About Aquar.io

Aquar.io is a multiplayer underwater game and the sequel to Oceanar.io. You start as a small Queen fish and grow a school of ocean creatures around you. Some sea dwellers will join your school, while others turn hostile and fight back. The game runs in the browser with no download, so you can jump into a round right away.

The fun comes from managing your school as a team. You send creatures into battle, merge them into stronger units, or devour them to give your Queen fish experience. There are five levels of evolution, and each one unlocks a special ability. Keep your Queen safe, because if she dies, the round is over.

Tips for Aquar.io

  • Your Queen fish is your life, so keep her behind your school instead of leading attacks with her.
  • Merge creatures before big fights, since merged creatures are much stronger than single ones.
  • Devour part of your school when you feel safe to push your Queen toward the next evolution level and its new ability.
  • Zoom out with the scroll wheel to spot hostile creatures and other players before they reach you.
