+
+## Advanced Build Script
+
+The advanced build script (`scripts/build.ts`) supports various options:
+
+```bash
+# Basic advanced build
+npm run build:advanced
+
+# Production build with migrations and tests
+npm run build:advanced:prod
+
+# CI/CD build (skips linting, includes tests and migrations)
+npm run build:advanced:ci
+```
+
+### Build Options
+
+- `--migrations`: Run database migrations during build
+- `--test`: Run tests during build
+- `--skip-lint`: Skip linting step
+- `--production`: Enable production mode (strict validation)
+
+## Deployment Scripts
+
+### Linux/Mac Deployment
+
+```bash
+./scripts/deploy.sh [deploy|build-only|test-connections]
+```
+
+Options:
+- `deploy` (default): Full deployment with validation
+- `build-only`: Build without connection testing
+- `test-connections`: Test database and Redis connections only
+
+### Windows Deployment
+
+```cmd
+scripts\deploy.bat [deploy|build-only|test-connections]
+```
+
+Same options as Linux/Mac version.
+
+### Required Environment Variables
+
+The deployment scripts require these environment variables:
+
+```bash
+DB_HOST=localhost
+DB_PORT=5432
+DB_USERNAME=postgres
+DB_PASSWORD=your_password
+DB_NAME=serpentrace
+JWT_SECRET=your_jwt_secret
+REDIS_HOST=localhost
+REDIS_PORT=6379
+```
+
+## Build Process Flow
+
+### Standard Build (`npm run build`)
+
+1. **Clean** - Remove previous build artifacts
+2. **Lint** - Code quality checks (if configured)
+3. **Compile** - TypeScript compilation
+4. **Copy Assets** - Copy non-TS files to dist
+5. **Post-build** - Validation and cleanup
+
+### Production Build (`npm run build:production`)
+
+1. **Clean** - Remove previous build artifacts
+2. **Lint** - Code quality checks
+3. **Test** - Run test suite
+4. **Migrations** - Apply database migrations
+5. **Compile** - TypeScript compilation
+6. **Copy Assets** - Copy non-TS files to dist
+7. **Validate** - Ensure build integrity
+
+### Advanced Build (`npm run build:advanced`)
+
+Provides fine-grained control over the build process with comprehensive logging and error handling.
+
+## Asset Management
+
+The build system automatically copies these file types to the dist directory:
+
+- `.json` files (configuration, data)
+- `.html` files (templates)
+- `.css` files (stylesheets)
+- Image files (`.png`, `.jpg`, `.jpeg`, `.gif`, `.svg`, `.ico`)
+- Font files (`.woff`, `.woff2`, `.ttf`, `.eot`)
+
+Excluded directories:
+- `node_modules`
+- `.git`
+- `tests`
+- `__tests__`
+
+## TypeScript Configuration
+
+The build system uses the following TypeScript settings:
+
+- **Target**: ES2020
+- **Module**: CommonJS
+- **Output Directory**: `./dist`
+- **Source Maps**: Enabled
+- **Declarations**: Enabled for type definitions
+- **Strict Mode**: Enabled for type safety
+
+## Migration Management
+
+### Creating Migrations
+
+```bash
+# Create empty migration
+npm run migration:create AddNewTable
+
+# Generate migration from entity changes
+npm run migration:generate AddNewTable
+
+# Full migration workflow (create + generate + run)
+npm run migration:full AddNewTable
+```
+
+### Migration Best Practices
+
+1. Always backup database before running migrations in production
+2. Test migrations in development environment first
+3. Use descriptive migration names
+4. Review generated migrations before running them
+
+## Docker Integration
+
+The build system is optimized for Docker deployments:
+
+```dockerfile
+# Use build:docker for container builds
+RUN npm run build:docker
+
+# Or use production build for full validation
+RUN npm run build:production
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Build fails with "Cannot find module"**
+   - Run `npm ci` to ensure all dependencies are installed
+   - Check TypeScript paths configuration
+
+2. **Migration errors during build**
+   - Verify database connection parameters
+   - Ensure database exists and is accessible
+   - Check migration files for syntax errors
+
+3. **Asset copying fails**
+   - Verify file permissions
+   - Check disk space availability
+   - Ensure source files exist
+
+4. **TypeScript compilation errors**
+   - Run `npm run typecheck` for detailed error messages
+   - Check tsconfig.json configuration
+   - Verify all type definitions are installed
+
+### Debug Mode
+
+Enable verbose logging by setting the environment variable:
+
+```bash
+export DEBUG=serpentrace:*
+npm run build:advanced
+```
+
+## Performance Optimization
+
+### Build Performance Tips
+
+1. Use `npm ci` instead of `npm install` in CI/CD
+2. Enable TypeScript incremental compilation for development
+3. Use `--skip-lint` in CI if linting is handled separately
+4. Cache node_modules in CI/CD pipelines
+
+### Runtime Performance
+
+The build system optimizes the output for production:
+
+- Source maps for debugging (can be disabled in production)
+- Type declarations for library usage
+- Compressed and optimized JavaScript output
+
+## Monitoring and Logging
+
+Build logs include:
+- Timestamps for each build step
+- Error details with stack traces
+- Performance metrics (build duration)
+- Validation results
+
+Production builds create detailed logs in the `logs/` directory.
