The team score is the total amount of levels and stages in the Champion’s League that players on a team have completed! The more levels and stages all players in your team complete, the higher your team's score will be. Team Helps are not included in the score.
For example, let's say a team has 5 players.
Player 1 - Level 200, 3 Stages
Player 2 - Level 200, 2 Stages
Player 3 - Level 100
Player 4 - Level 50
Player 5 - Level 10
This team's score is 565.
If your team score is tied with another team, the team that reached the score first will have a higher rank.
