Aquar.io
Aquar.io is a multiplayer fish game where you lead a whole school of fish as their Queen.
It is the sequel to Oceanar.io, and it swaps the usual lone blob for something cleverer. Everything you gather grows your school, and anything that kills your Queen ends the run.
How to Play Aquar.io?
Your Queen is the fish you steer, and the school follows her. Feed her to grow your numbers and protect her, because the run ends the moment she dies. Some ocean creatures you meet will join your school, and others will come for you.
The clever part is what you do with the fish you have collected. You can throw them at enemies, pull them in tight to merge them into stronger creatures, or devour your own school to feed the Queen experience. Enough experience takes her through five evolutions, each unlocking a new ability. There are free-for-all and team areas, a spectate mode if you want to watch the top players first, and a top 1000 leaderboard.
Tips and Tricks:
- Protect the Queen: Your school is replaceable. She is not.
- Merge before big fights: A tighter, stronger school wins against a loose one.
- Devour when it counts: Converting your school to experience can unlock the next evolution.
