The object of the game is to solve puzzles and earn coins to set up and decorate a virtual aquarium. Using in-game currency the player is able to purchase different species of fish, decorations, and "comfort" items to make the environment more pleasant for pet fishes. Filling all of the three meter gauges measuring the progress will unlock one of the trophies: bronze, silver, or gold. Adorned and themed tanks can be used as a smartphone screensaver.