+
+## Contributing
+
+When modifying the build system:
+
+1. Test changes with both development and production builds
+2. Update this documentation for any new scripts or options
+3. Ensure backward compatibility
+4. Add appropriate error handling and logging
+
+## Support
+
+For build system issues:
+1. Check this documentation
+2. Review error logs in the console
+3. Verify environment variables are set correctly
+4. Test with a clean `node_modules` installation

+# Docker Watcher Implementation Guide
+
+## Overview
+
+This document explains the Docker watcher implementation for the SerpentRace project, which automatically synchronizes local file changes with Docker containers and rebuilds images when necessary.
+
+## What's Implemented
+
+### Docker Compose Watch Configuration
+
+The development Docker Compose configuration now includes `develop.watch` sections for both frontend and backend services that provide:
+
+1. **File Synchronization**: Automatically sync source code changes to running containers
+2. **Selective Rebuilding**: Rebuild containers when critical configuration files change
+3. **Intelligent Ignore Patterns**: Exclude unnecessary files like `node_modules`
+
+### Backend Watcher Configuration
+
+```yaml
+develop:
+  watch:
+    - action: sync
+      path: ../SerpentRace_Backend/src
+      target: /app/src
+      ignore:
+        - node_modules/
+    - action: sync
+      path: ../SerpentRace_Backend/package.json
+      target: /app/package.json
+    - action: rebuild
+      path: ../SerpentRace_Backend/package-lock.json
+    - action: rebuild
+      path: ../SerpentRace_Docker/Dockerfile_backend.dev
+```
+
+### Frontend Watcher Configuration
+
+```yaml
+develop:
+  watch:
+    - action: sync
+      path: ../SerpentRace_Frontend/src
+      target: /app/src
+      ignore:
+        - node_modules/
+    - action: sync
+      path: ../SerpentRace_Frontend/public
+      target: /app/public
+    - action: sync
+      path: ../SerpentRace_Frontend/package.json
+      target: /app/package.json
+    - action: rebuild
+      path: ../SerpentRace_Frontend/package-lock.json
+    - action: rebuild
+      path: ../SerpentRace_Frontend/vite.config.js
+    - action: rebuild
+      path: ../SerpentRace_Docker/Dockerfile_frontend.dev
+```
+
+## How It Works
+
+### Sync Actions
+- **Purpose**: Instantly copy changed files from host to container
+- **Use Cases**: Source code files, static assets, configuration files that don't require rebuild
+- **Performance**: Near-instant updates, no container restart needed
+
+### Rebuild Actions
+- **Purpose**: Trigger full container rebuild when critical files change
+- **Use Cases**: Package files, Docker configuration, build configuration
+- **Performance**: Takes longer but ensures consistency
+
+## Usage
+
+### New Commands Added
+
+#### Windows (docker-manage.bat)
+```bash
+# Start with file watchers
+.\docker-manage.bat dev:watch
+
+# Traditional start (without watchers)
+.\docker-manage.bat dev:start
+```
+
+#### Linux/Mac (docker-manage.sh)
+```bash
+# Start with file watchers
+./docker-manage.sh dev:watch
+
+# Traditional start (without watchers)
+./docker-manage.sh dev:start
+```
+
+### Command Differences
+
+| Command | Mode | File Watching | Container Rebuild | Use Case |
+|---------|------|---------------|-------------------|----------|
+| `dev:start` | Background (-d) | No | Manual only | Traditional development |
+| `dev:watch` | Foreground | Yes | Automatic | Modern development with live sync |
+
+## Benefits
+
+### 1. Instant File Synchronization
+- Source code changes are immediately available in containers
+- No manual rebuild or restart required for code changes
+- Maintains all existing hot-reload functionality (nodemon, Vite HMR)
+
+### 2. Smart Rebuilding
+- Automatically rebuilds when package.json or Dockerfile changes
+- Ensures containers stay consistent with dependency updates
+- Prevents common issues with stale dependencies
+
+### 3. Development Efficiency
+- Combines Docker's isolation with native-like development speed
+- Reduces context switching between local and containerized development
+- Maintains consistent environment across team members
+
+## File Patterns Watched
+
+### Backend
+- **Synced Files**: 
+  - `src/` directory (all TypeScript source files)
+  - `package.json` (for runtime reference)
+- **Rebuild Triggers**: 
+  - `package-lock.json` (dependency changes)
+  - `Dockerfile_backend.dev` (container configuration)
+
+### Frontend
+- **Synced Files**:
+  - `src/` directory (React components, styles, etc.)
