Select your preferred mode in Settings Then Click on Start to start the game. Once The game starts the ocean will carry trash down with its waves. If you click on the trash it will give you points based on the mode and how dangerous it is for marine mammals., and once it hits the sand the trash gets lost in it and you lose points. Once you get enough points you can buy power ups in the shop which can help you in the game and to gather more points.
