In the Regatta task board, you may come across different types of tasks:
Ordinary tasks can bring you up to 135 points. There can be tasks like sending fully loaded planes, fulfilling helicopter orders, feeding animals, etc in the regatta. Relay tasks are an exception — they can earn a co-op up to 145 points. You can read more about relay tasks in the How do relay tasks work? article.
Some of the tasks are marked with a flag icon — these are special seasonal tasks. You will receive more tokens that allow to buy unique decorations and rewards for completing these tasks.
In addition, there are mini-game tasks in the regatta that can bring you up to 150 points. But be careful, such tasks must be completed within a few hours, otherwise they will not be counted.