+  - `public/` directory (static assets)
+  - `package.json` (for runtime reference)
+- **Rebuild Triggers**:
+  - `package-lock.json` (dependency changes)
+  - `vite.config.js` (build configuration)
+  - `Dockerfile_frontend.dev` (container configuration)
+
+## Performance Considerations
+
+### Sync Performance
+- File synchronization is near-instantaneous
+- Uses Docker's built-in file watching mechanisms
+- Optimized for development workloads
+
+### Rebuild Performance
+- Rebuilds only occur when necessary
+- Docker layer caching reduces rebuild times
+- Can be resource-intensive for large dependency changes
+
+## Troubleshooting
+
+### Common Issues
+
+1. **File Changes Not Reflected**
+   - Ensure you're using `dev:watch` command
+   - Check that files are not in ignore patterns
+   - Verify file paths are correct
+
+2. **Excessive Rebuilds**
+   - Check for unnecessary changes to rebuild trigger files
+   - Consider moving files to sync-only patterns if appropriate
+
+3. **Performance Issues**
+   - Monitor Docker resource usage
+   - Consider excluding large directories from watching
+   - Use `.dockerignore` for files that should never be synced
+
+### Debugging Commands
+
+```bash
+# Check container status
+docker-compose -f SerpentRace_Docker/docker-compose.dev.yml ps
+
+# View watcher logs
+docker-compose -f SerpentRace_Docker/docker-compose.dev.yml logs -f backend
+docker-compose -f SerpentRace_Docker/docker-compose.dev.yml logs -f frontend
+
+# Check file synchronization
+docker exec -it serpentrace-backend-dev ls -la /app/src
+docker exec -it serpentrace-frontend-dev ls -la /app/src
+```
+
+## Requirements
+
+### Docker Compose Version
+- Requires Docker Compose v2.22+ for `develop.watch` support
+- Check version: `docker-compose version`
+
+### File System
+- Works on Windows, Linux, and macOS
+- Performance may vary based on file system type
+- WSL2 recommended for Windows users
+
+## Migration from Traditional Setup
+
+### No Breaking Changes
+- Existing `dev:start` command continues to work
+- All volume mounts remain functional
+- Hot reload functionality preserved
+
+### Gradual Adoption
+1. Try `dev:watch` for active development
+2. Use `dev:start` for background services
+3. Gradually migrate team to new workflow
+
+## Best Practices
+
+### Development Workflow
+1. Use `dev:watch` during active development
+2. Make code changes normally
+3. Watch for automatic synchronization
+4. Monitor logs for any sync issues
+
+### File Organization
+- Keep frequently changed files in sync patterns
+- Place build configuration in rebuild patterns
+- Use `.dockerignore` for files that should never sync
+
+### Team Collaboration
+- Document which command team members should use
+- Ensure consistent Docker Compose version across team
+- Share troubleshooting steps for common issues
+
+## Future Enhancements
+
+### Potential Improvements
+1. **Selective Service Watching**: Watch only specific services
+2. **Custom Ignore Patterns**: Per-developer ignore configurations
+3. **Performance Monitoring**: Built-in sync performance metrics
+4. **Integration with IDEs**: Better editor integration for sync status
+
+### Configuration Expansion
+- Additional file patterns as needed
+- Service-specific watch configurations
+- Environment-based watch rules

+
+## Navigáció és Routing
+
+### ✅ Helyes gyakorlat: HandleNavigate használata
+
+**MINDIG használd a központosított HandleNavigate hook-ot navigációhoz:**
+
+```jsx
+import HandleNavigate from "../../utils/HandleNavigate/HandleNavigate"
+
+const MyComponent = () => {
+  const { goHome, goLogin, goDeckDetails } = HandleNavigate()
+  
+  const handleClick = () => {
+    goHome() // Egyszerű navigáció
+  }
+  
+  const handleDeckView = (deckId) => {
+    goDeckDetails(deckId) // Dinamikus route paraméterrel
+  }
+  
+  const handleLobby = (gameCode) => {
+    goLobby({ gameCode }) // State passzolással
+  }
+}
+```
+
+### ❌ Kerülendő: Direkt useNavigate használat
+
+```jsx
+// SOHA NE HASZNÁLD EZT!
+import { useNavigate } from "react-router-dom"
+
+const MyComponent = () => {
+  const navigate = useNavigate()
+  navigate("/home") // ❌ NEM JÓ!
+}
+```
+
+### Elérhető Navigációs Függvények
+
+**HandleNavigate által biztosított függvények:**
+
+```jsx
+const {
+  // Általános
+  goTo,                    // goTo('/any-path', { state: {...} })
+  goBack,                  // Vissza az előző oldalra
+  
+  // Authentikáció
+  goHome,                  // → /home
+  goLogin,                 // → /login, state: { success, message }
+  goRegister,              // → /register (alias: goAuth)
+  goLanding,               // → / (landing page)
+  
+  // Deck Management
+  goDecks,                 // → /decks
+  goDeckDetails,           // goDeckDetails(deckId) → /deck/:deckId
+  goDeckCreator,           // → /deck-creator
+  goDeckCreatorEdit,       // goDeckCreatorEdit(deckId) → /deck-creator/:deckId
+  
+  // Game Flow
+  goLobby,                 // goLobby({ gameCode }) → /lobby
+  goChooseDeck,            // goChooseDeck({ username, deckIds }) → /choosedeck
+  goPlayerSetup,           // goPlayerSetup({ deckIds }) → /player-setup
+  goGame,                  // goGame({ players, gameState }) → /game
+  
+  // Egyéb
+  goContacts               // → /contacts (alias: goCompanies)
+} = HandleNavigate()
+```
+
+### Route Konstansok
+
+**Használd a centralizált route konstansokat:**
+
+```jsx
+// src/utils/routes.js
+import { ROUTES } from '../../utils/routes'
+
+// App.jsx-ben
+<Route path={ROUTES.HOME} element={<Home />} />
+<Route path={ROUTES.DECK_DETAILS} element={<DeckDetails />} />
+
+// ❌ NE használj string literálokat:
+<Route path="/home" element={<Home />} /> // NEM JÓ!
+```
+
+### State Passzolás
+
+**Így adj át adatokat navigáció során:**
+
+```jsx
+// Régi mód (useNavigate) - ❌ NE!
+navigate('/lobby', { state: { gameCode: 'ABC123' } })
+
+// Új mód (HandleNavigate) - ✅ JÓ!
