay feedback.

• Menu: Professional start screen with control instructions.
• Playing: Active gameplay with full feature set.
• Paused: Game suspension with overlay.
• Game Over: Final statistics and restart options.

• 60 FPS: Smooth gameplay with consistent frame rate.
• Efficient Rendering: Optimized drawing routines for complex visual effects.
• Memory Management: Proper cleanup of particles and effects.
• Responsive Input: Immediate control response without lag.

• Line Clear Effects: Explosion particles when lines are cleared.
• Piece Lock Effects: Small particle burst when pieces lock in place.
• Dynamic Colors: Randomized particle colors for visual variety.

• Screen Shake: Dramatic effect for Tetris (4-line) clears.
• Flash Effects: Screen flashing for major events.
• Glow Animation: Animated glow around the current falling piece.
• Line Clear Animation: Smooth animated clearing of completed lines.

• Gradient Blocks: 3D appearance with lighting effects.
• Enhanced Borders: Multiple border layers for depth.
• Ghost Piece: Semi-transparent preview showing drop position.
• Color Coding: Official Tetris color scheme for each piece type.

• PPS (Pieces Per Second): Measure of play speed.
• LPS (Lines Per Second): Efficiency metric.
• Game Time: Total elapsed time.
• Piece Distribution: Count of each piece type used.

• High Scores: Top 10 scores saved to tetris_scores.json.
• Automatic Saving: Scores saved automatically on game over.
• Error Handling: Graceful handling of file system issues.

The game automatically detects sound capabilities:

• Falls back gracefully if NumPy is not installed.
• Continues without sound if audio system fails.
• Procedural generation creates sounds dynamically.

• 60 FPS target with automatic frame rate management.
• Particle count automatically managed for performance.
• Visual effects can be reduced on slower systems.

1. No Sound: Install NumPy (pip install numpy) or ignore - game works without sound.
2. Slow Performance: Reduce particle effects by modifying particle count in code.
3. Installation Issues: Ensure Python 3.6+ and Pygame are properly installed.

• Minimum: Python 3.6, Pygame.
• Recommended: Python 3.8+, NumPy.

• T-Spins: Use the hold piece strategically for complex clears.
• Combo Building: Chain multiple line clears for maximum scoring.
• Speed Management: Use soft drop to maintain control at higher levels.
• Ghost Piece: Plan moves using the ghost piece preview.

• Monitor piece statistics to anticipate piece droughts.
• Use the next piece preview to plan 2-3 moves ahead.
• Hold piece is crucial for avoiding difficult situations.
• Focus on Tetris clears (4 lines) for maximum points.

• Official Tetris color scheme and piece generation.
• Hold piece system with 'C' key functionality.
• Ghost piece showing drop preview.
• Advanced visual effects with particles and animations.
• Sound system with procedural audio generation.
• Performance metrics and comprehensive statistics.
• High score persistence system.
• Enhanced UI with multiple game states.

• Object-oriented design with proper separation of concerns.
• Robust error handling for file operations and sound system.
• Optimized rendering pipeline for complex visual effects.
• Memory-efficient particle system with automatic cleanup.

This is a complete, standalone Tetris implementation. The code is well-structured and documented for educational purposes and further enhancement.
