+2. **Bubble Rookie** - Pop 100 bubbles (10 points)
+3. **Bubble Master** - Pop 1,000 bubbles (25 points)
+4. **Bubble Legend** - Pop 5,000 bubbles (50 points)

+6. **Speed Demon** - Score 1,000 points in under 2 minutes (25 points)
+7. **Perfect Session** - Complete session without missing bubbles (20 points)
+
+### 📊 Leaderboards (4 total)
+1. **High Score** - Highest score in regular mode
+2. **Zen Mode Duration** - Longest time spent in Zen mode
+3. **Total Bubbles Popped** - Lifetime bubble count
+4. **Longest Session** - Longest single game session
+
+### 🖥️ User Interface
+- **Settings Integration**: New Google Play Games section in settings
+- **Sign In/Out**: Easy authentication with Google Play Games
+- **Direct Access**: Buttons to view achievements and leaderboards
+- **Status Display**: Shows signed-in player name and status
+
+### 🔧 Technical Implementation
+- **Android Configuration**: Updated AndroidManifest.xml and build.gradle.kts
+- **Dependencies**: Added games_services package
+- **Error Handling**: Comprehensive error handling and user feedback
+- **Performance**: Optimized tracking to not impact game performance
+
+## 🚧 Next Steps Required
+
+### 1. Google Play Console Setup
+- Create Google Play Games project
+- Configure all 7 achievements with exact IDs
+- Set up all 4 leaderboards with exact IDs
+- Get your App ID and update `strings.xml`
+
+### 2. App Signing
+- Upload SHA-1 fingerprint to Google Play Console
+- Ensure proper app signing for release
+
+### 3. Testing
+- Test with internal testing track
+- Verify all achievements trigger correctly
+- Test leaderboard submissions
+
+## 📱 How It Works
+
+### For Players
+1. Open ZenTap → Settings
+2. Find "Google Play Games" section
+3. Tap "Sign In" to authenticate
+4. Play the game normally - achievements unlock automatically
+5. View progress via "Achievements" and "Leaderboards" buttons
+
+### For Developers
+- All tracking happens automatically during gameplay
+- No additional code needed for basic functionality
+- Achievements check on every bubble pop
+- Leaderboard submissions happen at session end
+- Statistics tracked include: bubbles popped, session time, perfect sessions