+goLobby({ gameCode: 'ABC123' })
+
+// Fogadó oldalon:
+import { useLocation } from 'react-router-dom'
+
+const Lobby = () => {
+  const location = useLocation()
+  const gameCode = location.state?.gameCode
+}
+```

+
+## Komponens Konvenciók
+
+### Funkcionális Komponens Sablon
+
+```jsx
+import React, { useState, useEffect } from 'react'
+import HandleNavigate from '../../utils/HandleNavigate/HandleNavigate'
+
+/**
+ * Komponens rövid leírása
+ * @returns {JSX.Element}
+ */
+const MyComponent = () => {
+  // 1. Hooks (HandleNavigate, useState, useEffect, stb.)
+  const { goHome } = HandleNavigate()
+  const [data, setData] = useState(null)
+  
+  // 2. Effect hooks
+  useEffect(() => {
+    // Component mount logic
+  }, [])
+  
+  // 3. Event handlers
+  const handleClick = () => {
+    // Logic
+  }
+  
+  // 4. Render
+  return (
+    <div>
+      {/* JSX */}
+    </div>
+  )
+}
+
+export default MyComponent
+```
+
+### Import Sorrend
+
+```jsx
+// 1. React és third-party library-k
+import React, { useState } from 'react'
+import { motion } from 'framer-motion'
+
+// 2. React Router hooks (useLocation, useParams - NEM useNavigate!)
+import { useLocation } from 'react-router-dom'
+
+// 3. Custom hooks és utils
+import HandleNavigate from '../../utils/HandleNavigate/HandleNavigate'
+import useRequireAuth from '../../hooks/useRequireAuth'
+
+// 4. API
+import { getUserData } from '../../api/userApi'
+
+// 5. Komponensek
+import Button from '../../components/Buttons/Button'
+import Navbar from '../../components/Navbar/Navbar'
+
+// 6. Assets
+import Background from '../../assets/backgrounds/Background'
+```
+
+---
+
+## State Management
+
+### Local State
+
+```jsx
+// Egyszerű state
+const [count, setCount] = useState(0)
+
+// Object state
+const [user, setUser] = useState({
+  name: '',
+  email: ''
+})
+
+// Array state
+const [items, setItems] = useState([])
+```
+
+### LocalStorage Használat
+
+**useRequireAuth hook használata auth kezeléshez:**
+
+```jsx
+import useRequireAuth from '../../hooks/useRequireAuth'
+
+const MyComponent = () => {
+  const [username] = useRequireAuth({ 
+    key: 'username', 
+    redirectTo: '/login' 
+  })
+  
+  // username automatikusan szinkronizálva van localStorage-el
+  // Ha nincs username, automatikus redirect /login-re
+}
+```
+
+**Manuális localStorage:**
+
+```jsx
+// Írás
+localStorage.setItem('gameToken', token)
+
+// Olvasás
+const token = localStorage.getItem('gameToken')
+
+// Törlés
+localStorage.removeItem('gameToken')
+```
+
+---
+
+## API Hívások
+
+### API File Struktúra
+
+**Minden API endpoint egy külön file-ban (`userApi.js`, `deckApi.js`, `gameApi.js`):**
+
+```jsx
+// src/api/userApi.js
+import axiosInstance from './axiosInstance'
+
+export const getUserData = async (userId) => {
+  try {
+    const response = await axiosInstance.get(`/users/${userId}`)
+    return response.data
+  } catch (error) {
+    console.error('Error fetching user data:', error)
+    throw error
+  }
+}
+
+export const updateUser = async (userId, userData) => {
+  try {
+    const response = await axiosInstance.put(`/users/${userId}`, userData)
+    return response.data
+  } catch (error) {
+    console.error('Error updating user:', error)
+    throw error
+  }
+}
+```
+
+### API Hívás Komponensben
+
+```jsx
+import { getUserData } from '../../api/userApi'
+
+const MyComponent = () => {
+  const [loading, setLoading] = useState(false)
+  const [error, setError] = useState(null)
+  const [data, setData] = useState(null)
+  
+  const fetchData = async () => {
+    setLoading(true)
+    setError(null)
+    
+    try {
+      const result = await getUserData(userId)
+      setData(result)
+    } catch (err) {
+      setError(err.message || 'Hiba történt')
+    } finally {
+      setLoading(false)
+    }
+  }
+  
+  useEffect(() => {
+    fetchData()
+  }, [userId])
+  
+  if (loading) return <div>Betöltés...</div>
+  if (error) return <div>Hiba: {error}</div>
+  
+  return <div>{/* data megjelenítése */}</div>
+}
+```
+
+---
+
+## Hibakezelés
+
+### Try-Catch Blokkok
+
+```jsx
+const handleSubmit = async () => {
+  try {
+    const response = await createDeck(deckData)
+    // Siker kezelése
+    notifySuccess('Deck sikeresen létrehozva!')
+    goDecks()
+  } catch (error) {
+    // Hiba kezelése
+    const errorMessage = error.response?.data?.message || 'Ismeretlen hiba'
+    setError(errorMessage)
+    notifyError(errorMessage)
+  }
+}
+```
+
+### Toast Notifications
+
+```jsx
+import { notifySuccess, notifyError } from '../../components/Toastify/toastifyServices'
+
+// Siker üzenet
+notifySuccess('✅ Művelet sikeres!')
+
+// Hiba üzenet
+notifyError('❌ Hiba történt!')
