+**Game End Scenarios**:
+
+1. **Normal Win** (Player reaches position 100):
+   ```typescript
+   {
+     winner: "player-uuid",
+     winnerName: "Alice",
+     message: "🎉 Alice won the game! Congratulations!",
+     finalPositions: [...],
+     timestamp: "2025-11-06T..."
+   }
+   ```
+
+2. **Gamemaster Disconnect** (Game cancelled):
+   ```typescript
+   {
+     reason: "gamemaster_left",
+     gamemasterName: "Bob",
+     message: "🎭 Gamemaster Bob left. Game has ended.",
+     timestamp: "2025-11-06T..."
+   }
+   ```
+   
+   **Behavior**:
+   - Game immediately cancelled when gamemaster disconnects
+   - All players notified via `game:ended` event
+   - Database updated: `state = CANCELLED`, `enddate = now`
+   - All Redis data and socket connections cleaned up
+   - No winner recorded (game didn't complete normally)
