✅ Phase 1: Core Game Implementation - COMPLETE!

🎯 Objectives Achieved

✅ Frontend-Backend Integration

• API Service Layer: Complete axios-based API client with error handling
• State Management: Zustand store for game state, session data, and UI state
• Real-time Updates: Timer hooks and game flow management
• Error Handling: Comprehensive error handling with retry logic and user feedback

✅ Core Game Features

• Player Registration: Name validation and session creation
• Question Management: Random question fetching from backend
• Answer Submission: 3-attempt system with hint support
• Scoring System: 2 points (no hint) / 1 point (with hint) / 0 points (failed)
• Session Timer: 30-minute game sessions with warnings
• Leaderboard: Real-time top 10 players display

✅ User Interface

• Modern React UI: Material-UI components with responsive design
• Game Flow: Smooth transitions between lobby → game → results
• Visual Feedback: Loading states, progress bars, success/error alerts
• Interactive Elements: Hint system, skip functionality, timer display
