Oceanar.io

Oceanar.io is a multiplayer underwater IO game where you control a school of fish and compete against other players in the ocean depths. Your mission is to feed your Queen fish, grow your school, and become the most powerful swarm in the sea.

How to Play

You start with a small school of fish led by a Queen. Move your mouse to guide your swarm through the ocean. Eat smaller creatures and food to grow your school bigger and stronger.

Controls

• Move: Mouse cursor

• Attack: Hold left mouse button or W key

• Merge: Hold right mouse button or Spacebar

School Mechanics

What makes Oceanar.io unique is the swarm system. You don't control a single fish — you control an entire school. As you eat and grow, your school gets bigger with more fish following your Queen. The merge mechanic lets you consolidate your school for more concentrated power.

Tips

• Focus on eating Queen fish from defeated players — they give the most growth

• Use the attack ability to take on other players' schools

• Merge your fish when you need concentrated firepower

• Stay away from schools much larger than yours

• Check the leaderboard to see how you rank against other players

• Choose a server close to your location for the best experience
