Unlike missions, events are challenges available for anyone to compete for, regardless of your current progression. There is a new event every few days and the objectives always change. To take part in the events and appear in the leaderboards, you will need to login to Cloud Save. You will be asked to equip a specific shark or item and your score will display in the public leaderboard. Your event score displays at the bottom of the screen during a game session. You can know more about the active event by tapping on the green button on the right of your start screen. The timer below the button shows you how long you have left before the contest ends.