+
+// Egyedi konfiguráció
+notifySuccess('Mentve!', { autoClose: 2000 })
+```

+
+## Elnevezési Konvenciók
+
+### JavaScript/React
+
+| Típus | Konvenció | Példa |
+|-------|-----------|-------|
+| Komponensek | PascalCase | `LoginForm`, `DeckCreator` |
+| Függvények | camelCase | `handleClick`, `fetchUserData` |
+| Változók | camelCase | `userName`, `isLoading` |
+| Konstansok | UPPER_SNAKE_CASE | `API_BASE_URL`, `MAX_PLAYERS` |
+| Private változók | _camelCase | `_internalState` |
+| Event handlers | handle + PascalCase | `handleSubmit`, `handleInputChange` |
+| Boolean változók | is/has/can prefix | `isLoading`, `hasError`, `canEdit` |
+
+### CSS Classes (Tailwind)
+
+```jsx
+// Használj explicit class neveket
+<div className="flex items-center justify-between p-4 bg-white rounded-lg shadow-md">
+
+// Kerüld a túl hosszú class stringeket - bontsd több sorra
+<div 
+  className="
+    flex items-center justify-between 
+    p-4 bg-white rounded-lg shadow-md
+    hover:shadow-lg transition-shadow duration-200
+  "
+>
+```
+
+### Fájl Nevek
+
+- **Egyedi komponens**: `LoginForm.jsx` (nem `login-form.jsx`)
+- **Index fájlok**: `index.jsx` (ha könyvtárban több file van)
+- **Utility fájlok**: `randomUtils.js` (camelCase)
+- **API fájlok**: `userApi.js` (camelCase + Api postfix)

+## Összefoglalás - Legfontosabb Szabályok
+
+1. ✅ **MINDIG használd HandleNavigate-et** navigációhoz

+# Frontend Game Completion Implementation
+
+**Date:** November 19, 2025  
+**Status:** ✅ Core gameplay event handlers and action methods implemented
+
+---
+
+## Overview
+
+This document details the completion of missing WebSocket event handlers and action methods in the frontend to enable full gameplay functionality. The implementation ensures that GameScreen can properly receive and respond to all game events from the backend.
+
+---
+
+## Changes Implemented
+
+### 1. GameWebSocketContext.jsx - Added Missing Event Handlers
+
+**Location:** `SerpentRace_Frontend/src/contexts/GameWebSocketContext.jsx`
+
+Added 9 critical gameplay event handlers that were missing from the context:
+
+#### ✅ game:your-turn
+- **Purpose:** Notifies player when it's their turn
+- **Action:** Updates currentTurn state, emits custom event for GameScreen
+- **Implementation:**
+```javascript
+socket.on('game:your-turn', (data) => {
+  log('🎯 Your turn!', data);
+  setCurrentTurn(data.currentPlayer);
+  window.dispatchEvent(new CustomEvent('game:your-turn', { detail: data }));
+});
+```
+
+#### ✅ game:dice-rolled
+- **Purpose:** Broadcasts dice roll results to all players
+- **Action:** Emits custom event for UI to display dice animation
+- **Implementation:**
+```javascript
+socket.on('game:dice-rolled', (data) => {
+  log('🎲 Dice rolled:', data.diceValue, 'by', data.playerName);
+  window.dispatchEvent(new CustomEvent('game:dice-rolled', { detail: data }));
+});
+```
+
+#### ✅ game:guess-result
+- **Purpose:** Receives position guess validation result
+- **Action:** Updates player position if guess was correct, emits event
+- **Implementation:**
+```javascript
+socket.on('game:guess-result', (data) => {
+  log('🎯 Guess result:', data);
+  if (data.correct && data.newPosition !== undefined) {
+    setBoardData(prev => {
+      if (!prev) return prev;
+      const updatedPlayers = { ...prev.playerPositions };
+      updatedPlayers[data.playerName] = data.newPosition;
+      return { ...prev, playerPositions: updatedPlayers };
+    });
+  }
+  window.dispatchEvent(new CustomEvent('game:guess-result', { detail: data }));
+});
+```
+
+#### ✅ game:joker-complete
+- **Purpose:** Receives joker card approval/rejection result
+- **Action:** Updates player position if joker was approved, emits event
+- **Implementation:**
+```javascript
+socket.on('game:joker-complete', (data) => {
+  log('🃏 Joker complete:', data);
+  if (data.approved && data.newPosition !== undefined) {
+    setBoardData(prev => {
+      if (!prev) return prev;
+      const updatedPlayers = { ...prev.playerPositions };
+      updatedPlayers[data.playerName] = data.newPosition;
+      return { ...prev, playerPositions: updatedPlayers };
+    });
+  }
+  window.dispatchEvent(new CustomEvent('game:joker-complete', { detail: data }));
+});
+```
+
+#### ✅ game:luck-consequence
+- **Purpose:** Receives luck card consequence (extra turns, lost turns, position changes)
+- **Action:** Updates player position if consequence includes movement, emits event
+- **Implementation:**
+```javascript
+socket.on('game:luck-consequence', (data) => {
+  log('🍀 Luck consequence:', data);
+  if (data.newPosition !== undefined && data.playerName) {
+    setBoardData(prev => {
+      if (!prev) return prev;
+      const updatedPlayers = { ...prev.playerPositions };
+      updatedPlayers[data.playerName] = data.newPosition;
+      return { ...prev, playerPositions: updatedPlayers };
