Each regatta features a certain number of tasks that can be completed. Each task is worth a certain amount of points. The Neighborhood to score the most points in its group during the regatta wins.
If you don't want to complete a task, you can remove it from the task board. A new task will appear in 30 minutes.
If you accept the task but fail to complete it in the specified time, you will not receive points for this task and the task will be failed. It will be marked in gray in the list of completed tasks. Also, one attempt will be subtracted from the number of tasks that can be performed in the current regatta.
