About This Game

“A quiet moment beneath the sea, where I meet my own fishy friends.”

Polarium

Relaxing background idle gameplay

“Polarium grows little by little, just by staying by your side.”

Even while you leave the window open and focus on other tasks,
your fish quietly grow, and pearls slowly accumulate.

Like a small aquarium by the window,
your ocean friends gently drift across the screen.
And when you return,
you’ll find joy in the subtle changes beneath the sea.

Features

Invite new ocean friends!

“Who will come next?”

In the depths of the sea, you can invite unique fish through the clam-shaped gate — each one with a different look every time!

Patterns, colors, fins, and even expressions are all randomly generated.

The more you collect, the more your collection grows, filling your own underwater world with new friends.

Share the love

“The magic of two lives coming together to create a new one.”

When you breed two different fish,
you might discover rare or uniquely shaped new ones.

The results of each combination are yours to uncover!
Enjoy the thrill of collection and the joy of experimentation, all in one.

The ocean keeps growing!

“Your underwater base grows slowly, but surely.”

To collect or breed fish, you’ll need special buildings.

Upgrade various facilities like your base, the Love Rock, and the Clam Gate to meet more fish — faster and in greater variety.

The more you upgrade, the livelier your underwater world becomes!

Pearl gifts from your fish

“Little treasures gifted by your fish.”

Over time, your fish quietly produce pearls.
These pearls are a key resource used to upgrade buildings and discover rare fish.

Gather these precious treasures slowly and gently beneath the sea,
and grow your own little underwater kingdom.
