Why Build Your Aquarium Is So Fun
Turning an empty building into a glowing aquarium full of fish is relaxing and satisfying.
Play on Any Device
Build Your Aquarium runs in your browser on PC, Mac, Chromebook and tablets, with nothing to download. Your progress is saved automatically, so you can stop at any time and continue later. Short levels make it perfect for a few minutes of fun between other activities.
New Halls and Exhibits
Unlock new halls like a shark tunnel, a jellyfish room or a coral reef. Each one costs more but brings in many more visitors. Building them in a smart order speeds up your growth.
Little touches like benches and gift shops keep visitors happy and add extra income.
Why Players Love It
Every new creature you add makes the aquarium more colourful and lively, and some rare ones are real crowd favourites. The controls are simple enough for anyone, yet there is always a new goal to reach, which keeps players coming back day after day.
