In the Mists of Carcassonne, you either win or lose as a team. There is no final scoring. The end of the game can be triggered in various ways:

Victory

You reach or pass the goal tile on the scoring track. You have scored enough points (50 in Level 1) and won! Congratulations, you can now advance to the next Level.

Defeat

1. There are no tiles left in the supply, but you haven’t reached the goal tile yet: You have lost, unfortunately, and will need to try the Level again.

2. There are fewer ghosts left in the supply than you need to place on a tile: You have lost, unfortunately, and will need to try the Level again.
