A fully functional, interactive chess game built with modern web technologies, featuring a beautiful UI, sound effects, and responsive design. This project demonstrates complete chess logic implementation with all standard rules, piece-specific movement validation, and an engaging user experience enhanced by professional audio integration and smooth animations.
Key Features
Complete Chess Implementation
- All standard chess pieces with proper movement rules
- Pawn special moves (initial double move, diagonal capture)
- Piece-specific validation (Knight L-shape, Bishop diagonal, etc.)
- Path collision detection for long-range pieces
- Win condition detection with king capture mechanics
Interactive Gameplay
- Click-to-select and move pieces with visual feedback
- Selected pieces highlighted with yellow indicator
- Possible move indicators with green highlighting
- Turn-based gameplay with automatic player switching
- Game state management with reset functionality
Audio Features
- Dynamic sound effects with synthesized tones for moves
- Capture sounds using membrane synthesis
- Game over sound sequence with FM synthesis
- Lazy audio loading initialized on first user interaction
- Graceful fallback when audio fails with error handling
Modern UI/UX Design
- Warm orange/amber color scheme with gradient backgrounds
- Hover effects with scaling and smooth transitions
- Retro-gaming aesthetic with modern touches
- Unicode chess symbols (♔♕♖♗♘♙) for visual appeal
- Responsive design with mobile-first approach