+    });
+  }
+  window.dispatchEvent(new CustomEvent('game:luck-consequence', { detail: data }));
+});
+```
+
+#### ✅ game:ended
+- **Purpose:** Announces game end with winner and final scores
+- **Action:** Updates gameState with winner and final scores, emits event for winner modal
+- **Implementation:**
+```javascript
+socket.on('game:ended', (data) => {
+  log('🏁 Game ended! Winner:', data.winner);
+  setGameState(prev => ({
+    ...prev,
+    status: 'finished',
+    winner: data.winner,
+    finalScores: data.scores
+  }));
+  window.dispatchEvent(new CustomEvent('game:ended', { detail: data }));
+});
+```
+
+#### ✅ game:extra-turn-remaining
+- **Purpose:** Notifies player they have extra turn(s) from luck consequences
+- **Action:** Emits event for UI notification
+- **Implementation:**
+```javascript
+socket.on('game:extra-turn-remaining', (data) => {
+  log('⭐ Extra turn remaining:', data);
+  window.dispatchEvent(new CustomEvent('game:extra-turn-remaining', { detail: data }));
+});
+```
+
+#### ✅ game:players-skipped
+- **Purpose:** Broadcasts when players are skipped due to lost turn consequences
+- **Action:** Emits event for UI notification
+- **Implementation:**
+```javascript
+socket.on('game:players-skipped', (data) => {
+  log('⏭️ Players skipped:', data.skippedPlayers);
+  window.dispatchEvent(new CustomEvent('game:players-skipped', { detail: data }));
+});
+```
+
+#### ✅ game:cleanup-complete
+- **Purpose:** Confirms cleanup after game end
+- **Action:** Emits event for final UI state reset
+- **Implementation:**
+```javascript
+socket.on('game:cleanup-complete', (data) => {
+  log('🧹 Cleanup complete:', data);
+  window.dispatchEvent(new CustomEvent('game:cleanup-complete', { detail: data }));
+});
+```
+
+---
+
+### 2. GameWebSocketContext.jsx - Added Missing Action Methods
+
+Added 4 critical action methods that players and gamemaster need:
+
+#### ✅ submitAnswer(answer)
+- **Purpose:** Submit answer to question card
+- **Parameters:** `answer` - Player's answer (type depends on card type: string for QUIZ/OWN_ANSWER, array for SENTENCE_PAIRING, boolean for TRUE_FALSE, number for CLOSER)
+- **Emits:** `game:card-answer` with gameCode and answer
+- **Returns:** Boolean (success/failure)
+
+```javascript
+const submitAnswer = useCallback((answer) => {
+  const socket = socketRef.current;
+  if (!socket || !isConnected) {
+    warn('⚠️ Cannot submit answer: not connected');
+    return false;
+  }
+  log('📝 Submitting answer:', answer);
+  socket.emit('game:card-answer', { gameCode: gameState?.gameCode, answer });
+  return true;
+}, [isConnected, gameState?.gameCode]);
+```
+
+#### ✅ submitPositionGuess(guessedPosition)
+- **Purpose:** Submit position guess after correct answer
+- **Parameters:** `guessedPosition` - Number (0-99) representing guessed board position
+- **Emits:** `game:position-guess` with gameCode and guessedPosition
+- **Returns:** Boolean (success/failure)

+    reason 
+  });
+  return true;
+}, [isConnected, isGamemaster, gameState?.gameCode]);
+```
+
+---
+
+### 3. GameWebSocketContext.jsx - Updated Context Value Export
+
+Updated the context value to export all new methods:
+
+```javascript
+const value = {
+  socket: socketRef.current,
+  isConnected,
+  gameState,
+  players,
+  boardData,
+  currentTurn,
+  error,
+  isGamemaster,

+  approvalStatus,
+  // Connection management
+  connect,
+  disconnect,
+  // Methods
+  rollDice,
+  sendMessage,
+  setReady,
+  leaveGame,
+  approvePlayer,
+  rejectPlayer,
+  submitAnswer,           // ✅ NEW
+  submitPositionGuess,    // ✅ NEW
+  approveJoker,           // ✅ NEW
+  rejectJoker,            // ✅ NEW
+  addEventListener,
+  removeEventListener,
+};
+```
+
+---
+
+### 4. GameScreen.jsx - Fixed Action Method Calls
+
+**Location:** `SerpentRace_Frontend/src/pages/Game/GameScreen.jsx`
+
+#### Fixed handleSubmitAnswer
+**Before:**
+```javascript
+const handleSubmitAnswer = useCallback((answer) => {
+  if (currentCard?.id) {
+    submitAnswer(currentCard.id, answer)  // ❌ Wrong parameters
+  }
+}, [currentCard?.id, submitAnswer])
+```
+
+**After:**
+```javascript
+const handleSubmitAnswer = useCallback((answer) => {
+  console.log('📝 Válasz beküldve:', answer)
+  submitAnswer(answer)  // ✅ Correct - backend extracts gameCode from context
+}, [submitAnswer])
+```
+
+#### Fixed handleApproveJoker
+**Before:**
+```javascript
+const handleApproveJoker = useCallback(async (jokerRequest) => {
+  approveJoker(jokerRequest.playerId, jokerRequest.cardId, jokerRequest.requestId)  // ❌ Wrong parameters
+  setIsJokerModalOpen(false)
+}, [approveJoker])
+```
+
+**After:**
+```javascript
+const handleApproveJoker = useCallback(async (jokerRequest) => {
+  console.log('✅ Joker feladat jóváhagyva:', jokerRequest)
