Game Description


Explore the brand new ocean adventure, Splash: Underwater Sanctuary, from the makers of Flutter!

Dive into an expansive ocean world in desperate need of repair. This underwater sanctuary needs your help to nurture it from a dark and lifeless existence into a vibrant and diverse ecosystem. In order to accomplish this feat, you will need to grow a multitude of sea creatures through their lifecycles from eggs to adults. Along the way be sure to keep your Aquapedia handy, as you’ll find exciting real life facts about each species you uncover at every turn of the page. Watch in wonder as your sanctuary comes to life, teeming with creatures that are both visually stunning and unique in personality and behavior.

So, what are you waiting for? Take the plunge! Splash is overflowing with eye-catching fish, beautiful ocean environments and relaxing gameplay that is sure to keep you entertained for hours to come.

• Grow real life creatures from Angelfish and Butterflyfish to Seahorses and Jellyfish.
• Explore and unlock new areas and expand your population!
• Fill your Aquapedia to catalog your entire undersea collection.
• Restore the balance by releasing your adult fish into the greater ocean.
