About This Game

Equip Your Polar Bear. Build the Ultimate King.

Give your polar bear weapons, shields, and all kinds of equipment to create the strongest fighter possible.

Point a sword straight ahead.
Surround the entire body with shields.
Add more boots and charge forward at incredible speed.
Attach weights to create a build that is harder to knock away.

Where you place each piece of equipment—and the angle you attach it at—is entirely up to you.

Once your polar bear is complete, it will automatically battle polar bears created by other players.

There is no need to wait for an opponent in real time.
Download another player’s equipment data and enjoy asynchronous online battles whenever you like.

Placement Is Strategy

Equipment can be attached not only to the polar bear itself, but also to other pieces of equipment.

Attach another sword to the tip of a sword.
Hide a gun behind a shield.

Within a limited equipment-cost budget, you must balance offense, defense, speed, and stability.

Your build may look a little strange, but if it wins, it works.

Unpredictable 2D Physics Battles

When the battle begins, both polar bears automatically move toward each other.

When swords collide, both fighters are knocked backward.

Crashing into a wall causes damage.

The last polar bear standing becomes the King.

Asynchronous Ranked Matches

Every player starts with 100 Rank Points.

In Ranked Matches, you will battle against player data from opponents with a similar rank.

Winning increases your Rank Points, while losing decreases them.
The amount gained or lost depends on the rank difference between you and your opponent.

Defeat stronger opponents and climb to the top of the rankings.

Practice Against CPU Opponents

Before entering online battles, you can test your equipment setup against fixed CPU opponents.

Experiment with weapon angles, shield placement, and knockback behavior as you fine-tune your own unique build.

CPU battles do not affect your Rank Points.

Available Equipment

Sword: A basic weapon that deals damage when it touches an opponent.

Gun: A ranged weapon that can attack from a distance.

Shield: A defensive item that blocks enemy weapons.

Weight: Reduces knockback.

More equipment is planned for future updates.

Free to Play

SHIROKUMA KING can be enjoyed completely free from beginning to end.

If you enjoy the game, you can optionally purchase a supporter item to help fund future development and updates.

Supporter items provide no gameplay advantages and do not affect competitive balance.

Simply playing the game is already more than enough support.

Now, give your polar bear some weapons.

It will figure out the rest.