+  approveJoker(jokerRequest.requestId)  // ✅ Correct - only requestId needed
+  setIsJokerModalOpen(false)
+}, [approveJoker])
+```
+
+#### Fixed handleRejectJoker
+**Before:**
+```javascript
+const handleRejectJoker = useCallback(async (jokerRequest) => {
+  rejectJoker(jokerRequest.playerId, jokerRequest.cardId, jokerRequest.requestId)  // ❌ Wrong parameters
+  setIsJokerModalOpen(false)
+}, [rejectJoker])
+```
+
+**After:**
+```javascript
+const handleRejectJoker = useCallback(async (jokerRequest) => {
+  console.log('❌ Joker feladat elutasítva:', jokerRequest)
+  rejectJoker(jokerRequest.requestId, 'Joker rejected by gamemaster')  // ✅ Correct
+  setIsJokerModalOpen(false)
+}, [rejectJoker])
+```
+

+
+## Architecture Benefits
+
+### ✅ Centralized Event Handling
+All WebSocket events are handled in the context, ensuring:
+- Single source of truth for game state
+- Consistent state updates across all components
+- Easy debugging with centralized logging
+
+### ✅ Custom Event Bridge
+Events are re-emitted as CustomEvents via `window.dispatchEvent()`, allowing:
+- GameScreen to add specific UI logic without modifying context
+- Separation of concerns (state management vs UI presentation)
+- Multiple components can listen to the same events independently
+
+### ✅ Persistent Connection
+Socket connection persists across navigation (Lobby → GameScreen), ensuring:
+- No disconnections during page transitions
+- Gamemaster can start game without socket dropping
+- Real-time updates continue seamlessly
+
+### ✅ Type Safety & Validation
+All action methods include:
+- Connection state checks (`isConnected`)
+- Authorization checks (`isGamemaster` for approval methods)
+- Error logging for debugging
+- Boolean return values for success/failure
+
+---
+
+## Testing Checklist
+
+### ✅ Event Handler Tests
+- [ ] Test `game:your-turn` - Turn indicator updates
+- [ ] Test `game:dice-rolled` - Dice animation triggers
+- [ ] Test `game:guess-result` - Position updates on correct guess
+- [ ] Test `game:joker-complete` - Position updates on approved joker
+- [ ] Test `game:luck-consequence` - Position updates from luck cards
+- [ ] Test `game:ended` - Winner modal displays with final scores
+- [ ] Test `game:extra-turn-remaining` - Extra turn notification
+- [ ] Test `game:players-skipped` - Skip notification
+- [ ] Test `game:cleanup-complete` - Cleanup confirmation
+
+### ✅ Action Method Tests
+- [ ] Test `submitAnswer()` - Answer submission for all card types (QUIZ, SENTENCE_PAIRING, TRUE_FALSE, CLOSER, OWN_ANSWER)
+- [ ] Test `submitPositionGuess()` - Position guess submission
+- [ ] Test `approveJoker()` - Gamemaster approval (requires isGamemaster)
+- [ ] Test `rejectJoker()` - Gamemaster rejection (requires isGamemaster)
+
+### ✅ Integration Tests
+- [ ] Complete game flow: Start → Dice → Card → Answer → Position Guess → Next Turn
+- [ ] Joker flow: Joker drawn → Request sent → Gamemaster decision → Position update
+- [ ] Luck flow: Luck card → Consequence applied → Position/turn updated
+- [ ] End game flow: Player reaches finish → Winner announced → Scores displayed

+# 🔧 Game Fixes Applied - November 19, 2025
+
+## Issues Fixed
+
+### 1. ✅ Cannot Answer Card Questions
+**Problem**: Card modal wasn't receiving data properly from backend  
+**Root Cause**: Backend sends `game:card-drawn-self` event with nested structure `{ cardData: {...}, timeLimit: 60 }` but frontend was trying to access fields directly  
+**Solution**: 
+- Updated `handleCardDrawn` in GameScreen.jsx to properly extract `cardData` from nested structure
+- Added support for `hint` field
+- Properly handles both `game:card-drawn` and `game:card-drawn-self` events
+
+**Files Modified**:
+- `SerpentRace_Frontend/src/pages/Game/GameScreen.jsx` (lines 249-263)
+
+```javascript
+const handleCardDrawn = (data) => {
+  // Backend sends cardData nested in game:card-drawn-self event
+  const cardData = data.cardData || data;
+  setCurrentCard({
+    id: cardData.cardId || cardData.id,
+    type: cardData.cardType || cardData.type,
+    question: cardData.question || cardData.text || cardData.statement,
+    answerOptions: cardData.answerOptions || cardData.options || [],
+    correctAnswer: cardData.correctAnswer,
+    hint: cardData.hint,
+    points: cardData.points || 0,
+    timeLimit: data.timeLimit || cardData.timeLimit || 60
+  })
+  setIsCardModalOpen(true)
+}
+```
+
+---
+
+### 2. ✅ Player Turn Indicator Not Working
+**Problem**: Turn indicator wasn't updating properly  
+**Root Cause**: Frontend didn't know which player was the current user to compare with `gameState.currentPlayer`  
+**Solution**: 
+- Added `playerIdentifier` state to GameWebSocketContext
+- Decode gameToken on connect to extract `userId` or `playerName`
+- Added `isMyTurn` computed value that compares `gameState.currentPlayer` with `playerIdentifier`
