Once your tournament is published, you can update the scores for games. To update game scores:
1. Open up your tournament and go to the games tab
2. Click 'Set Score'
3. Update the score for the game and make sure the status is 'Completed'. Hit Save when you're done!
You will see the game score update on the games list, the bracket will update, and these changes will also be reflected on your tournament's webpage.
