You can join a team once you have reached player level 4. You can then easily join a team by using the ‘Team’ tab located at the bottom of the main game screen. There, you will find teams to join, or use the search button to find and join a team.

The Join button can be used to join a team if there is an available spot. However, if a team is ‘closed,’ you will need to wait for your request to be approved by the Team Leader.
