Aquarium King

Start as a small fish and discover a big underwater adventure!

In Aquarium King, swim, eat smaller fish and grow while avoiding larger predators. Use your boost, watch for danger and find the best route. Your fish's appearance changes as it evolves.

EXPLORE THE CAMPAIGN
Play 60 stages across five environments: Glass, Coral, Shipwreck, Abyss and Radioactive. Complete feeding, pearl, ring and school challenges, reach the exit marked by a star and face each region's boss.

DIVE INTO ROGUELITE
Explore a continuous ocean with varied encounters and areas. Choose mutations during your run, try new combinations and beat your personal records.

CARE FOR THE KING'S AQUARIUM
Collect fish, feed your collection and arrange your aquarium. Unlock appearances through achievements in the campaign, Roguelite and aquarium.

LEARN BY PLAYING
Guided Training teaches the controls through practical activities: swimming, eating, boosting, passing through rings and trying Frenzy.

PLAY YOUR WAY
Use the virtual joystick or choose tap-to-move and relative drag. Adjust sound, effects and visual quality. The game supports eleven languages.
