World Tour is a cooperative event. You can only participate in it after becoming a member of a team.
In this event, you and your teammates need to collect rudders. For each standard level completed, you get one rudder. Completing a hard or super hard level rewards you with 2 or 3 rudders, respectively.
All the rudders collected by you and your teammates are added to the team's shared pool. When the required amount is reached, all the team members receive rewards. The players who made the biggest contributions to the total amount of rudders receive additional individual rewards.