+
+**Files Modified**:
+- `SerpentRace_Frontend/src/contexts/GameWebSocketContext.jsx` (lines 16, 57-62, 88-97, 488-489)
+
+```javascript
+// In GameWebSocketContext
+const [playerIdentifier, setPlayerIdentifier] = useState(null);
+
+// Decode token to get player identifier
+try {
+  const payload = JSON.parse(atob(gameToken.split('.')[1]));
+  const identifier = payload.userId || payload.playerName;
+  setPlayerIdentifier(identifier);
+  log('🎮 Player identifier:', identifier);
+} catch (err) {
+  logError('Failed to decode game token:', err);
+}
+
+// Check if it's the current player's turn
+const isMyTurn = useMemo(() => {
+  if (!gameState?.currentPlayer || !playerIdentifier) return false;
+  return gameState.currentPlayer === playerIdentifier;
+}, [gameState?.currentPlayer, playerIdentifier]);
+```
+
+---
+
+### 3. ✅ Current Player Name Not Shown in Indicator
+**Problem**: Turn indicator only showed "Betöltés..." or player ID instead of player name  
+**Root Cause**: Inconsistent player ID format (some by `userId`, some by `playerName`)  
+**Solution**: 
+- Updated player lookup to check multiple possible ID formats
+- Highlights current player name in green when it's your turn
+- Shows "← Te vagy!" (It's you!) indicator next to your name
+
+**Files Modified**:
+- `SerpentRace_Frontend/src/pages/Game/GameScreen.jsx` (lines 470-476)
+
+```javascript
+{currentTurn && (
+  <div className="text-gray-400 text-xs mt-1">
+    🎯 Köron: <span className={`font-bold ${isMyTurn ? 'text-green-400' : 'text-white'}`}>
+      {players.find(p => p.id === currentTurn || p.playerName === currentTurn || p.name === currentTurn)?.name || currentTurn || 'Betöltés...'}
+    </span>
+    {isMyTurn && <span className="ml-2 text-green-400 animate-pulse">← Te vagy!</span>}
+  </div>
+)}
+```
+
+---
+
+### 4. ✅ Dice Shown Even When Not Player's Turn
+**Problem**: Dice was always interactive regardless of whose turn it was  
+**Root Cause**: No turn validation on dice display  
+**Solution**: 
+- Added conditional rendering based on `isMyTurn` flag
+- When it's your turn: Shows green pulsing text "🎯 A te köröd! Kattints a kockára dobáshoz!"
+- When it's NOT your turn: Shows gray text "⏳ Várd meg a köröd..." and dice is disabled with 50% opacity and `pointer-events-none`
+
+**Files Modified**:
+- `SerpentRace_Frontend/src/pages/Game/GameScreen.jsx` (lines 609-625)
+
+```javascript
+{isMyTurn ? (
+  <>
+    <p className="text-green-400 text-sm mb-4 font-bold animate-pulse">
+      🎯 A te köröd! Kattints a kockára dobáshoz!
+    </p>
+    <Dice onRoll={handleDiceRoll} />
+  </>
+) : (
+  <>
+    <p className="text-gray-500 text-sm mb-4">
+      ⏳ Várd meg a köröd...
+    </p>
+    <div className="opacity-50 pointer-events-none">
+      <Dice onRoll={handleDiceRoll} />
+    </div>
+  </>
+)}
+```
+
+---
+
+## Additional Improvements
+
+### Debug Panel Enhancement
+Added debug information to help verify turn system:
+- **🆔 My ID**: Shows current player's identifier (userId or playerName)
+- **✅ Is My Turn**: Shows YES/NO to quickly verify turn detection
+
+**Files Modified**:
+- `SerpentRace_Frontend/src/pages/Game/GameScreen.jsx` (lines 643-644)
+
+---
+
+## Technical Details
+
+### Token Structure
+The gameToken is a JWT containing:
+```json
+{
+  "gameId": "uuid",
+  "gameCode": "ABC123",
+  "playerName": "Player1",
+  "isAuthenticated": true/false,
+  "userId": "uuid" // only for authenticated players
+}
+```
+
+### Player Identification Logic
+Backend uses: `playerIdentifier = socket.userId || socket.playerName`  
+Frontend now extracts: `payload.userId || payload.playerName` from decoded token
+
+This ensures both authenticated users (with userId) and guest players (with only playerName) work correctly.
+
+---
+
+## Testing Checklist
+
+### ✅ Card System
+- [ ] Draw a card and verify modal opens with question
+- [ ] Verify answer options display correctly (for quiz cards)
+- [ ] Submit answer and verify it's sent to backend
+- [ ] Check hint displays if available
+- [ ] Verify timer countdown works
+
+### ✅ Turn System
+- [ ] Game starts and first player sees "🎯 A te köröd!"
+- [ ] Other players see "⏳ Várd meg a köröd..."
+- [ ] Turn indicator shows correct player name
+- [ ] "← Te vagy!" appears next to your name when it's your turn
+- [ ] Name is highlighted in green when it's your turn
+
+### ✅ Dice Control
+- [ ] Dice is interactive (clickable) only on your turn
+- [ ] Dice is grayed out and disabled when not your turn
+- [ ] Text changes from green "A te köröd!" to gray "Várd meg a köröd..."
+
+### ✅ Multi-Player Testing
+- [ ] Test with 2+ authenticated players
+- [ ] Test with guest players (no login)
+- [ ] Test with mix of authenticated and guest players
+- [ ] Verify turn rotation works correctly
+- [ ] Each player can only act on their turn
+
